Smart spin pack filter design


For an application where a polymer with filler had to be filtered, the customer using mesh and sand packs to protect the spinnerets, was facing rapid blocking of his spin packs, making the process inefficient. We solved the problem, by designed a compact spin pack that has 7x the surface area of the equivalent mesh pack. The result was that the process is stable now, much longer service life of the filter pack and a steady + predictable increase of the pressure drop.
