EPC general contracting project of Panmei joint coking cooperative operation project of coking coke oven flue gas desulfurization and denitrification project

1. Project Overview

Project Name: EPC general contracting of coke oven flue gas desulfurization and denitrification project of Panmei Joint Coking Cooperative Operation Project

Construction unit: Panzhihua Panmei United Coking Co., Ltd

Project address: Panzhihua Panmei United Coking Co., Ltd.

Furnace type: coking road

Exhaust gas temperature: 260°C

Flue gas volume: coke oven flue gas volume 320000 Nm³/h; The flue gas volume of CDQ is 40000Nm³/h.

2. Routing

This project adopts the process of "heating furnace re-ignition + SCR denitrification + waste heat boiler + CFB desulfurization + bag filter + induced draft fan"; The two furnaces share a set of equipment, and the purified flue gas is discharged back to the original chimney.

3. Emission indicators

Dust removal system: the original particulate matter concentration ≤ 500 mg/Nm³ (Dry base, 8%O₂), Particulate emission concentration < 10 mg/Nm³ (Dry base, 8%O₂)

Desulfurization system: 1800 mg/Nm³ (Dry base, 8% O₂), SO₂ emission concentration < 30 mg/Nm³ (Dry base, 8%O₂)

Denitrification system: NOx original concentration 1350 mg/Nm³ (Dry base, 8%O₂), NOx emission concentration ≤50mg/Nm³ (Dry base, 8%O₂)

Ammonia escape rate: ≤ emission concentration3 ppm (Dry base, 8%O₂)
