Lectrodryer |
|
Currently, Lectrodryer serves such markets as hydrocarbon refining, chemical processing, gas manufacturing and refining, solvent drying, sewage/water treatment, and power generation. In fact, 90% of the 100 largest industrial firms in the United States use Lectrodryer equipment for dehumidification. As the largest manufacturer of liquid dryers in this hemisphere, Lectrodryer is a principle supplier to chemical processing plants and oil refineries |

Actually, the name is somewhat misleading since we design and manufacture a "reactivator." A dryer is easily built. It is as simple as purchasing a container of desiccant from any desiccant manufacturer and putting an inlet and outlet connection on it. The fluid to be dried can then be passed through the container and water will be removed. The trick, however, is to use it a second time and this requires returning the desiccant to its original state of condition or as nearly to it as possible. This is reactivation. |

The most common type of adsorption system employs a dual-tower, fixed bed, cyclic operation. While one tower is adsorbing for a period of time, the other tower is reactivating. Since adsorbing is typically a continuous operation, the beds are continuously switched back and forth between the adsorption and reactivation modes of operation. The entire gas or liquid stream flows through the particular bed in the adsorption position. Simultaneously, the bed in the reactivation position is being reactivated by flowing gases from various sources. In many applications, the adsorbate in the fluid is water and the unit itself is referred to as a "dryer." As the wet process stream enters the fresh desiccant bed, the water vapor is adsorbed in a finite length of bed called a mass transfer zone (MTZ). This MTZ is defined to be the bed length through which the concentration of the adsorbate is reduced from essentially inlet to outlet conditions. As the wet gas continues to flow, the bed may be divided into three distinct zones: the dynamic equilibrium zone, the MTZ, and the remaining active zone. The dynamic equilibrium zone is where the adsorbate is in equilibrium with the adsorbent and no mass transfer occurs. The final zone in the bed is the yet unused part or the "active zone." The bed is exhausted when the leading edge of the MTZ reaches the outlet end of the bed. |
