Abstract: Emulsion polymers, formed by reacting a monomer phase with a water phase, are generated in a tubular reactor having a controlled loop section (10) to give a partially developed product, such as one having 5-20% unreacted monomer, and a controlled plug section (11), which is preferably larger than the loop section by a factor of at least two, to give a fully developed product. Means (19, 17) exist to cool both loop and plug sections but preferably to keep the plug section at a higher temperature, which temperature can be zoned. Supplementary reactants may be introduced into the plug section. One such reactant may be a monomer to encase particle cores formed in the loop section with shells. An expansion agent may be included in the reactants which is dormant in the loop section but active in a higher temperature plug section.

Abstract: A tubular reactor for use in polymerisation reactions is described, having a design pressure PR of 40-65 barg, at least a portion of which is oriented vertically and at least part of which vertical portion is surrounded by a concentric jacket for the passage of cooling fluid, wherein the design pressure in barg of the jacket PJ is less than 0.0018.PR225. Another aspect of the invention concerns a tubular reactor for use in polymerisation reactions having a design pressure PR of 40-65 barg, at least a portion of which is oriented vertically and at least part of which vertical portion is surrounded by a concentric jacket for the passage of cooling fluid, wherein the actual thickness of the reactor wall is either no more than 2mm greater and/or no more than 10% greater than the minimum wall thickness required to withstand the design pressure PR as calculated according to the ASME Boiler and Pressure Vessel code.

Abstract: A method and apparatus for safely producing hydrogen peroxide by injecting dispersed minute bubbles of hydrogen (28) and oxygen (34) into a rapidly flowing liquid medium (24). The minute bubbles are surrounded by the liquid medium of sufficient volume for preventing an explosive reaction between the hydrogen and oxygen. The liquid medium is formed of an acidic aqueous solution and a Group VIII metal catalyst (14). Hydrogen (28) is sparged into the flowing medium (24) for dissolution of the hydrogen in the medium. Oxygen bubbles (34) are reacted with the dissolved hydrogen for producing hydrogen peroxide (72). Preferably, the liquid medium has a velocity of at least 10 feet per second for providing a bubbly flow regime in the reactor. Water (12) and catalyst (14) are added to tank (16). Preferably, an amount of hydrogen peroxide stabilizer is added to tank (16). The method and apparatus provide for the safe production of hydrogen peroxide with low manufacturing costs.

Abstract: Un fluide s'écoulant continuellement est traité en l'amenant au sommet d'une colonne hydraulique à tirage descendant (17) dont la hauteur est telle que la pression au fond de la colonne est approximativement égale à la pression nécessaire pour créer des conditions d'eau surcritiques. Le fluide est conduit vers le fond de la colonne (17) et reçu dans une chambre de réaction (21) dans laquelle on fait recirculer la majorité du fluide autour d'une plaque de déviation annulaire (24). Le matériau dans la chambre de réaction (21) est chauffé jusqu'à atteindre une température supérieure à la température nécessaire pour créer des conditions d'eau surcritiques par une réaction indépendante ayant lieu dans une chambre de chauffage (32). Le résultat est que le fluide est soumis à des réactions chimiques dans une plage de température et de pression surcritique et que son poids volumique est inférieur à celui du fluide non traité. Le matériau que l'on n'a pas fait recirculer dans la chambre (21) est amené vers l'une des deux colonnes à tirage ascendant (30, 31), à savoir une colonne de départ (30) utilisée pour rechauffer le matériau dans la colonne de tirage desçandant (17) pendant le début du procédé et une seconde colonne (31) isolée de la colonne à tirage descendant (17) de manière à ne pas lui transmettre de chaleur pendant le déroulement normal du procédé. La température du fluide dans la colonne à tirage descendant (17) est ainsi régulée pour empêcher la décomposition du matériau jusqu'à ce que le fluide entre dans la chambre de réaction (21), moment où il est brusquement amené à la température d'eau surcritique.

Abstract: In forming an electrophoretic gel, various defects can be induced by the shrinkage that generally accompanies polymerization. These defects can include pulling away from a vessel wall or voids or bubbles forming within the gel itself. Prior to polymerization, a monomer can be compressed to a density at least equal to that of the expected density of the final gel, which then is substantially free of such shrinkage defects. The disclosed method is readily generalizable to other situations to produce polymers substantially free of defects due to shrinkage.
