Abstract: A process and apparatus integrate recovery of propylene from a pyrolysis reactor and a paraffin dehydrogenation reactor. The improved process for recovering light olefins utilizes heats of compression to heat reboil streams.

Abstract: A process and apparatus integrate recovery of propylene from a pyrolysis reactor and a paraffin dehydrogenation reactor. A common C3 splitter column fractionates propylene product from propane recycle to a paraffin dehydrogenation reactor. The C3 hydrocarbons may be provided from a pyrolysis reactor and from a dehydrogenation reactor.

Abstract: A process and apparatus integrate recovery of propylene from a pyrolysis reactor and a paraffin dehydrogenation reactor. A common depropanizer fractionates propane feed and pyrolysis reactor effluent to provide a C3 stream. A dividing wall may be used in the column to prevent cross contamination by the pyrolysis effluent with the propane dehydrogenation feed.

Abstract: A process and apparatus cool a pyrolyzed stream and a dehydrogenated stream in respective cold boxes by use of a refrigerant compressed with a common compressor. The refrigerant is compressed and used to cool a pyrolysis cold box and a dehydrogenation cold box.

Abstract: A process and apparatus integrate recovery of propylene from a pyrolysis reactor and a paraffin dehydrogenation reactor. A stripping column for fractionating a dehydrogenation stream is coupled with a demethanizer column for fractionating a pyrolyzed stream. The stripping overhead stream comprising C2? hydrocarbons are fractionated with the pyrolyzed stream in the demethanizer column. The coupling omits the need for a conventional deethanizer column and separate refrigeration system in the propane dehydrogenation unit.

Abstract: Inhibitors of SARS-COV-2 (COVID), pharmaceutical compositions comprising same; and methods of treating a severe acute respiratory syndrome.

Abstract: Embodiments pertain to a system with a first surface and a second surface operational to associate with one another, where at least one of the first surface and the second surface includes an adhesive layer and a graphite layer positioned on the adhesive layer, and where the graphite layer reduces friction between the first surface and the second surface while the adhesive layer maintains the position of the graphite layer on at least the first surface and the second surface. Additional embodiments pertain to methods of modifying a system that includes a first surface and a second surface by applying an adhesive material to at least one of the first surface and the second surface to form an adhesive layer on at least one of the first surface and the second surface; and applying a graphite material onto the adhesive layer to form a graphite layer on the adhesive layer.

Abstract: Bis-amide inhibitors of SARS-CoV-2 (COVID) and methods of using them to treat a severe acute respiratory syndrome.

Abstract: A transparent proxy for malware detection includes a monitor module, a protocol determination module, a challenge generation module, a response determination module, and a data control module. The monitor module examines data originating from an application towards a remote server. The protocol determination module identifies the protocol type used for the data. The challenge generation module produces a challenge for the application based upon the protocol type, sends the challenge to the application, and maintains a state related to the data and the challenge. The response determination module makes a determination if an automatic non-interactive application response is received in response to the challenge from the application. The data control module allows the first data to continue to the remote server when the determination is valid. The data control module reports malware detection and blocks the data to continue to the remote server when the determination is invalid.
