Abstract: A hydraulic drive assembly for a large pre-existing pressurized digester vessel and a method of installation of the hydraulic drive assembly have been conceived. Such a device includes a stub shaft which has a lower end and an upper end. The lower end engages with a hydraulic drive and the upper end is coupled to a drive shaft. The coupling further includes a top coupling and a bottom coupling. The top coupling is coupled to the drive shaft, and the bottom coupling is coupled to the stub shaft. A drive support bracket is attached to the hydraulic drive and then attached to the drive support bracket by at least one sole plate that is fixed to a foundation. The hydraulic drive assembly installation method is utilized when removing an electric motor and mechanical transmission device and replacing it with a hydraulic drive assembly.

Abstract: 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.
