Estimating the term…
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.
A safety retention system comprising a reaction vessel in which chemical reactions are carried out and which contains various substances, the vessel having at least one outlet, a pressure-relief safety device connected to the outlet constructed and arranged to open the outlet to relieve unexpected pressure or a blow out in the reaction vessel, at least one flexible container for receiving unexpected pressure buildup and various substances from the reaction vessel when the pressure-relief safety device opens the outlet of the reaction vessel, an outlet line extending between the pressure-relief safety device and the at least one flexible container, and wherein the at least one flexible container is composed of high strength fabric and the at least one flexible container has a volume dimensioned to receive escaping substances from the reaction vessel via the pressure-relief safety device and the outlet line whereby an internal pressure buildup in the at least one flexible container is no more than 3 bars above external pressure.
