Granted: 2003-01-07
Abstract: This invention relates to an arrangement for efficiently providing an up to date neighbor list for base stations serving a wireless cellular telecommunications call. The neighbor list is required by a mobile station measuring signal strengths of signals for surrounding base stations in order to locate base stations from which the mobile station can receive strong signals. When one base station receives a revised neighbor list from another base station, it receives a revised neighbor list from another base station, it receives a time stamp identifying when that revised neighbor list was created. Thereafter, when a request for data from a base station is transmitted, it is transmitted with that time stamp; no neighbor list is returned if the time stamp matches the time stamp stored with the neighbor list of the base station receiving the request.

Abstract: A method of treating produced water from heavy oil production to provide feedwater for the production of high quality steam. A produced water from heavy oil recovery operations is initially treated by first removing oil and grease to a desired level, preferably to about twenty parts per million, or less.    The pH is then adjusted, normally downward and by acid addition, to release at least some carbonate alkalinity as free carbon dioxide. Preferably, all non-hydroxide alkalinity is removed, or substantially so, by introducing the feedwater into a decarbonator. In some cases, the pH may be raised (without, or subsequent to decarbonation, depending upon water chemistry) preferably by caustic addition, to maintain silica solubility in the feedwater. Next the feedwater is introduced into an evaporator, and the feedwater is evaporated to a pre-selected concentration factor to produce (1) a distillate having a small amount of residual hardness therein, and (2) a concentrate containing residual solids (dissolved solids and in some cases, suspended solids). The distillate is then cooled, and is subsequently introduced into a hardness removal step, preferably an electrodeionization (EDI) treatment unit, to remove the residual hardness from the distillate. Finally, the substantially hardness free treated water stream is sent to packaged boilers, for production of high quality steam.    The hardness containing stream from EDI is recycled to the evaporator feed, for further treatment.
