REACTOR, METHOD AND PLANT FOR PRODUCTION OF AMMONIUM SALTS Russian patent published in 2000 - IPC

FIELD: production of ammonium salts. SUBSTANCE: reactor for production of ammonium salts has tubular reaction chamber 110 at least one device 112 for supply of acid, and at least one device 111 for supply of ammonia located in the first part R1 of reactor with respect to direction of flow. Reactor has the second part R2 located in extension of the first part and contains in the direction from top to bottom of flow: narrowing section 122, cylindrical part 121 and expanding section 123. Reactor second part is provided with at least one second device 124 for supply of ammonia which runs into the second part of reactor in vicinity of the narrowing section and which is regulated so as to obtain at outlet of reactor of basic vapors or vapors with basic reaction. Subject of the present invention includes method and plant for production of agricultural fertilizers, particularly, nitrates. EFFECT: reduced and even fully excluded corrosion of reactor and ammonia losses and higher efficiency of neutralization reaction. 21 cl, 6 dwg
