The Evolution of DOW Security-Evaluation and It's Computerized

The fire and explosion index assessment system of DOW's chemical company is widely used in the system safety estimate.This method can describe the exact possibility of fire and explosion according to the index choosing rules.Aiming at the shortcomings of the method such as:complicated process, huge calculation, difficult to find matter parameter, difficult to change the choice.This paper introduces how to develop automatic computer software.The matter parameter database uses the international popular chemicals security technology introduction MSDS database.The software can search matter parameter itself.It makes the security-evaluation become automatically, operates easy and fast.According to use the computer-aided DOW security-evaluation at the glycol reactor in the ethylene production process, proves that this automatic software has practical value in the engineering app lication.
