Development of technological measures to ensure the safety of production facilities in petrochemical industry

Abstract

Abstract This article, using the example of the production of methane oxidative ammonolysis, discusses the problems of safe process control. This is achieved by a set of precautionary measures. The industrial safety plan prevents one of the causes of technological equipment depressurization. The production of hydrocyanic acid by oxidative ammonolysis of methane is considered, in which, to prevent the vapor-gas mixture formation, it is necessary to ensure complete sealing of the apparatus in which the combustible substance is stored, and also to maintain the pressure in the apparatus equal to the design pressure. A number of technical solutions, with the help of which it is possible to ensure the operation of devices with ammonia without the formation of explosive concentrations in them, are presented. These include: the presence of a mixture of combustible gas with an oxidizing agent with a working concentration in the apparatus above the upper or lower ignition limits, taking into account the safety margin; a system for supplying a non-combustible gas having a phlegmatizing property to the reaction zone; automatic regulators of the oxidizing agent and reducing agent ratio, as well as gas pressure regulators; protection against atmospheric and static electricity; automatic shutdown of the pipeline as a result of automatic shutoff of the valve; stationary gas analyzers that automatically signal a deviation from the norm.
