Carbon monoxide is commonly used as the raw material for the shift reaction in hydrogen production, chemical synthesis and reducing agent. The main sources are semi-water gas, water gas, regeneration gas from copper washing of synthetic ammonia, blast furnace gas, converter gas, calcium carbide furnace gas, carbon black furnace gas and yellow phosphorus tail gas. When carbon monoxide is used as a raw material for chemical synthesis, such as the production of ethylene glycol, it is necessary to purify carbon monoxide to the concentration required by the synthesis process. In view of this technical and market demand, DKT, after years of R&D and industrial application practice, has developed two types of special adsorbent and patented technology for purifying carbon monoxide, which can purify and obtain high-purity carbon monoxide product from carbon monoxide-containing mixed gas with high efficiency, high recovery, low energy consumption and low cost.

Technical features and advantages:

- Advanced and proven technology, and simple process flow;

- The special adsorbents for carbon monoxide developed and produced independently has high separation coefficient and good purification effect;

- The special adsorbent for carbon monoxide is pre-reduced before leaving the factory, and can be used directly after on-site loading. No need for long-term on-site reduction, while the problems of large gas consumption for on-site reduction and chlorine-containing gas emission pollution during the reduction process can be avoided;

- Adopting the patented pressure swing adsorption technology independently developed. The plant is flexible, safe and stable in operation, and occupies a small area;

- High recovery of carbon monoxide, low energy consumption and low operating cost for purifying carbon monoxide.

Application:

- Purification of carbon monoxide in semi-water gas, water gas, regeneration gas from copper washing of synthetic ammonia, blast furnace gas, converter gas, calcium carbide furnace gas, carbon black furnace gas and yellow phosphorus tail gas;

- Purification of carbon monoxide in other mixed gases containing carbon monoxide.
