Abstract
A grid of pipes for conducting steam at a pressure greater than a vessels' operating pressure and delivering the steam throughout the grid forms the internals for a tailings solvent recovery unit. The delivery of steam throughout the grid aids in maintaining a relatively low partial pressure throughout the vessel to act as a driver for mass transfer. Conducting the steam at the higher pressure through the pipes in the grid permits a surface of the pipes to be heated to a temperature higher than possible in a conventional vessel, increasing the heat transfer to the feed stream which flows through the grid.
