The LNG storage tank has a capacity of 150 m3; the temperature of the LNG exiting the cryogenic tank is -160 degrees Celsius, while the temperature in the LNG storage tank ranges from -156 to -158°C. After being pumped out via submersible pumps and loaded onto the loading arm, the temperature rises to -151°C. The tank pressure is 0.16 MPa. Please provide some suggestions for troubleshooting. Thank you
1. Check whether there are any abnormalities with the submersible pump. If the pump’s efficiency is low, it may cause LNG to heat up. 2. Check the insulation of the pipelines and loading arms. Poor insulation can cause the LNG to heat up during transportation. 3. Check whether the storage tank has good thermal insulation properties, and verify if there is any damage to the tank or a decline in its insulating capacity. 4. Check whether any external heat source is affecting the temperature of the LNG. 5. Evaluate the effect of pressure changes on temperature to confirm that the system operates properly within the designed pressure and temperature ranges. .
