FGD scrubbing, paid for in pressure drop
Power-plant stack gas cleaned in a high-energy venturi wet scrubber, with removal and fan power falling out of the same solve.
The actual dark-mode canvas: hot stack gas accelerated through a venturi throat where scrubbing liquid is injected, leaving clean gas to the stack and a sulfur-bearing slurry below.
Removal is paid for in pressure drop
A venturi scrubber's collection efficiency comes from the relative velocity between gas and injected droplets, and that velocity is exactly what costs pressure drop — so emissions performance and fan power are the same number seen twice. Both are solved here, which is what makes the trade visible instead of assumed.

Calvert momentum-exchange pressure drop plus cut-diameter grade efficiency, with soluble-gas absorption.
Stream throat pressure drop, liquid-to-gas ratio and stack SO₂ from the plant's OPC-UA server into this flowsheet's twin comparison — scrubber performance is bought with pressure drop, and a drift there is both an emissions and an energy signal.
