Evaporation

Our decades of experience in designing and manufacturing the best and most cost effective evaporation system solutions for each of our clients’ applications provide the best technical and commercial fits.  We design and integrate evaporation systems for the pharmaceutical, chemical, biotech, food, dairy, nutraceutical, natural gas drilling, and environmental industries.  These pages are dedicated to provide information regarding our evaporation technologies.

We specialize in:

 

Evaporation Process Principles

(For a more complete description of the variety and applications for evaporation technologies please see our White Paper.)

Evaporation is a unit operation that is used to remove a liquid from a solution, suspension, or emulsion by boiling off some of the liquid, often under vacuum but sometimes at atmospheric or even positive pressure.  Evaporation requires heat energy and is thus a thermal separation.  The evaporation process begins with a liquid and ends with a more concentrated liquid or even a dry solid.  During the evaporation process a portion of the feed liquid is boiled from the feed.  The product can either be the liquid which is concentrated or the liquid which is removed by the evaporation process.

The product often requires that it is subjected to minimal thermal stresses to keep it from degrading during the evaporation process.  This is accomplished either by minimizing the exposure temperature and/or the time of exposure to elevated temperatures. Over a number of years and in various industries each with their own applicational requirements, a variety of different evaporation technologies have been developed.  Each of them has unique advantages as well as disadvantages.  Our first goal is to determine with our client which of the many processes to apply to match their process needs.

We support our evaporation technologies by test and development facilities in the US, Europe, and Asia, where we continually refine, improve, and apply our expertise to determine the best available evaporation technology for each client.

Our systems operate on steam with high thermal economy, on hot oil, molten salt, or with mechanical vapor compressors. 

Our evaporation systems will improve the overall performance of your operation with their low operating and capital costs with our accurate deliveries.

For the Chemical, Environmental, Food, Dairy, Beverage and Pharmaceutical industries, we design and manufacture to ASME and CE codes, 3A sanitary standards, as well as other international standards for China and Australia.
