2 Clear-channel feed spacer. Variation of spacer strand thickness and orientation are methods of changing the fluid dynamics now being evaluated. To accurately determine effectiveness, the new designs must be tested - modeling is very complex and results difficult to predict. Thanks to the suppliers increasing the available options, this work has been started. Here the range of materials choices and designs has been expanded to keep up with the sepralator's potential.
Polyester is used for high temperature applications where hydrocarbons are present.
Again, stainless steel is used for the harshest environments. ABS and CPVC are also used for high temperature and for hydrocarbon and solvent compatibility. Fiberglass reinforcement of thermoplastics increases compressive and flexural strength of the tubes, and can also be used in other sepralator parts. Stainless tubes are often the ultimate choice, but due to cost and potential adhesion problems, are usually reserved for applications of extreme temperatures, aggressive chemicals and high axial pressure and pressure drop operation. Concentrate seals are molded in the full range of typical elastomers.
