Estimation and Reduction of Methane Emissions at the Scheduled and Repair Outages of Gas-Compressor Units

Abstract

Assessment of the negative impact on the components of the natural environment during the scheduled and repair outages of gas-compressor units in transportation the process of the natural gas was the purpose of the performed scientific work. The results of the monitoring studies, in which the methane concentrations were measured in the atmospheric air near the source of pollution and on the border of the sanitary protection zone during volley emissions of natural gas into the atmosphere, are presented in the article. In addition, a method that eliminates the release of the natural gas into the atmosphere during the scheduled and repair outages of gas-compressor units are suggested in the article. The method is based on the redistribution of gas flows and the direction of natural gas to the gas distribution station. Volley emissions of methane into the atmosphere will completely eliminated as a result of implementing this method. The proposed technical solution is aimed at reducing the negative impact on atmospheric air near gas compressor stations. Moreover, the proposed method is able to minimize the economic damage to gas companies because of the loss of marketable products.

Community Health Impacts From Natural Gas Pipeline Compressor Stations

“…Natural gas compressor stations emit a variety of airborne pollutants (D. R. Brown et al., 2015 ; Green & Crouch, 2021 ; Hendryx & Luo, 2020 ; Johnson et al., 2015 ; Olaguer, 2012 ; Russo & Carpenter, 2017 ; Strizhenok & Korelskiy, 2019 ; van der A et al., 2020 ; Walter, 2020 ; White et al., 2019 ). Compressor stations can have a significant effect on local air quality; in some rural environments, emissions from compressor stations can account for 98%–99% of VOC ozone precursors and 57%–61% of NO x ozone precursors (Adgate et al., 2014 ).…”

“…Compressor stations are also significant sources of methane, a potent greenhouse gas and contributor to global warming (Strizhenok & Korelskiy, 2019 ). The majority of the methane is emitted during blowdowns, when compressor units are depressurized for maintenance and release large amounts of high‐pressure gas to the atmosphere (White et al., 2019 ).…”

Production of biodiesel fuel from vegetable raw materials

“…The second common method of biodiesel production consists of the transesterification of vegetable oils [22], a reaction of the interaction of triglycerides with alcohol leading to the formation of esters and glycerol (Fig. 3) [23][24][25].…”
