Product DescriptionThe current global quest for utilizing cleaner energy while remaining cost competitive has fueled the rising demand for more flexible natural gas supply methods such as Compressed Natural Gas (CNG) and Liquefied Natural Gas (LNG). Natural Gas is commonly distributed in gaseous form to end users via a network of pipelines and is a very low-cost source of energy; however, the challenge experienced by small end users is that access requires sufficient capital, long term supply agreements or access to existing natural gas pipeline infrastructure.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.Process Technology

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.

Main System

• 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.
