Abstract
Process vessels can contain one or more entry zones containing stability-improving materials. The entry zones address bed movement and filtration problems. The stability-improving material can be positioned above a treating zone or above a processing bed within the vessel. Entry Zones are intended to improve the stability of downstream operations.
Claims27
A method of providing improved stability and filtration of stream flow for fluid process streams in a process vessel comprising:
- passing the fluid process streams through a processing zone within the process vessel, the processing zone containing one or more beds of processing elements;
- and
- prior to passing the fluid process streams through the processing bed, passing the fluid process streams through an entry zone located upstream of the processing bed,
- wherein the entry zone contains a bed of stability-improving materials having a porosity in the range from 67% to 87%, a density in the range from 30-60 lbs/ft3, and a weight per piece of 12-300 grams,
- and wherein the stability-improving materials have internal voids capable of filtering particles from the fluid process stream flow,
- and wherein the weight per piece of the stability-improving materials is 2-25 times greater than the weight per piece of the processing elements in the processing zone.
3 more elements
A process vessel comprising:
- a processing zone containing one or more beds of processing elements;
- and
- an entry zone located upstream of the processing bed, the entry zone comprising a bed of stability-improving materials having a porosity in the range from 67% to 87%, a density in the range from 30-60 lbs/ft3, a weight per piece of 25-200 grams, and an internal void capable of capturing undesired species from a fluid process stream flow passing therethrough, wherein the weight per piece of the stability-improving materials is 2-25 times greater than the weight per piece of the processing elements in the processing zone.
