A system of stationary solid beds performs simulated “moving” and solid-fluid contacting by rotating a single rotor. The rotor can make stepwise rotational turns, simulating beds moving in opposite directions. Since all motion is relative to a reference frame, the solid beds are stationary in reference to the earth but “moving” in reference to the rotor. Heat or mass transfer materials are stored in solid beds. This device can be used for heat transfer, chemical reaction, adsorption and ion exchange operations, which require regeneration of solid beds after the operation.

All three CYPRESS SYSTEMS' moving bed contactors can have co-current or countercurrent solid versus fluid contacting patterns. In most applications, countercurrent contacting is more efficient than other flow patterns and can be easily implemented with our moving bed technologies.

• Incremental Countercurrent Regenerative Heat Exchangers 

Type 2 true moving  bed and simulated moving bed methods can be used for regenerative heat exchanger designs. These novel designs can reduce bed mass and leakage rate by an order of magnitude in comparison with traditional rotary wheel designs.  

• Oxidative adsorption process for gas pollutants removal with activated carbon

Activated carbon has been known for decades to remove gas phase pollutants such as SO2 and NOx. Regeneration of used activated carbon was a limiting factor that prevented widespread use of this method in the past. With a type 1 true moving bed reactor, and a proprietary carbon regeneration method, CYPRESS SYSTEMS’ process is an order of magnitude faster and cheaper than existing technologies.

• Coal-Fired Power Plant - Air preheaters with type 2 true moving bed contactor and simulated moving bed contactor. Flue gas desulfurization with type 1 true moving bed reactor. Air preheater made with our moving bed technologies could be ten times less in weight and four times less in cost in comparison with traditional Ljungstrӧm air preheater.
• Sulfuric Acid Manufacturing – Stack gas SO2 removal with type 1 true moving bed reactor using oxidative adsorption on activated carbon. This process can reduce SO2 emissions to below 20 ppm. CYPRESS SYSTEMS’ process is an order of magnitude faster and cheaper than the Sulfacid® process.
