Title: Heikki Tuovinen: Innovator in Waste Treatment Technologies
Introduction
Heikki Tuovinen is a notable inventor based in Ulvila, Finland. He has made significant contributions to the field of waste treatment technologies, particularly in the recycling of process waste containing sulfur and phosphorus. With a total of three patents to his name, Tuovinen's work has the potential to impact both environmental sustainability and industrial efficiency.
Latest Patents
One of Tuovinen's latest patents is a regeneration method for process waste containing sulfur and phosphorus. This innovative method treats process waste obtained from the synthesis of thiophene or its derivatives. The process produces phosphorus pentasulfide of sufficiently high purity for recycling in the synthesis process. Additionally, it generates a residue material that can be utilized as a raw material for fertilizers. The treatment method involves vacuum evaporation in a combination heating/evaporation reactor at temperatures between 500°C and 700°C, under a partial vacuum of 0.01-0.2 atm. To enhance the yield of evaporating phosphorus pentasulfide, sulfur is added to the process waste. The resulting phosphorus pentasulfide is condensed and can be pulverized if desired. The usable, phosphorus- and potassium-containing evaporation residue is then removed from the reactor and cooled for further use.
