Title:
MIXING TANK AND METHOD OF USE
Document Type and Number:
WIPO Patent Application WO/2012/068352
Kind Code:
A3
Abstract:
A method of transmitting a fluid into an oil well bore provides a frame supporting a vessel, the vessel having an interior, upper and lower end portions, a conically shaped side wall, and an outlet for discharging the fluid from the vessel. A viscous polymeric material is added to the vessel interior. A discharge pipe having a vertical section is placed below the vessel, the discharge pipe being in communication with the outlet. A positive displacement pump is contained within the discharge pipe. The pump transmits fluid from the outlet into the discharge pipe downstream of the vertical pipe section or pump. The fluid is selectively transmitted to either the vessel interior (for recirculating) or into the well. Air is added to the discharge flow line downstream of the pump. In one embodiment, the vessel contains a flexible bladder or bag that holds the material to be pumped. Air pressures the interior to collapse the bladder or bag, thus helping to force the contents of the bag (i.e. material to be pumped) through a provided discharge outlet.
