A method and system for modulating vapor and liquid fractions of a cycling liquid-vapor fluid operating within its phase transition envelope by creating forced oscillating heat transfer between liquid and vapor fractions of the cycling stream.

This document discloses a system and method for separating cracked hydrocarbon mixtures. A main fractionation column separates the cracked hydrocarbon mixture into top, side, and bottom fractions containing C1 to C6+ hydrocarbons. A top condenser and high-pressure separation system partially condenses the top fraction and compresses the uncondensed vapor to produce a compressed gas fraction and a compressed liquid fraction. A first distillation column receives the compressed liquid fraction and separates it into a first top vapor and a first bottom fraction. A second distillation column separates the first bottom fraction into a second top fraction and a second bottom fraction. An absorber receives a portion of the second bottom fraction and the side liquid fraction and contacts it in countercurrent flow with the compressed gas fraction, thereby producing an absorber top fraction and absorber bottom fraction containing exhaust gas. Such a system can be used to integrate existing FCC / RFCC units with petrochemical complexes.

Methods for separating a first material flow containing a dissolved substance are already known in which said first material flow is divided into a second material flow and a third material flow such that the third material flow has an increased concentration of the dissolved substance compared to the second material flow. In such methods, this is achieved by means of a freezing process in which the first material flow is pre-cooled in a heat exchanger and solidified in a heat pump, whereupon the ice is mechanically crushed and centrifuged, allowing the extraction of a liquid fraction containing the dissolved substance which does not integrate into the ice lattice. In such a method, the invention provides a second heat pump which only takes over the heat transfer in the region of the freezing point, meaning that its efficiency is particularly high due to the substantially constant temperature on both sides.
