Title: Quench water pretreat process
Inventor: KURUKCHI SABAH
IPC: B01D17/04
Filed: 2002-02-12
Granted: 2008-05-20
Abstract: A process for pretreating a oily/water stream for closed loop dilution steam production within an ethylene plant using countercurrent multi-stage extraction to remove both free and dissolved organic solutes from in-situ (net) quench water with an organic solvent to yield an aqueous raffinate containing only residual amounts of organic solute.  The raffinate is steam stripped to remove the residual organic solutes, yielding a pretreated quench water stream substantially of organic material. The pretreated quench water is suitable for reuse to generate dilution steam (without fouling). The (solvent) extract from extraction is regenerated in a solvent regenerator having an overhead stream for purging light ends, a bottom stream for purging heavy ends, and a heart-cut side stream for recycling solvent to the extractor. Alternatively, solvent may be taken as a heart-cut or equivalent from an existing ethylene and/or refinery plant process stream, once passed through the multi-stage solvent extraction unit, and then returned to the processing unit of the plant from which it was taken.

Granted: 2006-11-21
Abstract: The invention relates to jet device used for extracting oil from wells. The inventive method consists in the following: a pump, a connecting and disconnecting unit, a valve unit, a packer and a shank are mounted on a tubi ng string before actuating the inventive device. A perforator is run into the well on a mounting seat in the pass channel of the pump, the packer being released. Differential pressure being produced, the perforator is blasted against the productive stratum which is then drained. The perforator being replaced by the transmitter and receiver-transducer of physical fields, the stratum is studied while the pump operates. Said transmitter and receiver- transducer being pulled from the well, a valve chamber and a blocking insert separating the cavity of the tubing string from environment are thrown into the well. The well starts to work in a natural flow regime. When the production rate decreases, the well is suspended, the blocking insert is substituted by a depression insert provided with a manometer and a debitomet er and the well production is measured while fluids are pumped out. The flow ra te- bottomhole pressure graph is plotted according to indications of instruments and interpreted, thereby defining the sizes of a pump. The required pump is run into the well along the tubing string and the well is put into operation by a power method. The invention is directed to improve reliability of the operation of said device.

Title: System for delivering data over a network
Inventor: CHEUNG KWOK-WAI
IPC: H04N7/173
Filed: 2002-07-29
Granted: 2010-02-16
Abstract: This invention describes a new method and system for delivering data over a network to a large number of clients, which may be suitable for building large-scale Video-on-Demand (VOD) systems. In current VOD systems, the client may suffer from a long latency before starting to receive the requested data that is capable of providing sufficient interactive functions, or the reverse, without significantly increasing the network load. The method utilizes two groups of data streams, one responsible for minimizing latency while the other one provides the required interactive functions. In the anti-latency data group, uniform, non-uniform or hierarchical staggered stream intervals may be used. The system of this invention may have a relatively small startup latency while users may enjoy most of the interactive functions that are typical of video recorders. Furthermore, this invention may also be able to maintain the number of data streams, or the bandwidth, required.
