Abstract: An application launching user interface that includes a plurality of application icons for launching corresponding applications is displayed. A first touch input is detected on a first application icon of the plurality of application icons. The first application icon is for launching a first application that is associated with one or more corresponding quick actions. If the first touch input meets one or more application-launch criteria which require that the first touch input has ended without having met a first input threshold, the first application is launched in response to the first touch input. If the first touch input meets one or more quick-action-display criteria which require that the first touch input meets the first input threshold, one or more quick action objects associated with the first application are concurrently displayed along with the first application icon without launching the first application, in response to the first touch input.

Abstract: A process and apparatus reboil a propylene splitter bottoms by heat exchange and/or a deethanizer bottoms stream with a compressed propylene splitter overhead stream. Use of single splitter compressor and operation of the propane-propylene splitter column at lower pressure are enabled, whereas conventionally two splitter compressors and higher splitter pressure were necessary to provide a propylene product stream and a propane recycle stream of equivalent quality.

Abstract: A process and apparatus integrate a deethanizer column with a cryogenic heat exchanger by reboiling the deethanizer column with a refrigerant stream and/or cooling a deethanizer overhead line in the cryogenic heat exchanger. A single stage separator and a single deethanizer column may be used to obtain high purity hydrogen in the net gas stream and an ethane rich off-gas stream, whereas conventionally a dual stage separator and two deethanizer columns were necessary for equivalent purity, respectively.

Abstract: Systems and processes for heat recovery associated with the separation of hydrocarbon components. Two compressors are used to compress a portion of an overhead vapor stream from a fractionation column. A pressure of the liquid portion of the compressed overhead is reduced and used to recover heat from an overhead of another separation zone having a fractionation column. Once the heat has been recovered the stream is recompressed. The recovered heat may be removed from the recompressed stream in a reboiler of another fractionation column. The fractionation columns may comprise a deethanizer stripper, propane-propylene splitter, and a depropanizer column.

Abstract: A process for recovering heat from the separation of hydrocarbons. The overhead vapor stream from a fractionation column is passed to a two stage heat pump compressor. The first stage of compression is used to reboil the fractionation column. The second stage is compressed and cooled passed to a separation zone. The liquid in the separation zone may be passed back to the fractionation column as secondary reflux, and/or recovered as liquid product. Heat may also be removed from the second stage. A suction drum on the first stage may be used to protect the heat pump compressor from any droplets in the overhead stream.

Abstract: Fractionation systems utilizing a single rectifying column with a stripping column housed in the same vessel and having a uniform diameter are described. Methods of separating feed streams using the fractionation systems are also described.

Abstract: Fractionation systems utilizing a rectifying column with a stripping column are described. The liquid from the rectifying column bottoms is sent to the first tray of the stripping column, while the overhead stream from the stripping column is sent to the bottom of the rectifying column. Processes for separating feed streams are also described.

Abstract: A simulated collaborative mix workload for determining the performance of enterprise software includes a combination of mail, instant messaging, electronic meetings, documents, and electronic learning. The workload is generated by executing a team spaces path, documents path, learning path, messaging path, web conference path, or various combinations thereof. The team spaces path generates a simulated discussion with team members and generates a search query for locating a forum within the team space. The documents path generates a library search to locate, open, and read the document, and generates a simulated chat about the document. The learning path launches a simulated course and assessment activity. The messaging path reads a simulated email, attaches a document thereto, and sends the email. The web conference path generates a web conference attended by a plurality of simulated users. At least one of the workload tasks is performed more than once.
