Abstract
Official abstract text for this publication.
In an example, a method of butadiene sequestration includes receiving an input stream that includes butadiene. The method includes directing the input stream to a first sulfur dioxide charged zeolite bed for butadiene sequestration via a first chemical reaction of butadiene and sulfur dioxide to form sulfolene.
First claim
Opening claim text (preview).
1 .- 12 . (canceled) 13 . A butadiene sequestration system comprising: a first fluid interface to receive an input stream that includes butadiene; a first sulfur dioxide charged zeolite bed to sequester butadiene from the input stream via a chemical reaction of butadiene and sulfur dioxide to form sulfolene; and a second fluid interface to provide an output stream from the first sulfur dioxide charged zeolite bed. 14 . The butadiene sequestration system of claim 13 , further comprising a second sulfur dioxide charged zeolite bed to sequester butadiene from the input stream via a chemical reaction of the butadiene and sulfur dioxide to form sulfolene. 15 . The butadiene sequestration system of claim 14 , further comprising: a butadiene detector to monitor butadiene in the output stream; a control device communicatively coupled to the butadiene detector, wherein the control device is configured to send a valve positioning signal to a valve responsive to a determination that butadiene detected in the output stream exceeds a butadiene threshold, and wherein the valve is configured to direct the input stream to the second sulfur dioxide charged zeolite bed for butadiene sequestration responsive to receiving the valve positioning signal. 16 . The butadiene sequestration system of claim 15 , wherein the control device includes a programmable logic controller (PLC) device, and wherein the valve positioning signal includes instructions to close a first fluid path to the first sulfur dioxide charged zeolite bed and to open a second fluid path to the second sulfur dioxide charged zeolite bed. 17 . The butadiene sequestration system of claim 13 , further comprising: a second fluid interface for removal of the sulfolene from the first sulfur dioxide charged zeolite bed; and a third fluid interface for providing additional sulfur dioxide to the first sulfur dioxide charged zeolite bed for butadiene sequestration. 18 .- 20 .
