SWCHEM provides methanol synthesis technology from coke oven gas, COG, supported by proprietary SMR technology, secondary steam reforming catalysts and engineering experience in methanol production.
The process uses a cylindrical reformer equipped with refractory insulation, a cooling water jacket and a central tubular metal burner. The reformer is filled with secondary steam reforming catalysts to support stable conversion of coke oven gas into methanol synthesis gas.
SWCHEM adopts a cylindrical reformer consisting of the furnace shell, main steel structure, refractory insulation materials and cooling water jacket.
The reformer is loaded with secondary steam reforming catalysts and equipped with a central tubular metal burner, enabling stable and efficient conversion of coke oven gas.
Before entering the conversion furnace, coke oven gas and oxygen are mixed with steam in a controlled proportion.
The steam-to-carbon ratio is typically maintained at 2.5–3.5, according to process requirements.
The temperature of the steam–coke oven gas mixture entering the reformer is typically around 600–650 °C. The temperature of the steam–oxygen mixture is typically around 250–550 °C. The gas mixture temperature should be maintained above the ignition temperature of coke oven gas to ensure stable operation. The operating pressure of the reformer is generally 2.0–3.5 MPa(g).
Due to mild operating conditions and easy process control, the reformer and burner have a relatively long service life, generally two years or more, meeting the requirements for long-term continuous operation.
The production capacity of a single train can range from 100,000 to 2,200,000 tons per year, depending on project requirements.
