Faced with the problem of high gas cleaning (H2S removal)costs, resulting in high power generation costs using gas engines, we evaluated some 26 different systems. Finally we narrowed down to 4 systems with the potential for low gas cleaning costs. We have now tried out one system which removes...

Gordonba - you posted something on the 'waste to power' thread......but nothing appeared on the screen. Could you post it again, please? Thanks. atulbhalla46@hotmail.com

The condensates are a mixture of 'tars' and the best way to get rid of tars, as Gordonba suggests, is to first know what is contained (at least the major fractions). The answer lies not in the scrubbing, but in the elimination of tars. Higher temperatures and a control on the residence time is...

You need to address some basic questions first: 1. What is the composition and amount of waste to be processed on a continuous basis....this gives you the lead to plant capacity and equipment types. 2. What are the local norms (if any) for emissions in addition to any country wide norms. 3...

In answer to Randolph's Q of 22 June 2001........u must have got the answer by now but I thought I might share with u that US Peroxide has a fair amount of info on dosing rates...look at their website. comparisons with other chemicals is also listed.

Randolph: (or whoever is answering.......I get a bit confused about this).....the flow rates for this specific case are given below. However, there are many such systems with somewhat similar capacities, so we are looking for a generic solution to a major problem facing the Indian environmental...

KARENEUGENIA....... Yes, we have an interest in knowing how much to dose chemicals in order to either suppress H2S formation or control of pH etc in the scrubbing functions where H2s removal is being attempted. At this stage I can give only preliminary design requirements, but please feel free...
