Abstract

The invention discloses a method for carrying out quantitative evaluation on desulfurization energy efficiency of high-sulfur natural gas. The method comprises the following steps: firstly establishing a desulfurization energy efficiency evaluation system, determining main controlling factors, selecting a purified gas yield, desulfurization energy consumption and desulfurization selectivity as evaluation indexes, and determining a weighted value of each evaluation index; calculating or measuring an actual value of each evaluation index, setting a satisfaction value and an un-allowance value of each evaluation index, and carrying out comparison to solve a single effect coefficient of each evaluation index; and finally carrying out overall quantitative evaluation on the desulfurization energy efficiency according to the weighted value and single effect coefficient value of each evaluation index. By adopting the method for carrying out quantitative evaluation on desulfurization energy efficiency of high-sulfur natural gas, quantitative analysis is carried out on the desulfurization energy efficiency of the high-sulfur natural gas through calculation, so that technicians in the technical field can judge the desulfurization energy efficiency more quantitatively, clearly, visually and correctly.

Description

technical field [0001] The invention relates to a natural gas desulfurization process, in particular to a quantitative analysis method for desulfurization energy efficiency of high-sulfur natural gas. Background technique [0002] High-sulfur natural gas is rich in a large amount of H 2 S, CO 2 Such acidic components usually need to greatly increase the circulation of desulfurization solution to meet strict purification requirements, which leads to several times to more than ten times the energy consumption of gas purification compared with conventional natural gas. The product gas yield after purification of high-sulfur natural gas is much lower than that of conventional natural gas, mainly because a large amount of acid gas is removed. Based on the above two characteristics, it is required to pay great attention to energy saving and consumption reduction and increase product gas yield in the purification of high-sulfur natural gas, so as to improve the economic benefits ...
