However, due to their characteristic chemical industry trade reasons, if not handled properly, prone to heavy, oversized fire explosion, which caused casualties and property losses are difficult to predict. In the entire history of human civilization, humans since learned to use fire, has been constantly in and live in for a tough fight. The glyoxal itself there is a certain danger in case of fire explosion could cause serious consequences not the intention, therefore, to this issue.
In this paper, "Synthesis of new technology glyoxylate oxidation method" for a company developed the first set of production equipment. Carrying 200 tons in the pilot plant design process, the company needs to glyoxal solution under pure oxygen, air and other conditions, the reaction temperature is in the range of 40-120 ℃, the oxidation process in relation to the existence of material fire, explosion possible validate the analysis and prediction on the fire and explosion risks, and make the process of assessment, detection of combustible gases and produce results for analysis, and to explore the possible consequences.
In this paper, a number of related experiments, some of the physical and chemical characteristics of glyoxal some analysis, trying to figure out the impact of a number of factors glyoxal oxidation rate and regularity. Experiments done by experimental results obtained based on the use of Dow Fire and Explosion Index evaluation method for a certain amount of heat glyoxal risk assessment, draw some fire risk assessment related.
Based on the qualitative and quantitative safety assessment of glyoxal and major hazard identification of glyoxal obtained enterprise security risks necessary appropriate security measures in enterprise security management to its production of the storage process risks and dangers and consequences of equipment and technology related to hazardous chemicals substance of the relevant employees related production safety education and increase the number of relevant security sufficient warning signs, to the need to take immediate action to safety measures switch control should be located in the operating room, full corporate security education for similar problems, and with the necessary information related to entering into the exchange, so that people understand some of the relevant stakeholders emergency protective measures. Fire safety facilities in the same enterprise made related requirements.
Although safety has been a major item of the project, but the accident is because of security problems often can not pay attention to people's fundamental, especially in the chemical industry in the production and management, people often and pursue short-term interests, but only the production efficiency security ignored by some of the characteristics of the chemical industry in itself affect the event of fire explosion not only production and operations will be affected, the accident caused by a series of personnel casualties, property damage is enormous. In order to avoid accidents, and only rely on scientific and feasible security technology, security and effective management approach combined with each other in order to better protect the health of employees and property are not subject to loss, damage.
