Absorption, or gas absorption, is a unit operation used in the chemical industries to separate gases by washing or scrubbing a gas mixture with a suitable liquid. Gas absorption is usually carried out in vertical countercurrent columns The solvent is fed in at the top of the absorber, the gas mixture from the bottom. We developed the process to get high yield and high efficiency.

A gas processing furnace according to the present invention includes: a heater body filled with an electric heating element; and a tubular gas passage passing through the heater body. The gas processing furnace includes: a block-like heater body extending in the up-down direction and filled with the electric heating element; gas passages passing through the heater body in the up-down direction, the gas passages being consecutively disposed or extended in the front-back direction, the gas passages being arranged so as to form a plurality of arrays parallel to each other in the right-left direction, in a plan view; and a headbox mounted at an upper end portion of the heater body and configured to allow the gas passages to communicate with each other via a communication space formed inside the headbox.

A hydro-active scrubber and reactor (HSR) system and apparatus is disclosed that includes a main body, an inlet configured to receive a first fluid medium comprised of pollutant particles, and a nozzle configured to dispense a second fluid medium within the main body. In addition, the HSR system and apparatus may also include a cylindrical body or hydro-vortex generator within the main body having a plurality of horizontally positioned rods projecting therefrom, wherein the cylindrical body further comprises a plurality of openings. Further, the HSR system and apparatus can include a motor configured to rotate the cylindrical body thereby directing the first and second fluid mediums through the cylindrical body. In addition, a first area within the main body can receive the pollutant particles from the first fluid medium, and a first outlet within the main body can be configured to direct the received pollutant particles out of the main body.

This exhaust gas processing equipment is provided with an exhaust line through which exhaust gas discharged from a boiler circulates, a carbon dioxide recovering device for recovering carbon dioxide included in the exhaust gas, and an exhaust gas heating device provided downstream of the carbon dioxide recovering device to heat the exhaust gas. The carbon dioxide recovering device includes a first medium line through which a first medium circulates, and a second medium line through which a second medium higher in temperature than the first medium circulates. The exhaust gas heating device includes a first heating unit for heating the exhaust gas by means of heat exchange with the first medium, and a second heating unit for heating the exhaust gas passing through the first heating unit even more by heat exchange with the second medium.

A mobile gas processing plant includes an inlet and an outlet, first and second Joule-Thompson (JT) valve units, an inlet scrubber, a dehydration unit including a contact tower, inlet and outlet filter separators, a vertical separator, and a dual pass line heater including first and second heating coils. The mobile gas processing plant is a mobile unit that is permanently mounted on at least one transport. The dehydration unit includes a contact tower that is permanently mounted on the at least one transport such that the contact tower is rotated up to be in an upright position relative to a base frame of the transport in an operational mode, and the contact tower is rotated down to be in a prostrated position relative to the base frame in a transportation mode. Each of the first and second JT valve units includes a first JT valve and a second JT valve. In the operational mode, and for each of the first and second JT valve units, a hydrocarbon gas stream flows through one of the first and second JT valves operating as a primary valve, and does not flow through the other of the first and second JT valves operating as a backup valve.
