After chemical product recovery, coke oven gas still contains impurities such as sulfur, tar, naphthalene, and benzene. In processes including coke oven gas power generation, CCPP power generation, coke oven gas compression, coke oven heating, coke oven gas cutting, and coke oven gas-based chemical production, these impurities can easily cause production problems such as nozzle blockage, corrosion, excessive SO₂ emissions after combustion, carbon deposition, and catalyst poisoning. Therefore, harmful impurities in coke oven gas need to be deeply removed.
Since wet desulfurization and oil washing naphthalene processes have high investment, complex operation, harsh production environments, and low removal precision, the fixed-bed dry TSA process is a more economical choice.
Our company adopts the "segmented dry TSA purification" process to remove impurities such as H₂S, tar, naphthalene, NH₃, benzene, HCN, and organic sulfides from coke oven gas in a single pass, obtaining qualified purified gas.
Technical Features
• Segmented removal of harmful impurities, long adsorbent service life.
• High impurity purification precision.
• Wide operating pressure range of 5KPa~3MPa, low energy consumption, and operating flexibility of 10~120%.
• Low pressure drop during the purification process, generally 2~50KPa.
• Gas regeneration process thoroughly solves on-site operational environmental pollution and wastewater discharge and treatment issues.
• High degree of automation, with functions such as adaptive adjustment and automatic fault diagnosis, convenient startup and shutdown, and capable of unmanned automatic control.
Plant Scale
1000~500000Nm³/h.
