Anshan Shengmeng Coal Gasification Co., Ltd. Coke Oven Flue Gas Desulfurization and Denitrification Phase II Project (EPC) Project

     Anshan Shengmeng Coal Gasification Co., Ltd. originally had two 2×5.5m side-loaded tamping coke ovens. The original process route was SCR (selective catalytic reduction method) + GGH heat exchanger + wet desulfurization (limestone-gypsum wet method) ) Process. Due to the stricter national environmental protection policy, the original process cannot meet the requirements of the "Opinions on Promoting the Implementation of Ultra-Low Emissions in the Iron and Steel Industry" (Huantaiqi [2019] No. 35), so the original process desulfurization and denitrification system needs to be modified, and the dry quenching The flue gas from the coke pre-storage section is merged into the coke oven flue gas (the coke dry quenching flue gas interface is reserved).

  
  The process route of this technical transformation is the recovery of the original flue gas waste heat boiler + SDS sodium bicarbonate dry desulfurization + bag dust removal + SCR (selective catalytic reduction) denitrification process (reuse of old) + net flue gas waste heat recovery (reserved) .
