In some cases, previously described oil removal technologies based on the gravity separation of oil from the cleaning solution are unjustifiably cumbersome and expensive. Fortunately, smaller scale solutions are available for use in such applications. Oil Skimmers – Oil skimmers utilize a material which preferentially attracts oil (hydrophobic) to skim floating oil from a surface …
Preceding blogs have described oil removal techniques for industrial cleaning in some detail. It would be nice if this was always a simple consideration – but it is not! The case for using an oil coalescer is pretty clear cut as long as the cleaning chemistry is truly a “splitter” AND, THE OIL IS NOT WATER SOLUBLE. …
In the blogs Chemistry – Oil Splitting and Oil Emulsification – Part 1 and Chemistry – Oil Splitting and Oil Emulsification – Part 2, I discussed how oils are removed from parts using chemistry that either splits or emulsifies the oil. The next step is to collect and get rid of or recycle that removed oil. This …
“Splitting” of oil from a surface as described in a preceding blog is a part of nearly any oil removal process. Note – Even cleaning chemistry that is generally classified as an “emulsifier” has ingredients to promote the initial “splitting” of the oil from the surface being cleaned. These ingredients are often called “surface active …
