| JiLin Petrochemical Co in the country to revitalize the northeast old industrialbase to promote, the expansion of the10million tons refinery and one million tonsethylene project, the corresponding downstream products industry chain ofAcrylonitrile with propylene. In order to reach before and after the engineeringfacilities and balance, deepening to fine processing methods, JiLin Petrochemical Codecided to expand the Acrylonitrile project. Planning expansion scale：212000tonsper year expansion of420000tons per year.The project construction of petrochemical industry must be combined with itsown characteristics of the industry to carry out, it is necessary to consider theconstruction period, construction quality and. The schedule and the quality has beenthe two aspects of contradiction in the process of the construction projects, how tocontrol and coordinate is the key of project management. On the one hand, will affectthe device put into operation, losing to seize the market opportunities. Specifically,leading to idle equipment aging, missed the equipment running prime time, affect thedevice optimization and stable operation, the indirect effects of the product cost andprofit ability. Opportunity transient, in order to seize business opportunities, chemicalconstruction project is always on the project for the first request, to meet the schedulerequirements, and then try to consider the construction quality of the maximumpossible. This is the common understanding of the chemical industry construction.Jilin Petrochemical Acrylonitrile plant in1997has been completed and put intoproduction of Acrylonitrile device of the first set of66000tons per year, repeatedtransformation has now reached106000tons per year production capacity ofAcrylonitrile. In2003, the enterprise should the potential, Acrylonitrile device secondsets of106000tons per year new. In the construction of second sets of Acrylonitrile process, focusing on the progress of the project, with only8months to achievecompleted and put into production, the creation of the world history of Acrylonitrileindustry building100000tons Acrylonitrile plant construction period is the shortestrecord. Due to the neglect of quality control, so that the plant put into operationbefore the existing defects and deficiencies, leading to drive, often due to equipmentand construction quality problems and parking overhaul. Through continuousimprovement and perfection of the past2years, second sets of Acrylonitrile devicedefects existing in the project construction process and the insufficiency, havegradually been eliminated, device gradually stabilized.At present, there are10Acrylonitrile production enterprises of the country, atotal of13sets of production equipment. In2011and2012, with the industry the mostmanufacturers are Acrylonitrile running time of8000hours or more, the annualaverage load rate above100%. Jilin Petrochemical Co420000tons of Acrylonitrileproject since2010June driving, operating rate and loading rate has been lower thanthe same industry manufacturers, which did not reach design capacity. The downwardtrend in prices of Acrylonitrile under the same industry market, Shanghai SECCO,Daqing Qilu acrylic polymer factory and Acrylonitrile plant capable of continuoushigh operating rate and high load operation of Jilin Petrochemical Co,420000tons ofAcrylonitrile project starts and load rate is low, productivity is not up to the design,research on Evaluation of Jilin Petrochemical Co420000tons of Acrylonitrile project,is the formation of the Jilin Petrochemical Co consensus from top to bottom, namelyanalysis of420000tons of Acrylonitrile project contrast, further to find the gap, tofind a breakthrough to fall this synergism, raise economic benefits to provide ideasand background.Post project evaluation is based on the project has been completed and put intoproduction after the subject, system of related engineering projects decision, designand construction, completed and put into production, production management andother aspects of the objective evaluation, can improve the level of project decision,design and construction level, production capacity and economic benefits, but also toenhance the introduction technology, equipment and the success rate of control ofconstruction cost function. This paper adopts the method of investigation and analysis of industry devicesimilar quantitative evaluation, through the project objectives, project implementation,project evaluation, project benefit evaluation of impact assessment and projectsustainability evaluation five aspects, the objective evaluation of design andconstruction, involving Acrylonitrile project completed and put into production,production management and other aspects of the project, found can give full play toexisting propylene, ammonia resource advantage, the enterprise human resourcesadvantage, capital advantage and better public works and auxiliary engineeringadvantages, the effective use of the stock of assets, with less input to higher output,realize state-owned asset and. The project will enable the Jilin Petrochemical Co tobecome the largest production base of Acrylonitrile, Acetonitrile, a device the size ofthe effect will appear, a strong increase in Jilin Petrochemical Co’s creation ability.The project is conducive to Acrylonitrile downstream ABS resin, MethylMethacrylate, industry scale development, improve the downstream of Acrylonitrileon the overall economic benefits. Technical progress on the project driven by existingAcrylonitrile unit, further saving energy, reducing consumption, improving productmarket competitiveness and ability to resist risks, has become a new economicgrowth point for sustainable development of enterprises. The quench tower and theJilin Petrochemical Co’s own technology, makes the Acrylonitrile recovery ratereached95%, the four effect evaporation rate reached70%. The project a unified setof DCS control system and SIS safety instrumented system. The application of thesetechniques to other Aacrylonitrile project, is of great significance, is a major brightspot in new construction and renovation and expansion device.Study on Evaluation of the project, for the construction of Acrylonitrile projectsto provide reference. The Acrylonitrile gas cooler as the priority among prioritiesAcrylonitrile project, if the equipment imported manufacturer, manufacturing cycle isone year. The localization of cooler Acrylonitrile synthesis gas, manufacturing cyclefor half a year, the manufacturing cost is about one-third of imported equipmentmanufacturing costs. For an engineering project in the same industry, in the projectshould take into consideration the production mode, the device, which is the key ofAcrylonitrile project to create profits and benefit maximization. For me, Acrylonitrile project opportunity transient, time will not wait for me. Inthe future, the construction of an engineering project, especially the selection ofprocess route and the catalyst can also be used for reference. For an engineeringdesign and construction, completed and put into production, the production andbusiness operation analysis and evaluation to find out the reasons for the success orfailure, sum up experience and lessons, and through the feedback information timelyand effective, for future project decisions and to improve the management level ofinvestment decision-making recommendations, at the same time, Acrylonitrile projectis evaluation of the implementation of the operational problems of recommendationsfor improvement, and to increase the investment profit. |
