  • Patent number: 12371972
    Abstract: A method of removing built up scale in a conduit of a geothermal plant, in which conduit a fluid including mineralized water is flowing, is provided. The method includes analyzing the mineralized water and scale. A chelator, acid composition, and/or caustic composition for dissolving the scale is predetermined based on the analysis of the mineralized water and scale. The fluid in the conduit is alternately treated with the acid composition and the caustic composition. The caustic composition includes the predetermined chelator. Treating is carried out without stopping the fluid flow in the conduit. The acid composition and the caustic composition are injected directly into the fluid in the conduit.

    Abstract: The present invention is directed to the use of a quaternized derivative of polyisobutylene as stabiliser in inverse emulsions like inverse emulsions used for a reverse-phase emulsion polymerisation process, e.g. for the polymerisation of acrylamide and ethylenically unsaturated cationic monomers. Such emulsions are e.g. used as flocculant for waste water treatment. The present invention is further directed to inverse emulsions comprising a quaternized derivative of polyisobutylene. The inverse emulsions have sufficiently low viscosity and sufficiently high shear stability. The present invention is further directed to an inverse emulsion polymerisation process, wherein the inverse emulsion comprises a quaternized derivative of polyisobutylene.
