Abstract
Equipment for dissolving polyacrylamide powder to obtain an aqueous solution thereof for enhanced oil recovery comprises first and second powder storage tanks for storing polyacrylamide powder under nitrogen atmosphere; a gas conveyor unit for carrying the polyacrylamide powder from the first storage tank to the second storage tank by nitrogen gas flow; a constant powder supply unit for receiving the polyacrylamide powder from the second storage tank, metering the powder, and sending the metered powder to a powder dispersion unit for dispersing in water the polyacrylamide powder. A first liquid supply unit sends the dispersion or solution of polyacrylamide powder obtained from the powder dispersion unit to a dissolution tank for completing dissolution of the polyacrylamide; and a second liquid supply unit transfers the polyacrylamide solution from the dissolution tank to a solution storage tank for storing the polyacrylamide solution. A filtration unit is connected in the liquid supply line between the dissolution tank and the solution storage tank; and a nitrogen gas supply system maintains the interiors of these units filled with nitrogen gas at a pressure higher than atmospheric pressure.
