The steam saving device for a steam explosion system for the hydrothermal pre-treatment of biomass comprises a tubular bodywith a first open endand a second open end. The first open endbeing adapted to be coupled to an outlet openingof a steam explosion reactor vessel, the second open endbeing adapted to be coupled to a discharge line. The inner surfaceof the tubular bodyof the nozzlemay comprise an engraved helical structure

Steam saving device

The present invention is directed to an energy-efficient and environmentally friendly process for the production of chemical target compounds from cellulosic material. In a further aspect, the present invention is directed to a system for conducting the process according to the inventive process.

Energy-efficient and environmentally friendly process for the production of target chemical compounds from cellulosic material

A process for the decomposition of biomass-material includes subjecting a lignocellulose-containing biomass-material to comminution, subjecting the comminuted lignocellulose-containing biomass-material to a sifting to separate from the comminuted lignocellulose-containing biomass-material a fraction of small-particles, and subjecting the remaining comminuted lignocellulose-containing biomass-material to a pretreatment. Before, during, or after the pretreatment, small particles can be added to the remaining comminuted lignocellulose-containing biomass-material. Optionally, the small particles can be added continuously during the pretreatment. The addition of small particles decreases friction of the remaining comminuted lignocellulose-containing biomass-material results in decreased process time, energy savings, and reduced production costs.

Process for the decomposition of biomass material

The present invention relates to a process for reduction of energy consumption during the pretreatment of biomass.
