Abstract
A method of dosing a system with HCL is provided. The method includes at least two parallel trains. The method utilizes a first operating mode, wherein at least one primary train is actively providing HCL to an end user, and at least one secondary train is either inactive or also providing HCL to the end user. The method utilizes a second operating mode, wherein the least one primary train is evacuating the contents of the train to a disposal system, and the at least one secondary train is providing HCL to the end user. And the system utilizes a third operating mode, wherein the at least one primary train is purging the train, and the at least one secondary train is providing HCL to the end user. The first operating mode, the second operating mode, and the third operating mode are controlled by an electronic monitoring and control system.
