Abstract

The invention discloses an energy consumption prediction method of an air separation system. The energy consumption prediction method comprises the following steps that: energy consumption data of air separation units of different scales are acquired; the energy consumption data are fitted through using a least square method, such that a fitting equation indicating the relationship between the air separation units and air separation scales can be obtained; air separation unit power consumption is determined according to the fitting equation; the electric efficiencies Eta of the air separation units of different scales is calculated according to the air separation unit power consumption and technical power of the air separation units; the electric efficiency Eta 1 of an air separation unit can be determined according to the electric efficiencies Eta of the air separation units of different scales; the power consumption of each air separation unit in each air separation item can be calculated according to the electric efficiencies Eta 1 of the air separation units; and the energy consumption of the air separation system can be calculated according to the energy consumption of the air separation units in each air separation item. According to the energy consumption prediction method of the air separation system, fitted curves are combined with a model equation, and the fitted curves of the electric efficiencies can be obtained through using actually measured data, and therefore, accurate prediction and analysis of the energy consumption of the air separation system can be realized.

Description

technical field [0001] The invention relates to the technical field of air separation, in particular to a method for predicting energy consumption of an air separation system. Background technique [0002] At present, when metallurgical and chemical companies consider the construction scale of air separation projects, they require oxygen, nitrogen and argon products to meet their own production, and still need to have a surplus. The excess oxygen, nitrogen and argon products are usually shipped to the factory for sale. The construction scale of the air separation project is too large. Although the oxygen, nitrogen and argon products can obtain more profits, the initial investment and energy consumption of the construction of the air separation project will increase. How to quantitatively study the change of energy consumption with the scale of air separation projects, so as to determine the optimal construction scale of air separation projects according to market conditions,...
