Problems solved by technology

Since the heat exchanger is installed on the multi-way branch pipe downstream of the main pipe, there must be a biased flow phenomenon after the oil and gas enter the multi-way branch pipe from the main pipe. If water and agent are injected into the main pipe, some heat exchangers will be insufficiently watered and injected due to the biased flow. As a result, the problem of corrosion leakage in the internal tube bundle or outlet elbow of the heat exchanger is caused

Abstract

The invention relates to a method of preventing corrosion of pipe bundles in a heat exchanger and at an outlet of the heat exchanger for preventing corrosion and leakage of the pipe bundles in the heat exchanger and at the outlet of the heat exchanger, and belongs to anti-corrosion measures of heat exchangers in petroleum and chemical devices. In particular, water and an agent are injected to an oil and gas pipeline in front of the heat exchangers of multiple branched pipelines.

Description

【Technical field】 [0001] The invention relates to a method for injecting water and neutralizing agent on the oil and gas pipeline at the front inlet of the heat exchanger, which is used to prevent corrosion and leakage of the tube bundle inside and at the outlet of the heat exchanger, and belongs to the oil and chemical equipment. The anti-corrosion measures of the heat exchanger are specifically to inject water and injection agent on the oil and gas pipeline before the heat exchanger of the multi-way branch pipeline. 【Background technique】 [0002] In existing refining and chemical plants, the high-temperature gas phase medium produced by fractionation equipment needs to be cooled and recovered through heat exchangers. For example, in the atmospheric and vacuum unit, the high-temperature oil and gas separated from the crude oil through the fractionation tower needs to be cooled by a heat exchanger, and then recovered in the subsequent unit. However, high temperature oil an...
