AI Technical Summary
In the prior art, the NBOG cooling system at the inlet of the compression unit of liquefied natural gas carriers leads to an increase in the amount of NBOG generated in the tank, affecting the ship's energy balance and operating evaporation rate.
The operation of the pumping components is controlled by the monitoring unit. Liquid gas is used to spray cooling vapor gas. The state of the pumping components is adjusted according to the temperature and other parameters at the inlet of the compression unit to reduce unnecessary liquid gas flow and optimize the cooling effect.
It effectively reduced the gas temperature at the inlet of the compression unit, reduced the generation of NBOG, and optimized the ship's energy balance and operating evaporation rate.
