PROCESS TO PRODUCE AQUEOUS POLYACRYLAMIDE SOLUTIONS |
abstract |
The process for producing aqueous solutions of polyacrylamide by polymerizing an aqueous solution comprising at least acrylamide obtained by hydrolysis of acrylonitrile in water in the presence of a biocatalyst capable of converting acrylonitrile into acrylamide, to obtain an aqueous polyacrylamide gel, and by dissolving said aqueous polyacrylamide gel in water, wherein the manufacturing steps are distributed in 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 location A to a location B. The aqueous polyacrylamide gel also comprises at least one stabilizer to prevent polymer degradation. |
