摘要： The present invention relates to an apparatus for treating waste containing mercury and a method for recovering high purity elemental mercury using the apparatus. More specifically, the present invention may provide a method that can more economically and stably recover high purity elemental mercury from waste containing mercury using an apparatus for recovering mercury from waste containing mercury, the apparatus comprising: a thermal desorption unit; a dust control unit; and a condensation and recovery unit, which are connected in series. The present invention has an advantage in that, compared to a conventional simple heat treatment-condensation method, a high recovery rate of mercury is achieved and high purity mercury can be obtained.

摘要： Selective recovery of C2 to C4 hydrocarbons is achieved through the use of a converging-diverging nozzle, or de Laval nozzle. The vapor stream comprising C2 to C4 hydrocarbons is fed into an inlet of a de Laval nozzle having a throat. The vapor stream may have an initial temperature of between 0° C. and 100° C., and an initial pressure of between 200 psig and 500 psig. In the de Laval nozzle, the vapor stream expands after passing through the throat of the de Laval nozzle, producing a vapor stream having reduced temperature and pressure. Then, C2 to C4 hydrocarbons condense from the reduced-temperature vapor stream as liquid droplets, which may be recovered. Fractionation of C2 to C4 hydrocarbons by means of a de Laval nozzle is possible; the technique allows selective recovery of a stream enriched in propene from a mixture of propane and propene.

摘要： The invention relates to a process for the production of urea ammonium nitrate, a system and a method of modifying a plant. The process comprises subjecting ammonia-containing off-gas resulting from the production of ammonium nitrate (AN off-gas) to condensation under acidic conditions so as to form an acidic condensate, and using at least part of the acidic condensate as an acidic scrubbing liquid in a finishing treatment section having a gas inlet in fluid communication with a gas outlet of a finishing section of a urea production unit, wherein the finishing section is adapted to solidify urea liquid, and wherein said finishing treatment section is adapted to subject ammonia-containing off-gas of the finishing section to treatment with an acidic scrubbing liquid.

摘要： A process to prevent fouling using a desublimating heat exchanger is disclosed. An outlet stream from the desublimating heat exchanger may be split into a plurality of parallel streams. The parallel streams may be sent through other devices for performing a unit operation, and the devices for performing a unit operation may change the temperature of at least one of the parallel streams. Parallel streams of differing temperature may emerge from the devices for performing a unit operation. The parallel streams of differing temperature may be sent to a mixing chamber. A mixed stream of uniform temperature may emerge from the mixing chamber, and the mixed stream may be recycled back to the desublimating heat exchanger. The mixing chamber may be separate from the desublimating heat exchanger, or the parallel streams of differing temperature may be mixed in the desublimating heat exchanger.

摘要： A distillation probe includes a conduit having a central axis. In addition, the distillation probe includes a baffle assembly disposed in the conduit. The baffle assembly includes a plurality of axially-spaced baffles positioned one-above-the-other in a stack within the conduit. Further, the distillation probe includes a first helical cooling coil wrapped around the conduit. Moreover, the distillation probe includes a thermally conductive layer disposed about the conduit and encapsulating the first helical cooling coil. The thermally conductive layer is configured to transfer thermal energy between the first helical cooling coil and the conduit.
