Analysis Of Water-using And Optimization Of Water System In HuaBei Petro-chemical Company

With the great rise of the crude oil price worldwide, the margin of oil-refining has declined since, which consumes fresh water and drain waste water enormously. Being short of water resource increasingly, it has been focused to make economical use of water. This thesis contrasted domestic water-saving situation to other countries nowadays, analyzed in detail the water-using condition in HuaBei Petro-Chemical Company, and provided a comprehensive evaluation for this company. During the analysis mentioned above, undertaking supply-chain ideas, the integrated optimization had been carried within the whole company after completing the water-balancing test. The evaluation fully considered the water-network relationship among plants, systems, and factories. It contained water demand-supply balance, hierarchical management and water recycling during oil-refining production. And extra analysis had been given upon key units within important plants which consume water. At last, it was given to how to realize a useful water-managing project.There are totally five chapters in this thesis:Chapter I introduced the latest global water shortness, especially the situation and managing level of water-using in petro-chemical industry overseas.Chapter II described mainly conditions on HuaBei Petro-chemical Company.Chapter III analyzed the present water-using state and relevant equipments.Chapter IV primarily offered optimized analysis and evaluation of water-consuming for oil-refining production based on data in hand. Solutions had also been given to the related problems.Chapter V eventually mentioned several suggestions on water-using and water-draining, given current producing and financing.
