Processes for treating effluent streams in alkylation processes are described. One or more process streams rom HF alkylation processes, HSOalkylation processes, or ionic liquid alkylation processes can be thermally oxidized in a thermal oxidation system. The thermal oxidation system can replace at least one of the caustic wash unit, the neutralization unit, and the acid gas treatment unit. 1. A process for treating off-gas and waste effluent streams in an alkylation complex comprising:{'claim-text': {'sub': ['2', '2', '2', '2', '2', '2', '2', '2', '3', '2', '4', '2', '3', '2', '3', '4', '3', '2', '2', '2', '3', '2', '4', '2', '3', '2', '3', '2', '2', '3', '3', '4'], '#text': 'thermally oxidizing the at least one of: the acid ASO stream from the liquid acid alkylation process section, the acid gas stream from the liquid acid alkylation process section, the acid liquid stream from the liquid acid alkylation process section, the acid spent ionic liquid from the ionic liquid alkylation process section, the acid gas stream from the ionic liquid alkylation process section, the neutralized ASO stream from the caustic wash zone, and the spent caustic stream from the acid gas scrubber zone; or the acid liquid stream from the ionic liquid alkylation process section, the neutralized spent ionic liquid from the ionic liquid caustic wash zone, and the spent caustic stream from the acid gas scrubber zone, in a thermal oxidizing section forming flue gas consisting essentially of at least one of HO, CO, N, O, SOx, NOx, HCl, Cl, HF, F, NaO, NaSO, NaSO, NaCO, NaCl, NaF, CaF, CaO, CaSO, CaSO, CaCO, CaCl, KO, KSO, KSO, KCO, KCl, KF, AlO, NiO, FeO, FeO, FeO, FeO, and CuO;'}, '#text': 'thermally oxidizing at least one of: an acid soluble oil (acid ASO) stream from a liquid acid alkylation process section, an acid gas stream from the liquid acid alkylation process section, an acid liquid stream from the liquid acid alkylation process section, a neutralized ASO stream from a caustic wash ...
