| titleOfInvention | Elimination of hydrogen sulfide and carbon dioxide from natural gas by means of absorption with a sodium hydroxide solution and subsequent treatment with ammonium hydroxide and oxidation for producing ammonium sulfate and ammonium carbonate |
| abstract | The invention relates to an absorption process with a chemical reaction for collecting carbon dioxide and hydrogen sulfide from natural gas, concentrating the fuel and eliminating the source of corrosion produced by the hydrogen sulfide in addition to its bad smell, and initially producing sodium carbonate and sodium sulfide in order to transform them into ammonium carbonate and ammonium sulfate. The process is carried out in a horizontal absorber having a diameter of 15.5 cm, using an 8% sodium hydroxide solution as an absorption liquid, and two sections measuring a metre long. Each section has three rows of nozzles, one in the upper part and the other two on the sides, forming a 90° angle to the vertical. There is a 20 cm gap between each nozzle such that each section has 15 dispersion nozzles for the absorption liquid. The absorber has a 10 cm high channel for receiving products by means of openings in the lower part of the equipment for collecting the absorption liquid with the retained acid gases. Ammonium carbonate and ammonium sulfate are obtained as end sub-products, which are concentrated and separated by fractional crystallization, and are filtered and dried in order to then be put into bags. |
