A devolatilizer (devo), which operates at a temperature (T) and at a pressure (P), for the separation of at least a portion of a solvent from a polymer-rich solution comprising the solvent and a polymer, and wherein the devolatilizer comprises at least the following components:

Devolatilizer design

Phosgene is mixed with an organic polyamine to produce polyisocyanate compounds. A phosgene flow is established in a conduit (), and the organic polyamine is injected into the phosgene flow. A constricted region () of the conduit () resides downstream of the point of the polyamine injection. The presence of the constricted region () reduces by-product formation.

Static mixing device and method for mixing phosgene and an organic amine

A fired heater with a film temperature optimizer is presented. The fired heater is for heating a process fluid in process coils within the fired heater. The process coils experience high temperatures at the outlets. The film temperature optimizer includes baffles or means for changing the flow of the fired heating gas around the process coils near the coil outlets. The baffles are positioned near the process coil outlets.

Film temperature optimizer for fired process heaters

A process and apparatus is disclosed for distributing a gas stream into a downwardly flowing catalyst stream in a vessel by feeding the gas stream into a center of the vessel or the catalyst stream into a hollow cap. The gas stream enters the cap and exits the cap flowing upwardly to contact the catalyst stream.

Apparatus and process for contacting catalyst with a gas and reduction

An apparatus for heating a process fluid is presented. The apparatus is for improving the foot-print of a fired heater and to reduce the fired heater volume. The apparatus includes a W-shaped process coil to provide for a smaller single-cell fired heater, and a fired heater with a lower profile, providing flexibility in positioning relative to downstream reactors.

Reactor and heater configuration synergies in paraffin dehydrogenation process

An apparatus for a fired heater is presented. The fired heater is designed with process coils inside a shell, and with a positioning of the burners for reducing the size of the fired heater. The shell has a general rectangular prismatic shape with combustion inlets for admitting combustion gases from the burners, and the process coils include at least two inlet ports and at least one outlet port.

Process fired heater configuration

An apparatus for a fired heater is presented. The fired heater is designed with a plurality of process coils inside a shell, and with a positioning of the burners for reducing the size of the fired heater. The shell has a general rectangular prismatic shape with combustion inlets for admitting combustion gases from the burners, and the process coils include at least two inlet ports and at least one outlet port.

Alternative coil for fired process heater

A baffle is installed on the wall of a regenerator vessel to push catalyst away from the wall to ensure adequate exposure to regeneration gas and complete combustion of coke from the catalyst. We have found that in deep beds, catalyst can flow down the walls and escape sufficient exposure to regeneration gas and undergo too little regeneration.

Apparatus for regenerating catalyst

A unit for processing a liquid/gas phase mixture, a mercaptan oxidation apparatus, and a method of processing a liquid/gas phase mixture are provided. In an embodiment, a unit for processing a liquid/gas phase mixture includes a vessel that is adapted to receive the liquid/gas phase mixture and a distributor that is disposed in the vessel. The distributor is adapted for flow of the liquid/gas phase mixture into the vessel, and the distributor includes a first outlet pipe that is horizontally disposed within the vessel. The first outlet pipe includes top orifices and bottom orifices that are spaced along the first outlet pipe, and the first outlet pipe is in fluid communication with the vessel through the top orifices and the bottom orifices. The top orifices have a smaller cross-sectional area than the bottom orifices.

Unit for processing a liquid/gas phase mixture, mercaptan oxidation system including the same, and method of processing a liquid/gas phase mixture

An apparatus for use in radial flow reactors is presented. The apparatus includes a first partition and a second partition with support members coupled therebetween. The first partition include a first opening and a second opening to allow the passage of fluid therethrough. A baffle extends into a flow channel formed by adjacent support members to obstruct an upper or lower portion of the first opening to interrupt a portion of the fluid flow therethrough.

Apparatus for retaining solid material in a radial flow reactor and method of making

The present invention relates to a tube-side sequentially pulsable-flow, shell-and-tube heat exchanger apparatus and a chemical processing system comprising and methods of heat exchange employing the same.

Tube-side sequentially pulsable-flow shell-and-tube heat exchanger appratus, system, and method

An inclined baseplate for a radial bed reactor improves solids flow from the bottom of the reactor. Gas flow can be improved by utilizing an aerated baseplate or by providing a non-porous section of outer perforated cylinder in the area below the level of the bottom of the inner perforated cylinder.
