Regasification in the oil & gas industry
Converting LNG to natural gas
At the receiving terminal the LNG is stored within very large and extremely well insulated tanks. Custody transfer measurement systems on the delivered LNG and the boil off gas returned to the ship’s tanks to provide accurate accounting data on the received fuel into the terminal. Once the tanker has left, any boil off gas is compressed and re-liquefied in a condenser, or alternatively can be flared off, via a flowmeter.
