Abstract
In order to select economical and reasonable Boil-off gas (BOG) treatment technology for different types of liquefied natural gas (LNG) stations, this
paper introduces the related technologies of BOG treatment without LNG Output. Using the same working fluid and operating parameters to simulate
then the six technologies of pulse tube cryocooler recovery, liquid nitrogen recovery, nitrogen expansion recovery, jet refrigeration recovery, mixed
refrigerant refrigeration recovery, and direct compression process were compared in terms of power consumption, economy. On the basis of
comparative analysis of power consumption, the actual usage of the above process, and with the payback period as the criterion, the BOG treatment
technology suitable for different types of LNG stations is obtained. It provides a reference for different types of LNG stations to select appropriate
BOG recovery technology, handles the unsolved problem about selecting BOG treatment technology, and puts forward a prospect for the
development of BOG treatment technology.
