摘要: An ionic liquid reactor unit and a process for controlling heat generation from an ionic liquid reactor unit. The ionic liquid reactor unit may include an external heat exchanger. The effluent from the reactor is separated in a separation zone allowing the hydrocarbon phase to transfer heat to a cooling fluid. The heat exchanger may be a tube-in-shell, a spiral plate heat exchanger, a hair pin heat exchanger. The heat exchanger accommodates the separation of the ionic liquid from the hydrocarbon phase, and may allow for the ion liquid to be drained.

摘要: A polymerization autoclave for the suspension polymerization of vinyl compounds in the aqueous phase having a volume of from 50 to 200 m.sup.3, an impeller agitator driven from below at the bottom of the autoclave and two cylindrical displacement bodies acting as flow interrupters, secured downwardly from the autoclave dome, where the autoclave has a height-to-diameter ratio of from 2.4 to 3 with a critically dimensioned agitator and critically dimensioned flow interrupter fittings. By the use of this invention in the case large-scale autoclaves, the heat of polymerization can be removed merely by wall-cooling. The autoclave according to the invention are very economical, as shown by, for example, a spatial capacity of 0.3 to 0.4 metric tons of polyvinyl chloride per m.sup.3 autoclave volume.

摘要: In the thermochemical water splitting process by Cu—Cl cycle, oxygen gas is produced by a thermolysis process in a three-phase reactor. IN accordance with the teachings herein, a technique is provided to achieve the high challenging thermal requirements of the thermolysis reactor, whereby an optimized heat transfer configuration is used. The technique involves using some of the pre-heated stoichiometric oxygen gas produced from the thermolysis reaction, to transfer heat directly to the slurry of molten CuCl and solid Cu2OCl2 inside the thermolysis reactor. Experiments were performed to examine the volumetric heat transfer coefficient for the direct contact heat transfer between the gas and the slurry. It was found that the thermal scale up analysis of the thermolysis reactor with direct contact heat transfer, is based on the amount of heat carried by the oxygen gas rather than the amount of heat transferred by direct contact heat transfer.

摘要: Process for performing an endothermic reaction in a reactor containing catalyst tubes, the catalyst tubes containing a catalyst promoting the endothermic reaction, the process comprising the steps of, a. contacting the catalyst contained in the catalyst tubes with a feed flow passing through the channels from an entrance end to an exit end, b. contacting an outer surface of the catalyst tubes with a flow of a heating medium having an initial heating temperature and flowing co-currently with the flow of feeds to heat the surface by convection, c. mixing at least part of the heating medium after having been contacted with the catalyst tubes with a flow of fresh heating medium having a start temperature higher than the initial heating temperature to form the co-current heating medium having the initial heating temperature and reactor for carrying out the process.
