1.5Million Tons/Year Of Catalytic Cracking Ethylene Plant Two Installation Technology Was Studied

With the increasing of scale of the refining units at home and abroad, including in the crude oil deep processing of secondary processing process of catalytic cracking a single set of device scale will increase accordingly. So for catalytic cracking unit in the core equipment of the two (behind the reactor and regenerator, are referred to as the\"two") from the design and installation Angle put forward higher requirements. So really so big two, whether in the installation process quickly and efficiently meet the design requirements, I want to pass this article summarize and study the current domestic biggest catalytic cracking unit (jingbian-yanshuiguang pipeline industrial park1.5million tons/year catalytic cracking ethylene plant, the device size is equivalent to4.8million tons/year of catalytic cracking unit) installation process, from start to build at the same time from two into production running normally, validation, and test the installation process can meet the design requirements, therefore a similar devices in the future study was very large two control points of the installation process, i.e., the very large two installation progress control measures, technical quality control measures of each link, the large diameter cyclone separator group of technology and precision control technology, and more than two unit to the wall of large diameter reinforcement technology application and technical standards. So that very large two technology get rapid promotion.Based on the catalytic cracking unit of past experience and the technology of two device installation and application in jingbian-yanshuiguang pipeline industrial park1.5million tons/year catalytic cracking ethylene plant (the equivalent of4.8million tons/year of catalytic cracking unit), first of all, according to the characteristics of the two machine installation, for installation process schedule modular control, find two installation schedule control key lines, through modular prefabricated installation process control, grasp the key point of circuit, so as to optimize two installation technology progress and improve the installation efficiency of the two; Second:according to the key circuits of the installation process, and optimize the quality control points in various manufacturing and construction process and quality control measures; Again:by studying the two machine shell wall opening reinforcement technology and multiple embedded away should be heat treatment technology，formulate the construction technology standard; Finally: group within the inner core of twopieces of cyclone separator for technology， developed a large two unit cyclone separator ingroup two implement internal control measures of construction process and installationaccuracy.This article also for embedded reinforcing hole by hole， stress verification， and thecyclone system of two different installation methods and measures of different designinstitutions influence was analyzed， the conclusion， put forward the reinforcementembedded in the structure of the application of two rationality as well as different forms ofcyclone separator design ensure the installation precision control method.
