Apparatus and Method for Passive Dust Control in a Transfer Chute

Номер: US20120090956A1
Автор: Steven Hays Brobst
Принадлежит: CCC Group Inc

A dust control apparatus and method for a bulk material handling transfer system having a chute comprising a pathway there through for handling varying volumes of bulk material flowing through the chute using gravity flow. A self-adjusting air restrictor gate is mounted in the chute for engaging the upper surface of flowing bulk material through the chute for restricting the air pathway during material volume flow variations to reduce dust emissions. The gate member contacts the upper surface of flowing bulk material and moves up and down in response to the flow of bulk material through the chute to restrict the flow of air to reduce dust. A counterweight mechanism and a damper helps maintain controlled contact of the air restrictor gate with the upper surface of bulk material flowing through the chute.

SEPARATION OF CARBON DIOXIDE (CO2) FROM GAS MIXTURES BY CALCIUM BASED REACTION SEPARATION (CaRS-CO2) PROCESS

Номер: US20130078159A1
Автор: Fan Liang-Shih, Gupta Himanshu, Iyer Mahesh V.
Принадлежит: The Ohio State University

A reaction-based process developed for the selective removal of CO2 from a multicomponent gas mixture to provide a gaseous stream depleted in CO2 compared to the inlet CO2 concentration. The proposed process effects the separation of CO2 from a mixture of gases by its reaction with metal oxides. The Calcium based Reaction Separation for CO2 (CaRS-CO2) process consists of contacting CO2 laden gas with CaO in a reactor such that CaO captures CO2 by the formation of CaCO3. CaCO3 is regenerated by calcination leading to the formation of fresh CaO sorbent and the evolution of a concentrated stream of CO2. The “regenerated” CaO is then recycled for the further capture of CO2. This carbonation-calcination cycle forms the basis of the CaRS-CO2 process. This process also may use a mesoporous CaCO3 structure that attains >90% conversion over multiple carbonation and calcination cycles. 1. A facility separating carbon dioxide and sulfur dioxide from a flow of gas comprising carbon dioxide and sulfur dioxide , comprising:a gas-solid contact reactor receiving said flow of gas;a sorbent within said gas-solid reactor, comprising a metal oxide, said sorbent reacting with said carbon dioxide and said sulfur dioxide so as to convert at least a portion of said sorbent to a metal carbonate and at least a portion of said sorbent to a metal sulfate; anda calcinator, said calcinator receiving said at least a portion of said metal carbonate, said calcinatory calcining said metal carbonate to form said metal oxide and carbon dioxide,wherein said sorbent is replenished in said gas-solid reactor with said metal oxide formed in said calcinatory.2.
