Title: Jussi K Rastas: Innovator in Metal Recovery and Environmental Solutions

Introduction

Jussi K Rastas is a notable inventor based in Pori, Finland. He has made significant contributions to the fields of environmental technology and metal recovery, holding a total of 12 patents. His innovative approaches address critical issues such as mercury removal and the recovery of valuable metals from waste materials.

Latest Patents

One of Rastas's latest patents is a process and apparatus for the removal of mercury from sulfur. This invention involves cooling and scrubbing hot gases from smelting or roasting plants using a concentrated sulfuric acid mist. The process effectively sulfatizes mercury, allowing for its separation from the gases. The cooling is achieved by vaporizing water or dilute sulfuric acid solution, which lowers the gas temperature below the dew point, producing a sulfuric acid mist that washes the mercury. The gases are then directed to the sulfuric acid plant after separation from the mist.

Another significant patent by Rastas is a process for the recovery of valuable metals from spent crude-oil sulfur-extraction catalyst waste. This innovative method allows for the separation of valuable metals from aluminum in a single stage. By treating the waste at elevated temperature and pressure with a sulfate solution, the waste dissolves while aluminum precipitates as alunite, which can then be separated from the solution containing other valuable metals.

Career Highlights

Throughout his career, Jussi K Rastas has worked with prominent companies such as Outokumpu Oy and Outokumpu Oy. His experience in these organizations has contributed to his expertise in developing innovative solutions for environmental challenges and metal recovery.

Collaborations

Rastas has collaborated with notable professionals in his field, including Sigmund P Fugleberg and Heikki A Tiitinen. These collaborations have further enhanced his research and development efforts, leading to impactful inventions.

Conclusion
