Latest Patents

Donaldson's latest patents include the "Dual reactor process and apparatus for polymerizing ethylene." This invention involves a dual reactor system where two reactors are connected in series with a heat exchanger, or intercooler, positioned between them. The reaction stream from the first reactor, which operates at elevated pressure and temperature, is passed through the heat exchanger to cool the stream. After cooling, the pressure of the reaction stream is reduced through a pressure let-down valve before it is introduced into the second reactor for further polymerization. Notably, both reactors can be of the autoclave type, although one may also be of the tubular variety.
