Embodiment

[0032] The embodiment of the present invention provides a fine chemical reaction safety risk assessment method, including the following content:

[0033] 1. Obtain parameters

[0034] 1-1. Determine the chemical process route, the number of raw materials required to obtain the target product X, the number of reactions required in the process Y, the chemical process is three raw materials undergoing two-step reactions to obtain the target product, then X=3, Y =2, the more types of raw materials and the number of reactions used in the chemical process, the greater the potential risk in the relative production. This item is extremely risk assessment for the chemical process route itself;

[0035] 1-2. In order to obtain the target product, multiple reactions need to be carried out. The number of reactions is Y, and the environment of each reaction is different. It is necessary to evaluate each time, and take the most dangerous one as the evaluation standard , to obtain the proce...

Abstract

The invention provides a fine chemical reaction safety risk assessment method, and relates to the field of chemical risk assessment. The method comprises the following steps: determining a chemical process route, preparing to acquire the variety number X of raw materials of target product, reacting Y times in the process to acquire process temperature TP, adiabatic temperature rise rate delta T, maximum temperature Tmax capable of being reached under adiabatic, and volume L of a reaction kettle; space proportion Z of the materials in the reactor, the mass of the materials M, the pressure resistance value of the reactor Pmax to acquire response time t of emergencies in the chemical production process and the frequency of emergencies a, namely, one production is performed on average, a emergency situation occurs, and calculation, analysis and evaluation are performed. The risk in chemical production is comprehensively judged through a chemical process route, raw materials, factory equipment and factory emergency treatment measure time.

Description

technical field [0001] The invention relates to the technical field of chemical risk assessment, in particular to a safety risk assessment method for fine chemical reactions. Background technique [0002] The chemical industry is a multi-variety basic industry. In order to meet the various needs of chemical production, there are many types of chemical equipment, and the operating conditions of the equipment are also relatively complicated. According to the operating pressure, there are vacuum, normal pressure, low pressure, medium pressure, high pressure and ultra-high pressure; according to the operating temperature, there are low temperature, normal temperature, medium temperature and high temperature; most of the processed media are corrosive, or flammable, Explosive, toxic and highly toxic, etc. Sometimes for a specific equipment, there are both temperature and pressure requirements, as well as corrosion resistance requirements, and these requirements are sometimes mutu...
