Abstract

An evaporation system for aqueous radioactive waste uses standard 30 and 55 gallon drums. Waste solutions form cascading water sprays as they pass over a number of trays arranged in a vertical stack within a drum. Hot dry air is circulated radially of the drum through the water sprays thereby removing water vapor. The system is encased in concrete to prevent exposure to radioactivity. The use of standard 30 and 55 gallon drums permits an inexpensive compact modular design that is readily disposable, thus eliminating maintenance and radiation build-up problems encountered with conventional evaporation systems.

Tar sands conditioning drum. [design of muller-type drum for initial conditioning of mined tar sands by the hot water method]

Patent Raymond, B.W.; Riva, D.A.; Stuchberry, F.C.

A rotating drum type muller is described for initial conditioning of mined tar sands by the hot water method for separation of bitumen from the sands. Ablation of mined tar sand lumps into pulp is effected through the addition of hot water, steam, and caustic. This conditioning drum consists of a horizontally disposed cylindrical drum of a length to diameter ratio of about 1:1 or less, rotatable around its longitudinal axis. It has axial openings at its inlet end for introduction of mined tar sand lumps, water, and caustic and at its outlet end for rejection of oversize particles. Themore »« less
Conditioning drum for a tar sands hot water extraction process

Patent Tchernyak, S. S.

The thermodynamic efficiency of a tar sands conditioning drum is improved by continuously and simultaneously discharging steam from all the nozzles of an array of a few relatively large nozzles distributed circumferentially around the inner drum periphery rather than selectively sparging the steam only from those nozzles beneath the tar sands pulp surface. As a result, the drum shell and components above the pump are heated and thus heat the pulp by radiation and, after entering the pulp, by convection as well as by sparging. Hot water droplets formed continuously in the steam cloud rain onto the pulp surface tomore »« less
