Abstract:Because of the global terrible demand for high-quality oil, hydrocracking technology has become indispensable to modern society, especially in today when an environmental problem is increasingly serious. For example, the outbreak of the greenhouse effect has made people starve for the high-quality and environment-friendly hydrocracking process more than ever. China’s efforts in developing the hydrocracking technology reflect in several aspects. In order to meet the expanding needs for jet fuel, high-quality petrochemical materials, China has introduced advanced hydrocracking unit from United States and Germany, which has already been put into practical use. Moreover, our country will continue to attach importance to the development of hydrocracking technology in the future.This paper describes the hydrocracking technology and related simulation operating under the background of the new century. The full text consists of 6 chapters, which includes introduction, the technological process of hydrocracking unit, control system for hydrocracking unit based on force control platform, design for PLC control system, the connection between force control platform and PLC control system, making conclusions and expectation. 源¥自%六:維;論-文'網=www.aftnzs.live
