Title: The Innovative Contributions of Rolf Ryham
Introduction
Rolf Ryham is an accomplished inventor based in Sollentuna, Sweden. He has made significant contributions to the field of chemical engineering, specifically in the treatment of waste liquors. With a total of two patents to his name, Ryham is recognized for his innovative approaches to improving industrial processes.
Latest Patents
Rolf Ryham's most recent inventions focus on advanced methods for the evaporation and deactivation of spent liquor. His first patent, titled "Method for Evaporation of Spent Liquor," introduces a novel process that utilizes heat from a blow condenser. This method involves condensing blow steam from a pulp cooker in a direct condenser that is connected to a hot water accumulator. The spent liquor is indirectly heated and expanded, with the released expansion vapor being harnessed as a heat medium in the subsequent evaporation stage. The apparatus designed for this process includes a heat exchanger, multiple flash tanks, and an evaporation unit, resulting in an efficient system for handling spent liquor.
His second patent, "Method and Apparatus for Deactivating Spent Liquor," addresses the deactivation of calcium-containing sulfate spent liquor through heating. In this innovative system, the spent liquor is heated using direct condensing in a flash steam system. The generated liquor vapors during the expansion of the already deactivated spent liquor are repurposed for heating. The design includes a retention tank and a series of direct condensers and flash tanks, allowing for an optimized counter-current process that enhances efficiency and effectiveness.
