I am looking for some reference sources pertaining to liquid liquid extraction in the refining industry. The liquid I am most interested for information about is the solvent NMP (n-methyl pyrrolidone) and how extraction conditions effects selectivity and solvency

Just to clarify...
i am looking for information about the refining process known as extraction within the refinery walls. Not the chemistry behind hydrocarbons. Are there any good references and or handbooks that are useful that any of you might know about.? Thanks

Thanks for the references sources from those who responded. I find all of them to be helpful in the question that I posed.

There are any number of references for using n-Methyl pyrrolidone and the modification of the liquid-liquid extractions of mixtures.

Take a look at those below and see if any help. Add detail to your question if necessary.

The thermal decomposition of N-methyl-2-pyrrolidone is minimized by the addition of minor amounts of water thereto prior to its being heated to temperatures in excess of 500.degree. F. This is of particular importance in processes using N-methyl-2-pyrrolidone as an extraction solvent to remove aromatics from mixtures of aromatic and non-aromatic hydrocarbons and wherein the N-methyl-2-pyrrolidone is recovered from the extracted fractions by thermal means such as flash evaporation and distillation.

My college course on that subject was called, "Mass Transfer and Separations." The textbook for the course was called, "Separation Process Principles", by J. D. Seader and E. J. Henley, John Wiley & Sons (1998). It was pretty thorough about the different methods of chemical separations. It covers cascading towers, flash chambers, and membrane separations (to name a few).

try searching for a sensible technological expertise communicate board quite than asking idiots on Yahoo solutions - believe me you do not have alot of experts on Yahoo, Alot of scientific solutions on Yahoo are BULLSHIT
