Disclosed herein are an apparatus and method for gas leakage measurement in a high pressure reactor. In particular, the present invention relates to an apparatus for gas leakage measurement in a high pressure reactor including: a gas inlet; a first valve equipped to one side of the gas inlet; a flowmeter; a pressure gauge measuring an internal pressure of the reactor; a gas outlet; and a second valve, wherein if in internal pressure reaches a preset pressure by closing the second valve and injecting a gas to the reactor through the flowmeter in the state of opening the first valve, the gas leakage status in the reactor is measured through pressure changes in the pressure gauge after closing the first valve.

Apparatus and method for gas leakage measurement in a high pressure reactor

The present invention is directed to a high pressure fluidized bed system using dual control valves, and an inner pressure control method thereof. The high pressure fluidized bed system includes a fluidized bed reactor, a pressure sensor which measures a pressure in the interior of the fluidized bed reactor, a cyclone part which is coupled to the fluidized bed reactor, a first valve allowing controlling of the exhaust gas, and a second valve allowing manually controlling of exhaust gas except for the exhaust gas controlled by the first valve. The first valve is capable of opening and closing automatically, and the second valve is capable of opening and closing manually, and are used in combination in the high pressure fluidized bed, allowing decreasing of the pressure variation within the reactor and improving the operation stability of the reactor.

Installation and operation method of dual control valves in a high pressure fluidized bed system

Disclosed is provided to overcome problems of conventional methods using each of a solid discharge nozzle and a screw conveyer. According to one exemplary embodiment of the present invention, a fluidized bed system is provided to circulate solids using pressure and density difference. More particularly, a fluidized solid circulation system using pressure and density difference is characterized by comprising: a first fluidized bed reactor; a second fluidized bed reactor; a first cyclone; a second cyclone; a first pressure control valve; a second pressure control valve; a lower loop seal; an upper loop seal; and a control part, thereby circulating the solids between the first fluidized bed reactor and the second fluidized bed reactor.
