An apparatus, for the steam explosion treatment of biomass, having a pressurized reactor vessel to receive a biomass material and steam, discharge lines connecting the pressurized reactor vessel to the separation device, the lines sized and positioned to allow for the steam explosion of biomass material. At the outlet end of the discharge lines is a collection-expansion manifold to connect the outlet end of each of the discharge lines to a collection line, wherein the collection line provides a passage for biomass material and steam flowing from the discharge lines. The collection line passage has a substantially larger cross-sectional area than the cross-sectional area of a single discharge line. The collection line is coupled to a separation device such that the separation device receives the biomass material and steam from the collection line.

Piping system from reactor to separator and method to control process flow

A reactor for the treatment of lignocellulosic material and related methods. The reactor includes a vessel having an upper portion and a lower portion. A pressure envelope is formed between an outer wall of the vessel and at least one lower wall of the lower portion of the vessel, and the upper portion of the vessel and the pressure envelope are operatively connected with a pressurization line, such that a pressure of the pressure envelope and a pressure of the upper portion may be equalized.
