Help with Gas Compressors and Gas Compressor Systems specifications:

Compressor Technology

	Compressor Technology
	Your choices are...
	Axial		Multiple-blade rotor imparts axial velocity which is converted to pressure; very high flow rates.
	Blower		Dynamic head is imparted to the gas by means of high-speed impellers rotating in a confining case. Blowers are available in axial flow, radial, or centrifugal configurations.
	Centrifugal		High-speed impeller produces radial airflow; velocity converted to pressure energy.
	Diaphragm		Diaphragm oscillation driven by rod; no sliding seals or parts.
	Linear		Linear compressors have no sliding parts; compression is generated with electromagnetic oscillation. This type of compressor is clean and quiet.
	Reciprocating Piston		Piston mechanically reduces air volume inside cylinder.
	Rotary Lobe		Gas is moved by the positive displacement of two rotating lobes confined in an eccentric cylinder.
	Rotary Screw		Rotating, helical screw compresses air prior to discharge; provides even flow at relatively low pressures. Wet or dry screw types are utilized.
	Other		Other unlisted compressor configuration.

Lubrication Style

	Lubrication Style
	Your choices are...
	Oil-less		Permanently sealed bearings, low-friction compression components, and separation of process air from pump mechanics eliminate oil in air output. Oil-less is a term applied to compressors that contain no oil. Used for medical or more critical no-oil applications.
	Oil-free		An oil-free (dry) compressor will have no lubrication on the compression chamber side of the machine. This may not result in oil-free compressed air due to the fact that the ambient air being sucked into the compressor will contain hydrocarbons, which will condense into liquid oil further downstream.
	Lubricated		Compressor compression chamber and drive chamber are lubricated with oil. Lubrication can be done by a variety of means including splash, spray, or positive pressure.

Gases & Applications

	Gases:
	Your choices are...
	Air / Plant Air		Systems capable of providing compressed air for plant use, purified air for breathing applications, a combustion process, or for feeding a gas separation unit for the generation of nitrogen or oxygen.
	Ammonia		Ammonia or NH4 gas is used as a refrigerant gas or dissociated into hydrogen and nitrogen gases for metallurgical or chemical process applications.
	Argon		Argon is an inert gas that is heavier than air. The high density and inert nature allows argon to displace air which is important is shielding applications. Shielding or protective atmosphere gases prevent the oxidation or contamination of metal during welding or furnace processing.
	Corrosive / Sour Gas		Corrosive gases include sour gas, acid gas, halogen gases (chlorine or fluorine), and halide gases (hydrogen chloride, hydrogen fluoride). Sour gas is laden with traces of H2S.
	Carbon Dioxide (CO2)		Heavy gas consisting of a molecule of carbon and oxygen.
	Helium		Helium is an inert gas that is lighter than air.
	Hydrocarbon Gas		Acetylene, propane, ethane, methane, natural gas or other hydrocarbons available in a gaseous state at room temperature.
	Natural Gas / Methane		Natural gas is a gas mixture containing hydrocarbons with some impurities. It is comprised mostly of methane (CH4), an abundant organic compound readily used as a fuel and chemical feedstock.
	Nitrogen (N2)		Nitrogen gas (N2) makes up 78.1% of the Earth’s air, by volume.
	Oxygen (O2)		A gaseous element, oxygen forms 21% of the atmosphere by volume and is obtained by liquefaction and fractional distillation.  It is highly flammable.
	Propane		Propane is a heavy flammable gaseous alkane (C3H8) found in crude petroleum and natural gas, and used especially as fuel and in chemical synthesis.
	Refrigerant		Gases used in a refrigeration process such as ammonia, chlorofluorocarbon gases, R11 (CFC-11 or trichlorofluoromethane), R22 (HCFC-22 or chlorodifluoromethane),  R12 (CFC-12 or dichlorodifluoromethane), R502, R134a, R113, R123, R717, R500, R408A, R409A or R404A.
	Other		Other gas type not listed.

	Applications:
	Your choices are...
	Gas Boosting		Gas boosting is the increase of pressure in a system, such as the introduction of a gas, to induce or maintain flow of a liquid in a storage tank, tank cars, or vessel. This is done to maintain the pressure in system to prevent an influx of contaminants or to maintain a fuel gas at a pressure suitable for combustion in a gas turbine. Gas boosting is also used to increase the pressure of gas gathered from the wellhead to transmission pressure levels.
	Gas Transmission / Delivery		Systems used to move or pump gas through gas transmission pipelines or plant delivery lines.
	Fuel Gas / Power Generation		Unit or system suitable for fuel gas compression in gas turbine applications. The compressor system increases the pressure of the fuel gas, such as waste or landfill gas, to a level suitable for efficient combustion in a gas turbine or other combustion engine.
	Gas Generation / PSA		Systems used in gas separation, generation, or purification operations to produce oxygen, nitrogen, or other gases from a compressed air or other feed. For example, systems for processing tail or feed gas from the molecular sieve portion of pressure or vacuum swing adsorption (VSA) unit.
	Oil Refining / Chemical Processing		Cracking, distillation, hydrotreating, and other refining processes require gases to convert crude oil into gasoline, fuel oil, and petroleum byproducts. Compressor systems supply front-end, recycled, and make-up gases for oil refining equipment.
	Oil / Vapor Recovery		Systems used to improve recovered oil or vapor from a well or field site. Environmental regulations may restrict the flaring or venting of byproduct vapors at the oil well. Gas injection or lifting utilizes the injection of compressed gas to the wellhead to aerate or displace the produced fluids, reducing the pressure at the bottom of the well bore and increasing or sustaining the well's flow rate.
	Process Gas Feeding / Injection		Chemical, metallurgical, or other process gas applications, such as feeding gas into or out of a reactor or furnace. Hydrogen, carbon dioxide, nitrogen, hydrocarbons, or other gases are commonly fed into a reactor or process unit for: Hydrogenation Protective blanketing Injection or sparging of a gas into a liquid to remove contaminants or dissolve a gas  Recovery of solvents Polymerization or to initiate other chemical reactions
	Refrigeration / Gas Drying		Gas plant glycol dehydration, gas chiller, and refrigeration skids are examples of refrigeration packages for industrial plants.
	Vessel / Cylinder Filling		Gas compressor systems designed for filling vessels, cylinders, or bottles with high-pressure gas.
	Other		Other application not listed.
