The technology for coke oven gas purification

The coke oven gas deter technology USES the special deter adsorbent of our company, which has the double characteristics of high removal rate and high removal accuracy. According to the tar content in coke oven gas and tar content in coke oven gas after purification, the first or multistage removal process can be adopted.

 The technology for coke oven gas purification

The coke oven gas deter technology USES the special deter adsorbent of our company, which has the double characteristics of high removal rate and high removal accuracy. According to the tar content in coke oven gas and tar content in coke oven gas after purification, the first or multistage removal process can be adopted.

Tar content in raw gas: 10~1000mg/Nm3

Purification precision: Coal tar content in the refined purified gas ≤1mg/Nm3

 Feed gas pressure: 2~2000KPa(g), The system pressure drops to 1~5KPa


The technology of coke oven gas naphthalene removing purification



The coke oven gas naphthalene removal technology developed by our company and also we  uses our company's special naphthalene removal adsorbent, using a fixed bed dry naphthalene removal; adsorbent can be reused for many times, high removal accuracy and other characteristics. According to the content of naphthalene in coke oven gas and the requirement of naphthalene content in purified coke oven gas, one or more stages of naphthalene removal processes such as coarse naphthalene removal and fine naphthalene removal can be adopted.

Naphthalene content in coke oven gas: 10~3000mg/Nm3

       Purification precision: Naphthalene content in the refined purified gas ≤1mg/Nm3

Regeneration gas: Coke oven gas purifies the gas, nitrogen, PSA desorption gas, steam

Regeneration temperature: 150℃~170℃

 Feed gas pressure: 2~2000KPa(g), The system pressure drops to 1~5KPa




Technology of removing hydrogen sulfide from coke oven gas:

The coke-oven gas hydrogen sulfide technology developed by our company USES our high-efficiency desulfurizer and adopts fixed bed dry method to remove hydrogen sulfide, which can be used in combination with tar and naphthalene removal process, with high removal accuracy. According to the requirement of hydrogen sulfide in coke oven gas and hydrogen sulfide in coke oven gas after purification, the first or multistage removal process can be adopted

H2s content in raw gas: 1~3000mg/Nm3

      Purification precision: H2S content in the refined purified gas ≤1mg/Nm3

Feed gas pressure: 2~2000KPa(g), The system pressure drops to 1~5KPa




Control mode and characteristics

Control mode: operator can be used to control the cleaning device manually on site; the controller and instrument cleaning device can also be used for control. The controller can select DCS, FCS and PLC control system according to the device size and control requirements.

characteristics :The remote control of valve switch can be realized in the control room without operators to switch valves on site, and the control of arbitrary combination and switching of multiple towers can be realized, which not only improves the convenience and flexibility of the device operation, but also ensures the long-term, stable and safe operation of the device.
