Abstract
Apparatus for optimizing a treatment for removing organic substances from a chemical process stream wherein known quantities and kinds of organic or other compounds are injected into and dissolved in the stream prior to treatment thereof. Samples of the compounds are extracted from the stream before and after treatment thereof and compared with one another to determine the efficiency of the treatment. The injecting apparatus is one that enables a substance that is at least partially immiscible with the liquid of the stream to be injected into the stream at a velocity sufficiently great to cause adequate dissolution of the substance in the stream.
