TODAY’S PATENT – A TREATMENT SYSTEM OF LIQUEFIED GAS

The invention is focused on a system for processing liquefied gas, such as liquefied natural gas (LNG) and liquefied petroleum gas (LPG), which are increasingly being used as an alternative to gasoline and diesel. The aim of the liquefied gas treatment system is to reduce fuel waste by preventing evaporative gas from being discarded, and to enhance driving efficiency by utilizing flash gas mixed with the evaporative gas.

The invention was patented by the Korean Intellectual Property Office on 29th July 2013, bearing the serial number KR101289212B1. The system works by pressurizing the evaporated gas produced in the liquefied gas storage tank through external heat penetration, and supplying it to the liquefied gas demand. Alternatively, the flash gas can be circulated with the evaporative gas compressor to pressurize the evaporated gas, which can then be liquefied. By supplying the evaporative gas to the gas demand instead of discarding it, the system saves fuel. Mixing the flash gas with the evaporative gas ensures that a certain flow rate or more is supplied to the evaporative gas compressor, which minimizes recycling control.
