The present invention relates to the process for molecular separation of hydrocarbons using nanopore membrane comprising passing the hydrocarbon feedstock with or without separation enhancing additive/additives to produce permeate streams having different refractive indices which resonate with that of naphtha, kerosene and heavier molecules.

Process for molecular separation of hydrocarbons using nanopore membranes

The present invention relates to a co-solubilization process for preparation of a polymer modified bitumen/asphalt and emulsified polymer modified bitumen/asphalt from bitumen, polymer, emulsifier etc. The present invention further relates to a polymer modified bitumen comprising bitumen and styrene-butadiene-styrene (SBS) linear co-polymer having high softening point. The present invention also relates to the use of the polymer modified bitumen and its emulsion in in micro-surfacing for maintenance of pavements.

Co-solubilization process for preparing modified bitumen and product obtained thereof

The invention concerns with improved and more flexible deasphalting process for production of lube oil base stock as well as feed stock for secondary processes depending on requirement from heavy residual hydrocarbon oil containing saturates, aromatics, resins and asphaltenes etc by contacting the oil with a solvent comprising of hydrocarbon containing two to six carbon atoms, preferably LPG having C3-C4 hydrocarbons and mixture thereof at predetermined deasphalting conditions wherein the yield of deasphalted oil including its quality is controlled by varying the deasphalting conditions including the operating temperature. The yield variations of 15 to 60 wt % is achieved by swinging the temperature by about 10-20&#xb0; C. within the operative temperature range of 70-130&#xb0; C. keeping the rest of the operating conditions including solvent to feed ratio same. The LPG solvent can be recovered using supercritical mode of operation using technology known in the art and recycled.

Deasphalting process for production of feedstocks for dual applications

An improved furfural extraction process for lube oil base-stock production from hydrocarbon oils containing aromatic type material by the addition of a solvent comprising of furfural and a co-solvent, said process being conducted in a continuous countercurrent extraction column that facilitates phase separation and increases the raffinate yield while maintaining the same raffinate quality measured by raffinate refractive index.
