The present disclosure generally pertains to industrial plants, and is more particularly directed toward a modular construction and deployment of an industrial plant housing turbo machinery.
Industrial plants housing turbomachinery, such as natural gas compression plants, or oil pumping stations, transport hydrocarbons from one location to another location. Industrial plants housing turbomachinery may also generate electricity. Such industrial plants are frequently constructed in remote locations. Construction of these plants may require a substantial amount of labor and time, especially in certain regions of the world. Modular construction and deployment of a plant can reduce startup delays, save on labor costs, and ensure optimum operability.

Other equipment and components may be shipped to and assembled at a designated site.
The gas compression plant 100 may include a plurality of substructures (105, 110) and components. Each substructure (105, 110) may be formed from a plurality of linear members 120, 125, 130 arrange to form rigid frames to support sealing panels, which may be noise or sound attenuating panels in some example implementations. For ease of illustration, the sealing panels have been omitted in
The substructures (105, 110) can be arranged and stacked in numerous configurations, which allows flexibility to scale the gas compression facility with the size of the equipment and to allow Balance of Plant (BOP) scope. Some of the substructures (105, 110) may incorporate turbomachinery support systems such as fuel gas treatment, seal gas treatment, compressor piping, unit and surge valves as required, utility air compressors, backup generator, electrical equipment, as well as all utility distribution systems for air, lube oil, vents, and drains.

The substructures (105, 110) may be configured for installation on a concrete foundation, or, on pilings using a skidded sub-base.
As illustrated, the substructures (105,110) may be stacked in two or more levels and Additionally, a series of roof support trusses 115 may be mounted on the substructures (105, 110) to support a roof over the compression plant 100.
To ensure alignment and to re-enforce gas compression facility 100, connections 145-155 between the substructures (105, 110) may be formed at different locations within the gas compression facility 100. For example, connection 145 may be at locations within the gas compression facility 100 where the corners of four substructures 105 meet. Further, connection 150 may be used at locations within the gas compression facility 100 where corners of only two substructures 105 meet, such as building corners. Additionally, connection 155 may be used at locations within the gas compression facility 100 to connect an end of one substructure 110 to a region of another substructure 105 located separate from the end. The connections 145-155 are discussed in greater detail below with respect
In some example implementations, the largest size of any substructure (105, 110) may be patterned after the International Organization for Standardization (ISO) freight container standards, but may not meet ISO required dimensions. For example, the width of each substructure (105,110) might be is limited to 2.28 m (7 Ft., 6 in.), so that after application of acoustic sealing wall panels the ISO container width of 2.4 m (8 Ft.) is not exceeded. Additionally, the height might be limited to 4.1 m (13 Ft., 6 in.).
In some example implementations, the substructures (105, 110) may have different lengths. For example, each substructure 105 may have a length of 13.7 m (45 Ft.), a width of 2.28 m (7 Ft., 6 in.), and a height of 4.1 m (13 Ft., 6 in.). Alternatively, substructure 110 may be shorter than substructure 105 and have a length of 6.1 m (20 Ft.), a width of 2.28 m (7 Ft., 6 in.), and a height of 4.1 m (13 Ft., 6 in.). Example implementations of the substructures (105, 110) may have other dimensions as may be apparent to a person of ordinary skill in the art.
The difference in length between the substructure 105 and the substructure 110 may be used to form an access opening 175 to gas compression plant 100 by placing the shorter substructure 110 below the longer substructure 105. The opening 175 may be formed at the end of shorter substructure 110 as illustrated.
The connector 205 also includes fasteners 215 inserted through the connector receiving point 170 of one substructure 105, the spacer plate 210, and the connector receiving point 170 of an adjacent substructure 105.

Additionally, at the connector receiving point 170, a window 225 may be formed in each vertical member 120 to assist with installation and placement of the fastener 215, and nuts 220.
At the connection 155, the connector 805 connects the connector receiving points 170 of the two substructures 105 and the connector receiving points 177 of the other two substructures 105 together. The connector 805 includes a spacer plate 810 installed between the connector receiving points 170 of the two substructures 105 and the connector receiving points 177 of the other two substructures 105. The spacer plate 810 is discussed in greater detail below with respect to
The connector 805 also includes fasteners 215 inserted through the connector receiving point 170 of one substructure 105, the spacer plate 810, and the connector receiving point 170 of the adjacent substructure 105. In some example implementations, the fastener 215 may be a bolt or threaded shaft that is held in place by a nut 220 at one or both ends.

