4479927 REGENERABLE COLD TRAP FOR ALUMINUM CHLORIDE EFFLUENT Barry Gelernt Corporation
assigned to The Perkin-Elmer
A process for removing sulfur oxides from waste gas is provided. The gas is contacted with an activated sodium carbonate sorbent and, utilizing an alkaline ammonia liquor so as to reduce the flow rates and loss of alkalinity, the spent sorbent is regenerated with an alkaline earth metal oxide or hydroxide.
4482369
Aluminum chloride gases and other gases from a processing system are directed to a cold trap including a blower connected thereto. The blower directs the gases, except for the aluminum chloride, out of the cold trap. The aluminum chloride is solidified in the trap. Means including a heater are provided to convert the solid aluminum chloride to a vapor and selectively empty the aluminum chloride out of the cold trap into another trap associated with means for chemically treating the aluminum chloride. The cold trap is then cooled and ready to receive additional aluminum chloride from the processing system.
4481172 PROCESS FOR REMOVAL OF SULFUR OXIDES FROM WASTE GASES Philip S Lowell, James L Phillips assigned to Environmental Elements Corp
PROCESS FOR PRODUCING A HYDROGEN-RICH GAS STREAM FROM THE EFFLUENT OF A CATALYTIC HYDROCARBON CONVERSION REACTION ZONE Don Carson, Robert B James assigned to UOP Inc
A process for the production of a hydrogen-rich gas stream from the effluent of a catalytic hydro carbon conversion reaction zone is disclosed. A hydrogen-containing vapor phase is recovered from the effluent and subjected to cooling ir order to produce a hydrogen-rich gas stream The resulting hydrogen-rich gas stream is ex. panded to provide the medium used in cooling the hydrogen-containing vapor phase.
