  About UsGreenfir 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.Product DescriptionMini 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.Process TechnologyGreenfir 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.Main SystemFiltering & Metering SkidGas Purification System (Acid Gas Removal package, Dehydration Package, and Mercury Removal Package)Liquefaction (Cold Box, MR Compressor, etc.)LNG StorageLNG Loading SystemUtilities (Instrument Air & PSA Nitrogen Generattion Package, Demineralized Water System, Hot Transfer Oil System)Instrumentation Control System Electrical Control SystemFeed Gas Booster Compressor(s) (Optional)Nitrogen Removal Column (Optional)Heavy Hydrocarbons Separation (Optional)Biol-off Gas Handling (BOG Compressor) (Optional)Power Generation (Optional)etc.Customer Benefits-  Robust and reliable technology that is simple to operate.-  Designed for unmanned operation.-  Easy start-up and shut down of all systems.-  Quick and easy capacity control.-  Compact and modularized design ensures easy shipment and cheaper installation.-  The lowest specific power consumption in small size plants.-  All components based on conventional parts and proven technology -> Spares can be delivered quickly.-  Reliable main rotating machinery with high efficiency.-  Local control of LNG export -> truck driver handles the loading.-  Fast project delivery time (FOB 7 months for the MRC Process).-  Broad range of applications, biogas, pipeline, CBM and associated gasReference ListProjectScope of SupplyCapacityQuantityLocationYearNatural Gas Purification, Liquefaction Plant50,000 Nm3/day Wellhead Gas Recovery ProjectEPC 1ChinaNov. 201630,000 Nm3/day Mini LNG PlantEPC 2ChinaMay, 201730,000 Nm3/day Wellhead Gas Recovery ProjectEPC 1ChinaMay, 201730,000 Nm3/day Mini LNG PlantEPC 1ChinaNov. 201850,000 Nm3/day Wellhead Gas Recovery ProjectEPC 1ChinaNov. 201960,000 Nm3/day Mini LNG PlantEPC 1ChinaNov. 2018Demethanizer and Deethanizer Rectification SystemEP20,000 Nm3/day KazakhstanJul. 2020CNPC 100,000 Nm3/h Mini LNG PlantEPC 2ChinaJan. 2021ARV 50 TPD Mini LNG Plant ProjectEP, Supervision Commissioning & Start-up50 TPD1IrianApr. 2021MAN 3.5 MMSCFD Mini LNG Plant ProjectEP, Supervision Commissioning & Start-up3.5 MMSCFD1IrianApr. 202150,000 Nm3/day Mini LNG PlantEPC 1ChinaAug. 2021Ethylene Compressor StationEP, Supervision Commissioning & Start-up17.88 MMSCFD IrianApr. 2022MAR 20 MMSCFD Amine Sweetening Package ProjectEP, Supervision Commissioning & Start-up20 MMSCFD1IrianDec. 2022KHE 13 MMSCFD Field Flare Gas Recovery ProjectEP, Supervision Commissioning & Start-up13 MMSCFD1IrianDec. 2022100,000 Nm3/h Mini LNG PlantEPC 2ChinaDec 2022Deethanizer Rectification SystemEP30,000 Nm3/day1KazakhstanMar. 2023  /* January 22, 2024 19:08:37 */!function(){function s(
