    摘要： A process for the recovery of glycerol comprises contacting an aqueous feed composition that comprises water, glycerol, and at least one contaminant with a solvent extractant comprising at least one C5-C8 alkanol, optionally in admixture with at least one alkane, to form a first mixture, and separating the first mixture into a first solvent phase and a first aqueous phase. The first solvent phase comprises a majority (more than 50 wt %) of the solvent extractant and a majority of the glycerol that was present in the aqueous feed composition. The weight ratio in the first solvent phase of glycerol to a contaminant present is greater than the weight ratio of glycerol to the contaminant in the aqueous feed composition. The first aqueous phase comprises a majority of the water from the aqueous feed composition and at least some of the contaminant from the aqueous feed composition.

    摘要： A subsea intervention system is disclosed comprising a floating vessel and a source of coiled tubing at the floating vessel. The system includes a seabed installation including a wellhead and compliant guide having one end operatively connected to the floating vessel and the second end operatively connected to the seabed installation. The compliant guide provides a conduit between the floating vessel and the wellhead for the coiled tubing. At least one injector is present at the floating vessel for inserting the coiled tubing into the compliant guide, and a carousel is proximate the wellhead which comprises a plurality of chambers with intervention tools in at least two of those chambers. The system may also include a plurality of sensing units that are disposed at spaced intervals along the compliant guide to monitor various aspects of the compliant guide and to transmit that information to a repositioning system. A riser may be used instead of the compliant guide.

    摘要： The invention relates to methods and devices that enable to request more than one service during call set-up. To this end a new indicator is introduced into a request message sent to a database storing subscriber data, for indicating that at least one further request message is sent and a response indicator that a database is adapted to handle said indicator. Furthermore a set of rules is defined how different responses from the database are processed to enable said request.

    摘要： The present invention provides a method for producing sucralose from a feed stream including a sucrose-6-acylate in a reaction vehicle. The method includes: (i) reacting the sucrose-6-acylate with a chlorinating agent in order to chlorinate the 4, 1′ and 6′ positions of the sucrose-6-acylate; (ii) quenching the product stream of (i) with an aqueous solution of a base to provide a sucralose-6-acylate and the chloride salt of said base, wherein the concentration of the aqueous solution of the base is sufficiently high such that at least a portion of the chloride salt of the base is formed as a precipitate; (iii) either: deacylating the sucralose-6-acylate by treating the product stream of (ii) with a base and thereafter removing precipitated salt to provide a product stream including sucralose; or: removing precipitated salt from the product stream of (ii) and thereafter deacylating the sucralose-6-acylate by treating with a base to provide a product stream including sucralose; and (iv) isolating sucralose from the product stream of (iii).
