Mikroorganisme memiliki peranan penting di dalam proses pengolahan secara


biologi seperti Bio-Sulphur Recovery. Dalam hal ini konsorsium Thiobacillus


digunakan sebagai agen biologis untuk mengubah H2S menjadi S0, selain H2S di


dalam gas alam terdapat pengotor lainnya yaitu benzene,toluene dan xylene yang


bersifat inhibitor bagi mikroba. Oleh karena itu diperlukan penelitian mengenai


pengaruh BTX terhadap agen biologis.


Penelitian ini bertujuan untuk menguji pengaruh BTX terhadap efisiensi Bio-


Sulphur Recovery dan menentukan nilai batas minimum dari konsentrasi BTX.


Percobaan dilakukan secara batch dan kontinyu dengan menggunakan biological


sulphur recovery unit (BSRU) skala laboratorium.


Kosentrasi benzene divariasikan pada 895,5 mg/l, 1791 mg/l dan 3582 mg/l;


toluene divariasikan pada 267,5 mg/l, 535 mg/l dan 1070 mg/l; xylene


divariasikan pada 73 mg/l, 146 mg/l dan 292 mg/l. Toluene dan xylene lebih


bersifat inhibitor di dalam pertumbuhan konsorsium Thiobacillus dibandingan


benzene.

Deskripsi Alternatif :

Microorganisms have an important role in biological processing such as Bio-


Sulfur Recovery. In this case the Thiobacillus consortium is used as a biological


agent to convert H2S into S0, in addition to H2S in natural gas there are other


impurities that are inhibitors of benzene, toluene and xylene for microbes.


Therefore, research on the effect of BTX on biological agents is needed.


This study aims to examine the effect of BTX on the efficiency of Bio-Sulfur


Recovery and determine the minimum limit value of BTX concentration. The


experiments were conducted batch and continuous using a laboratory-scale


biological sulphur recovery unit (BSRU).


Benzene concentrations were varied at 895.5 mg / l, 1791 mg / l and 3582 mg / l;


toluene was varied at 267.5 mg / l, 535 mg / l and 1070 mg / l; xylene was varied


at 73 mg / l, 146 mg / l and 292 mg / l. Toluene and xylene are more inhibitors in


the Thiobacillus consortium growth than benzene.
