摘要:
A retention system is described for collecting substances from installations. This includes at least one outlet line which opens into at least one flexible container which is joined in am essentially pressure-tight manner. The container is attached to a pressure relief valve and serves as a pressure relief safety device for conducting away substances from the installation. The flexible container must be dimensioned at least so that in the filled state it has an internal volume such that the internal pressure of the joint system of outlet line and flexible container virtually corresponds to the external pressure.
