Abstract

Claims (6)

1. A trickle bed process vessel for treatment of a reactant-lean, product-rich liquid stream, comprising:

an exchange layer comprising a plurality of collector media and a plurality of releaser media, wherein the exchange layer is capable of facilitating diffusion of one or more reactants from a gas phase into a reactant-lean, product-rich liquid phase within the exchange layer to form a reactant-rich, product-lean liquid phase; and

a treatment layer downstream of the exchange layer comprising a bed of porous solid elements, the porous solid elements comprising at least one of catalysts, sorbents and reactants and capable of performing a treating process to remove an undesired species from the liquid phase,

wherein the collector media comprise porous solid materials capable of collecting the reactant-lean liquid phase within the collector media, and wherein the releaser media comprise solid materials having a thin film formed on an outer surface thereof that is capable of facilitating contact and diffusion between the reactant-lean, product-rich liquid phase and the gas phase, and wherein the thin film is formed on the releaser media during processing as a result of liquid released from the collected liquid phase, and wherein the size of the releaser media is no more than one-fourth the size of the collector media.

2. The process vessel of claim 1 , wherein the releaser media comprise at least one of catalysts, sorbents and reactants.

3. The process vessel of claim 1 , wherein the undesired species comprises at least one of sulfur, nitrogen, oxygen, aromatics, olefins, nickel, vanadium, iron, silicon or arsenic, and wherein the reactant-rich, product-lean liquid phase comprises at least one of naphtha, gasoline, kerosene, jet, diesel, gas oils, vegetable oils, animal tallow, and liquid water, and wherein the reactant diffused from the gas stream into the reactant-lean, product-rich liquid stream comprises at least one of methane, butane, propane, butalene, propylene, hydrogen, ammonia, hydrogen sulfide, carbon dioxide, carbon monoxide, sulfur oxides, nitrogen oxides, water gas, oxygen, and nitrogen.
