Abstract
In the purification of hydrocarbon streams containing HF by chemical reaction with potassium hydroxide, a small portion of the hydrocarbon stream containing HF is passed through a small test bed of solid KOH; and when excess HF is present in the hydrocarbon stream to be purified, the temperature of the test bed increases significantly and rapidly and the flow of hydrocarbon is discontinued to the main treater responsive to the temperature in the test bed thereby preventing the treater temperature from exceeding a preselected maximum allowable value. In one embodiment, the main hydrocarbon charge is by-passed around the main KOH treater and introduced into the effluent from the treater; and in another embodiment, the hydrocarbon charge is returned to a settling zone following alkylation and prior to separation facilities utilized to process the hydrocarbon phase.
