Title: Gunter Roller: Innovator in Evaporation Technology
Introduction
Gunter Roller is a notable inventor based in Bad Homburg, Germany. He has made significant contributions to the field of evaporation technology, holding 2 patents that address critical challenges in industrial processes.
Latest Patents
One of Gunter Roller's latest patents is a method of removing encrustations in evaporation plants. This innovative solution involves passing a solution through multiple evaporation stages, where it is circulated between a heat exchanger and an evaporating vessel. Steam is withdrawn from the evaporating vessel, and to remove crusts, the evaporation is temporarily halted. A cleaning suspension containing at least 3 wt % granular solids is then circulated, utilizing the abrasive properties of the solids to effectively eliminate the crusts. Additionally, the solution is circulated through the evaporation stage, where the heat exchanger is heated, allowing the cleaning solution to evaporate sufficiently for solids to crystallize and form a cleaning suspension.
Another significant patent by Roller is a process for preparing low iron ammonium alum. In this process, an aqueous ammonium alum solution containing Fe³⁺ ions and a pH not exceeding 5 is treated to convert at least half of the Fe³⁺ ions to Fe²⁺ ions. The solution is then cooled, leading to the crystallization of ammonium alum, while the Fe²⁺ ions remain in the liquid phase.
