Abstract
A slurry injection system includes low and high pressure clear fluid manifolds. Low pressure clear fluid is pressurized and communicated to high pressure manifold. A blender unit communicates slurry through a sensor system that generates a flow rate signal and a density signal of the low pressure slurry. The slurry pressurizer is in fluid communication with the high pressure clear fluid manifold through a bypass pump, a mixer, the blender unit and the low pressure clear fluid manifold. The slurry pressurizer forms high pressure slurry that is communicated to the mixer and communicates fluid to the low pressure clear fluid manifold. The mixer mixes the high pressure slurry and high pressure clear fluid from the high pressure clear fluid manifold to form a mixture that is communicated to a slurry injection site. A controller controls the bypass pump using the flow rate and density to control a density of slurry.
