Abstract:
A method of forming a product stream having a predetermined concentration of a specified component, comprising the steps of:mixing component streams at least one of which contains said specified component to form a first intermediate mixture stream having a lower concentration of said specified component than said predetermined concentration;introducing a stream of said specified component into said first intermediate mixture stream to form a second intermediate mixture stream;blending said second intermediate mixture stream to produce a third intermediate mixture stream;measuring the concentration of said specified component within said third intermediate mixture stream;metering said introducing of said stream of said specified component into said first intermediate mixture stream so that said third intermediate mixture stream contains said specified component in said predetermined concentration;introducing a recycle stream into said third intermediate mixture stream to form a liquid mixture stream;dividing said liquid mixture stream thereby forming said recycle stream and a final product stream having said predetermined concentration of said specified component; andcontinually recycling said recycle stream into said third intermediate mixture stream.
