Latest Patents

Harden holds a patent for the "Removal of bromine from gaseous hydrogen bromide." This patent describes processes and systems for effectively removing free bromine from gaseous anhydrous HBr contaminated with free bromine. One of the processes involves feeding the contaminated HBr into countercurrent contact with at least one liquid alkylaromatic hydrocarbon within a packed section of a column. This process maintains free radical bromination conditions, resulting in the production of liquid a-bromoalkylaromatic compounds along with gaseous HBr. Another process utilizes at least two scrubbers to scrub the gaseous anhydrous HBr substantially free of bromine, each containing a different specified type of scrubbing liquid.
