摘要: A vertical electrostatic coalescer comprises a first and second electrode surface and a horizontally disposed foraminous surface. The first electrode surface and horizontally disposed foraminous surface are at ground potential. The first and second electrode surfaces share the same planar orientation relative to the central longitudinal axis of the vessel. The unique arrangement of the vessel and opposing pairs of first and second electrode surfaces provides for a substantially uniform voltage field around a perimeter of the vessel and an effective voltage field for coalescence within a center of the vessel. A circular-shaped distributor pipe or a distributor housing serves to absorb momentum of the incoming emulsion stream and distribute the stream into an interior of the vessel.

摘要: A pet perch comprising of a rectangular wire frame and wire wall brace with brace clips that firmly attaches the frame to the wall brace. The assembly can be attached to window sills (single hung and double hung design) using sill clips or to windows without sills (casement design) using sill clips eliminating the necessity for attachment by screws, hook and loop fasteners and suction cups. The assembly can be moved from window to window since the sill clips are easily movable

摘要: Disclosed herein is a process for monetization of natural gas by producing fuel grade dimethyl ether (DME). The process includes three reactive stages with the first reactive stage being the conversion of natural gas into syngas, the second reactive stage being the conversion of syngas into crude methanol and the third reactive stage being the production of fuel grade dimethyl ether. The management and optimization of the water and steam circuits is important to maintain net overall system efficiency and mitigation of any liquid effluents.

摘要: Disclosed herein is a process for the production of fuel grade DME from carbonaceous fuels, including a pressurized multi-stage progressively expanding fluidized bed gasifier and an oxyblown autothermal reformer to produce a synthesis gas (syngas) with desirable hydrogen to carbon monoxide molar ratio, which then undergoes gas-phase DME one-step direct synthesis in a fluid pluralized bed reactor over an attrition resistant bifunctional catalyst. The crude DME thus obtained is purified in a two column distillation unit to produce a fuel grade DME having a purity greater than 99.98 mole %.

摘要: An improved double tube reactor having a plurality of inner and outer tube assemblies each of the assemblies having a reaction annular volume between the inner tube and outer tube and a closed center plug within the inner tube forming an annular thermal exchange volume between the center plug and the inner tube to obtain desired temperature control of exothermic and endothermic catalytic chemical reactions. In one embodiment of the invention, the improved double tube reactor is used in a process for production of high purity methanol from process gas produced by steam reforming hydrocarbon feedstocks in a tube type reformer followed by removing substantially all CO.sub.2 and H.sub.2 O from the process gas, adjusting the H.sub.2 /CO molar ratio to about 2 when necessary, and feeding the adjusted process gas to a methanol synthesis reactor contacting a methanol forming catalyst not requiring CO.sub.2 activation at about 200.degree. to about 300.degree. C. to produce product gas comprising methanol, and recovering liquid methanol having purity greater than about 99.85% pure by cooling the product gas to a temperature below the boiling point of methanol and separating the liquid methanol from gaseous components of the product gas. In a preferred embodiment, process gas of H.sub.2 /CO molar ratio of about 2.0 to about 2.5 is passed through an annular thermal exchange volume between a center plug and an inner tube followed by passing the gas in contact with a catalyst in a catalyst bed between the inner tube and an outer tube of a double tube reactor assembly promoting the direct reaction of H.sub.2 and CO to product methanol.

摘要: This invention discloses a method for making a dimethylether (DME) product from a synthesis gas (syngas) in the presence of a catalyst in a fluid pluralized bed reactor operating in the gas phase. The reactions generate a significant amount of heat and the heat management is balanced between supplying quench recycle syngas to the pluralized sections along the reactor and also by controlling the preheat temperature of the reactant streams. Gas phase fluidization of the catalyst is controlled so that the pluralized reactive zones are maintained in a backmix configuration.
