    摘要： Process and apparatus for fluidized bed mixing of fluids and gases in which the fluid is injected with a high angular velocity through a relatively narrow, preferably single, orifice (3). The angular velocity may be imparted by injecting the fluid at high velocity tangentially at the periphery of the squate chamber (4) so that angular momentum is gained as it spirals inwards towards orifice (3). Optionally, an open-topped hopper (5) for solids is suspended above orifice (3). The lower end of the hopper (5) terminates in a second orifice (7) located vertically above orifice (3). The solid particles are thereby swept radially outwards towards the wall of the chamber (1) in co-current admixture with the fluid.

    摘要： In a process for producing 1,2-dichloroethane or ethylene dichloride ("EDC") in a high temperature direct chlorination ("HTDC") reactor in which ethylene is reacted with wet chlorine having a water content more than 100 ppm but no more than 1% by wt of the chlorine, the water leaves the reactor with the EDC product draw-off, either in the vapor overhead (if the HTDC is a boiling reactor), or, as a liquid sidestream (if the HTDC is a non-boiling reactor). In a subsequent step, the EDC draw-off is distilled in a product distillation column in which the water leaves in the overhead which is condensed to remove condensables in a first stage, and vent a non-condensable vent streams. The vent stream is corrosive due to the presence of minor amounts of chlorine, HCl and water, along with oxygen which is injected into the HTDC to improve selectivity of the reaction. The vent gases from the first stage are further cooled to a temperature in the range from about -30.degree. C. to about 0.degree. C. to condense condensables and freeze water without plugging the liquid lines. Plugging is avoided provided the vent stream contains less than 1.5% by wt of water, based on the weight of the vent stream. The essentially moisture-free non-condensables remaining are relatively non-corrosive and may be recycled to an oxychlorination reactor, also for the production of EDC, without unduly sacrificing the vent compressor and other carbon steel equipment in the recycle line.

    摘要： Oxidized molten chloride salts are employed for chlorinating and/or oxychlorinating a feed in a first reactor and then passed by gravity to a second reactor situated below the first reactor and operated at a pressure higher than the first reactor wherein the molten salt is oxidized. The oxidized salt is returned to the first reactor. Vinyl chloride or chloromethanes can be produced by the process.
