TH22345B - Methods for the production of acrylonitrile - Google Patents

Abstract

The invention relates to a method for producing acrylonitril containing The process of reacting propylene, ammonia, and oxygen molecules in the catalyst's presence in contact with the reactive gas with a liquid containing water. And acid in Quenching Town Multi-step power Which has three or more chambers And deliver the liquid in contact with the gas In the second Quenching chamber to the first Quenching chamber According to this invention High boiling point compounds were effectively isolated with The efficiency and retardation were prevented in the acrylonitrile recovery process in order to increase the acrylonitrile production capacity.

Claims (2)

1. A method for the production of existing acrylonitrile of a catalyst. Contains at least one ammonia reaction, an oxygen molecule and a reagent. Substances are selected from propylene and propane groups to form reactive gases exposed to liquids containing water and acids in a multistage quenching tower. At least three quarters of the sleeping chamber, the first quenching chamber were arranged in the section. The base of the Quenching Tower, the second Quenching Chamber, was set right above the Quenching Chamber. The closing Quenching Chamber and the Third Quenching Chamber were closely held above the Quenching Chamber II closely and sent. The liquid in contact with the gas that reacts in the second quenching chamber to the first quenching chamber. 2. Method for the production of acrylonitrile according to claim 1, where the quantity of The liquid in contact with the gas that reacts in the quenching chamber is sent to the quenching. The first chamber is 10% to 60% by weight of the volume of fluid being thrown from the drain. The liquid transporting liquid from the Quenching Chamber above the Quenching Chamber is higher than the volume of The liquid was sent from the second quenching chamber to the first quenching chamber.
