Abstract: A method (200) for desulfurization of a flue gas in a desulfurization unit of an industrial plant, includes receiving (202) a plurality of baseline parameters corresponding to the desulfurization unit of the industrial plant. The method further includes measuring (204), using a stack sensor, an emission value of sulfur oxides in the flue gas. The method also includes estimating (208), using a controller, a desirable value of a slurry parameter for desulfurization of the flue gas based on the measured emission value of the sulfur oxides. The method further includes determining (208), using the controller, at least one desulfurization parameter based on the desirable value of the slurry parameter. The method also includes controlling (210), using the controller, operation of the desulfurization unit based on the at least one desulfurization parameter to modify consumption of at least one of a slurry and an auxiliary power in the industrial plant.

Abstract: A method for removing NOx from flue gas by SCR includes supplying a reagent for the SCR reaction of NOx into the flue gas, then contacting the flue gas with a catalyst. Supplying the reagent includes supplying a less than stoichiometric amount of reagent, and after contacting the flue gas with a catalyst a final NOx removal step is provided.

Abstract: A rotating packed bed RPB that includes a first and second packed bed both arranged on the same rotatable shaft. A gas is directed via a gas inlet through the first packed bed in co-current flow with a liquid in a radially outward direction towards the outer radius of the packed bed. The liquid enters the first packed bed via a first liquid inlet. The gas exiting the first packed bed is directed to the second packed bed and forced through it in a radially inward direction in counter-current flow with a liquid, which enters through a second liquid inlet. The arrangement allows an operation of the rotating packed bed with less energy compared to RPBs of the prior art operating in counter-current flow only. The apparatus allows low-cost design and high design flexibility.

Abstract: The present disclosure relates to a method of operating a boiler system that includes an oxyfuel boiler in which an oxygen stream and a fuel stream are combusted to generate a stream of flue gas, an oxygen gas source producing the stream of oxygen for the boiler, and a gas processing unit for cleaning and compressing at least a portion of the stream of flue gas generated in the boiler for producing a stream of pressurized fluid comprising carbon dioxide. The method includes operating the boiler system, at least for a period of time, in an evaporation mode, in which a stream of oxygen from the oxygen gas source in liquid form is evaporated prior to being introduced in the boiler by transferring heat energy to the stream of liquid oxygen from a first stream of carbon dioxide of the gas processing unit. The present disclosure further relates to a boiler system for an oxy-fuel process as well as to a power plant comprising such a system.

Abstract: A process and a system for the solution mining of evaporites and preparation of the obtained saline solution and in particular for the dissolution of salts, evaporation and cooling of the obtained saline solution, and crystallization of salts under subtropical and tropical climatic conditions. The invention can also be applied for the preparation of naturally occurring saline solutions. In the process and system of the invention, a solvent is heated in a solar pond by means of solar energy to a temperature above ambient condition and up to approximately 60.degree. C. to 80.degree. C. The heated solvent is introduced into a cavern to be solution mined to produce a production brine which is heated. The heated production brine leaves the cavern and is then cooled along with water evaporation whereby solids crystallize and separate producing a solid product and a cold mother solution.
