De-oiling process using enzymes

摘要: Compositions and methods are provided for cleaning de-oiling metal parts then degrading the removed oils or other organic compounds in an environmentally-friendly manner. The compositions generally contain surfactants to remove enzymes degrade oils. Generally, both aliphatic aromatic normally present standard oils, lubricants, cutting greases from (i.e., "solubilized") by (although may also assist this process) ultimately broken down into relatively short-chain fatty acids enzymes, processes being carried out aqueous medium. include (a) one more alkylphenol ethoxylates; (b) alkaline salts of alkane sulfonic acid; (c) alkanolamines solution. Suitable monomethanoxigenase, alcoholdehydrogenase, aldehydehydrogenase. Preferably, enzyme solution contains all three types just-listed order a wider variety derived form petroleum products.
