兰州炼油化工总厂新建的250万吨/年二套常减压装置于1990年5月21日正式进油投产,实现了开车一次成功。该装置由洛阳石化工程公司设计,兰炼安装公司安装,装置总投资为5400万元。二套常减压装置的设计,吸收了当前国内同类装置的经验,并针对兰炼的具体情况,采用了一系列新技术,优化了生产过程。它的优点表现在:一是首次采用了集散型计算机控制系统,结束了该厂几十年来用二次仪表控制生产流程的历史。这套美国福克斯波罗公司的新一代集散系统,具有可靠性强,维修方便,便于
Lanzhou Refining & Chemical Plant newly built 2.5 million tons / year two sets of atmospheric and vacuum unit was officially put into operation on May 21, 1990, to achieve a successful car. The device is designed by Luoyang Petrochemical Engineering Company, Lan Lian installation company to install a total investment of 54 million yuan device. Two sets of atmospheric and vacuum equipment designed to absorb the current experience of similar devices in China, and Lan Lian for the specific circumstances, using a series of new technologies to optimize the production process. Its advantages are as follows: First, it adopts the distributed computer control system for the first time, ending the history that the plant used the secondary instrument to control the production process for several decades. This new generation of American Foxboro distributed system, with reliability, easy maintenance, easy
