Abstract
Disclosed is a flow bypass device, a reactor system containing the flow bypass device; a method for operating a fixed bed of solid particles in which gas is re-routed to an interior of the fixed bed, for example, the flow bypass device is used to bypass a portion of the solid particles; and a method for loading solid particles and a flow bypass device into a vessel. The methods and systems can use a single flow bypass device or multiple flow bypass devices that are stacked on top of one another.
Claims19
A method for operating a vessel containing a fixed bed of solid particles, comprising flowing a gas through a first flow bypass device and into an interior of the fixed bed of the solid particles that is below a top of the fixed bed, wherein the gas exits a distributor portion of the first flow bypass device in a down-flow direction;
- wherein the first flow bypass device additionally has a pipe portion, wherein the distributor portion is connected to a bottom of a pipe portion, and a flow channel is formed within the pipe portion and the distributor portion, wherein openings formed in a bottom of the distributor portion face a bottom of the vessel.
The method for loading solid particles and a flow bypass device in a vessel, wherein loading of the vessel with the solid particles and the flow bypass device comprises:
- placing a first portion of the solid particles into the vessel;
- assembling the flow bypass device on a top of the first portion of the solid particles;
- and filling the vessel with a second portion of the solid particles such that a bottom of the flow bypass device is surrounded by the solid particles, wherein the flow bypass device has a pipe portion and a distributor portion, wherein the distributor portion is connected to a bottom of the pipe portion, and a flow channel is formed within the pipe portion and the distributor portion, wherein openings formed in a bottom of the distributor portion face a bottom of the vessel, and wherein a rupture disk is proximal to the top of the pipe portion.
