LNG Production Unit

Primarily using methane-rich exhausted gas to obtain LNG, and the common processes are mixed refrigerant cycle (MRC), pre-cooling, nitrogen cycle expansion, etc. Kaiyuan has successively put into operation several cryogenic separation liquefied LNG plants, in which the Qianan Yichi liquefied natural gas plant was the largest coke oven gas LNG plant in China at that time.

Product Description

Primarily using methane-rich exhausted gas to obtain LNG, and the common processes are mixed refrigerant cycle (MRC), pre-cooling, nitrogen cycle expansion, etc. Kaiyuan has successively put into operation several cryogenic separation liquefied LNG plants, in which the Qianan Yichi liquefied natural gas plant was the largest coke oven gas LNG plant in China at that time. It produces 1 million cubic meters of liquefied natural gas per day, and the methane recovery rate is as high as 99.5%.

Advantages:

1. The patented technology is mature and the process is optimized.

2. The operation is stable and simple.

3. low operating energy consumption.

4. high product purity and high hydrogen recovery rate.

5. Excellent pre- and after-sales services.
