small scale LNG Liquefaction Plant

LNG Liquefaction Plant is an equipment to produce liquefied natural gas, which is a kind of liquid natural gas that has been pretreated and liquefied at a low temperature. Compared with conventional natural gas, it has a higher heating value and cleanliness, which is convenient for storage and transportation. In the development of the natural gas industry, liquefied natural gas will be an important part of it and an important supplement to pipeline natural gas.

Products Details

LNG Liquefaction Plant is an equipment to produce liquefied natural gas, which is a kind of liquid natural gas that has been pretreated and liquefied at a low temperature. Compared with conventional natural gas, it has a higher heating value and cleanliness, which is convenient for storage and transportation. In the development of the natural gas industry, liquefied natural gas will be an important part of it and an important supplement to pipeline natural gas.

The small and medium-sized natural gas liquefaction plant adopts the international advanced SMRC refrigeration process, which has the characteristics of simple process, low energy consumption, strong adaptability to changes in gas source components, small footprint, and low equipment costs.   The main markets and uses of small natural gas liquefaction plants for LNG products: It mainly supplies end users outside the natural gas pipeline network, gasification stations, gas filling stations, and downstream portal stations. 1. Industrial fuel, used for self-contained power generation, ceramics, glass bulbs, process glass, etc. to replace coal-fired fuel; 2. Clean fuel, use after gasfication station vaporization, for pipeline gas service in buildings, communities, small and medium towns; 3. Automobile fuel, delivered to the gas station, can provide LNG and CNG gas source refueling services;  

System composition

 

The process and control components of the skid mounted LNG Plant include process system, control system and utilities. Here we take mini LNG Plant (small scale LNG plant) for example.
