Abstract: Processes for the production of high purity isobutylene are disclosed. The processes may include supplying a mixed C4 feed stream to a catalytic distillation column, which may contain a butene isomerization catalyst. 1-butene is isomerized to 2-butene and concurrently in the catalytic distillation column the 2-butene is separated from the isobutane and isobutylene. The overheads fraction comprising the isobutane and isobutylene is then condensed in an overheads system and fed to a splitter, where the isobutane is separated from the isobutylene. The process further includes operating the catalytic distillation column at an overheads temperature greater than a bottoms temperature of the splitter, and heating a portion of the splitter bottoms stream via indirect heat exchange with at least a portion of the catalytic distillation column overheads fraction, thereby producing a heated bottoms stream (reboil vapor) fed to the splitter and a cooled overheads fraction.

Abstract: A user input that includes a final destination and one or more user criteria is received. One or more available paths that satisfy the one or more user criteria are determined by utilizing mapping data. The one or more available paths are displayed within an electronic device. A user selection of a desired path of the one or more available paths is displayed. The user-selected desired path is displayed within a user interface. Traffic data and user data are monitored. A routing event is detected based on monitoring the traffic data and the user data. One or more new paths that satisfy the criteria are generated, based on the monitored traffic data and user data. A user is prompted to select one of the one or more generated new paths. A user selection of at least one of the one or more generated new paths is received.

Abstract: Methods, systems and computer program products for determining and providing an availability status of an individual in an open working environment are provided. Aspects include obtaining historical usage data, communication data, calendar data, and statuses set data from selected network-connected devices used by the individual, and calculating a current availability status for the individual based on the historical usage data, the communication data, calendar data, and the statuses set data. Aspects also include calculating a predicted future availability status for the individual based on the historical usage data, the communication data, calendar data, and the statuses set data, and visibly displaying proximate the individual's workspace the current availability status and the predicted future availability status to others in the open working environment.
