Abstract
A method and apparatus for improving mixing of fluids has at least two static mixing stages connected in series with a bypass valve connected in parallel across each but the last of the mixing units. The capacity of each downstream mixing unit should be such that its minimum flow requirements overlap the opening point for the check valve of the preceding mixing unit. Pressure drops exceeding predetermined limits cause the bypass valves to open allowing fluid flow therethrough thereby preventing further pressure drop through the mixing unit.
