摘要： The present invention relates to a method of pretreating, by acidification and chelation, of pulp to be bleached with peroxide. Especially, the invention relates to intensifying, and at the same time simplifying the pretreatment required by peroxide bleaching. It is characteristic of the invention to introduce pulp into an acid tower (14, 112) where the pressure is 0 to 20 bar, preferably 1 to 10 bar, and the temperature 75 to 130 °C, preferably 80 to 110 °C, to treat the pulp in acid tower (14, 112) at a pH of 2 to 6, preferably 3 to 4, for 20 to 240 minutes, for decreasing the kappa number by 1-9, preferably 2-6 kappa units, to transfer the pulp from acid tower (14, 112) to a tower (24) of a second treatment stage, to treat the pulp with either a complexing agent at a pH of 4 to 9, preferably 5 to 6, or with an oxidizing chemical such as chlorine dioxide, Caro's acid, peracids or equivalent, and to wash and/or press the pulp.

摘要： A lower header (10) on the side of an inlet for a low-temperature liquid and an upper header (16) on the side of an outlet therefor are connected together via a plurality of external heat transfer pipes (22). In the interior of each external heat transfer pipe (22), an internal heat transfer pipe (24) is provided which extends from the inlet side end of the external heat transfer pipe (22) to a portion thereof which is short of the outlet side end of the mentioned pipe. Between the outer surface of the internal heat transfer pipe (24) and the inner surface of the external heat transfer pipe (22), a low-temperature liquid circulating passage (23) communicating with the interior of the lower header (10) is formed.

摘要： A heat exchanger comprised of a plurality of plates (14, 15) bonded face-to-face with one another. Either or both faces of the plates (14, 15) have upstanding fins (16, 17, 40, 41, 53, 54, 55) which define passages for fluid flow. Each plate (14, 15) has a distribution zone (12) and a main heat exchange zone (11). The fins in the distribution zone (12) include fins (17, 40, 41, 53, 54, 55) which are aligned differently from adjacent fins along the direction (51, 52) of fluid flow.

摘要： A heat exchanger element comprises an outer tube (11), an inner tube (12) within the outer tube and a first fluid flow path for a first heat exchange fluid formed between the inner and outer tubes. A second heat exchange fluid is in heat transfer relation to the outer surface of the outer tube and/or the inner surface of the inner tube. A sleeve (13) is provided within the first fluid flow path between the inner and outer tubes. The sleeve defines an outer interface (16) with the inner surface of the outer tube and an inner interface (14) with the outer surface of the inner tube. Generally longitudinal grooves (16, 17) are provided at each interface to provide together the first fluid flow path.

摘要： A novel chemical reactor; one particularly useful for the production of polymers, especially elastomers such as butyl rubber. The reactor (10) contains (1) a two-tube pass system, constituted of an inner or center tube bundle (20) through which a mixture or slurry of polymerizable monomers and catalyst is passed in one direction, and recycled via an outer tube bundle (30) in the opposite direction in essentially even flow distribution (2), while the tubes of the center and outer tubular bundles are maintained within a jacketed section, or sections of the reactor into which a coolant, or refrigerant, is injected and vaporized to remove the heat of reaction. The coolant, or refrigerant, in heat exchange relationship with the tubes removes the exothermic heats of reaction from the polymerization mixture, and maintains the polymerization mixture at uniformly low temperature. An even flow circulation of the slurry which aids in maintaining uniform low temperature, is provided by the use of (3) a diffuser (60) and (4) mixed flow pumping system (40), with its impeller (43), by virtue of which an adequate pressure head of even pressure profile is developed across the entry sides of the center tubes (20) to maintain the even flow distribution within the two-tube pass system at high circulation rate. There is no vortex whirl at the exit of the impeller-diffuser assembly, and no cavitation bubbles as commonly associated with one-tube pass systems, which employ a central draft tube and axial flow pump. Improved mixing, high hydraulic efficiency, and higher production rates with low polymer fouling, are achieved.
