Oil-refining chemical production balancing system

Abstract

The invention relates to an oil-refining chemical production balancing system, which comprises an oil-refining production device, an oil tank, a lateral line for connecting the oil-refining production device and the oil tank, and a data acquisition unit for connecting an oil tank volume data acquisition device and a lateral line flow conjecture data acquisition device, wherein the data acquisition unit is connected with an estimation calculating device which can calculate out lateral line flow conjecture data according with oil tank volume data. The oil-refining chemical production balancing system can calculate out the lateral line flow conjecture data which are in consistent with the oil tank volume data and accords with actual situations better through the oil tank volume data, so thata production manager can accurately know the production condition of the oil-refining production device. The oil-refining chemical production balancing system can feed back on-site production information in time and make adjustments according with the actual situation aiming at the production condition of the device.

Description

technical field [0001] The invention relates to a process monitoring system for oil refinery and chemical industry, in particular to a balance system for oil refinery and chemical industry production. Background technique [0002] The traditional production process of refining and chemical industry is: the dispatching department decomposes the monthly production plan into an executable short-cycle production scheduling plan based on the monthly production plan formulated by the planning department, comprehensively considering the production status of crude oil, equipment, tank farms, etc. and market sales information (Usually one week or five days), and arrange the production according to this, and issue the production plan to the processing equipment and production auxiliary units. The production balance of refining and chemical enterprises refers to the collection of device side line flow data, device quality data of incoming and outgoing materials and related tank storage...

AI Technical Summary

Problems solved by technology

In the past, due to the lack of timely feedback of on-site production information, the command of the dispatch to the production of the enterprise lagged behind, and it was impossible to make realistic adjustments to the production status of the device

[0003] At the same time, my country's refineries have different measurement conditions for the sideline flow of refinery production units. Some refineries have better measurement conditions, and some refineries have poorer measurement conditions. In particular, some old refineries lack measurement methods or use low-precision Measuring instruments such as "orifice plates", the measurement results of these flow instruments are often very different from the actual receiving volume of the oil tank, so that the production management personnel cannot accurately understand the production situation of the refining production unit
