| titleOfInvention | A kind of liquefied method and device of twin-stage swell refrigeration high methane gas |
| abstract | The invention discloses a kind of liquefied method and devices of twin-stage swell refrigeration high methane gas, belong to high methane gas separation and liquefaction field, purpose is to solve the production method of existing liquefied natural gas, and there are heavy hydrocarbon separation is difficult, it is cumbersome, equipment investment is higher, methane losses are larger, the higher problem of energy consumption.This method includes high methane gas liquefaction, circularly cooling step, after methane rich unstripped gas is mixed with pre- hot gas, through heat exchanger cooling, reducing pressure by regulating flow, gas-liquid separation, respectively obtain liquefying high methane gas, low-flash gas, liquefying high methane gas is collected as product, and low-flash gas then carries out open loop refrigeration or closed cycle.The advantages that present invention has process simple, and low energy consumption, and flexible operation, equipment investment is low, and methane losses are small, and nitrogen separation works well, and heavy hydrocarbon easily removes. |
