Abstract: A method and system for transporting and processing sour gas are provided. The method includes collecting a sour gas at a collection location, which has an associated sweetening device, and delivering a solvent to the sweetening device from a regeneration device remote therefrom. The sour gas is treated at the collection location with the solvent in the associated sweetening device to form a sweetened gas and a sour gas-rich solvent. The sweetened gas is transported from the sweetening device to a gas processing plant remote therefrom, and the sour gas-rich solvent from the sweetening device is delivered to the regeneration device for regeneration therein.

Abstract: A chemical solvent is utilized to preferentially remove CO2 from a H2S-rich acid gas stream, the acid gas stream being absorbed by the chemical solvent from a sour syngas stream. A chemical solvent such as alkanolamine is used in a unique process configuration to separate CO2 from the acid gas stream. The resulting acid gas is significantly higher in H2S concentration with a substantial quantity of CO2 being removed. The resulting CO2-rich gas is recovered at minimal pressure loss, and can be remixed with the resulting sweet syngas stream as a feed for a gas combustion turbine for increased power generation.

Abstract: A control system controls a lubricating oil dewaxing apparatus. The temperature of waxy oil flowing through the apparatus is controlled. A sequential plurality of temperature sensing means senses the temperature of the waxy oil. A Comparing Means determines an isothermal heat transfer zone corresponding to latent heat transfer wax crystallization. Temperature upstream of the isothermal zone is controlled to a selected chilling rate. Temperature downstream of the isothermal zone is controlled to a selected filtering temperature. The control system effects the growth of wax crystals of a uniform and moderate size for optimum filtering rate and oil content.
