Abstract: Aspects of the innovations presented herein relate to improved systems that in some embodiments perform capillary electrophoresis (CE) and CE in conjunction with electrospray ionization (ESI) as an input to a mass spectrometry system (MS). Some embodiments use a high voltage isolated CE power supply that is configured to float on the high voltage output of an ESI-MS power supply, with a protective resistance in the ESI-MS path, as well as DC/DC converter isolation and communication system isolation for the isolated CE power supply. Some embodiments additionally use a cartridge assembly integrating separation and conductive fluid capillaries with fluid cooling and protective retractable housings for the capillary end portions and for the ESI output. The protective housing may further be used with an adapter for interfacing with different MS systems.

Abstract: An apparatus and method for supplying operating voltages to a plurality of electronic devices is disclosed. A plurality of power supply modules of a modular power supply may output voltages to at least two electronic devices. The apparatus may identify a failure of one of the power supply modules. The electronic device may be disconnected from the failed power supply module, and then reconnected to a functional power supply module of the modular power supply. A supplied voltage of the functional power supply module of the modular power supply may be varied, such as wherein the supplied voltage matches the set output voltage of the failed power supply module.

Abstract: A process for separating from an oil sand slurry solids and bitumen is provided, comprising introducing the oil sand slurry into a separation zone comprising an upper zone and a lower zone; intercepting a settling path of the solids in the separation zone by bringing the solids into contact with at least one intercepting surface to direct the solids to the lower zone; and producing a reduced solids upper zone to allow the bitumen to rise through the upper zone with reduced hindrance from the solids.

Abstract: A process for removing contaminants, namely water and particulate solids, from hydrocarbon diluent-diluted bitumen froth (“dilfroth”) is provided to produce hydrocarbon diluent-diluted bitumen (“dilbit”), comprising subjecting the dilfroth to gravity settling in a primary settler to produce an overflow stream of primary raw dilbit, comprising bitumen containing water and some fine solids, and an underflow stream of primary tails, comprising solids, water and residual bitumen; removing the overflow stream of primary raw dilbit and subjecting it to gravity settling in a clarifier vessel for sufficient time to produce an overflow first stream of cleaned dilbit and an underflow stream of clarifier sludge; diluting the primary tails with hydrocarbon diluent and subjecting the diluted primary tails to gravity settling in a secondary settler to produce an overflow second stream of cleaned dilbit and an underflow stream of secondary tails; and removing the clarifier sludge and diluting the clarifier sludge with a hyd

Abstract: A load sensor includes a housing and a magnet carrier axially movable within the housing. A first and a second magnet are coupled to the magnet carrier in an axially spaced apart arrangement and oriented to provide repelling magnetic fields. The magnet carrier and the first and second magnets are axially movable relative to the magnetic field sensor, and the magnetic field sensor is configured to provide an output that is indicative of the position of the magnetic filed sensor relative to the first and second magnets.

Abstract: Diluent-diluted bitumen froth containing bitumen and naphtha diluent, hydrocarbons, water, sand and fines (collectively “dilfroth”) is fed into a vapor-tight gravity settler (‘splitter’) and temporarily retained to produce a bottom layer of tails comprising sand and middlings, a rag layer of discrete three-dimensional structures, each comprising hydrocarbons contained in a skin of fines, and a top layer of hydrocarbons containing small droplets of water and fines (‘raw dilbit’). The flux in the splitter is less than 6 m3/h of dilfroth fed per m2 of horizontal cross-sectional rag area. The in-coming dilfroth is fed directly into the splitter middlings. Demulsifier is added to the overflow stream of raw dilbit and the mixture is subjected to prolonged settling in a vapor-tight polisher tank, to produce polished dilbit containing less than 1.0 wt. % water and 0.3 wt. % solids. The splitter underflow tails, containing less than 15 wt.
