Abstract: The system implements a hybrid marketplace model that takes the best attributes of both “push” and “pull” based marketplace platforms. Ride requests are submitted by ride organizers and prioritized based on driver preferences and qualifications. These are then presented to drivers in an app where they can build their daily and weekly schedule, claiming the trips most desirable for them. This gives drivers the flexibility they are looking for and gives ride organizers the ability to share driver/vehicle information with their children ahead of time (giving kids comfort on who is picking them up). Meanwhile, there is also an automated system that monitors unclaimed trips (or trips that had a last-minute driver cancel), automatically adjusts the payout to a driver, and sends automated outbound messages informing drivers of a family in need. This “push” portion of the platform ensures the system will not leave a child stranded without a ride.

Abstract: The system is an integrated solution that provides end-to-end visibility for 3rd party observers (parents, school administrators, socials workers, etc.), and system safety personnel (“Safe Ride Support Specialists”) to monitor each trip in real-time for safety related anomalies. These incidents generate alerts that are prioritized and distributed to the appropriate party to take action through a combination of automated and manual processes. An advantage of the system is that it does not require the passenger to have a cell phone or other mobile device. In addition, the system is active instead of passive, with alerts being issued to observers in response to certain triggers. In addition, the system can take automated actions to preserve passenger safety.

Abstract: Apparatuses, systems and methods for separating highly pure unsaturated olefinic hydrocarbon stream with zero cooling water and or steam consumption, with minimum possible capital investment and uncompromised operational ease are disclosed herein from a mixture of hydrocarbon stream consisting of saturated and unsaturated hydrocarbons. Embodiments of the invention are directed to producing a hydrocarbon stream containing polymer, chemical grade ethylene, propylene, butylenes, isoprene, hexane stream which are of value in manufacturing chemicals, polymers, and rubbers. Embodiments of the process provided can be applied to concentrating ethylene, propylene, butylenes, cyclopentadiene, isoprene, 2 methyl butene-2, isopentane, hexene etc.

Abstract: A process is presented to treat a process stream containing a hydrocarbon (oil and/or gas) and hydrogen sulfide with a liquid treatment solution containing a sulfur dye catalyst. The process stream can be within a pipeline, wellbore, subsea pipeline or a wellhead that contains hydrogen sulfide where the liquid treatment solution is injected at a predetermined point to define a scavenger zone such that the sulfur dye catalyst in the liquid treatment solution causes the sulfide from the hydrogen sulfide to react with the catalyst. The hydrocarbon component is separated substantially free of the hydrogen sulfide from a spent treatment solution containing spent sulfur dye catalyst which can then be fed to an oxidation vessel where it is contacted with an oxygen containing gas causing the sulfide to oxidize to thiosulfate and converting the spent sulfur dye catalyst to regenerated sulfur dye catalyst.

Abstract: A process for the distillative separation of ethylbenzene from a mixture comprising ethylbenzene and at least one other C8 aromatic compound, comprising introducing a feed stream comprising said mixture into a first distillation column, introducing a first stream comprising a heavy solvent above the feed stream into the first distillation column, introducing an aqueous stream below the feed stream into the first distillation column.

Abstract: Apparatuses, systems and methods for producing Pips stream for manufacturing catalytic C5 hydrocarbon resins containing all the key reactive monomers that are already present in the C5 fraction of the pyrolysis gasoline, which is otherwise lost with the crude isoprene stream, are disclosed herein. Embodiments of the invention are directed to producing a hydrocarbon resin grade DCPD stream consisting of dimers and codimers of isoprene which are of value in manufacturing thermal hydrocarbon resins, either polymer grade isoprene and gasoline quality raffinate (free or sulfur and acetylenes) or a relatively small crude isoprene stream with maximum utilization of isoprene by moving some of the isoprene to a DCPD stream used to manufacture thermal hydrocarbon resins.

Abstract: Apparatuses, systems and methods for separating heavy hydrocarbons from a solvent stream are disclosed. The heavy hydrocarbons and solvent can be recovered and processed further.

Abstract: The claimed invention provides a technique wherein the two column system is combined into a single column. The light components are concentrated on the prefractionation side (feed side) of the column, where they are removed as an overhead top product. The middle boiling components are removed as an overhead product on the opposite side of dividing wall. For the same product specifications, top divided column requires substantially lower capital and operating cost than a conventional two-column system.

Abstract: An insect repellent material includes a carrier such as a polyethylene, a molecular sieve or zeolite material, and a repellent such as geraniol. The molecular sieve/zeolite material provides the insect repellent material with a slow-release quality and also permits the carrier to hold more insect repellent than it would otherwise if so desired.
