The content of mercury impurities in GPP feed streams and their effect on secondary processing processes

This article presents an analysis of the mercury content in the feed streams of the pyrogas drying unit of shop No. 2 of ethylene production by Stavrolen, LLC. The effect of mercury-containing compounds in the production of raw materials for polymer synthesis has been investigated. The distribution of mercury content in raw materials and liquid pyrolysis products is presented using the example of 2022 and 2023. The study of the obtained data showed that the largest amount of mercury and mercury-containing compounds is present in heavy fractions, which underlines the need for strict control at the stage of processing and purification. The thesis is put forward about the need to give priority to the control of mercury content in raw materials and products at all stages of the technological process. The use of a systematic approach will not only reduce the likelihood of equipment failures, but also help avoid large financial losses caused by unplanned shutdowns and repairs. The potential risks that can lead to disruptions in the operation of industrial facilities are described. An analysis is given on the choice of an optimal mercury impurity removal system. A brief comparison between absorption and adsorption drying is pre-sented. It is argued that the development and implementation of standards in the Russian oil and gas industry for the control of mercury impurities will be one of the key factors to ensure its safety and productivity. This measure will reduce the threat to both production facilities and the environment, given the high toxicity and danger of mercury and its derivatives as pollutants.
