ABSTRACT:
Apparatus and processes are disclosed for converting sensitive organic compounds such as acrolein, methacrolein, acrylic acid and methacrylic acid from liquid to vapor in admixture with a gas stream at super-atmospheric pressures with minimum decomposition and substantially without polymer formation. The acrolein and methacrolein partial pressures being up to super-atmospheric and those of acrylic and methacrylic acids up to about an atmosphere.
An apparatus and a process are also disclosed for transferring a sensitive organic material in an energy-efficient manner from a low-pressure, high-temperature gas-vapor stream to a solvent for the sensitive material, and then to another gas stream at increased pressure.
