The Project Of Jinzhou Petrochenmical's Petrol And Diesel On-line Blending System Construction And Implementation

With the continuous progress of production technology and increasing product quality requirements, in the refinery oil blending process, traditional way of artificial blending to can't meet the demand of production and economic benefit. Oil on-line blending device being used by more and more refineries, became the main direction of oil blending.On-line blending device is feasible and can improve the refinery profits, the company developed on-line blending optimizing system has been applied to various refinery, smooth operation, high reliability. The project in combination with the practical demand of Jinzhou Petrochemical Company, the development of the blending system will bring considerable economic benefits for the company.In this paper mainly discusses the Jinzhou Petrochemical on-line blending device USES is the Ganges online company oil blending system of project construction process, and mainly introduced from the following aspects: first, introduce the project background, current situation and problems of production; Put forward the construction of a petrol and diesel blending online project can be done well production optimization, and on-line blending system requirements analysis. And then to Yokogawa online optimizing blending system adopted in the project's overall design, system structure, system configuration. And focus on petrol and diesel blending system characteristics and functions, this paper mainly introduces the contract management, quality control of blending and optimize blending control core software. The last tank farm monitoring system is introduced in this paper, and the reliability of the whole project system implementation.The system automatic control level is high, high control accuracy and precision in real time, high reliability, strong expansibility, and briefly introduces the usage, optimization, used to make the system flexible.
