different ways to do it.  steam distillation, expression, solvent extraction and efleurage. the first is the easiest and what you want to know if you are looking for a how to. Use hot steam, like a steamer, you'll end up with the oil and water.  then separate the oil.  \n\nthe other methods are more complicated, but you do end up with more oil.  but at what price?  second method the is to use pressure or centrifugation. At home, not likely you have anything to make this work.   The third method you use a solvent, but then the oil and solvent are mixed.  You then evaporate the solvent (you can get at a whole foods store to do this) when the solvent is evaporated you are left with a heavy, waxy substance called concrete. Then you have to separate the liquid from the was.  it's great because it is most concentrated from of aroma, but very time consuming and complicated.  That last, efleurage is a really long process using animal fats and alcohol. Although essential oils main usage is in cosmetics and perfumery, many of them do have proved therapeutic properties.

Heat will also help break up oil.  Look at a grease-ridden frying pan after washing it with cold water and soap.  Then look at it after you have to wash it again in hot water.

sorry i dont really know, but a kit designed for extraction might work o.k. I'm guessing that you have tried regular high salt or phenol based methods and these have not been successful, perhaps repeating the extraction protocol on the resulting product may help.\n\nhad to laugh at the above answer, clearly has no idea but has got the hang of copy and paste!

Isn't that the rancid smelling oil from the male Gingko tree ?  If you're trying to clean it up, use hot soapy water. If you trying to inject it into a gas chromatograph, use a low weight alcohol.

Part of pharmaceutical manufacture involves solvents such as isopropyl alcohol which are driven off during the process. Typically, the volatile solvents are incinerated because letting them just go to the atmosphere is considered pollution.  An attractive option to VOC incineration is solvent recovery. This is a process whereby the process hydrocarbon is sent not to an incinerator but to a bed of activated carbon or zeolite. This material has the unique property by which hydrocarbons are highly attracted and adsorb to it. This functionally filters the hydrocarbon from the process stream effectively removing the pollutant.  The hydrocarbon on the carbon may then be de-sorbed and processed such that the hydrocarbon is recovered. The recovered hydrocarbon may then be re-processed, saving the manufacturer the cost for more solvent. This amounts to a huge cost savings in manufacturing the product, as upwards of 95% or more of the solvent is driven off the product and upwards of 98% of the solvent is filtered from the stream. That means that more than 93% of the solvent may be recovered and reused. Solvent recovery systems, when properly applied will actually pay for themselfs in recovered solvent within 2 years.

This leads not only to costly equipment repair, but to expensive down time as well. Combine that with new, stricter environmental regulations concerning the disposal of waste oil, and you have a potential operating capital drain. With the application being Hydraulic oil, the primary degrader of oil, HEAT, is not a factor. Water and dirt particles are the enemies of the hydraulic oil.\n\nOur engineered process removes these contaminants¹ quickly and efficiently. Our portable systems will connect to the injection molding machine oil reservoir through two 1² lines. The units can be equipped with quick connect/disconnect fittings. The flow rates range from 3 ­ 24 GPM and filter through three filtration stages. Using a cycle of passes through the system, 98 percent of all contaminants are removed from the hydraulic oil. This simple service can extend your hydraulic oil life 8 ­ 10 times or more.\n\nThe Glanon Hydraulic Oil Filtration System is shipped from the factory equipped and ready for immediate service. Portable and easily maneuverable, this system can service multiple Injection Molding Machines in a single day.\n\nAn Injection Molding Machine can easily be serviced without manually draining and refilling the oil. Hydraulic system maintenance hours will be reduced, oil life will be increased, and environmental impact will be minimized.

Small area:  Use paint remover (paint stripper for furniture).\nPaint remover (the original kind) uses methylene chloride to soften the paint so it can be removed easily.  Problem:  methylene chloride evaporates very quickly.  Possible solution:  after applying the stripper, put a plastic polyethlyene sheet over the paint to keep the methylene chloride from evaporating so quick (work on cool days/evenings too).  Methylene chloride works on epoxy based paints which are normally chemically resistant.  Methylene chloride is becoming harder to get because of VOC requirements and CFC considerations.\n\nLarge area:  use sodium hydroxide (lye) or Drano crystals or similar caustic.  **Concentrated** (saturated solution) lye will soften the paint so it can be brushed away.  Its less expensive than paint stripper.\n\nPLEASE READ CAREFULLY:  \n\nYou are going to have a disposal problem - don't wash it down the drain or you may be fined.  The EPA monitors the drains for polluters.  \n\nThese are very hazardous chemicals that require respirators, adequate air, protective chemical equipment (rubber gloves, face shields), the area needs to be isolated so a pet or kids don't come in contact with the chemicals.  If you won't take these precautions or don't know what you're doing, call a professional.  Truly.\n\nFor the methylene chloride residue: pickup the old paint residue and let it dry out.  Then you can dispose of the residue in plastic bags in the garbage (dry paint is considered non-hazardous in most areas, but not all - contact your waste management service).\n\nThe lye will soften the paint and can be dried out, but even the dried crystals can be hazardous if water is re-introduced - you may be able to neutralize the waste with a weak acid like vinegar to neutral pH, and then dry it out and dispose of it.  You'll need some pH strips to test for neutral pH.  Dried, neutral pH paint can be disposed the same way as regular dried paint - the exact method depends on where you live and your waste disposal service.  Most areas have free disposal days for hazardous waste if you are otherwise required to pay.\n\nBE CAREFUL with powerful chemicals and USE PRECAUTIONS so you don't hurt yourself, or others.\n\nAnother method: Sandblast.  Look up a sandblast service in the Yellow pages and they'll come out with their portable blasting unit.  Paint removal is their job.  I can't advise further because I don't know the constraints, paint type, substrate, enclosed area, etc.  \n\nMost paints are acid-resistant to some degree, so muratic isn't effective; most paints ARE vulnerable to alkaline solutions (but not all).  Concrete is an alkaline material, so won't be attacked to the same degree as with nuratic acid.  Muratic acid will attack and eat up the concrete (maybe that's what you want, but probably not).

I would consult with the unit manufacturer, especially if the unit is under warranty.  Their technical rep. may know how others deal with this problem and with what success.  They would want to know how clean and moisture free the oil is.  Also consider whether there is enough oil to warrant special purification equipment.  Often used oil is returned to a company that specializes in recycling spent oil to keep it out of the environment and find a good use for it.  They have the equipment to do the job.  Good luck.

Try it.\nThe easiest source of citric acid is lemon juice.\n\nThe usual solvent for nail varnish is acetone. This is the chemical with that lovely smell in nail polish remover. The point of using varnish is that watery things do not dissolve it.

Fingerprints are detected by the oils left behind-washing them in soapy water would remove them-alcohol will also do the trick.
