Title:
アクロレインの製造および青酸の製造からの排ガスを熱的に後燃焼させるための方法
Document Type and Number:
Japanese Patent JP6504744
Kind Code:
B2
Abstract:
The method of thermally after-burning the waste gas flows developing during the production of acrolein and during the production of hydrocyanic acid in gas phase processes, comprises supplying the waste gas flows from the production of acrolein and from the production of hydrocyanic acid to a joint thermal after-burning process. The waste gas flows resulting in the production of hydrocyanic acid in the gas phase process are gas flows resulting from the Andrussow method and gas flows from the blausaure-methan-ammoniak-hydrocyanic acid from methane and ammonia process. The method of thermally after-burning the waste gas flows developing during the production of acrolein and during the production of hydrocyanic acid in gas phase processes, comprises supplying the waste gas flows from the production of acrolein and from the production of hydrocyanic acid to a joint thermal after-burning process. The waste gas flows resulting in the production of hydrocyanic acid in the gas phase process are gas flows resulting from the Andrussow method and gas flows from the blausaure-methan-ammoniak-hydrocyanic acid from methane and ammonia process. The waste gas flows resulting in the production of acrolein in the gas phase process are waste gas flows from the process of gas phase oxidation of propylene to acrolein. The production of acrolein and hydrocyanic acid takes place in a parallel time and at one location so that the waste gas flows from the production of acrolein and the production of hydrocyanic acid also occur in the parallel time and at one location. The thermal oxidation is carried out in an integrated process for the chemical synthesis of methionine or methionine hydroxy analogue.
