Optimization method for anti-corrosion measures for petroleum and natural gas industrial device

Abstract

The invention discloses an optimization method for anti-corrosion measures for a petroleum and natural gas industrial device. The optimization method comprises the following steps: optimizing material anti-corrosion measures, reasonably determining materials of key corroded parts between equipment and a pipeline according to the content of corrosive mediums in process mediums of the device, corrosive damage manners of the corrosive mediums to the equipment and the pipeline and an actual corrosion rate threshold value; optimizing process anti-corrosion measures, carrying out standard process operation according to real-time monitoring of the key corroded parts of the device, enhancing the sampling analysis to the corrosive mediums, effectively controlling the processing quality of the process mediums, and efficiently utilizing a corrosion inhibitor; optimizing corrosion detection measures, and finishing the setting of the number and positions of online corrosion rate monitoring points on the key corroded parts of the equipment and the pipeline and setting of the number and positions of offline fixed point thickness measurement points; concluding and analyzing corrosion failure cases, establishing a corrosion failure case database, and carrying out conclusion and analysis, thereby guaranteeing the smooth operation of the petroleum and natural gas industrial device.

Description

technical field [0001] The invention relates to the field of oil and natural gas industry, in particular to an optimization method for anti-corrosion measures of oil and natural gas industrial equipment. Background technique [0002] With the increasing shortage of energy, the mining and processing of high-sulfur or high-acid low-quality crude oil and the development and utilization of sour natural gas have become the benefit growth point and development trend of my country's oil and gas industry. However, these low-quality raw materials contain rich chloride , Sulfide, inorganic salt, naphthenic acid, nitride, hydrogen sulfide, carbon dioxide, oxygen and other corrosive media, so that oil and gas industry production equipment such as refining and chemical equipment and high-sulfur natural gas purification equipment face huge corrosion risks. Moreover, with the continuous deepening of mining, processing or development and utilization, the properties of raw materials will cont...
