Research and Evaluation Analysis of Oxygen Generation of Steelmaking Company based on DOW

With the development of industrial oxygen process, the production of oxygen in workshop is complex and changeable.This paper discusses the applicability of Dow chemistry method in oxygen making process evaluation from material factors, equipment factors, process factors. Through the calculation of the process of fire, explosion index, evaluation of fire and explosion hazard degree,we finally figure out the safety measure compensating coefficient and the maximum possible loss of property etc. The results show that the process of fire, explosion base MPPD proportion is 41%, after taking the process control, physical isolation and three class fire safety measures for comprehensive, we can control the fire and explosion accidents effectively, thus reduce property loss to 25.9%.
