Product Description
Greenfir is a professional natural gas processing & liquefaction plant, air separation unit, heat exchanger, reciprocating piston compressor, cryogenic cold box, fractionating column manufacturer and solutions provider with ISO 9001: 2015, ISO 14001: 2015, ISO 45001: 2018 and ASME U certified.
We offer skid-mounted solutions optimized for each specific project, covering the following applications: Air Separation Plant, LNG Plant, Gas Purification & Liquefaction Unit, CNG/ LNG/ L-CNG Filling Station, Flare Gas Recovery Unit and Hydrogen Purification Unit, etc. We can deliver skid-mounted solutions customized to meet client's challenges and requirements (including adverse weather conditions, transportation and plot area limitations, etc).
We treat all the cryogenic solutions with serious attitudes and professional experience. Combined with our knowledge and experience, Greenfir provides each client with a technology-leading solution you can count on and bring a wider range of options and more profits.
Greenfir provides solutions for your gas processing project, including shop fabrication, construction management, startup, and operations. We offer a range of solutions to best meet your gas processing needs - from straightforward dew pointing operations, to maximum NGL recovery.
Modular Design for Reduced Costs and Predictable Timelines
Our modular gas processing plants are factory-built using a unique design and construction approach that allows for quick fabrication and superior quality control. Due to pre-fabricated construction, your plant can be shipped by truck - even to remote locations. Upon delivery to a prepared worksite, the equipment is ready to install. Modules are designed to fit together rapidly, significantly reducing site construction time, expense and associated delays.
Greenfir liquefaction technologies are mostly based on the MR (mixed refrigerant) technology. It is designed with a closed loop refrigerant cycle, thereby eliminating make-up or chemical/ logistics handling for the refrigerant. The main elements of the plant are as listed below, while different modules can be incorporated to improve the efficiency of the plant according to the specific project requirements.

Our extensive service offerings, coupled with our unmatched technical knowledge and experience, can help you focus on profitability.
The first step in natural gas processing is to separate the raw natural gas from the water and condensate. Second, the contaminants, which include hydrogen sulphide (H2S), carbon dioxide (CO2), mercaptans, carbonyl sulphide (COS) and mercury, must be removed.
