Abstract: A housing for a single-pole circuit breaker is disclosed. The housing includes two current path regions, each region having a first section configured to receive an electromagnetic protection device, a second section configured to receive a thermal protection device, a third section configured to receive an arc extinguishing device, and a fourth section configured to receive an operating mechanism device. Each first section occupies a substantial part of the available internal width of the housing, and is disposed between the respective third and fourth sections. Each second section occupies about half the available internal width of the housing.

Abstract: Method of and apparatus for multi-phase contact utilizing louvered structured packing. The packing is provided in corrugated sheets and between the fold lines of the corrugations; a plurality of large louvered openings are disposed in generally parallel spaced relationship. An array of small louvers is disposed between the large louvers. Each of the louvers is oriented for selectively vectoring a liquid-liquid or liquid-vapor around and through the corrugated sheets when disposed within a process tower.

Abstract: A downcomer tray assembly for vapor liquid contact towers. The region of the tray beneath an upper downcomer is constructed with a raised, perforated region for improving mass transfer efficiency. The raised region reduces fluid pressure to vent excess vapor from the underlying tray. The vented vapor is selectively directed into the liquid discharged from the downcomer and imparted with a horizontal flow characteristic. In this manner both entrained liquid and entrained gas can be effectively released to facilitate a stabilized vapor-liquid flow configuration.

Abstract: A downcomer tray assembly for vapor liquid contact towers. The region of the tray beneath an upper downcomer is constructed with a raised, perforated region for improving mass transfer efficiency. The raised region reduces fluid pressure to facilitate ascending vapor therethrough. A series of louvers selectively directs the upward vapor flow into the liquid region below the downcomer to generate a more efficient vapor-liquid contact and reduced back-mixing across the tray.

Abstract: A delayed coking process and a solvent deasphalting process are combined so that an asphalt mix of asphalt and solvent from the solvent deasphalting process is sent as feedstock to the delayed coking process to form coke and intermediate hydrocarbon vapor and liquid products. The vaporization of the solvent in a delayed coker heater assists the flow of the asphalt mix through the heater, and a portion of the asphalt mix is directed to a delayed coking fractionator so that the flow of solvent through the delayed coking heater can be adjusted by varying the relative amounts of asphalt mix sent to the delayed coker heater and to the fractionator. A deasphalted oil mix of deasphalted oil and solvent from the solvent deasphalting process is heated by hotter fluid products from a fractionator in the delayed coking process, and makeup solvent to a solvent deasphalting section is heated by vapors in the fractionator overhead.
