  • Method for producing compound and compound production system used in production method
    Patent number: 10662449
    Abstract: This method for producing a compound uses a continuous tank reactor which is provided with two or more reaction tanks for producing the compound and with a reaction liquid feeding pipe that feeds a reaction liquid from an upstream reaction tank to a downstream reaction tank, said method being characterized in that the Reynold's number of the reaction liquid that flows in the reaction liquid feeding pipe is configured to be 1800-22000. Furthermore, this compound production system is used in said method for producing a compound, and is formed by housing at least one of the reaction tanks in a portable container.

  • Apparatus and method for catalytic combustion
    Patent number: 7618255
    Abstract: A catalytic combustion apparatus is equipped with a reactor for catalytically burning a gas to be treated containing a combustible organic compound, which further comprises a condensate forming means for condensing a part of a gas after reaction in the reactor, to form a condensate, and a pH measuring means for measuring a pH of the resultant condensate. It is preferred that the catalytic combustion apparatus still further comprise a temperature adjusting means for adjusting a temperature of at least a catalyst-packed portion of the reactor based on data measured by the pH measuring means.

  • Method of removing tacky substance or waste liquid containing tacky substance
    Patent number: 7422640
    Abstract: A method of removing a sticky substance or a waste liquid containing a sticky substance which comprises, mixing a solid substance having inflammability and liquid-absorptivity into the sticky substance or the waste liquid containing the sticky substance wherein these are mixed to allow a liquid component of the sticky substance or the waste liquid containing the sticky substance to be absorbed into the solid substance and to allow the sticky substance to be entangled with the solid substance, and then removing the sticky substance together with the solid substance.
