Selection And Research For Technical Programmes Of Toxic Or Harmful Gases In The Daqing Petrolchemical CPI Plant

Daqing Petrochemical Company CPI wastewater pretreatment plant spilling out of a large number of non-methane hydrocarbon based toxic and harmful gases, leading to production areas often shrouded in a toxic gas. CPI cesspool emitting a large number of toxic and harmful gases by atmospheric pressure lowering or the monsoon and other factors, especially in the absence of wind and air pressure is low, the toxic and harmful gases will accumulate in the space around the appliance, the device number of toxic and hazardous jobs gas concentrations often exceeded, long-term physical and mental health staff that will cause harm, a serious threat to the health of employees, the current CPI has become a sewage pretreatment unit of Daqing Petrochemical Company important point sources of pollution, an urgent need for treatment, the company earlier this year project, preparation of this serious threat to the health staff to eradicate the sources of pollution, the project is needed to fully demonstrate the technical program and evaluation, have finally found a technical feasibility and economic reasonableness of the best.In this paper, Daqing Petrochemical Company CPI wastewater pretreatment unit for the study, to toxic and harmful gas treatment technology options for research purposes. This thesis includes six chapters: the first is the introduction, this paper described the background and significance of projects shows that project management theory and research content and structure of the arrangement. ChapterⅡof the project Selection of factor analysis, to identify and analyze the main factors affecting the project plan. ChapterⅢof the project options for the design, collection of relevant information, according to the characteristics and requirements of the project to determine options for the project. ChapterⅣis the preferred project alternatives, options through qualitative analysis and quantitative comparison, select the best option. ChapterⅤis the optimal scheme for the implementation of projects related to countermeasures. ChapterⅥis the full text of the summary and outlook.This systematic analysis of the gas processing design and optimization of various factors, detailed collection of gaseous organic compounds (VOCS) processing information, the current main combustion, condensation, absorption, adsorption, biological methods, membrane separation, catalytic conversion and plasma processing method of purification made eight, by these eight (VOCS) approach to analyze carefully compared and combined with the actual situation of this project, the final form of the three companies can basically meet the requirements to achieve emission compliance options, the preferred program for the next technology prepared.This article introduces the AHP (AHP), established a goal of alternative program evaluation, rule, sub-rule, and measures levels of four-level structure; constructed five alternative levels of comparison to judge matrix, the evaluation index The concept of using a weight, the establishment of the selection process toxic and hazardous gas treatment technology program optimization model; have calculated the Matrix and the combination of a single weight vector weight vector, and for the consistency test; of the other major factor, more objective reflect the full impact of the elements of the system to arrive at comprehensive conclusions. In this way, evaluation results are more reasonable for the toxic and harmful gas treatment technology optimization of the program provided a more scientific and effective methods.In this paper, the optimization model is applied in Daqing Petrochemical Company CPI Zhuangzhi Optimization gas treatment process selection, selection of alternative programs, the technical feasibility level, the safety and reliability of the biggest weight, fitness and the first of the second, to maintain The weight of the smallest; in the level of economic rationality, the weight of investment costs, operating costs, the weight is small; in the target level, the technical feasibility of the right material, the weight of economic rationality small. Through quantitative calculation, and finally reached the following conclusions: biological method for the optimal solution, activated carbon adsorption for the second-best program, absorption program for the worst.This implementation of the project preparatory work and project implementation process safety, quality and progress of process control, made a number of practical, can exercise strong practical significance of the countermeasures and suggestions for the project in the future security of high the successful implementation of quality laid a good foundation.This thesis only gas volatile organic compounds (VOCs) Central African methane hydrocarbon processing program, a preliminary study and research, the breadth and depth of research is not enough. Choice in the technical program, only more mature technologies from the current program selected, the current treatment methods such as film art of separation, Guang Deng Ion catalytic and did not conduct such Yan Jiu.This article on the toxic and harmful gas treatment technology options and research, as individuals is limited, and time is relatively short, and the depth and breadth of research are limited only.
