An apparatus for feeding a combustible gas to a gas consuming member and liquefying the combustible gas

摘要

The present invention relates to a facility (1) for feeding a combustible gas to a gas consuming member (2, 3, 4) and liquefying the combustible gas, the facility comprising: - sealing and adiabatic tanks (5a, 5b, 5c, 5d) ; - a vapor phase gas collection circuit (6) for withdrawing a combustible gas stream from the tanks (5a, 5b, 5c, 5d); - a heat exchanger (8) comprising a first channel (9) connected to a steam phase gas collection circuit (6); A first channel 9 of the heat exchanger 8 for delivering the combustible gas to the gas consuming members 2 and 3 and 4 and returning the combustible gas to the second channel 10 of the heat exchanger 8; A compressor (11) connected to a three-way connector (12, 13) which can be operated; An expansion device (14) connected to the second channel (10) through a heat exchanger (8) via an intermediate circuit (15); A liquid phase flammable gas stream withdrawn from the tank and a vapor phase combustible gas stream circulating in the steam phase gas collection circuit 6 and a second portion of the combustible gas stream circulating in the intermediate circuit 15, And a cooling device (16) arranged to transfer heat between the cooling device (16).
