Method for producing a liquid mixture having a predetermined concentration of a specified component

摘要

A method and apparatus for producing a liquid mixture in which mixture components are mixed to produce a product stream having a predetermined concentration of a specified component. This mixing occurs within a fluidic network designed such that the components mix in inlet branches to form a first intermediate mixture having a lower concentration than that desired in the product stream. The specified component is metered into the intermediate product stream to produce a second intermediate product stream that is blended to produce a third intermediate product stream. The concentration of the specified component within the third intermediate product stream is measured and the metering pump is appropriately adjusted. The third intermediate product stream then passes through a recycle loop in which recycled product is mixed with an intermediate product stream to produce a liquid mixture stream that is divided into the recycle stream and a product stream.
