Abstract
A dual-wall pressure balanced vessel for processing high viscosity slurries at high temperatures and pressures having an outer pressure vessel and an inner vessel with an annular space between the vessels pressurized at a pressure slightly less than or equivalent to the pressure within the inner vessel.
Claims8
A dual-shell pressure balanced vessel, comprising:
- an outer vessel completely enveloping a continuous flow inner vessel with an annular space therebetween, said inner vessel having an inlet and an outlet penetrating through the annular space and the outer vessel, said continues flow inner vessel containing a fluid pressurized to a first pressure, said annular space having a fluid pressurized to a second pressure, and
- a means for equalizing said first and second pressures wherein the second pressure in the annular space results from the first pressure in the continuous flow inner vessel while preventing mixing of said first and second fluids.
