Microorganisms have an important role in biological processing such as Bio- <br /> <br /> <br /> Sulfur Recovery. In this case the Thiobacillus consortium is used as a biological <br /> <br /> <br /> agent to convert H2S into S0, in addition to H2S in natural gas there are other <br /> <br /> <br /> impurities that are inhibitors of benzene, toluene and xylene for microbes. <br /> <br /> <br /> Therefore, research on the effect of BTX on biological agents is needed. <br /> <br /> <br /> This study aims to examine the effect of BTX on the efficiency of Bio-Sulfur <br /> <br /> <br /> Recovery and determine the minimum limit value of BTX concentration. The <br /> <br /> <br /> experiments were conducted batch and continuous using a laboratory-scale <br /> <br /> <br /> biological sulphur recovery unit (BSRU). <br /> <br /> <br /> Benzene concentrations were varied at 895.5 mg / l, 1791 mg / l and 3582 mg / l; <br /> <br /> <br /> toluene was varied at 267.5 mg / l, 535 mg / l and 1070 mg / l; xylene was varied <br /> <br /> <br /> at 73 mg / l, 146 mg / l and 292 mg / l. Toluene and xylene are more inhibitors in <br /> <br /> <br /> the Thiobacillus consortium growth than benzene.
