Abstract
An HF alkylation unit incorporates a source of a proton acceptor additive which may be added to the HF alkylation acid in the event of a release of acid from the unit. The addition of the proton acceptor to the acid alters the character of HF droplets in an HF cloud to make them more easily treated by a simple water drench. The proton acceptor is maintained in a pressurized container in the unit and is connected to the reaction section of the unit by way of additive release valves under the control of an emergency controller which opens the valves and permits the additive to enter the reaction section of the unit and mix with the acid to modify its characteristics. The container may be connected to the major acid-containing process vessels in the unit, specifically the acid settler and the acid cooler (in a gravity flow unit) or the acid settler and the reactor (in a pump-around unit).
