| Summary: | 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. |
