化工产品涉及到衣、食、住、行等多个方面。现代社会几乎离不开化工产品,化工已成为人类文明的标志。例如汽车化学品、农药、生物制品、化妆品、医药、添加剂、涂料都涉及化工。化工是化学工业的简称,化工技术的应用推动了经济发展、生产力的提高及产业优化。但化工行业是高危行业,生产过程具有一定危险性。仪表在化工生产中起着重要作用,仪表失准或故障将可能引起安全事故,智能自动化技术在化工仪表中的应用能大大提高化工生产安全系数。本文将针对化工仪表中智能自动化的应用展开分析和研究。 相似文献

This paper describes a set of videotapes on chemical process safety produced by Wayne State University and BASF Corporation. The intent of the videotapes is to provide instruction on the application of safety procedures and process safety technology in a chemical pilot plant development area and the application of proper safety procedures in a laboratory. 相似文献

The American Institute for Chemical Engineers formed the Center for Chemical Process Safety (CCPS) in March, 1985, shortly after the Bhopal tragedy. CCPS has published several technical guidelines and has sponsored needed research projects to fill gaps in technology. In addition, CCPS has sponsored several international symposia in the interest of providing forums for the interchange of the latest technology in the prevention of catastrophic events. 相似文献

The Occupational Safety and Health Administration (OSHA) has been required by the Clean Air Act Amendments of 1990 to promulgate a process safety management (PSM) standard for the prevention of catastrophic incidents and to protect the safety and health of employees in the covered plants. The law requires the OSHA standard to cover at least 14 areas or issues and to cover highly hazardous chemicals which include toxic, flammable, highly reactive and explosive substances. The paper will describe in detail how OSHA has responded to this statute and what we have accomplished in the rulemaking effort. Also the interface with other relevant OSHA standards, including the Hazard Communication standard, the Hazardous Waste Operations and Emergency Response standard, the Control of Hazardous Energy Sources (Lockout/Tagout) standard, and others will be discussed. In addition other recent laws that relate to and impact the OSHA PSM standard such as the Hazardous Materials Transportation Uniform Safety Act of 1990, the Oil Pollution Act of 1990, and the Superfund Amendments and Reauthorization Act (SARA) of 1986, will be explained as to their relationship to PSM. The emergency preparedness efforts required of employers under PSM and the relationship to SARA Title III efforts by local community emergency response organization will be covered, as well as the interface with the EPA Risk Management Program initiative that EPA must do under the Clean Air Act Amendments. 相似文献
