APPARATUS AND METHOD FOR REGASIFICATING LIQUEFIED HYDROCARBON GAS

摘要

A device and a method for re-evaporating the hydrocarbon liquid gas are provided to easily control the calorific value by controlling the discrete quantity of the LPG component according to the calorific value required in the demand side. A device for re-evaporating the hydrocarbon liquid gas comprises a hydrocarbon separation unit and a heating unit. The hydrocarbon separation unit uses the evaporation temperature difference between the low circumflex hydrocarbon component and the high caloric hydrocarbon component. The hydrocarbon separation unit separates the high caloric hydrocarbon component and low circumflex hydrocarbon component. The heating unit heats up the hydrocarbon liquid gas to be supplied to the hydrocarbon separation unit. The heating unit is made one of a heater(23) and a heat exchanger(22). The hydrocarbon separation unit comprises a vapor-liquid separator. The vapor-liquid separator separates the liquid with the high caloric hydrocarbon component and vapor with the low caloric hydrocarbon component.
