High efficiency powder dispersion and blend system and method for use in well completion operations

A system for dispersing a powder additive within a liquid stream comprising:

• at least one transport bin or transport conduit containing the powder additive and in fluid communication with an air source, the air source conveying the powder additive from the at least one transport bin or transport conduit;
• at least one powder transfer bin receives the powder additive from the at least one transport bin or transport conduit, wherein the at least one powder transfer bin comprises an air-powder conditioner conveying air upwards from a base of the at least one powder transfer bin;
• a powder conduit receives conditioned powder additive from the at least one powder transfer bin;
• an ejector device comprising a liquid conduit, concentric with the powder conduit, located within the liquid conduit, wherein the powder conduit terminates before an annular space of the ejector device, wherein the liquid flows past the powder conduit terminus into the annular space and creates a vacuum which urges the conditioned powder additive out of the powder conduit and disperses it within the liquid to form a mixed liquid,
• a hydration tank receives the mixed liquid from the ejector device;
• and
• a transfer pump pumps the mixed liquid from the hydration tank.
