Embodiment 1

[0026] The standardized water analysis method applicable to petroleum refineries provided by this application includes the following steps:

[0027] (1) Analyze the water type of each unit: Through process analysis, sort out the water type of each refinery unit, including fresh water, circulating water, desalinated water, deaerated water, condensed water, reclaimed water, purified water, sulfur-containing sewage, steam wait.

[0028] The atmospheric and vacuum device used in this example is a general term for the two devices of atmospheric distillation and vacuum distillation, and its operation mainly includes three processes: desalination and dehydration of crude oil, atmospheric distillation, and vacuum distillation.

[0029] The No. 3 atmospheric and vacuum distillation unit of Zhenhai Refining and Chemical Branch of China Petroleum & Chemical Corporation processed 8,482,205 tons of crude oil in 2015 (that is, 8,482,205 tons). The main water links include: circulating wate...

Embodiment 2

[0038] The values ​​of the conversion coefficients for various types of water are the same as in Example 1.

[0039] The No. 2 atmospheric and vacuum distillation unit of Zhenhai Refining and Chemical Branch of China Petroleum & Chemical Corporation processed 5,872,735 tons of crude oil in 2015. The circulating water is mainly used for the cooling of air coolers, fans, cooling equipment, pumps and other equipment and materials in the device; the purified water is mainly reused for electric desalination water injection, and can also be used for three-top water injection and drug preparation water; desalinated water can be used Water injection in three tops, wet air-cooling spray, pump end seal, water seal tank replenishment and chemical preparation; deoxygenated water is used for boiler and steam drum steam generation; fresh water is used for domestic water, water for hand washing and eye washing, ground flushing water, etc. On the one hand; sulfur-containing sewage can be reus...

Abstract

The present application provides a method for determining the unit water consumption of a petroleum refining unit, which includes the following steps: 1) obtaining the type of water used by the petroleum refining unit; 2) using different types of water used by the petroleum refining unit 3) the sum of the converted water consumption of different types of water used by the petroleum refinery is divided by the water consumption of the petroleum refinery The processing quality of the raw materials under the sum of the water consumption is used to obtain the unit water consumption of the petroleum refining device.

Description

technical field [0001] This application provides a method for determining the unit water consumption of a petroleum refinery unit. Background technique [0002] The current situation of China's water resources can be simply summarized as the shortage of water resources and serious water pollution. At present, more than 40% of China's population lives in water-scarce areas, and more than 400 cities are short of water, of which 108 are severely short of water, affecting more than 160 million urban residents. Protecting water resources and saving water resources is a major issue facing the country and industrial enterprises at present. Water saving is not only to reduce water consumption, but more importantly, to use water resources more effectively, manage water resources more scientifically, and follow the path of "water-saving development" the way. Since 2012, the "Opinions on Implementing the Strict Water Resources Management System" (Guo Fa [2012] No. 3), "Assessment Mea...
