Hydrowax

from Wikipedia, the free encyclopedia

Hydrowax is a paraffinic ( alkane-rich ) fraction from the hydrocracker with a low nitrogen, sulfur and nickel content. The boiling range is between 340 and ~ 560 ° C.

There are several ways to quantify the paraffin content of the Hydrowax. One is the BMCI (Bureau of Mines Correlation Index). The BMCI has a value of 0 for hexane and a value of 100 for benzene . The lower the BMCI, the more suitable the Hydrowax is as a feed product for steam crackers .

For the steam cracker it represents a so-called advantageous feedstock . The yield is similar to that of a naphtha cracker. However, when steam cracking Hydrowax there is more ethylene cracker residue (ECR), less pyrolysis gasoline and less hydrogen compared to naphtha cracking .

HydroWax is a registered brand name and a trademark used by Sasol Wax for water-based wax dispersions and oil emulsions made from synthetic and natural waxes and oils or their mixtures for use in industrial areas such as: B. paints & varnishes, paper & packaging, chemicals & blenders, construction industry and insulation materials as well as wood-based materials.
