US 6,206,658 B1 · Organic substance processing system and organic substance processing apparatus

Abstract

Fluid containing organic substances, which has not processed yet, is fed to a plurality of cylinders, using a slurry pump. A free piston is included in each cylinder, the fluid which has not yet been processed is introduced into one of two chambers in the cylinder partitioned by the piston, and processed high-pressure fluid which has been processed is introduced into the other one of the two chamber in the cylinder. The piston pressurizes the fluid with which the cylinder has been filled up. A pressure holding valve is provided in a processed high-pressure fluid system to pressurize an organic substance processing system, and this pressure holding valve suppresses changes in the pressure in the processed high-pressure fluid system. By changing the timing of feeding the fluid before processing into each cylinder, it becomes possible to unbrokenly perform the filling-up of each cylinder with the fluid to be processed, the pressurizing of the fluid to be processed in each cylinder, and the feeding of the pressurized fluid to a reactor. Thus, stable continuous processing of the fluid to be processed can be realized.

Dependent claims

An organic substance processing system for processing organic substances in a reactor by pressurizing fluid which contains organic substances with a plurality of cylinders including pistons, respectively, and by feeding said pressurized fluid into said reactor, said organic substance processing system comprising:

a first chamber formed on one side of each cylinder, into which said fluid containing said organic substances is introduced;
and
a second chamber formed on the other side of said cylinder, into which processed high-pressure fluid is introduced, said organic substances in said fluid having been processed;
wherein, by alternately changing the timing of pressurizing said fluid which contains said organic substances in each cylinder, said pressurized fluid is continuously fed to said reactor.
