The project researched and tested the method and extent of residual gas (liquid) recovery during regular inspections of LNG tankers in use. By comparing existing recovery technologies and research tests, a set of practical and reliable natural gas residual gas ( The recovery and treatment system of liquid) can be used for the recovery of residual gas (liquid) of the LNG tanker as a cryogenic container, which further improves the recovery and purity of natural gas (liquid).

The project developed and installed 1 set of recovery device system, which has been put into use in the tank truck inspection center of our hospital, and the effect has reached the expected goal.
