摘要： An aromatics complex producing one or more xylene isomers offers a large number of opportunities to conserve energy by heat exchange within the complex. One previously unrecognized opportunity is through providing two parallel distillation columns operating at different pressures to separate C8 aromatics from C9+ aromatics. The parallel columns offer additional opportunities to conserve energy within the complex through heat exchange in associated xylene recovery facilities.

摘要： A process for recovering waste heat in an organic Rankine cycle system which comprises passing a liquid phase working fluid through heat exchange in successive communication with two or more process streams which thus heat the working fluid, removing a vapor phase working fluid from the heat exchanger, passing the vapor phase working fluid to an expander wherein the waste heat is converted into mechanical energy, and passing the vapor phase working fluid from the expander to a condenser wherein the vapor phase working fluid is condensed into the liquid phase working fluid.

摘要： An apparatus is disclosed for recovering product from catalytically converted product streams. Gaseous unstabilized naphtha from an overhead receiver from a main fractionation column is compressed in a compressor. Liquid unstabilized naphtha from the overhead receiver and liquid naphtha fraction from the compressor are sent to a naphtha splitter column upstream of a primary absorber. Consequently, less naphtha is circulated in the gas recovery system.
