RPO rubber process oil furfural extract extender oil

 Leading supplier of Dubai RPO rubber process oil

We offer superior quality furfural extract that are processed after a long and complex distillation and refining process from industrial grade crude oil. The rubber processing oil offered by us contains high quantity paraffinice, naphtenic and Dubai aromatic rubber process oil in any of its prominent forms such as paraffinic, naphthenic and aromatic oil.

 In production technology we use advanced technology in processing our superior quality Base Oil, which includes solvent processing, removal of aromatics and other impurities along with hydro fining as well as hydro processing for chemical transformation and physical separation. Using such advanced processing technology, makes our rubber process oil with customize viscosity grades, which is ideal for refinery different types of rubberize application.

Rubber process oil from Abu Dhabi

UAE Rubbers process oils are commercially used to produce many products from rubber bands to a toy to the giant tyres for various vehicles as well .Rubber Process Oils mix to help in improving the dispersion of fillers and flow characteristics of the compound during further processing. There are tree type of rubber process oil and we are able to supply both grades aromatic and paraffinic rubber process oils.

Production of Dubai rubber process oil

In general, rubber process oil can be prepared from petroleum, in particular, lube oil fractions separated from petroleum. The lub oil fraction can be obtained as a distillate fraction, which contains a large amount of aromatic compounds having a high boiling point by vacuum distillation from residual oil which is separated from petroleum by atmospheric distillation or topping, or as asphalt oil which is obtained from vacuum residue.

Such lub oil fraction contains a large amount of polycyclic aromatics (PCAs). If it is possible to obtain a portion containing sufficient amount of aromatic compounds but less amount of PCAs from the lube oil fraction, it becomes possible to provide a preferable rubber process oil. As a method for separating some component(s) from an oil material, there is known solvent extraction. If a solvent having a selective affinity for aromatic hydrocarbon compounds is used in the solvent extraction, the aromatic hydrocarbon compounds contained in the oil material are possibly separated and taken off the oil material.

Aromatic extract

However, such a solvent having a selective affinity for aromatic hydrocarbon compounds has a stronger affinity for PCAs as well. Therefore, even if selective extraction is made on the lube oil fraction with such an extraction solvent in accordance with common measures, the obtained extract contains a large amount of PCA. The present inventors extensively examined a process for producing an oil having a less amount of polycyclic aromatics and a higher content of aromatic hydrocarbons.

Aromatic extract

As a result, the present inventors found that such oil can be produced efficiently by improving the solvent extraction. According to the present invention suggested are two embodiments of a novel production method in each of which improvement is made respectively on the solvent extraction with a solvent having a selective affinity for aromatic hydrocarbon compounds, so as to produce a suitable rubber process oil in which aromatic hydrocarbon compounds is sufficiently rich but the content of PCAs is less, with use of an oil fraction which is rich in aromatic compounds having a high boiling point as a starting material.

Rubber oil

In the first embodiment of production method for rubber process oil, a lube oil fraction collected from petroleum by distillation under reduced pressure, or a deasphalted oil fraction which is obtained by deasphalting the distillation residue from petroleum, is treated with a solvent having a selective affinity for aromatic hydrocarbons, then a mixture of the solvent and the extracted matter (first extract) is cooled under conditions which are regulated such that the content of polycyclic aromatics in a second raffinate to be separated is made less than 3% by mass.

Extract oil

Namely, the feature of the first embodiment resides in that the extract (1st extract) separated by solvent extraction of the raw material oil is cooled to a temperature lower than the extraction temperature to further separate into an extract (2nd extract) and a raffinate (2nd raffinate) which is to be recovered. In the second embodiment of the production method for rubber process oil, a lube oil fraction collected from petroleum by distillation under reduced pressure, or deasphalted oil fraction which is obtained by deasphalting the distillation residues from petroleum, is treated with a solvent having a selective affinity for aromatic hydrocarbons under extraction conditions which are regulated such that the content of polycyclic aromatics in the resulting extract is made less than 3% by mass and the aniline point of the extract is made 80 °C. or less.

Process oil

Namely, the feature of the second embodiment resides in that the raw material oil is extracted at a higher temperature and extraction conditions are controlled so that the extract is recovered in a specific and appropriate extraction yield. The process oil obtained by each of these embodiments of the production method is most suitable as rubber process oil which has a less content of polycyclic aromatics but is rich in aromatic hydrocarbons.
