Design And Implementation Of DMSO Safety Sysytem

At present, our country is In the period of industrialization development. On the one hand, petroleum and chemical industry has entered a rapid development period, the size and number of dangerous chemicals is expanding, the risk of them is increasing year by year,too; On the other hand, with the development of economy and society, the people put forward higher safety requirements to various chemical industry development. Carrying out chemical safety production system in the chemical industry has many advantages :first, the system can effectively prevent and control the incidence of various accidents; second, the system can speed up the upgrading of traditional chemical manufacturing industry, therefore, there will be of important significance to strengthen the safety management of dangerous chemicals.Chemical production process always has the characteristics of high temperature, high pressure, flammable, explosive, toxic, harmful, some chemical production process is very complicated and the reaction process along with huge energy conversion, once the abnormal situation cannot be controlled improperly, the employees and the property will get huge damage. So the design of a set of emergency shutdown system has a very important significance. Based on the understanding of two dimethyl sulfoxide production equipment and production technology, a set of safety interlocking and emergency shutdown system(ESD) has been researched and designed. The system introduced design principles in detail, system hardware selection and software ideas.The system has been successfully used in the DMSO production unit of Shandong Lunan Chemical Technology Co., the practical application shows that the system fully solved various drawbacks in the old system, and ensured safe operation of the device. This system has been put into operation and achieved good results, meanwhile meet the design requirements.
