45697558, Feb 11, 1986

Filed:

Feb 14, 1985

Appl. No.:

6/701714

Inventors:

Thomas J. McGinley - Wilmington DE
Peter Hosler - Wallingford PA

Assignee:

Sun Refining and Marketing Company - Philadelphia PA

International Classification:

C10G 2120

US Classification:

208326

Abstract:

This invention relates to a low energy process for the solvent extraction of aromatic hydrocarbons from hydrocarbon streams containing the same, using as the solvent N-cyclohexyl-2-pyrrolidone together with small amounts of water. This solvent may be recovered from the aromatics by cooling the aromatic/solvent mixture, and adding water, whereby separation takes place without distillation. The solvent may then be separated from the water by heating the solvent/water mixture.

Suntech, Inc. - Philadelphia PA

International Classification:

B01D 924

US Classification:

62532

Abstract:

In crystallization units such as wax crystallization units where a scraped surface double pipe heat exchanger type chiller is used, the improvement of replacing the scraped surface chiller tube with a porous tube to provide positive flow of coolant through the tube wall to prevent crystal deposition on the process side of the tube, whereby crystal degradation is eliminated and increased filter rate is obtained.
