HEAT EXCHANGER POLYMERIZATION REACTORS FOR MANUFACTURING DRAG REDUCING AGENTS

Temperature control and efficient heat transfer are important to producing high quality polymer drag reducing agents from alpha-olefin and/or other monomers. Many polymerization reactions are exothermic, and controlling or minimizing the exotherm combined with low reaction temperatures yields high molecular weight and, for poly(alpha-olefins), high quality drag reducing agent polymers. It has been found that a shell and tube heat exchanger-type reactor, with the inner tubes hosting the reaction mixture and a coolant circulating through the shell side gives good temperature control. The use of appropriate release agents helps to keep the inner reaction chambers from building up any polymer residue. These reactors can be operated in a continuous filling and harvesting mode to facilitate the continuous production of polymer drag reducing agent and related formulations.

Reformer

Miniaturized reaction apparatus

A stacked plate chemical reactor in which simple plates, each incorporating no surface features other that an opening, are stacked together. When openings in adjacent plates are properly aligned, a fluid pathway is defined between inlet ports for each chemical reactant and an outlet port for a chemical product. In one embodiment of the invention, sixteen simple plates are stacked to provide a reactor incorporating three heat transfer fluid pathways, two reactant fluid pathways, one product fluid pathway, multiple mixing chambers, multiple reaction chambers, two reactant pretreatment heat exchangers, two reaction chamber heat exchangers, and multiple temperature sensor pathways. Precise dimensional control of the reactant fluid pathway height enables stacked laminar flow paths for the reactants to be achieved, allowing efficient and rapid diffusion mixing to occur. Because the simple plates incorporate no features other than openings, fabrication of such plates is easily achieved. Different reactor designs, having additional reactant pathways, more or fewer heat transfer fluid pathways, more or fewer heat exchangers, more or fewer mixing chambers, more of fewer reaction chambers, and more or fewer sensor pathways can readily be achieved by adding or removing plates from the stack, and or by changing the pattern and number of openings in the simple plates that are used. The simple plates can be field in the stack during use of the chemical reactor using pressure exerted on opposite outer simple plates of the stack, or can be permanently joined. A preferred material for the fabrication of the plates is stainless steel, although other materials such as glass, plastic, and other metals can alternatively be used, which are compatible with the selected reactants and the desired product.

Reforming unit and method for converting reagent into reaction products (alternatives)

FIELD: plate- type reforming units. SUBSTANCE: reforming unit is essentially stack of heat-conducting plates with catalytic strips in-between that has inner and outer reagent receivers. Catalytic strip is in direct contact with heat-conducting plates so that its temperature does not actually differ from that of heat-transfer plate; mechanical design of the latter is such that almost isothermal conditions are ensured in plate plane. As an alternative, one or more catalysts may be used and distributed along flow direction in plane of heat-transfer plates. Unit may function as steam reforming or partially oxidizing facility. In case of steam reforming heat energy required for steam reforming is supplied from outside due to radiation and/or heat transfer to heat-conducting plates. Reaction products are carbon oxide, hydrogen, steam, and carbon dioxide. In case of partial oxidation some portion of natural gas is oxidized in the environment of combustion catalyst and reforming catalyst. Reaction products are carbon oxide, hydrogen, steam, and carbon dioxide, Since catalytic strip is in direct thermal contact with heat-conducting plate, excess temperature cannot build up inside stack.

Patent MX232741B

Catalytic reactor

A compact catalytic reactor for Fischer-Tropsch synthesis (50) comprises a reactor module (70) defining a multiplicity of first and second flow channels arranged alternately, for carrying a gas mixture, and a coolant respectively. A removable gas-permeable catalyst structure (82) with a substrate for example of metal foil is provided in each flow channel in which the synthesis reaction is to occur. The reactor module (70) is enclosed within a pressure vessel (90), the pressure within the pressure vessel being arranged to be at a pressure substantially that of the high pressure reacting gas mixture. Consequently all the flow channels within the module are either at the pressure of their surroundings, or are under compression; no parts are under tension. This simplifies the design of the module, and increases the proportion of reactor volume which can be occupied by the catalyst.

Scalable continuous production system

A parallel chemical production system (110) producing a desired product by operating a plurality of reactors (124a-124d) in parallel. The fluidic properties of each of the reactors (124a-124d) is identical to the properties of a test reactor employed to determine conditions for producing the product, to facilitate scaling up production. In one embodiment, the production system (110) is configured such that at least one reactor (124a-124d) is always offline for servicing and use as a backup. If sensors (548a, 548b) detect less than optimal conditions in any reactor (124a-124d), the reactor (124a-124d) is taken offline and serviced while a previously designated backup reactor (124a-124d) is placed online to maintain continuous production. Another aspect involves arranging the reactors (234) in a concentric configuration to facilitate equal fluid distribution.

Electrocoagulation reaction chamber and method

Dielectric rails ( 112 ) support an electrode stack ( 109 ) that is compressed between end pressure plates ( 118 ). The stack is composed of a dielectric spacer ( 46, 103 ) forming a central spacer opening, separating a pair of electrode plates ( 101,102 ) that each have a different configuration of openings. A first electrode plate ( 101 ) of the pair has a central aperture, while the second electrode plate ( 102 ) of the pair has peripheral apertures. A compression device such as a hydraulic cylinder ( 124 ) compresses the stack, sliding the plates and spacers together to form a pressure-tight reaction chamber ( 108 ). When the cylinder is released, any plate or spacer is readily removed from the stack for replacement or maintenance merely by lifting it off the rails. An electric potential can be applied to each electrode plate at a connecting ear ( 116 ), which may be a one of the rail guides ( 116 ).
