Solvent Recovery System

About This Project

By helping one client solve a solvent problem, we also helped them make a positive impact on the environment.


A major client was bringing in an average of 22 barrels of new solvent per month, at a cost of (at that time) $800 per barrel, while also paying to dispose of used solvent.

The challenge was to reduce incoming shipments by finding a way to recycle the solvent they already had.


The Kroeschell solution was to install a new, state-of-the-art solvent still. The still heats the used solvent in a vacuum (utilizing steam that comes from the company’s generators) which results in a return of three-quarters of clean solvent to one-quarter sludge.

This recycling effort produced the following positive effects:

  • The company only purchases new barrels of solvent when necessary to keep up with production demands.
  • The company has saved on average $300,000 per year.
  • The solvent still paid for itself in nine months.
  • The amount of material to be disposed of dropped dramatically (as did costs).
  • A smart business decision also became a smart environmental decision.


Since the installation of the still the company:

  • Has realized over $1,500,000 in cost savings.
  • Have cut their use of new solvent.
  • Have slashed their need to dispose of used solvent.
