  • PROCESS FOR PRODUCING AMMONIUM THIOSULFATE FROM ANAEROBIC DIGESTATE
    Publication number: 20240166570
    Abstract: A process for producing ammonium thiosulfate from anaerobic digestate. The process involves injecting sulfur dioxide or ammonium bisulfite into a column containing liquid digestate and biogas to produce a sulfite solution. The sulfite solution further reacts with hydrogen sulfide entrained in the biogas and the digestate to produce commercially desirable ammonium thiosulfate and sweet biogas.

  • PROCESS FOR PRODUCING AN AMMONIUM SULFITE AND BISULFITE SOLUTION FROM AMMONIA GAS
    Publication number: 20240124318
    Abstract: A process for producing ammonium sulfite and ammonium bisulfite from an ammonia gas stream. The process involves injected sulfur dioxide into a circulating liquid stream to an optimal pH that captures gaseous ammonia from a gas stream. The captured ammonia reacts with sulfur dioxide and water to form the desired products.

  • PROCESS FOR ELIMINATING HYDROGEN SULFIDE IN AN AMMONIUM SULFATE SOLUTION
    Publication number: 20240042381
    Abstract: A process for substantially removing hydrogen sulfide from an ammonium sulfate solution. The process involves maintaining the pH of the solution to a range that optimally removes entrained hydrogen sulfide. The hydrogen sulfide is then reacted with sulfites, bisulfites, or sulfur dioxide to form ammonium thiosulfate.
