6 slides from Solvang ASA's technical presentation, July 2024
Slide 1: Seawater Flue Gas Desulphurisation – (SWFGD)
Seawater Flue Gas Desulphurisation – (SWFGD) Reduce Cost of Electricity • Pioneer in SWFGD with 1st installation in 1968 • Lower power consumption resulting from packed tower design • 50+ GW in Power alone • No additional cost for reagent and • Proven experience with end-product disposal 1,000 MW un
Slide 2: SWFGD Chemical Process
SWFGD Chemical Process From Seawater H+ + HCO3- CO2 + H2O (neutralisation) CO2 SO2 + H2O SO32- + 2H+ H2O (absorption) SO42- (oxidation) SO42- (Sulfate), already SO32- + ½O2 SO42- present in Seawater (typical 2.7kg/m3) From Air CO2 emissions negligible vs stack emissions • Recycles sulfur back
Slide 3: SWFGD Process Flow
SWFGD Process Flow • Flue Gas Path: – De-dusted flue gas pass through booster fan (if required) before entering into GGH – Flue gas cooled down by GGH is scrubbed with counter-current seawater in absorber – Clean flue gas is reheated by GGH before exhausted through the stack • Seawater Path: – Part
