BRISTOL, RI — (Marketwire) — 12/04/12 — has introduced a static mixer for bitumen processing that mixes multiple diluents to the correct viscosity and density, allowing pumping over a wide range of flow rates.The for , viscosity, and density control is combined with their wafer-style static mixer to achieve a low CoV (coefficient of variation) of injected diluents. Capable of achieving a uniform concentration of injected materials within a short downstream distance, while meeting the maxim
