In short, the indicators have been fully met or exceeded, and has made great economic benefits and impact of the going concern ability.In order to study and note 2 million ton / year heavy alkylbenzene sulfonate unit renovation project post-project evaluation, this paper is divided into four parts are described:First, 20,000 tons / year heavy alkylbenzene sulfonates and status quo analysis of project brief.20,000 tons / year heavy alkylbenzene sulfonates Plant Reform Project in August 2005 started in April 2006 began trial production, according to the preliminary design approval, the project was completed in early 2007 for completion and acceptance. After more than two years of production debugging, by the end of 2009 to begin the latter part of the project evaluation, the overall achievement of the project feasibility study for the construction of the initial request. .The evaluation of large-scale projects are usually divided into two phases, pre-evaluation stage mainly refers to the project pre-construction feasibility studies and project construction, construction supervision, while the latter refers to the evaluation stage the projects after completion of the project evaluation of the overall construction and commissioning period of time Evaluation of the production operation and economic efficiency evaluation.Daqing oil field has now entered the third phase of ASP flooding is higher than the added value of its oil recovery polymer flooding nearly doubled the advantage, will become the main force of Daqing Oilfield EOR technology. According to the deployment of China National Petroleum Corporation, from 2006 onwards has started a new open-industrial test blocks to explore the experience of 2010 is expected to achieve industrial application of ASP flooding. ASP flooding the most critical ingredient is surfactant. Dong ho company has been dedicated to the research and development surfactant production is ASP Flooding in Daqing area with the sole surfactant production and supply manufacturers, production capacity of 2-3 million tons by the end of 2010 and then gradually expanded as the use of production.Second, Related to post-project evaluation studies content.Post-project evaluation study is an extension of the project management work, usually in the running for some time after the completion of the project or investment of direct economic benefit of play after the. Post-project evaluation of investment in public works projects program is an important phase of its work is project work in investment management an integral part and important part.Compared to pre-assessment of post-evaluation study, apart from the evaluation point in time different from the following three main characteristics of a comprehensive analysis, feedback, monitoring and exploring the future. The significance of post-evaluation study to test the previous prediction and evaluation of the authenticity and reliability, a comprehensive summary of construction projects of the decision-making, implementation and operation, and to analyze the process of the project, technical, economic, social and environmental benefits and impact of the building engineering decision-making and project management to provide lessons to improve and perfect the projects have been completed to improve their sustainability, enhance project management capabilities. Post-project evaluation report of the basic content can be reduced to five areas, namely, evaluation of the project objectives, project process evaluation, project benefit evaluation, project impact assessment and project evaluation continues.Third, 20,000 tons / year Alkylbenzene Sulfonate project construction and production evaluation.Project construction and production processes are mainly based on post-evaluation process and results of the implementation of projects on the construction process in the organization of the project, the project to conduct qualitative and quantitative change analysis and evaluation.In the building evaluation, construction plans using advanced and reliable new technologies, new processes, new processes, new equipment, construction design in line with national, industry, design specifications and standards. Works with project manager responsibility system, regulatory agencies sound, standardized operation, scientific management and efficient construction fully prepared and reasonable construction organization. The construction schedule, quality and investment has been effectively controlled, project completion time limit according to plan, the units works, sub-division of engineering and engineering quality pass rate 100%. Completion and acceptance of all the procedures are in line with national and Petroleum and Natural Gas Corporation-related documents, reflects a higher level of project management.In the production evaluation, production preparation procedures are rational, well-organized, plan properly, personnel, technology, materials, security, external conditions, and management of the preparation work is solid and effective, to meet the needs of test and production runs. Since the plant was in production operation, stable supply of raw materials to meet production requirements. Continuous optimization of process parameters, installation and stable operation. Equipment and control systems in the actual running, well-functioning, operational indicators and the design parameters are basically consistent.Forth, 20,000 tons / year Alkylbenzene Sulfonate cost effectiveness of projects and impact evaluation.In the cost-effectiveness, the actual investment of the project feasibility report and compared to estimates there are more substantial savings, savings of 6.6778 million yuan, saving rate reached 16.69%. After-tax profits than the feasibility report predicts that a relatively large increase in value. During the operation to predict the future is expected to continue to achieve better returns. Feasibility report in accordance with the method of calculation, the average annual after-tax profit of 58.2884 million yuan, the internal return rate of 128.23 percent, higher than the feasibility study report predicted value, and to achieve the main objective of the project construction. Financial net present value of 228.0119 million yuan, the project's economic good.In the social impact, "three wastes" emissions to meet the requirements, environmental impact less. After more than two years of production equipment operation, production capacity is gradually increased. The project advanced process technology, devices running smoothly, raw materials and less energy-intensive; products of good quality, the factory has always been to maintain 100% pass rate, good rate is also rising. As the international crude oil prices continued to rise, the phenomenon of increased domestic energy shortages, coupled with the Daqing oil field declined steadily, stable oil production as Daqing oil field an arduous political task, the current market demand exceeds supply. In summary, the project environmental impact, social impact of a good, competitive ability, and has a strong capacity for sustainable development. |
