    Abstract: Process for producing hydrophobically associating polyacrylamides Summary Process of manufacturing hydrophobically associating polyacrylamides comprising at least acrylamide or derivatives thereof and an associative monomer by adiabatic gel polymerization of an aqueous monomer solution, wherein the concentration of the monomers in the aqueous solution is from 1mole / kg to 3.3 mole / kg, relating to the total of all components of the aqueous monomer solution. The process yields hydrophobically associating polyacrylamides having an improved viscosity efficiency. Hydrophobically associating polyacrylamides obtainable by the process of the present invention and use of such hydrophobically associating polyacrylamides for oilfield applications, in particular for enhanced oil recovery, conformance control and hydraulic fracturing.

    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: Proceso y planta para elaborar poliacrilamidas mediante la polimerización de una solución acuosa que comprende al menos acrilamida y ácido acrílico o sales de estos en presencia de iniciadores para la polimerización por radicales en condiciones adiabáticas, en donde la acrilamida y el ácido acrílico se almacenan en el sitio de la planta como soluciones acuosas diluidas en tanques resistentes a la presión, y también el recipiente de mezcla de monómeros y el recipiente de polimerización son resistentes a la presión. La combinación de usar soluciones diluidas de monómeros y tanques resistentes a la presión asegura que incluso en caso de una polimerización involuntaria e incontrolada, tales recipientes no exploten y no haya derrames fuera de la planta en el medioambiente.
