Case Studies



Small Spaces - Big Designs

An international sweetener company contracted ProSep to help with a US plant expansion. ProSep was challenged to design and supply purification systems that would normally require more space than available.

Working with the plant’s process engineering & design teams ProSep was successful in designing equipment that fit into the allocated spaces and that provided process capability.  This was accomplished by using multi-levels for systems, adjusting piping manifold to fit space, positioning valves and instruments in the manifolds, and by fabricating vessels with special pad flanges, nozzles, and manways


Made in USA - Installed in Asia

A corporate customer with years of experience using ProSep systems throughout the world challenged ProSep to design and build a six-bed ion exchange system that could be shipped and installed in an Asian plant for a competitive price.

Using ASME standards ProSep designed and built system “break-away” vessel units. Piping and fittings were built to ASME standards with customer plant connections built to DIN standards.

Each vessel unit, with piping manifold in place, was shipped in a conventional shipping container. Interconnecting piping was color coded and shipped in sub-assemblies for easy connection during installation. The system was completely assembled, inspected and tested in the US before break down and shipment to Asia.


Designed in USA - Built in China

An international customer asked ProSep to provide design, engineering, and technical support for a large separation system that would be built in China. The customer had previously engaged ProSep to design equipment and to build separation systems in other countries.
ProSep designed and supplied production drawings for equipment of the separation system.  ProSep also assisted the customer with the evaluation and selection of component vendors and vessel fabricators, as well as training and QC of the selected vessel fabricator.


Nanofiltration Recovery of Regenerants

The production of highly colored salty effluent, from ion exchange resin decolorizers, has found an answer by using nanofiltration (NF).  Brine recycling plants permit a decrease in waste rejection up to 75-90%, and the NF permeate, containing NaCl and small color bodies, can be reused for regeneration of the decolorizing resin
ProSep has placed a number of systems in cane sugar refineries worldwide, and the first installed system has been in operation for nine years
