| The presence of the diesel hydrotreating unit in the construction process,as a construction project to study,by using relevant knowledge of project management,a comprehensive analysis of the existing problems and shortcomings,and put forward the corresponding solution reference method for quality control of construction site analysis of construction site,qualifications of personnel,materials and equipment and the method of management,and puts forward the solution.For the petrochemical construction units to provide an effective management approach for the successful completion of chemical facilities construction projects provide a strong guarantee.According to the technical and economic evaluation,the total investment of the project is 5 billion 529 million 510 thousand yuan,the annual sales income is RMB 18 billion 184 million 740 thousand yuan,the average annual total cost is RMB $17 billion 70 million 160 thousand,and the annual income tax profit is RMB 443 million 320 thousand yuan.The internal rate of return of all investment income is 13.16%,the net profit margin of capital is $22.81%,and the total return on investment is 13.44%.This project has good economic and social benefits.In this paper,the research methods of project quality management,including the preparation of quality plan,construction process quality control requirements and quality improvement.According to the characteristics of chemical plant construction,selection of quality control factors and quality control points,the quality control of diesel hydrogenation device modification project is studied.And proposed that the quality of the phase should be changed into measures,the quality control of the high quality control water level,the guarantee certificate to set up a comprehensive set of engineering and quality of work,the increase assembly in the stone industry.In order to achieve management objectives,the construction site adoption of mandatory system,and use 4 m continuous improvement program,through the analysis of personnel,machine,materials,methods,the five factors of the change and deficiencies management,the site development and TPM management thought,let construction site environment change.After the analysis and confirmation of the problems in the site,the continuous improvement scheme,the problem may not reach the expected rectification goal once after being processed,and use the method of PDCA,continue to improve until the purpose. |
