Bischoff seawater process

Rakt-Hydro Seawater Process, 599 Bechtel Seawater Process, 600 Bischoff Seawater Process, 601... 

Bischoff and Rosenbauer (1989), Von Damm (1990), and Edmonds and Edmond (1995) have suggested a 3-component mixing model between (1) a deep-seated highly-concentrated brine, (2) a low-chloride vapor-phase generated during phase-separation, and (3) normal seawater. These processes have important implications for isotopic exchange reactions with minerals and for effects of phase-separation on AD and of vent fluids. 

The Bischoff wet FGD process utilizes either limestone or lime as the sorbent. Bischoff s early scrubber experience was with lime and natural oxidation. With the increased demand for gypsum as the preferred byproduct and the use of sea water for at least a portion of the process water, Bischoff has evolved their wet FGD technology in the direction of limestone with forced oxidation. Limestone is the preferred sorbent when seawater is used as the process water.
