As the sales volume of LNG products changes with the market situation, the output of LNG needs to adapt to the market changes. Therefore, high requirements are put forward for the elasticity of production load and LNG storage of LNG plants.
LNG production load regulation
Regulation of MR compressor
MR compressor is a centrifugal compressor. Its load can be continuously adjusted between 50 ~ 100% by adjusting the air inlet valve jacking device and return valve of the compressor.
Load regulation of pretreatment system
The design load of deacidification gas unit shall not be less than 100%. On the premise of controlling the pressure, the pretreatment system device can be continuously adjusted within the load range of 50 ~ 110% and meet the standard of pretreatment and purification.
Load regulation range of liquefied cold box
The design load of the liquefied cold box shall not be less than 100%. When the load of the device changes from 50% to 100%, the plate heat exchanger and valves in the cold box can work normally and fully meet the working conditions of variable load.
To sum up, the operating flexibility of the whole device is 50% ~ 100%. Users can adjust the load of the device within this range according to the sales situation of the product to improve the economy of operation.
Storage capacity adjustment of LNG storage tank
According to the LNG output, the storage tank volume we provide is the LNG output of ten days, and the storage volume of the storage tank can be used to buffer the sales change.
Liquefied natural gas (LNG), the main component of which is methane, is recognized as the cleanest fossil energy on earth. Colorless, tasteless, non-toxic and non corrosive, its volume is about 1 / 625 of the volume of the same amount of gaseous natural gas, and the mass of liquefied natural gas is only about 45% of the water in the same body.
The manufacturing process is to purify the natural gas produced in the gas field, and transport it by LNG ship after a series of ultra-low temperature liquefaction. The combustion of liquefied natural gas has very little air pollution and gives off a lot of heat, so liquefied natural gas is a relatively advanced energy.
