Based on the analysis of fire and explosion risk factors in the production process flow of TDI, the safety assessment of TDI production equipment was conducted using the evaluation method of fire and explosion risk index of Dow Chemical Company. In view of its actual operation conditions, a systematic analysis of various process units from the aspects of general process hazards, special process hazards, and safety compensation measures was conducted, and safety countermeasures for accident prevention were proposed to provide safety and production management for TDI. Practical reference. TDI, also known as ** diisocyanate (C6H3(NCO)2CH3), is an important chemical raw material for the production of polyurethane materials. It is mainly used for the synthesis of polyurethane (PU) foams, coatings, adhesives, elastomers, etc. Its applications include transportation, construction, Appliances and other industries. The production process of TDI is complex. Some reactors and storage tanks are characterized by high pressure and high temperature, raw materials and auxiliary materials in the production process.
