EVAPORATION & CRYSTALLIZATION FACILITIES (SHI)

Sumitomo's plate-type falling film evaporator has been delivered to a wide variety of industries, including automobile, semiconductor, food, chemical and pulp and paper industries. In all cases, these evaporators have generated very high customer satisfaction. Because SPE allows the customer to choose evaporators that utilize a wide variety of methods (low-pressure steam multiple-effect system, vapor recompression system, injector vapor recompression system, etc.), SPE is able to deliver the exact system of equipment needed. This, combined with other superior characteristics of the Sumitomo evaporator (scaling countermeasures, high concentration, and energy savings) that have been developed through continuous research and development, has resulted in the enduring loyalty of SPE's customers.

Structure of SUMITOMO Evaporator

Mist separator : Depending on the liquid, wire mesh pad, Sumitomo SFLOW® or sieve tray can be chosen.
Distributor : Developed through long years of experience, the structure minimizes uneven distribution and is resistant to scaling.
Bottom strainer : This piece is installed when using liquids with intense scaling. Its structure catches scales falling out from the heating element and makes them even finer.

Vapor Recompression System (VRC System)

Adopting the VRC method actualizes high concentration and volume reduction of products through high efficiency, low carbon emission and energy conservation.

  • Generally, the operating temperature is set at 100ºC (vapor temperature of the atmospheric pressure). Heating steam and cooling water are not necessary upon steady operation. Moreover, process liquid may thermally metamorphose is put under reduced pressure and the operating temperature conditions are eased for treatment.
  • This method releases almost no externally-directed latent heat, allowing extremely high heat efficiency.
  • Furthermore, both multiple effect for energy conservation and versatile one-evaporator/2-3 liquid treatment are possible. Various switching systems are also available for liquids with intense scaling. Indeed, we are able to offer many different kinds of designs to meet our customers' demands.
