Kelvion Mini Desublimator – Pluto Desublimation “by Kelvion”: smart, sustainable, customi

GEA Heat Exchangers has changed: another new standalone company has been created out of the former Heat Exchanger Division of the GEA Group AG. The name Kelvion is new, but we continue as global experts in heat exchange. As always, we remain committed to earning your trust. You'll still recognize us. We continue to develop our products, manufacture them with precision and distribute globally. We con- tinue to offer one of the world's largest heat exchanger product portfolios: Plate heat exchangers, shell & tube heat exchangers, finned tube heat exchangers, modular cooling towers and...

A reliable partner Kelvion views itself as a value-added partner throughout the complete lifecycle of a product or project. Maximization of customer satisfaction is achieved by closely observing and optimising all relative steps − planning, installation, start-up, operating costs, maintenance and upgrades. Kelvion has one of the most comprehensive portfolios, if not the most comprehensive, of heat exchangers in the world. Within this segment desublimators are developed and manufactured in the Shell & Tube Competence Center. The desublimation specialists: Comprehensive engineering and...

Imitating nature The formation of hoarfrost is an example of desublimation. Water contained in the air is directly deposited on cold surfaces directly in its solid (crystalline) phase. This natural „experimental design“ was reproduced by Kelvion engineers in a desublimator for substance separation – and immortalized in metal as it were. Desublimation is the direct phase change of a substance from Solid phase Liquid phase its gaseous to its solid (crystalline) phase. This physical phenomenon is known from nature: In winter air-bound moisture is deposited as hoarfrost. The log p/T diagram...

Desublimation “by Kelvion”: smart, sustainable, customized In the Pluto unit the gas mixture comes into contact with cooled lamellas. Here that part of the gas mixture to be separated desublimates either around or below its triple point and adheres to the cold surface in crystalline form. The Pluto unit is split into Substances that can be separated by desublimation in Pluto: several sectors to prevent too much of the substance being deposited close to the gas inlet. A range of lamella designs are available for optimum utilization of the heat exchanger surface – and the sectors are adapted...

Breathe in the air Even close to storage tanks we can still breathe easily by using desublimators for cleaning contaminated waste gas. Emission protection A typical application for the Pluto unit is the cleaning of polluted waste gas streams. Fuel tanks or storage tanks in the chemical industry containing combustible or potentially explosive substances are regularly charged with inert gases. These inert High unit reliability: No direct weld seams between gas and cooling/heating side gases include nitrogen or noble gases, for example. Gastight housing (welded, not Over the course of time the...

Recovery of valuable (raw) materials In the chemical and pharmaceutical industries it is not unusual that valuable raw materials High process reliability: have to be charged to the production process, but which are not intended to be present in the end product after the desired reaction. An example of this is iodine, which occurs less often than the other halogens and is therefore more expensive, and which is also classified Defined loading times as a hazardous substance. Iodine contained in gaseous substance streams desublimates Long loading times possible even at room temperature. Using...

Maintaining values Whether our customers recover unneeded raw materials from the end product or increase the operational reliability of their facilities – the use of desublimators maintains values and safeguards investments. Protection of downstream components A classic problem in process engineering is that the vacuum generator draws in a substance mix that is already contaminated and this can lead to blockages. Kelvion has developed a skid-mounted vacuum station e.g. for the PA process. Here two Pluto units are used to clean Pluto application fields: Product recovery in chemical and...

Prior to delivery, the Pluto is subject to pressure testing Pressure test passed - this Pluto is ready for shipping. with water according to the standards. Manufacturing and quality Kelvion has been developing and manufacturing desublimators since 1954. And the Pluto unit has been a popular model in our product range since 1982. Our engineers base their expertise not only on thermodynamics and heat engineering, but also integrate numerous customer-specific process-engineering applications. And our customers can make use of and benefit from this unique know-how. With their intimate knowledge...

In good hands during the entire service life At Kelvion, plant operators benefit from both manufacturing know-how and application knowledge. This is why these apparatus are optimally designed, installed and serviced. Full service from the start Kelvion is your reliable partner and direct contact around the clock. Even at the International certification: preliminary plant design stage our consulting experts assist in tailoring manufacturing aspects with our in-house maintenance experts. However, if used for their intended purpose our desublimators are practically maintenance-free, besides...
