Title: Ernst Kriegel: Innovator in Viscous Mixture Separation and Petroleum Recovery
Introduction
Ernst Kriegel is a notable inventor based in Essen, Germany. He has made significant contributions to the fields of chemical engineering and petroleum recovery. With a total of 6 patents to his name, Kriegel has developed innovative methods and apparatuses that enhance the extraction processes of viscous materials.
Latest Patents
One of Kriegel's latest patents is an "Apparatus and method for the separation of a viscous mixture." This invention involves charging a viscous mixture with solvent to form a dispersion before extraction, which improves the extraction efficiency compared to simple solvent extraction. The method allows for the treatment of highly viscous, pasty materials by spraying the mixture into an extraction column after it has been charged with solvent. This process can be optimized by providing favorable temperature and pressure conditions in a separate charging column.
Another significant patent is the "Method for recovering petroleum." This process is designed for extracting petroleum from deposits that have already undergone primary extraction or are unsuitable for it. By introducing a gas in its supercritical state into the deposit, the gas becomes charged with petroleum as it flows through. The charged supercritical gas is then separated into multiple fractions, allowing for efficient petroleum recovery.
Career Highlights
Throughout his career, Ernst Kriegel has worked with prominent companies, including Fried. Krupp Gesellschaft mit beschränkter Haftung and Fried Krupp. His work in these organizations has contributed to advancements in extraction technologies and methodologies.
