ILUDEST DESTILLATIONSANLAGEN GMBH

The instrument has a capacity of 6 litres of solvent mixture with a throughput of up to 1 l / hr (e.g. when recovering Xylene). A microcomputer controller holds up to 100 programs as well as monitoring the distillation process for normal and safe operation. Variable reflux ratios and equilibrium times are possible so that the operator has maximum flexibility to design a program for optimal efficiency. Other capacities are available upon request.

Because of the thermal sensitiveness of products, this separation method is applicable. The medium which is to be distilled is exposed only for a very short time to the heating substances because the film, which is created by the wiper, can evaporate very quickly. The residence time of medium on the heating surface is a matter of seconds, thus essentially less than in a reboiler flask, circulating evaporator etc. Evaporators in borosilicate glass 3.3 are available with heat exchange areas 0.02…0.8 m². Alternative design versions in stainless steel for higher throughputs are available upon request. Please equire.

The sample to be distilled is exposed only for a very short time to the heating substances because the film, created by the wiper, can evaporate very quickly. The residence time of medium on the heating surface is a matter of seconds, thus essentially less than in a reboiler flask, circulating evaporator etc. The evaporated product (operation pressures down to 103 mbar and temperatures up to about 300°C) has to pass a “short path” to the condenser only, which is located in the middle of the evaporator. Evaporators in borosilicate glass 3.3 are available with heat exchange areas 0.02…0.8 m². Evaporators in stainless steel can be heated by a heating jacket to higher temperatures with more heat transfer area for higher throughputs.

The unit for the liquid/liquid extraction operates in a countercurrent flow and is designed as a pulsed column with sieve trays and packing material alternatively. The working principle of this unit is based on the fact, that the two liquid phases are pressed through the holes of each sieve tray or through the packing respectively, forced by the used pulsation, thus one phase will be dispersed into the other. The large contact surface which will be formed by this specific design, makes the product exchange between the two phases highly efficient. During the return travel of the pulsator, the drops previously dispersed are agglomerating into a homogeneous phase. The light phase will be fed into the system at the lower end of the column, while the heavy phase is entering the tower at the upper end. Due to the gravitation, supported by the said pulsation, both phases are passing the column in countercurrent way and are withdrawn at the opposite ends.

For liquidliquidextraction according to the MixerSettlerprinciple, design acc. to Dr. E. Müller (Lurgi). With screw stirrer for intensive mixing of the phases, especially suited for metallic salt extraction. Pumping capacity and residence times are changed by adjusting the stirrer speed. An additional advantage of the unit is the application for extractions during which reactions of considerable density changes occur. Typical applications for this universal apparatus are metal salt extractions mixtures with low surface tension if the dispersed phase coalesces with difficulty if variation in residence time of the phases occur in the extraction stages if reactions are expected during the extraction process if considerable changes in density are expected as a result of extraction
