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.

The pump space has a vacuum port or a vacuum pump connected to it.
Abstract:
The invention relates to a method for the thermal hydrolysis of sludge characterized in that it is carried out in at least two reactors operating in parallel, in each of which the sludge undergoes a complete thermal hydrolysis cycle. Said cycle comprises different stages consisting in supplying the reactor with the sludge, injecting live stream in order to bring said sludge to a pressure P and a temperature T at which hydrolysis can occur, maintaining the sludge at said pressure P and said temperature T for a certain amount of time, suddenly bringing said sludge to the atmospheric pressure by releasing the flash steam and emptying said reactor of the hydrolysed sludge. Furthermore, the inventive method consists in time shifting the cycle of one reactor to the other in order to use the flash steam produced from one reactor to inject it into the other reactor.
Abstract:
A method of treating a polymer compound has the steps of: mixing and agitating the polymer compound and a chemical agent in an extruder while controlling the inside of the extruder to be kept at a high temperature and a high pressure to have a reaction mixture containing a polymer treated product; supplying the reaction mixture continuously into a high-pressure container disposed following the extruder and retaining the reaction mixture at the high temperature and high pressure for a predetermined time; then supplying the reaction mixture continuously to a chemical agent separator to separate the polymer treated product; and supplying the separated polymer treated product continuously to a molding means to form it into a molded material.
Abstract:
A method comprises continuously supplying an alcohol to a pressurized reaction system, pressurizing carbon monoxide with a compressor 8 attached to a first feed line 22, for continuously supplying carbon monoxide to the reaction system via a second feed line 23 with a reference flow rate F, and converging excess carbon monoxide in the reaction system in the first feed line via a branched circulation line 24 for allowing to react alcohol with carbon monoxide. The reference flow rate F in the second feed line 23 is a total rate of a reference consumption flow rate Fcs in the reaction and a flow rate F1 in excess rate over a fluctuation consumption flow rate ΔFcv in the reaction system (F=Fcs+F1, F1>ΔFcv). According to the pressure fluctuation of the gaseous phase in the reaction system, the flow rate in the circulation line 24 is controlled to a flow rate Fr=F1−ΔFcv and the feed flow rate in the first feed line 22 is controlled to a flow rate Fsu=Fcs+ΔFcv, for compensating a consumption rate variation in the reaction system with the feed flow rate of carbon monoxide. This ensures discharge inhibition of the gaseous reactant in a liquid phase pressurized reaction system (such as carbonylation reaction system) and effective utilization of the reactant for the reaction.

A treatment apparatus for organic waste including a reaction vessel for introducing and decomposing organic waste and pulling out decomposed organic waste as a treated fluid. The reaction vessel includes an internal vessel made of corrosion-resistant material, an external vessel made of pressure-resistant material provided for surrounding the internal vessel via a gap, and an interconnection pipe for interconnecting the gap and the internal vessel outside the external vessel, thereby to control inside the gap and inside the internal vessel to practically equal pressure. The internal vessel has a heating zone for heating the introduced organic waste to a temperature higher than a critical point of water, a reaction zone for holding and decomposing the organic waste at a temperature higher than the critical point of water, and a cooling zone for cooling the treated fluid containing a decomposition product of the organic waste to lower than 100° C. The gap is adapted to be charged with high-pressure water or hydrogen peroxide water.
