Abstract: A subsea pump system is adapted to close a hydraulic ram of a blowout preventer. The subsea pump system has at least a first pump (210) and a second pump (220) configured to pump drive fluid from a source to the hydraulic ram. The system has a controller (230) configured to automatically select at least one of the first and second pumps for pumping the drive fluid wherein at least the first pump(210)is selected at a lower fluid pressure range and at least the second pump(220) is selected at a higher fluid pressure range.A method of operating a pump system and an intervention skid for a pump system are also described.

Abstract: In the desulfurization of flue gas and the like, the gas is preliminarily treated to remove sulfur trioxide and sulfuric acid by a first cooling of the gas, e.g. to about 250 DEG F to 400 DEG F in a combustion air preheater (14), and then simultaneously or thereafter introducing an aqueous stream (18) from an FGD system (20) containing dissolved chloride, said aqueous stream (18) being completely vaporized upon injection (22) into said gas, and recovering from the gas chloride salts which remain in the gas after the water fraction of the aqueous stream has been vaporized, and ammonium chloride which precipitates upon the fly ash in the gas or forms a finely-divided suspension. Ammonia may be added (16) to react with at least some of the Cl values contained in the flue gas if further reduction of the chloride in the FGD system (20) is desired.
