Refining production process optimal analysis method and system

Abstract

The invention provides refining production process optimal analysis method and system. The method comprises the following steps that: receiving refining initial parameters input by users, such as parameters of all refining production devices, parameters between devices, refining process parameters and technical operation parameters; invoking fundamental data corresponding to the refining initial parameters; starting the corresponding model in a process simulation model library according to the refining initial parameters and the fundamental data, and generating the key parameter of the refining production process; comparing the key parameter with the optimal parameter and best practical value in an expert knowledge base, and generating a comparison result; and outputting the comparison result to users. Through the invention, the multi-variable optimal problem caused by the complex energy-material relation in the refining production process can be effectively solved; the energy-utilization reasonableness of the refining production process, the production devices, and main energy-utilization equipment can be judged; the potential point of improving the energy efficiency can be found; and a quantificational optimization scheme is finally obtained.

Description

technical field [0001] The present invention relates to petroleum refining technology, in particular to a refining and chemical production process optimization analysis method and system. Background technique [0002] Energy is the driving force behind economic development and an important material basis for human survival and development. With the rapid development of my country's national economy, problems such as energy shortage and low utilization rate have seriously restricted the development of the national economy and the improvement of people's living standards. In 2010, my country's net import of crude oil was 239 million tons, and the dependence on foreign crude oil exceeded 55%. According to the statistical results of the National Bureau of Statistics, my country's total energy consumption in 2010 was 3.25 billion tons of standard coal, and the national energy consumption per 10,000 yuan of GDP decreased by 4.01% compared with the same period in 2009, but there i...