The sealing panels 1705, 1710, 1715, 1720 of the temporary workspace module 1700 can be lined with sound attenuation material.
The standing desk 1730, paper/record storage such as bookcases 1735 and file cabinets 1740 may be installed in the temporary workspace module 1700 prior to shipment a job site. Power cables and piping connecting temporary workspace module 1700 to the remainder of the gas compression plant 100 (shown in
The piping and cable distribution module 1800 may include auxiliary systems for the compressor train such as lube oil separating equipment 1825. These systems may require pipe and cable to be routed through the substructure 105. Building systems such as glycol heating also require piping to be routed through the substructure 105. The modules, such as the piping and cable distribution module 1800 that make up the gas compression plant (shown in
The Seal Gas Treatment Module 1900 may be used to coalesce liquids and filter the gas, and raise the temperature to at least 50F above the hydrocarbon dew point, before it is delivered to a compressor skid. Additionally, the Seal Gas Treatment Module 1900 may be used whenever the available seal gas has components that could condense in the dry gas seals, or particles above the limits stated in performance standards for equipment used in the gas compression plant 100 (shown in
Like the piping and cable distribution module 1800, the Seal Gas Treatment Module 1900 may include pipe 1905 and/or cable routed through the substructure 105. The Seal Gas Treatment Module 1900 may also include seal gas treatment equipment 1910 integrated within the substructure 105. The seal gas treatment equipment 1910 may include: a coalescing filter, an electric heater; and any necessary valves, drain and venting piping.
For example, a dual coalescing filter stage may be used to separate the liquid/solid phase/particles from the gaseous phase inside the gas stream. The coalescing filter stage may be designed for automatic draining of the liquid phase. The coalescing filter stage may include continuous pressure differential monitoring and pressure safety valves will be provided to protect the equipment from over pressurization.
Additionally, a single electric gas heater may increase and control the temperature of the gas in order to avoid condensation inside the dry gas seals. The heater and its control may be designed to follow all normal and emergency operating conditions during GT operation. A pressure safety valve may be provided with the gas heater to protect the equipment from over pressurization. Additionally, a heater bypass may be included to allow for short term continued operation during heater maintenance.

For example, a horizontal coalescing filter 2035 may be used to allow the vessel to be the smallest diameter, and placed flat against the sealing panel 2020 of the Fuel Gas Treatment Module 2000. Additionally, filter replacement may be easier if horizontal, rather than the vertical as in certain instances the substructure 105 height may limits vertical filter replacement headroom. Alternatively, vertical filter replacement may require overhead tackle or access.
In some example implementations, the coalescing filter 2035 may be a dual coalescing filter stage that may separate the liquid/solid phase/particles from the gaseous phase inside the gas stream. The coalescing filter 2035 will be designed for automatic draining of the liquid phase. The coalescing filter 2035 may be provided with continuous pressure differential monitoring. Further, pressure safety valves will be provided to protect the coalescing filter 2035 from over pressurization.
Further, the electric heater 2040 may also be horizontal as this allows for easy bundle replacement in some example implementations. In other example implementations, vertical placement may be used if bundle replacement is made possible. In some example implementations, electric heater 2040 may be by-passable to allow for short term continued operation during heater maintenance. The electric gas heater 2040 may increase and control the temperature of the gas in order to avoid condensation inside the fuel gas lines up to the injector nozzle based on equipment standard and gas line design temperature requirements. The electric gas heater 2040 and its control may be designed to follow all normal and emergency operating conditions during Gas turbine operation. In some example implementations, a pressure safety valve may be provided to protect the equipment from over pressurization.
Additionally, a glycol heat exchanger with bypass control may be incorporated in place of the electric heater. The glycol heat exchanger might have a pipe in pipe configuration, or may have a shell and tube configuration depending on the heater size.
The electrical equipment 2130 and battery systems associated with the compression equipment and BOP may be located in the local equipment room module 2100. When the local equipment room module 2100 is incorporated into the gas compression plant 100 as illustrated, the local equipment room module 2100 may be fabricated to be air-tight and have a pressurization system to guarantee no ingress of flammable gases.

