Common technical and economic indicators for oil refining
In addition to evaluating product quality indicators, the quality of the oil refining process needs to be evaluated by technical and economic indicators. Economic and technical indicators are the general term for indicators that indicate the degree of utilization of raw materials, fuels, power, etc., and reflect the level of production technology and economic benefits.
The main technical and economic indicators commonly used in oil refining are as follows:
Refining rate
Refining rate refers to the percentage of refined oil quality in crude oil quality.
The calculation method is as follows:
Refining rate (%) = product oil quality / crude oil quality × 100
Refining consumption
Refining consumption refers to the percentage of the quality of crude oil lost before and after refining to the quality of crude oil, that is, the ratio of the difference between the quality of crude oil and refined product oil to the quality of crude oil.
The calculation method is as follows:
Refining consumption (%) = (crude oil quality-product oil quality) / crude oil quality × 100 = 100-refining rate (%)
Acid value refining consumption ratio
The acid value refining consumption ratio refers to the percentage of refining consumption produced by reducing the unit acid value before and after refining, and is used to express it in the form of ratio.
The calculation method is as follows:
Acid price refining consumption ratio=1: refining consumption (%)/(acid price of crude oil-acid price of refined oil)
Refining Index
The refining index refers to the percentage of refining consumption for every 1% of free fatty acid (FFA) removed before and after refining.
The calculation method is as follows:
Refining index = refining consumption (%)/[crude oil FFA (%)-refined oil FFA (%)]
Refining efficiency
Refining efficiency refers to the percentage of the quality of refined oil in the quality of neutral oil in crude oil.
The calculation method is as follows:
Refining efficiency (%)=quality of refined oil/quality of neutral crude oil×100=quality of refined oil/quality of crude oil (1-impurity%)×100
Coal consumption
Coal consumption refers to the kilograms of standard coal used to refine 1000kg of crude oil.
The calculation method is as follows:
Coal consumption (kg/1000kg) = standard coal consumption (kg) / crude oil quality (1000kg)
Power consumption
Power consumption refers to the degree of electricity used to refine 1000kg of crude oil.
The calculation method is as follows:
Electricity consumption (kW·h/1000kg)=Power consumption (kW·h)/Crude oil quality (1000kg)
Steam consumption
Steam consumption refers to the kilograms of water vapor used to refine 1000kg of crude oil.
The calculation method is as follows:
Steam consumption (kg/1000kg) = steam consumption (kg) / crude oil quality (1000kg)
Water consumption
Water consumption refers to the kilograms of water used to refine 1000kg of crude oil.
The calculation method is as follows:
Water consumption (kg/1000kg) = water consumption (kg) / crude oil quality (1000kg)
