Abstract

Process for producing aqueous polyacrylamide solutions by polymerizing an aqueous solution comprising at least acrylamide thereby obtaining an aqueous polyacrylamide gel and dissolving said aqueous polyacrylamide gel in water, wherein the process is carried out in a modular, relocatable plant. The plant preferably is deployed at a location at which aqueous polyacrylamide solutions are used, for example on an oilfield or in a mining area.
