Solvent Recovery Systems

Wintek’s solvent recovery systems reclaim precious solvents during industrial processing. Additionally, our systems are custom-designed by Wintek engineers to recover solvents by optimizing the configuration of condensers, receivers, vacuum pumps, and controls in a packaged system. On the contrary, all components arrive on site pre-piped, pre-wired, and factory tested to assure proper operation. Besides that, systems also meet ANSI B31.3 with materials in carbon steel, stainless steel, or Hastelloy.

These systems are used in many industries including the following: chemical, pharmaceutical, metal powders, flavor and fragrance, and PET solid state.  In many cases we are also sealing a liquid ring pump with one of these high vapor pressure solvents to maximize recovery and reduce potential contamination or environmental concerns. However, this requires an extensive knowledge of how equipment, such as a booster, affects sealing a pump with a potentially high vapor pressure solvent, even when operating at deep vacuum.

Wintek’s equips our solvent recovery systems with:

  • A heat exchanger to condense the incoming process stream
  • A vacuum receiver to accumulate the condensed solvent
  • Liquid ring vacuum pumps sealed with the condensable solvent to maximize recovery
  • All the necessary controls to facilitate system operation

Wintek builds its solvent recovery systems to the relevant codes (ASME, ANSI B31.3 and area classification).

Additionally, the customer dictates the materials of construction (typically carbon steel, stainless steel, or Hastelloy).
