Method and apparatus for injecting a chemical into a process upstream of an inline mixer

摘要

A new and unique inline mixer and process pipe combination includes an inline mixer with a casing and a rotor arranged therein. The casing has one or more stationary vanes and an inlet connected to a process pipe configuration. The rotor has one or more rotary vanes that rotate on an axis of rotation in the casing. The process pipe configuration includes a chemical injection pipe having a slotted injection pipe arranged therein having an outer surface with a long narrow slot therein oriented substantially parallel to the axis of rotation of the rotor for injecting a chemical into a process flow media flowing in the process pipe configuration. The long narrow slot is located on a downstream side of the outer surface and oriented in a plane parallel to the direction of flow of the process media.
