Impregnated Molecular sieve (Sulabead®) instead of active carbons, which means lower maintenance and transportation costs
Production cost low due to the regeneration of Sulabead®
Low carbon foot print due to absence of extremely polluting active carbon
No water required nor wasted water to clean Drain water is used for production of Sulphuric acid (H2SO4)
At high H2S concentrations the acid production will be profitable
The complete process is liquid glycol cooled to obtain highest efficiency
The heat from the chiller can be used for district heating and is higher than the electrical power consumed due to condensation heat of the drainwater
Low power consumption Maintenance costs are low due to the long life to the adsorbent and compressor
Due to intensive water removal upstream – no aggressive liquid acids: H2CO3 and H2SO3 – and water-cooled oil cooler, there is a long oil change interval
The production costs are low due to absence of wastewater or coal
For maintenance shut down CO2 is used as a safety gas instead of Nitrogen for two reasons: CO2 is ample available and keeps smoke gas free from Nitrogen impurities
