Since the invention of the Desublimator in 1954 we have delivered about 1500 Desublimators worldwide. We have continuously developed the mechanical as well as the process design of the Desublimators. In particular, we have adapted the special designed fin tube system composed of rectangular fins to the newest requirement of the PA process, mainly to the increasing feedstock loading of the air.
Desublimation is a thermodynamic method for separating product from a gas stream and is an alternative to adsorption and absorption. The separation is achieved by cooling and heating in batch-operation. It is used, for example, in chemical and pharmaceutical processes, to secure vacuum pumps or for tank venting. The separated component can be an invaluable raw material or may be hazardous for the environment. In the Desublimator unit the gas mixture comes into contact with cooled lammaellas/fins. 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 Desublimator unit is split into several sections to achieve an optimum distribution of the product inside the Desublimator. This special design feature ensures the highest separation efficiencies and longest loading times.
