Re-refining of used industrial oils

Hemant,

we have used thin film distillation to recrack heat transfer fluid where poor quality and contamination have reduced the flash point to <80°C, thin film was used distillation as we could utilise the high temp of the fluid without extra heating, we pulled 25" vacuum and removed the processed fluids with positive displacement pumps, we returned the fluid to a 210°C flashpoint with the lower flash point sulphur bearing lighter ends removed.
Where we had existing energy the thin film under vacuum was efficient, if you have zero access to spare process energy then normal distilation may be more efficient.

hope that gives a bit of info for you

Dear Hemanth,

The main problem with Acid/Clay treatment for waste oil is disposal of the acid sludge formed. This is a nightmare. No wonder government agencies all over the world discourage it.

For your information Castrol India did take up a study of the alternative methods and a pilot plant was set up at Patalganga, near Mumbai. A physical process of seperation, rather than the chemical proces (like Acid/Clay treatment)was adopted, but the poor yields resulted in a commercial failure. The unit was managed by Mr Satish Rao, currently in UK. If Castrol does not feel it is previliged information, Mr Satish Rao may be able to give some details. Pls contact him at raos@castrol.com . You may quote my name/reference when corresponding with Mr Satish Rao.

The main difficulty in India is that used oils are not segregated. Mixtures of use hydraulic oils, cutting oils, soluble oils, water and diesel etc are difficult to untangle by any process.

Regards.

There is a notification from the Ministry of Environmentwhich was published in the Gazzete if India in its May 2003 issue that acid -Clay process is banned in India for rerefing of used oil. Hence all the rerefining plants adopting the acid-clay process are to be changed to other environment friendly processes.This job is to be completed in a period of six months. So no acid-clay process is existing in our country since November 2003 officially.
A copy of the gazzete notification is with me and can be delivered to you on request.
Thanking You, Yours faithfully

Nice to See Dr Mishra on board, I had interaction with him during my IIPM Days and still would love to interact with him.
Thank you sir

Re refining of used industrial oil is a dead industry . Recently there was a talk that Castrol is putting up a refining plant (India) and collect oil from industrial users as a package for selling lubricants.

Is any regulation comming up in India or at large for conserving oil resources considering the base oil price hike and scarcity across the globe.

We are offering envoirnmentally friendly used oil re-refining technology.The process is as under:
1. Dehydration at atmospheric pressure
2. Total vaporization and fractional condensation at moderate vacuum and controlled temperatures to collect base oil, spindle oil and gas oil seperately during controlled temperature fractional condensation.
3. Hot contact bleaching with 2.5% clay ( this is currentlt permitted in India)

We are offering 7500 and 15000 TPA re-refining plant.Acid treatment section can be replaced by total vaporisation and fractional condensation section in conventional acid treatment plants at much lower investment.

This is the best option for industrial oils such as hydraulic oils,Turbine oils, compressor oils,gear oils and transformaer oils. The difficulties in segregation is the main task among the users. If they succeed in getting segrgation, this method is an ideal option. Needless to say that the reclaimed oil has to imparted with additive package to meet the required specification for the respective application. I am confidently saying this with the notion that 'oil nevers wears out; it only get contaminated and degarded during the usage'

I have filtered transmision oils, gasoline engine oils, diesel engine oils and hydraulic oils at a laboratory scale with coarse and fine clays and a mixture of both at 50%, with no pressure and at ambient temperature, so making a three stages process and came out up to a peach crystal clear colour of the filtered samples.

Now I want to try it out in a larger scale throught physical filtration by stages in a multiple vassel plant that I have constucted.

Please help. This seems to be the right place to find some knowledgeable people. I am the environmental officer at an Engineering company in South Africa. We use a soluble cutting oil for use in our lathes and milling machines. BY the time we need to dispose of this solution it could be anywhere betwen 5 - 25 % oil to water. How can I best seperate the oil from the water in order to send the oil to the recyclers.

I have an effluent treatment plant for an electroplating plant where i can put the water through, but if there is any oil still in solution, it tends to coat over and mess up my pH probes.

Thanks

Breaking the emulsion with 10-15lbs of rock salt is the easiest method. The rock salt acts like a floculant to seperate the two. After letting it settle for 3 - 5 days, all the oil will be on the top for removel. the rest will be brine. Hope this helps.

Hemant,

The best modern way of recovering lube from used oil, or waste oil, spent oil. involves most modern process, of handing lube oil.

The Existin system used are:
1. Vacuum Distillation plus clay treatment.
2. Vacuum distillation plus chemical treatment.
3. Hydrogen pre-treatment plus vacuum distillation.

The economics of re-refining of LUBE oil involves most modern energy efficent technique, with maximum yield.

In India, they are not allowing re-refining of used industrial oils by the conventional method of acid and clay. The suggested methods are thin film or complete distillation. What are the technical difficulties involved in the above processes, and what will be the cost of refining using these options?

Please help someone if you have any suggestions on how i can knock out the black colour in used oil by any means apart from thin film distillation as i do not have the capital to install such a unit. Chemical extraction? anything?

Dear Juicy,

Normally the clay treatment improves colour and smell. In this instance, multistage clay treatment would certainly improve colour and odour.

TAN of hydraulic oil new should be always less than 1.
Our DNR Corp HYD oil68 has TAN of 0.00022 means if it gets mixed with metal working fluid than also it will not contaminate MWF.Hence life of MWF will increase drastically. In case of injection machines this oil will outperform because to reach tan of more than 1 it will take around 10000 hrs.
