METHODS AND REACTORS FOR PRODUCING MULTIPLE DISINFECTING AGENTS FROM OILS

FIELD OF THE DISCLOSURE

Described herein are methods for producing multiple disinfecting agents from oils, including waste oils, and reactors for producing multiple disinfecting agents from the oils.

BACKGROUND OF THE DISCLOSURE

Many natural oils have antimicrobial benefits, ranging from antibacterial to antiviral and sporicidal. It is standard industry practice to distill natural oils and extract a single chemical species that, for any particular oil, represents either the highest yield or most valuable constituent. A byproduct of this practice is exhibited in pyrolytic fumigation where a specific feedstock is pyrolyzed at a specific temperature to produce a specific fumigation agent.

The present disclosure differs from these known industry practices, for example, by recognizing that antimicrobial and sporicidal oils have numerous chemical compounds that can be extracted with varying degrees of effectiveness for a particular target. The present disclosure focuses on extracting multiple, in and some cases many, active chemical species. In combination, these multiple active chemical species have a higher likelihood of disinfection given a target or multiple targets. In some embodiments, this extraction of chemical compounds occurs simultaneously, such that the compounds are immediately available for application. In some embodiments, this extraction of chemical compounds occurs subsequently, such that the compounds are produced and stored without having to individually extract and separately formulate the desired antimicrobial compounds.

Extracting multiple chemical species from an essential oil has been attempted previously; however, there are many deficiencies with prior attempts. For example, previous attempts do not lend themselves to the thermal ranges, controllability, or dwell times needed for efficient or sufficient multi-constituent chemical extraction for the production of disinfectant compounds. Further, previous mechanisms are not meant to employ raw natural oils, which can degrade the systems' ability to function over time.

The present disclosure further differs from these known industry practices by employing waste oils in some instances. Waste oils may provide safe fumigants. But previous mechanisms are not meant to employ waste or recycled oils, which can degrade the systems' ability to function, either rapidly or over time.

The present disclosure still further differs from these known industry practices, for example, by describing a fumigation system designed to disinfect agricultural and urban open spaces and large enclosures. It is an object of this disclosure to provide a powered fumigation system that promotes the eradication of harmful spores and microbes. The system of the present disclosure includes, in some instances, three subsystems: a first subsystem designed for storage, a second subsystem designed for fumigation, and a third subsystem designed for extraction.

The system and methods of the present disclosure have the following advantages: simplicity, utility, and breadth of application. The system and methods do not require a skilled operator. In some embodiments, the oil used as a feedstock is sourced from nearly any natural oil and need not be refined. The method amplifies the fumigant's effectiveness by ensuring that multiple species of active agents are, in some instances, employed from a single species of oil.

Described herein are methods for producing multiple disinfecting agents from oils and reactors for producing multiple disinfecting agents from oils. The present disclosure is economically and logistically advantageous compared to previous solutions. Specific advantages of the present disclosure include selective extraction of disinfecting agents and increased efficacy of disinfecting agents. Additional advantages include direct application of disinfecting agents to target environments without the need for further storage or transport.

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 is an exemplary embodiment of a representative configuration of a reactor in accordance with the present disclosure.

DETAILED DESCRIPTION OF THE DRAWINGS

One reactor 100 in accordance with the present disclosure is shown in FIG. 1. The reactor includes an air compressor 104 that draws air atmospheric pressure and temperature from an air inlet 102, such as an air reservoir, pressurizes the air, and passes it to a furnace coil 110. At the furnace coil 110, the pressurized air is heated, such as from 25° C. to 512° C. The reactor also includes a pump 108 that draws oil from an oil tank 106 housing an oil at atmospheric pressure and temperature. The pump 108 may draw oil from an oil tank at a flow rate of 9000 mL/min. The pump 108 passes the oil to a reactor 112 where it is combined with the pressurized air from the furnace coil 110. In the reactor 112, the flow is reduced, such as to 0.28 mL/min, and the temperature is maintained at an elevated temperature, such as 512° C. Disinfecting agents are produced at an output of the reactor 112, such as at an elevated temperature of 512° C. and a flow rate of 9000 mL/min. The disinfecting agents are passed through a cooling coil 114, such as a water-cooled coil or a u-trap/coil water bath, and such as at −4° C. and 4.9 mL/min. The cooling coil 114 produces deentrained particles, such as at 25° C. and 9000 mL/min, which are passed to an output of the cooling coil 114 at the same conditions. The particles outputted by the cooling coil 114 pass through a condenser 116 to produce a condensed product, such as at atmospheric pressure, 25° C. and 0.14 mL/min, that flows to a condenser catch 118, such as a basin. Also produced from the condenser 116 are other products that exit by an outlet 120, such as a vent, and such as at atmospheric pressure, 25° C., and 9000 mL/min. The other products exit by the outlet 120 and flow to atmospheric conditions.

