Analysis of Sulfur Recovery Unit (SRU) Refinery as Sulfur Emission Control Unit at PT X, Indonesia

Abstract

PT X is an Indonesian oil and gas processing industry. Recognizing the potential harm posed by gas emissions from oil and natural gas processing, PT X is actively working to control air pollution. One of their initiatives involves the construction of a Sulfur Recovery Unit (SRU) refinery to reduce sulfur gas emissions, particularly from H2S, by converting them into liquid sulfur products. The SRU refinery effectively processes approximately 73% of the H2S gas emitted during production. In January 2023, air quality measurements were conducted on stack 94-F-403 SRU, revealing the following results: the average concentration of SO2 emissions was 14.69 mg/m3, and the average concentration of NO2 emissions was 3.04 mg/m3. These measurements indicate that both parameters fall below the quality standards set by the Indonesian Minister of Environment Regulation No. 13 of 2009, which defines acceptable emission limits for the oil and gas industry. Based on these findings, it can be concluded that the emissions from stack 94-F-403 SRU are classified as non-polluting, adhering to the Indonesian government's quality standards. PT X's commitment to environmental responsibility is evident through their implementation of the SRU refinery, which significantly reduces gas emissions and ensures compliance with regulatory requirements.
