This invention avoids complexities involved in operation of existing methods, where heavy, expensive equipment and complex operation is prevalent. The invention is simple enough such that human error is effectively avoided.

After a nominal interval of time surface coating is removed from vehicle by normal washing, and reapplication of novel coating gives continuous, removal of pollutants. Waste wash water is disposed of as per normal processes, given pollutant is bound additive.

Continuous refilling of wind-screen wash with additive composition ensures continuous periodic removal of pollutants.

Additional cost of additive to existing technology should be minimal given the wide distribution and adoption of users of the technology.

DETAILED DESCRIPTION OF THE INVENTION

Ambient air pollutants are highly prevalent and are increasing with time. The invention claimed here solves, at least in part, this problem. A conventional automotive vehicle, defined as a vehicle propelled through time and space by motorized means, where addition of coating or wash comprising an active additive or additives that bond, absorb, adsorb or otherwise remove air pollutants under ambient conditions, that according to the invention, by adding from 0.1 to 99.9 percent by weight chosen from a list of chemicals well known to those skilled in the art. The active additive will coat vehicle and remain on vehicle upon completion of surface application, including simple wash/rinse.

Surface coating may be temporary or permanent. Permanent coating is designed to react with pollutant making pollutant benign and easily removed as pollutant bound, absorbed, adsorbed to active chemical component(s) product by simple washing.

Temporary coating is designed to capture, or react to provide benign reaction products with, pollutants. This improved surface wash, surface coating, windscreen wash, windscreen coating, is applied as a surface coating during regular periodic intervals. The active additive will coat vehicle and remain on vehicle until normal washing cycle is complete. Reapplication of surface coating gives continuous removal of pollutants.

Continuous refilling of windscreen wash with additive composition under normal operation conditions ensures continuous, periodic removal of pollutants.

The present claimed invention is an improvement on what currently exists. The approach currently in use to capture of air pollutants are only locally distributed and thus the amount of pollutant captured is limited. Further distribution of existing technology is prohibited by high cost. The present claimed invention spreads the cost among individuals, of whom will encounter only a small fractional increase in existing costs. Additional cost of additive to existing technology should be minimal given the wide distribution and adoption of users of the technology.

The scale of the current methods are small and only capture a very small fraction of air pollutants. This improved surface wash, surface coating, windscreen wash, windscreen coating, is applied as a surface coating, wash or treatment to automotive vehicles, during regular periodic intervals, wherein vehicle is washed, and surface coating applied and also applied as window wash as needed. And as such method is very well distributed geographically.

The present claimed invention avoids complexities involved in operation of existing methods, where heavy, expensive equipment and complex operation is prevalent. The invention is simple enough such that human error is effectively avoided.

After a nominal interval of time surface coating is removed from vehicle by normal washing, and reapplication of novel coating gives continuous, periodic removal of pollutants. Waste wash water is disposed of as per normal process, given pollutant is bound additive. The waste effluent provided by simple washing of, or application of, automotive vehicle surface coating, which contains active additive may be collected and used in further chemical treatment providing further air pollutant removal.

The present claimed invention is illustrated by the following example.

EXAMPLE 1

An Automotive Windshield Wash Formulation

Ethanolamine (HOCH₂CH₂NH₂) solution (10% by mass in methanol) was fed to top of a glass absorption column (1.55 m high, 0.092 m inside diameter) packed with 6 mm ceramic Raschig rings. The bed consisted of a 0.82 m long column. Gas flow of CO₂ was 20 L/min at 10% concentration in nitrogen fed to bottom of column; liquid flow rate for ethanolamine methanol solution was 1 L/min, fed to top of column. Detection of CO₂ at top of column showed drop in relative CO₂ concentration from 100 to 0.48. The reaction involved here is as follows:

HOCH₂CH₂NH₂ (Ethanolamine)+CO₂→HOCH₂CH₂NHCO₂⊖(stable carbamate)+HOCH₂CH₂NH₃⊕
