Title: Oxidation treatment of a recycle stream in production of acetic acid by methanol carbonylation
Inventor: HUCKMAN MICHAEL E
IPC: C08F8/00
Filed: 2003-03-10
Abstract: A method and system is provided for producing acetic acid by the catalytic carbonylation of methanol with carbon monoxide to obtain a reaction product stream comprising acetic acid and a minor amount of acetaldehyde. The acetaldehyde content in the reaction product stream is reduced by oxidation to convert at least a portion or the acetaldehyde in the stream to acetic acid or further to CO2 and H2O. The oxidized stream may then be directed to the purification section, the reaction section, or both whereby the deleterious effects of acetaldehyde are reduced. Advantage of the present invention over conventional process is the reduced need to dispose of acetaldehyde as waste and improved overall system efficiency in the production of acid.

Patent CA-2486428-A1 (CA)
Title: Magnetic condensing system for cryogenic engines
Inventor: MINOVITCH MICHAEL A
IPC: H01F1/00
Filed: 2003-05-16
Abstract: A method and apparatus is provided for generating an artificial heat sink below ambient temperature for a cryogenic condenser (32) by isothermally magnetizing a paramagnetic fluid and removing the magnetic field, thereby creating a temperature drop in the fluid by the magentocaloric effect. The heat of magnetization is converted into mechanical work by initially placing the fluid inside a sealed chamber (80) with a door (76) that opens to a conduit (70) leading into the bore of a superconducting solenoid (72). When the solenoid (72) is energized, it creates a strong axial magnetic field that exerts magnetic attractive forces on the fluid. When the fluid is released by opening the door (76), it is accelerated through the conduit (70) toward the superconducting solenoid where it becomes magnetized by the increasing strength of the magnetic field. By mounting a non-magnetic turbine (120) inside the conduit between the solenoid and the chamber, the kinetic energy of the accelerating flow stream, which is equal to the heat of magnetization, is converted into mechanical work, thereby achieving isothermal magnetization. By removing the magnetic field after the fluid enters the bore of the solenoid, a temperature reduction is achieved thereby enabling the fluid to absorb heat in a cryogenic condenser.
