Air Pollution Control Facility Sample Clauses

Air Pollution Control Facility. The air pollution control facility installed as part of Units 3 & 4 include a series of wet lime slurry based scrubbers and related equipment to remove sulfur dioxide and fly ash from the flue gases prior to discharge through stacks to the atmosphere as required by applicable environmental regulations. The lime slurry comes in contact with flue gas in order to absorb the sulfur dioxide and fly ash through a chemical reaction. After contact, the lime slurry drains into the recycle tank where it can be reintroduced back into the sulfur dioxide and fly ash removal process. A bleed stream controls the buildup of suspended solids in the recycle tank by continuously removing the solids and transferring it to lined disposal ponds. In the disposal ponds, the solids settle out and form a sludge. The supernatant water in the ponds is returned to the scrubbers for reuse. The major components that are included in this facility are: scrubber lime system, scrubber vessels, mist eliminators, reheaters, draft fans, ductwork, stack, disposal ponds, piping and drains and associated electrical and mechanical equipment.