Reactions

In some embodiments, the reactions occur in a super-heated fumigation apparatus. A super-heated fumigation apparatus decomposes oils into a variety of disinfecting agents. This is accomplished at different temperatures and air flows in different reaction zones, creating an opportunity to introduce the oil into the heating cycle at various points such that the temperature(s) needed for component extraction is optimal and yields a mixture of disinfecting agents (e.g. antimicrobial fatty acids, sterols, esters, terpenes, etc.) that combine to optimize the original oil's effectiveness as a source of disinfecting agents.

In some embodiments, at least one reaction zone is super-heated. In some embodiments, at least two reaction zones are super-heated. Super-heated reaction zones provide unique decomposition profiles and reactions. In some embodiments, the thermal profiles and dwell behaviors are differentiated. In some embodiments, when the reaction zone is super-heated, it is operated at a temperature in the range of from about 400° C. to about 1200° C., from about 600° C. to about 1000° C., from about 700° C. to about 900° C., or about 800° C.

In some embodiments, temperature, flow and/or dwell parameters are mapped to decomposition ranges and phases that are, in turn, mapped to specific disinfecting agents obtainable from a feed stock. In some embodiments, by choosing an appropriate feedstock, and matching it with appropriate phases, optimal disinfecting agents are produced in parallel and harvested, stored, and/or used as fumigants while pyrolyzation is performed.

In many embodiments, disinfecting agents produced according to the present disclosure are produced in parallel from the oil through any suitable means of production for such compounds. The means of production are configured for optimal production of multiple disinfecting agents from the oil.

In some embodiments, disinfecting agents are produced from the oil with a technique selected from the group consisting of pyrolytic decomposition, steam distillation, catalytic decomposition, and combinations thereof.

In some embodiments, the oil is in a reaction zone of the reactor for a dwell time suitable to produce at least one disinfecting agent. As used herein, dwell time is the time during which the oil is in a reaction zone of the reactor. Dwell times vary between disinfecting agents and the properties of the reactor, such as the gas flow rate, and are satisfactorily adjusted to optimize production of desired disinfecting agents.

In some embodiments, the dwell time is in the range of from about 0.01 seconds to about 2.5 seconds. In some embodiments, the dwell time is less than about 2 seconds.

Within this temperature range, numerous disinfecting agents become available while avoiding the production of excess solid particles, excess fine particles, and combustion.

In some embodiments, the gas is preheated via an external source prior to the method step of flowing a gas through a reactor. In some embodiments, one or more components of the reactor are temperature controlled. In some embodiments, the gas is preheated via an external source and then introduced, along with the atomized oil, into a reaction zone. In some embodiments, by preheating the gas and/or heating components of the reactor, natural cooling of the gas is mitigated and dwell times are better managed. Further, heating and preheating provide greater control over reactions, which is especially advantageous when multiple desired disinfecting agents require varying temperatures and dwell times.

In some embodiments, the control system comprises a means of control selected from the group consisting of an analog means of control, a digital means of control, and combinations thereof. In some embodiments, the control system is analog or digital. In some embodiments, the control system controls a reactor element selected from the group consisting of gas flow, power, oil feedstock, temperature, pressure, and combinations thereof.

Methods of Use

In many embodiments, disinfecting agents produced according to the present disclosure may be used according to any suitable means of use for such compounds.

In some embodiments, a method of using at least one disinfecting agent comprises: (i) producing the at least one disinfecting agent; and (ii) applying the at least one disinfecting agent to a target.

In some embodiments, the target is a surface comprising a living and/or infectious target.

In some embodiments, the applying the at least one disinfecting agent to a target comprises applying the at least one disinfecting agent to a target with a consumer product comprising the at least one disinfecting agent.

In some embodiments, the consumer product is selected from the group consisting of a wipe, a spray, a fumigant, a nebulizer, a vaporizer, mister, and combinations thereof.

