Malamas Caracotsios

A method for the control of a polymerization process, which method employs the combination of a densitometer measurement of the polymerization reaction mixture and a quadratic computer model.

Monomer concentration prediction and control in a polymerization process

A method for solution polymerizing ethylene wherein an ethane purge stream is separated, subjected to high efficiency cryogenic distillation, and a side cut from that distillation recycled to the polymerization process while the overhead and bottoms from that distillation are removed from the polymerization process.

Ethylene recovery from a polymerization process

A method and apparatus for operating a pressure vessel containing a bed of particulate material comprising substantially leveling the bed and employing a plug-flow inducer in the bed.

Plug-flow method and apparatus for operating a curvilinear pressure vessel where transport phenomena occur

A method and apparatus for operating a pressure vessel containing a bed of particulate material comprising substantially leveling the bed and employing a fluid flow distributor above the bed.

Residence time distribution method and apparatus for operating a curvilinear pressure vessel where transport phenomena take place

An advanced control method is disclosed for the polymerization of an alpha-olefin in a substantially horizontal, quench-cooled, stirred bed reactor.
