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

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.

Analysis of the influence of sustainable development factors on the state of the housing function in a large city

“…for the entire estimated service life of this building and further disposal. At the same time, it is necessary to take into account the fact that the savings from choosing the most heat-saving building material in the end for the entire life cycle of a building with a short service life will be less than when choosing a less heat-saving, but at the same time less energy-intensive in production and more environmentally friendly, and with a long service life during the life cycle [7]. Thus, energy and resource conservation, improving the energy efficiency of buildings, is an important factor in the sustainable development of urban housing stock.…”

Research on Petrochemical Production Safety Management Based on HSE Management System

“…Some define "production safety" as a series of safety measures and guarantee activities to form a good labor environment in safe and effective work order, to prevent unnecessary personal injuries during the production process, and to ensure the normal operation of the equipment. [1] Some interpret "production safety" as an important policy in the production process to ensure that the lives of workers are effectively protected. The management of the enterprise should take production safety as the highest principle to comply with, and effectively protect the workers from work-related accidents and occupational diseases so that the life and health of workers are effectively safeguarded in the production process.…”

Composition of molding material for ceramic tiles

“…With a further increase in temperature to 1100 0 С received modifications γ-Al2O3, η-Al2O3, χ-Al2O3 pass, respectively, in the modifications δ-Al2O3, θ-Al2O3 and κ-Al2O3. At a temperature 1100-1200 0 С all modifications go to α -Al2O3 [10,11].…”
