Main Process Packages for Flare Gas Recovery Unit

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.

Mini and Small-Scale LNG (MSLNG & SSLNG) plant is the use of small liquefaction and regasification facilities that enable flexible supply chains to deliver to multiple smaller distributed users. These users would normally consume energy with short supply agreements, at lower quantities or in remote locations that would previously be unserved by conventional natural gas infrastructure.
Greenfir has years of valuable experience in developing liquefaction technology for small scale applications. We understand the importance of operational simplicity, flexibility, efficiency, equipment robustness, and a compact footprint when dealing with mini and small scale LNG projects.
Advancing technology is making even smaller units feasible and opening up new markets. LNG can be transported by road or train to be delivered into skid-mounted storage at the point of use, providing flexible and deployable energy at significantly reduced costs to the user.

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.

• Filtering & Metering Skid
• Gas Purification System (Acid Gas Removal package, Dehydration Package, and Mercury Removal Package)
• Liquefaction (Cold Box, MR Compressor, etc.)
• LNG Storage
• LNG Loading System
• Utilities (Instrument Air & PSA Nitrogen Generattion Package, Demineralized Water System, Hot Transfer Oil System)
• Instrumentation Control System
• Electrical Control System
• Feed Gas Booster Compressor(s) (Optional)
• Nitrogen Removal Column (Optional)
• Heavy Hydrocarbons Separation (Optional)
• Biol-off Gas Handling (BOG Compressor) (Optional)
• Power Generation (Optional)
• etc.
