摘要:
An apparatus designed to completely vaporize an intake of heavy hydrocarbon feedstock is described. The apparatus, a so-called heavy feed mixer, is comprised of pipes being disposed coaxially about a common longitudinal axis. The inner tubular section delivers a two-phase liquid-vapor mixture of hydrocarbon feedstock and dilution steam to the apparatus. The converging/diverging tubular section has a unique structure which converges to a throat section and then diverges to an outlet section. The converging section directs a uniform shroud of superheated steam onto the hydrocarbon stream delivered by the inner tubular section. Impingement of the superheated steam with the intake stream initiates mixing and further vaporization within the throat section. The mixture traverses the converging/diverging tubular section and passes into the outlet section where vaporization is complete. The completely vaporized stream is directed out of the apparatus for further processing downstream.

Die Erfindung betrifft eine Vorrichtung zum Verdampfen von Flüssigkeiten, mit einem mit einer Heizung (8, 15, 16) beheizbaren Verdampfer, bei dem in einem Verdampfergehäuse (1) mit einem Einlass (3) und einem Auslass (5) ein Porenkörper (2) aufgenommen ist. Zur Verbesserung der Dynamik des Verdampfers sowie zur Vermeidung von unerwünschten Pulsationen bei der Dampfherstellung wird erfindungsgemäß vorgeschlagen, dass eine Kühleinrichtung (13) zum Kühlen eines einlassseitigen Abschnitts (A1) des Verdampfergehäuses (1) vorgesehen ist.

Disclosed herein is a delivery device comprising a chamber; a gas inlet; a gas outlet; and a dip tube contained within the chamber and having an upper portion and a lower portion, the upper portion of the dip tube being in fluid communication with the gas inlet and being operative to permit the entry of a carrier gas; the lower portion of the dip tube extending into the chamber, the lower portion of the dip tube terminating in an outlet end; and a sleeve; where the sleeve has a first end and a second end; the first end being in an interference fit with the lower portion of the dip tube; and where the sleeve vibrates upon being subjected to a disturbance.
摘要:
Liquid is flash evaporated in a series of cells along and surrounding an exhaust duct to generate a pressurized vapor where at least one of the surfaces is in communication with the source of heat sufficient to maintain the surface at a temperature such that the liquid injected into the chamber is substantially instantly converted to a superheated vapor with no liquid pooling within the chamber. The liquid is introduced by controlled injectors operating at a required rate. Each of the cells is periodically discharged by a pressure controlled relief valve and the vapor from the cells combined to form a continuous stream feeding a turbine or other energy conversion device. The outer wall of the cell is offset so that it contacts the inner wall at one point around the periphery. Heat transfer ribs and bars can be provided in the duct to provide increased heat transfer where necessary.

In an ultrasonic transducer assembly, a conformable ultrasonic transducer has a piezoelectric layer and electrodes able to conform to curved surfaces, and a clamp for pressing the transducer into ultrasonic contact with a curved surface. Conformability is ensured with a thin, porous piezoelectric layer and suitable electrical conductors and insulators. The ultrasonic transducer may operate without further thermal shielding under harsh environments and/or at high temperatures.

Durch einen Zusatz von feinteiligem Glimmer bzw. von Glimmerschuppenpigmenten lassen sich Siedeverzüge bei Destillationen und chemischen Reaktionen auch in technischen Maßstab sehr wirksam vermeiden.
