26 Claims

1. A method of providing improved stability and filtration of fluid process stream flow 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 zone, passing the fluid process streams through an entry zone located upstream of the processing zone,

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 material is 2500-4000 times greater than the weight per piece of the processing elements in the processing zone.
