Research on safety assessment of craftwork of distilled C2 adding hydrogen based on Dow

Utilizing the assessment method of dangerous index of fire and explosion by Dow Chemical Company(7th edition) to calculate and estimate the dangerous of fire and explosion for acetylene reactor.The result indicate that the fire and explosion dangerous rank is highest. In order to reduce the reactor's dangerous degree,a new idea which applying effective safety equalize measures to reduce its cell dangerous degree was advanced. Analysis results show the reactor's dangerous degree can reduce by improving safety reactor aimed at some equalize coefficients, and some feasible and cogent gist to avoid greatest dangerous source occuring fire and explosion can be obtained. 1fig.,6tabs.,8refs.
