Pressure regulated multi-reactor system

Abstract

#CMT# # / CMT# The device comprises first and second (9) reactors connected to each other for continuous operation with contaminants. The first reactor is connected to a jet pump (8) using a pipe. The jet pump is capable of generating a negative pressure in the first reactor. A low pressure zone of jet pump is operatively connected via a thick line to the first reactor, so that in operation, a first fluid product of the first reactor passes through the pressure zone in a drive beam of a propellant to the jet pump. The drive beam is directed to the second reactor. #CMT# : # / CMT# The device comprises first and second (9) reactors connected to each other for continuous operation with contaminants. The first reactor is connected to a jet pump (8) using a pipe. The jet pump is capable of generating a negative pressure in the first reactor. A low pressure zone of jet pump is operatively connected via a thick line to the first reactor, so that in operation, a first fluid product of the first reactor passes through the pressure zone into the jet pump using a drive beam. The drive beam is directed to the second reactor for collecting a propellant along with the first fluid product. The line between the first reactor and the jet pump at the inner surface is free from moving parts such as pumps, fans or mixers. The device further comprises a heat exchanger and a condensate trap located in line between the first reactor and the pump, and a blowing unit for generating an absolute vacuum pressure of = 250 hPa at a temperature of 70[deg] C. The first reactor is maintained at a temperature of 300[deg] C. The blowing unit is controlled by flow of negative pressure in the first reactor. The first product is a thermolysis or pyrolysis product, and the first reactor is a thermolysis or pyrolysis reactor. A pressure of the first reactor to the second reactor is the negative pressure. The blowing unit contains an acid or base, and the reaction in the second reactor comprises an acid-base reaction. The propellant is a liquid. The second product is a gas. An independent claim is included for a method for reacting a starting material in reactors. #CMT#USE : # / CMT# The device is useful for reacting a starting material in reactors (claimed). #CMT#ADVANTAGE : # / CMT# The device allows reaction of the starting material in the reactor with high safety in a simple and a rapid manner, is economical to maintain, and has increased service life. #CMT#DESCRIPTION OF DRAWINGS : # / CMT# The figure shows a schematic view of structure of a device for reacting a starting material in reactors. 1a : Container 3a : Reactor zone 8 : Jet pump 9 : Second reactor 12 : Surge tank.

Description

technical field [0001] The present invention relates to the field of chemical process technology for substances that tend to contaminate devices. Background technique [0002] During the course of various chemical reactions, by-products are often formed in addition to the desired products. Likewise, the product may become unstable under different conditions and likewise lead to the formation of by-products, for example by decay or agglomeration. Some by-products can damage reaction systems simply by virtue of their presence, adhesion or by reacting with accessible system components (eg seals), which can only be removed by costly cleaning or maintenance. The cleaning process can interrupt production for a considerable time. The transport of polluting by-products over relatively long distances in chemical plants is therefore generally avoided and separated and removed as quickly as possible. In some cases, such as when unstable products are present, this is unlikely. In su...
