  • Method for the cooling of hot gaseous solids suspensions of titanium dioxide
    Patent number: 4633935
    Abstract: The invention concerns a device for the cooling of hot gaseous solids suspensions, particularly for the cooling of hot gaseous TiO.sub.2 suspensions resulting from the production of titanium dioxide by vapor phase oxidation of titanium tetrachloride. The device consists of a number of coaxially connected constructional units, each of which consists of three jacketed tubes, i.e., tubes 1, 2 and 3, which are coaxially connected in such a way that tube 1 conically tapers toward tube 2 and that tube 3 is larger in diameter than tube 2. Heat transfer is twice as high in the device of the invention as in a comparable conventional cooling tube of uniform inner diameter; moreover, the demand of scrub solids needed to prevent the formation of deposits on its walls is reduced to one third of the quantity needed in a conventional cooling tube.

  • On line scrubbing system for plate and frame heat exchangers
    Patent number: 4630672
    Abstract: Air under pressure is injected into a contaminated fluid flowing into a plate and frame heat exchanger.

  • Heat exchange apparatus for high temperature LPCVD equipment
    Patent number: 4630669
    Abstract: A heat exchanger apparatus having two sleeves which fit together to seal a sinuous heat exchange fluid channel between them where the channel is open along its length prior to assembly. The sleeves may be made removable to permit easy cleaning of the heat exchange fluid channel. The heat exchange fluid channel may thus be directly cleaned along its entire length in contrast to conventional heat exchangers employing tubes, where the tube interior can be accessed only from the ends. In one embodiment, the channel has a rectangular cross-section to enhance the heat exchange capability of the apparatus.
