A process for producing aqueous polyacrylamide solutions by polymerizing an aqueous solution comprising at least acrylamide, to obtain an aqueous polyacrylamide gel, and by dissolving said aqueous polyacrylamide gel in water, wherein the manufacturing steps are divided into two different locations A and B, and the process comprises the step of transporting an aqueous polyacrylamide gel maintained in a transportable polymerization unit from a location A to a location B. The transportable polymerization unit comprises a cylindrical upper part, a conical part in its lower end, feeds for the aqueous monomer solution, a bottom opening that can be closed, and means that allow the polymerization unit to be implemented vertically. |