EXAMPLES

Without further elaboration, it is believed that one skilled in the art using the preceding description can utilize the present disclosure to its fullest extent. The following Examples are, therefore, to be construed as merely illustrative, and not limiting of the disclosure in any way whatsoever.

Example 1

The reaction method comprises one or more method steps. Some of these steps include explicit or implied sub-steps. These steps and sub-steps are not intended to be limiting.

An oil is introduced as a spray or atomized mist into a heated gas (e.g. air) stream such that the temperature of the air thermally decomposes the oil given a sufficient dwell time. The dwell time is the time required to traverse a reaction zone, such as a heated or unheated open passage (e.g. a tube, tunnel, pipe, or hose), through which the air and oil mixture proceeds. The gas acts as a carrier for the oil. At one or more spatial intervals in the reaction zone, one or more condensers are optionally placed to collect certain disinfecting agents, such as constituent antimicrobial and sporicidal chemicals. These chemicals are optionally stored for subsequent use or allowed to be reintroduced into the gas stream as the heated air exits the reaction zone. In this manner, by adjusting temperature, dwell time, the number and location of injectors, and the number and location of condensers, individual species of chemicals or ranges of compounds are selectively produced from a single source.

Example 2

The reaction method comprises one or more method steps. Some of these steps include explicit or implied sub-steps. These steps and sub-steps are not intended to be limiting.

An oil which may be or contain a waste oil is optionally introduced into a reactor (e.g. an electrolysis chamber) to reduce glycerol content. The oil is then introduced as a spray or atomized mist into a heated gas (e.g. air) stream such that the temperature of the air thermally decomposes the oil given a sufficient dwell time. The dwell time is the time required to traverse a reaction zone, such as a heated or unheated open passage (e.g. a tube, tunnel, pipe, or hose), through which the air and oil mixture proceeds. The gas acts as a carrier for the oil. At one or more spatial intervals in the reaction zone, one or more condensers are optionally placed to collect certain disinfecting agents, such as constituent antimicrobial and sporicidal chemicals. These chemicals are optionally stored for subsequent use or allowed to be reintroduced into the gas stream as the heated air exits the reaction zone.

This written description uses examples to illustrate the present disclosure, including the best mode, and also to enable any person skilled in the art to practice the disclosure, including making and using any compositions or systems and performing any incorporated methods. The patentable scope of the disclosure is defined by the claims, and may include other examples that occur to those skilled in the art. Such other examples are intended to be within the scope of the claims if they have elements that do not differ from the literal language of the claims, or if they include equivalent elements with insubstantial differences from the literal language of the claims.

As used herein, the terms “comprises,” “comprising,” “includes,” “including,” “has,” “having,” “contains”, “containing,” “characterized by” or any other variation thereof, are intended to cover a non-exclusive inclusion, subject to any limitation explicitly indicated. For example, a composition, mixture, process or method that comprises a list of elements is not necessarily limited to only those elements but may include other elements not expressly listed or inherent to such composition, mixture, process or method.

The transitional phrase “consisting of” excludes any element, step, or ingredient not specified. If in the claim, such would close the claim to the inclusion of materials other than those recited except for impurities ordinarily associated therewith. When the phrase “consisting of” appears in a clause of the body of a claim, rather than immediately following the preamble, it limits only the element set forth in that clause; other elements are not excluded from the claim as a whole.

The transitional phrase “consisting essentially of” is used to define a composition or method that includes materials, steps, features, components, or elements, in addition to those literally disclosed, provided that these additional materials, steps, features, components, or elements do not materially affect the basic and novel characteristic(s) of the claimed disclosure. The term “consisting essentially of” occupies a middle ground between “comprising” and “consisting of”.

Where a disclosure or a portion thereof is defined with an open-ended term such as “comprising,” it should be readily understood that (unless otherwise stated) the description should be interpreted to also describe such a disclosure using the terms “consisting essentially of” or “consisting of”.

Further, unless expressly stated to the contrary, “or” refers to an inclusive or and not to an exclusive or. For example, a condition A or B is satisfied by any one of the following: A is true (or present) and B is false (or not present), A is false (or not present) and B is true (or present), and both A and B are true (or present).

Also, the indefinite articles “a” and “an” preceding an element or component of the disclosure are intended to be nonrestrictive regarding the number of instances (i.e. occurrences) of the element or component. Therefore “a” or “an” should be read to include one or at least one, and the singular word form of the element or component also includes the plural unless the number is obviously meant to be singular.
