example

[0106] Taking a delayed coking unit as an example, the description is as follows:

[0107] A delayed coking unit started construction in October 2007, and successfully started up in December 2009, producing qualified products. It uses the vacuum residue produced by the new 10 million tons / year atmospheric and vacuum device as raw material for secondary processing, with an annual processing capacity of 2.3 million tons of vacuum residue. The device covers an area of ​​210×117=24570m 2 , about 36.855 mu, is located on the west side of the tank area of ​​the Ministry of Aromatics, on the north side of the newly built 200,000 tons / year sulfur recovery unit, and on the south side of the newly built sewage treatment plant. The device is designed by Luoyang Petrochemical Engineering Company (LPEC), and adopts the current domestic advanced process of "flexibly adjustable cycle ratio".

[0108] The delayed coking unit is composed of process production and petroleum coke treatment, wh...

Abstract

The invention discloses a process simulation software based online calibration system. After a Web application module receives instructions of a client Web browser, a data acquisition module is started to acquire data, and acquired data are subjected to reconciliation through a data reconciliation module and then transmitted to an analog computation module; the analog computation module starts a calibration simulation model and outputs a result to a template engine module after analog computation is finished; the template engine module updates the result to a calibration report template to create a new calibration report; the Web application module returns the new calibration report to the client Web browser. The process simulation software based online calibration system has advantages that automatic online calibration in a production process is realized, and manual operations of data recording, statistics and analysis and report writing are replaced; a calibration report generation period is greatly shortened from several weeks to a few minutes, basic data representing operating conditions in the production process can be timely provided for technical personnel, and the basis isprovided for technical measure improvement.

Description

technical field [0001] The invention relates to an online calibration method for a production process. In particular, it relates to an online calibration system based on process simulation software. Background technique [0002] Process simulation is a comprehensive application of theories and methods of process control, system engineering, mathematical calculation and other disciplines. It is a technology to describe the unit process, equipment and the entire process system in the chemical industry and other industries with computers. This technology includes static simulation and dynamic simulation. It can not only calculate material balance, heat balance, phase balance and other calculations for chemical processes, but also predict the impact of operating variable changes on process technology. This technology is the product of the integration of engineering technology and computer technology. With the development of computer technology, it provides a fast and efficient ...
