The present invention provides a device for controlling steam explosion of biomass having a dry solids content above 1%, a VS content of above 20%, and including abrasive material, in a pressure relief vessel, which includes one or more blowdown conduits having at their outlets an adjustable open area for regulating the blowdown discharge rate. The adjustable open area of each of the one or more blowdown conduits are constructed in such a way that expansion/spray due to flashing takes place either inside the pressure relief vessel itself or in an additional inlet device through which the discharged biomass is directed from the adjustable open area and into the pressure relief vessel and which either have a large enough dimension to avoid the discharged biomass hitting essential parts of the construction or is made from a highly resistant/durable material.

Device for controlling thermal hydrolysis decompression and process plant comprising such device

A method and plant for hydrolysis of a liquid substrate, having a dry solids content of between 2 and 30%, to be used in an anaerobic fermentation, digestion or another process aimed at producing or extracting methane or other valuable substances, which method and plant relies on the use of vacuum and several pulpers and one or several flashtanks in series for step-wise pre-heating and pressure reduction, respectively.
