  • Patent number: 4476097
    Abstract: Hydrocarbon vapors containing HF, as from an HF alkylation refrigerated vent gas yield, the reactor settler, and the like are charged to a liquid knock-out drum to remove entrained liquid therefrom, the recovered liquid being pumped to storage in response to liquid level control on the knock-out drum. Recovered vapors are charged to a circulating aqueous caustic treater to yield HF-free vapors, as to a flare. The circulating caustic solution is indirectly heated in response to a preselected caustic solution temperature to prevent freezing. A high pressure rupture disc, upstream from the knock-out drum, affords a vapor relief safety by-pass of the treater. Dry gas, such as nitrogen or sweet, natural gas, continuously sweeps the relief line to maintain this line open and operable.
    Type: Grant

  • Patent number: 4224283
    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 increase 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.
