A protection system arranged to prevent a large trans-membrane pressure difference over a pressure sensitive membrane (4) fitted in a pressure resistant chamber (3), wherein the membrane forms a physical barrier between a liquid and a gas mixture carried through the chamber (3), the protection system includes two shut-off valves (9, 10) provided in the liquid inlet and outlet lines respectively, a buffer tank (3) provided in the line between one of the shut-off valves (9, 10) and the pressure resistant chamber (3), a pressure equalizing valve (12) provided between the gas inlet line (8) and the buffer tank (2) and a pressure sensing valve (14) for measuring the pressure difference over the membrane (4) and which activates the shut-off valves (9, 10) once this pressure difference exceeds a predetermined value.
A protection system arranged to prevent a large trans-membrane pressure difference over a pressure sensitive membrane fitted in a pressure resistant chamber having respective inlet and outlet lines for a gas and a liquid, where the membrane forms a physical barrier between a liquid and a gas once a liquid and a gas mixture are carried through the chamber, characterized in that the protection system comprises:
