Latest Patents

Shimada's latest patents include a process for the distillation of styrenes. This invention provides a method that can be stably operated without losing energy-saving effects. It involves leading a part or all of the low boiling point component vapor from the top to a compressor, which is then used as a heat source for a reboiler. The low boiling point components condensed in the reboiler or a mixture of the condensate and a part of the uncondensed vapor is returned to a recycling line of a distillation column. Another significant patent is a tube expander designed for fixing tubes to a tube plate of a boiler or a multitubular heat exchanger. This expander incorporates an elastic expanding medium that is inserted into a tube to expand radially against the wall of a tube-receiving bore of the tube plate. It includes a pressurizing rod, a back-up ring, and seal rings made of a hard elastic material.