The Warehousing Module 2300 may provide storage space for spare parts storage, tools and calibration equipment, or other supplies that the plant operator at the gas compression plant 100. A single, full Warehousing Module 2300 may provide approximately 360 sq. ft. of floor space, and the walls can be furnished with shelves or cabinets 2330.

Though a variety of modules have been described relating to the operation of a gas compression plant, example implementations are not limited to a gas compression plant and may alternatively include other types of facilities that might be apparent to a person of ordinary skill in the art. For example, other implementations might include a natural gas burning power generation facility for generating electricity, a pumping station for delivering oil or gasoline through a pipeline, or any other facility that might be apparent to a person of ordinary skill in the art. Similar modules may be used and customized to the intended operation of the building constructed.
Plants for operating turbomachinery equipment have a variety of uses. Such buildings might include a gas compression plant for delivering natural gas through a pipeline, a natural gas burning power generation facility for generating electricity, a pumping station for delivering oil or gasoline through a pipeline, or any other facility that might be apparent to a person of ordinary skill in the art. These plants may be in very remote locations. For example, gas compression plants may be used for transporting fuel from natural gas deposits through a pipeline. Frequently, natural gas deposits are located in remote areas of the planet.
Constructing and deploying a gas compression plant or other turbomachinery equipment plant at such a remote area may be difficult and expensive. For instance, transporting individual panels, pipes, and other construction materials may require a large amount of delivery trucks. Assembly of the gas compression plant or other turbo machinery equipment from the individual construction materials may take a substantial amount of manpower and time. Additionally, laborers may have to travel to the remote area and sleep in special lodging facilities just to build and test the gas compression plant. These factors may lengthen the construction time for a remotely located gas compression plant.
Using a modular construction system made up of substructures or modules such as those illustrated in the above discussed embodiments of the invention may yield significant advantages. For example, constructing an operations building that houses turbomachinery equipment in separate substructures can allow for efficient delivery and deployment. Each of the substructures is fabricated in sizes largely similar to ISO containers, which may reduce transportation costs. Other large structures such as a gas processing structure may also be constructed of individual substructures. By constructing the substructures at a fabrication facility, laborers do not need to travel and stay extended periods of time at the remotely located site in order to construct the gas compression plant. All substructures may be standardized and customizable depending on the size of the gas compression plant and/or the size of the turbomachinery equipment. This can save on equipment and construction costs.
Large structures such as the operations building may be placed on a variety of different foundations. For example, the operations building may be placed on a concrete slab. In other instances, the operations building may be placed on a plurality of pilings. The pilings may be tubular members composed of metal or wood. The pilings may be installed in the ground and extend a certain height upwards from the ground. The plurality of pilings may generally be positioned in a rectangular grid like format. In certain instances, the plurality of pilings may allow greater vibrational forces to resonate through the operations building caused by the turbomachinery equipment.
In addition, all components of the modular gas compression plant may be tested at the fabrication facility for functional operation. This can save time later where problems that may occur during initial testing of the fully assembled turbomachinery plant at the remote location are instead found at the fabrication facility. All substructures and components of the modular turbomachinery plant may be efficiently delivered to the remote site, deployed quickly, and seamlessly integrated together.
Further, the substructures 105/110 or modules of the building construction system may include connection receiving points 170 that receive specifically designed connectors 205/605/805 located at corners and along edges of the substructures 105/110 to allow more efficient alignment of the substructures with respect to each other. These connection receiving points 170 may include windows 225 within the vertical and horizontal support members 120 to allow insertion of fasteners 215 through connection receiving points 170 after substructures 105/110 have been placed onsite. The structure of the connectors 205/605/805 may include one or more spacer plates 210/610/810 inserted between adjacent substructures 105/110 to reinforce and support the connections between adjacent substructures 105/110.
Additionally, the strength of the connectors 205/605/805 may be sufficient in some example implementations to allow stacking of the substructures 105/110 in two or more levels and the mounting of a bridge crane from upper levels of the stacked substructures.
