Abstract

The invention relates to a process for depressurizing a gas G1 from a pressure P1 to pressure P2, said gas G1 comprising freezable species and being contained in a capacity (6), said process comprising the following steps: 1) Providing said capacity (6) with a depressurization system which can be fed with said gas G1, said depressurization system comprising in the direction of flow a first automatic valve (1) in closed position, a line (2) comprising a gas G2 free of freezable species at a pressure P1 a second automatic valve (3) in closed position, and a restriction orifice (4), 2) Opening the first automatic valve (1) so that gas G1 and G2 come into contact at pressure P1, 3) Opening the second automatic valve (3) so that gas G1 and G2 flow through the restriction orifice (4) thereby recovering the gas G1 whose pressure is lowered to a pressure P2. The invention also relates to the depressurization system for implementing the process of the invention. Figure 2
