HIGH HYDROGEN SULFIDE CONTENT AND REDUCTION OF METHANE CONTENT IN AD

Asked December 3, 2017, 11:24 AM EST

We are a mexican company located in a place named as La Laguna in the states of Durango and Coahuila.

We finished the construction of an AD in Mexico one year ago, we desgined it and we built it. We installed a 2 MW Cummins power genset and we are almost ready to start producing electricity. However, this week the content of Methane reduced from 58%to only 34% and Hydrogen Sulfide grew from 50 ppm to 3,352 ppm.

In order to clean the gas from the Hydrogen Sulfide we use an AWITE oxygen system. This system injects air in the AD to produce the oxidation of the Hydrogen Sulfide. But now we have 9.03% of O2, we never had this ammount of O2 in the gas composition.

Please visit the following link to know what we built. We will process 500 tons of fresh cow manure per day. We built 14 tanks of 1,500 m3 each one.



WE WILL STRONGLY APPRECIATE ANY ADVISE YOU MAY GIVE US, WE ARE REALLY WORRIED ABOUT THIS PROBLEM, EVERYTHING IS READY TO PRODUCE ELECTRICITY AND WE DO NOT HAVE THE RIGHT GAS, KINDLY I ASK YOU FOR YOUR HELP.

Troubleshooting something like this is difficult via email. We recommend that you look for a consulting engineer who can do a site visit and spend the time viewing your data needed to adequately assess the situation.
