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 manufacturing steps are allocated to two different locations A and B and the process comprises the step of transporting an aqueous polyacrylamide gel hold 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 at its lower end, feeds for the aqueous monomer solution, a closable bottom opening, and means allowing to deploy the polymerization unit in a vertical manner.

Abstract: The invention relates to a method for operating a linear concentrator solar power plant (1), in which method a heat exchange medium flows through a pipeline loop (47) with at least one receiver, wherein the heat exchange medium has a flow velocity which is so great that the flow in the pipeline loop (47) is turbulent, wherein at least part of the heat exchange medium is removed upon exit from the pipeline loop (47) and is guided back into the pipeline loop (47). Furthermore, the invention relates to a linear concentrator solar power plant having at least one pipeline loop (47) with at least one receiver, in which a heat exchange medium which flows through the pipeline loop (47) is heated by incoming solar energy, wherein a mixing device (27) is included, in which at least part of the heat exchange medium which flows through the pipeline loop (47) is mixed with heat exchange medium to be fed in.
