摘要： A process for treating a gas comprising hydrogen sulfide and carbon dioxide (1) by contacting the gas with a scrub solution comprising ammonium sulfite and ammonium bisulfite (2) in a first contact zone (3) to produce ammonium thiosulfate. The scrub solution can be formed in a second contact zone (6) by contacting ammonia (8) and sulfur dioxide (7) with an aqueous solution. The oxidation potential of the first contact zone effluent liquid can be controlled by modulating the amount of sulfur dioxide supplied to the second contact zone. Alternatively, the sulfite concentration of the first contact zone effluent can be measured with an infra-red analyzer and the amount of sulfur dioxide supplied to the second contact zone is modulated in response. Additionally, the amount of ammonia supplied to the second contact zone can be modulated in response to the pH in the second contact zone.

摘要： Systems and processes for improving quality and yield of one or more distillate products generated in a distillation column are disclosed. The system comprises a feed inlet distributor that reduces the amount of liquid entrained in vapor rising from the feed zone of the distillation column, a wash zone collection apparatus having an improved design for collecting slop wax falling from a liquid/vapor contacting structure provided in the wash zone, a recirculation subsystem for recirculating at least a portion of the collected slop wax to the top of the wash zone for distribution as wash oil, and a control subsystem. The feed inlet distributor ensures a horizontal fluid flow path free of transverse surfaces thereby minimizing atomization of liquid droplets entrained in vapor in the feed stream.

摘要： Processes for selectively eliminating hydrogen sulfide from liquid ammonia, either anhydrous or aqueous, are described herein. The processes generally include contacting a first liquid stream, anhydrous or aqueous, comprising ammonia and hydrogen sulfide, with a solution comprising sulfur dioxide to convert the hydrogen sulfide to thiosulfate.
