  • Patent number: 8992729
    Abstract: A method and assembly for separating contaminants from liquids, such as condensates, or vapors at an evaporation plant. The contaminants are separated from liquids by stripping when bringing a contaminant-enriched liquid into direct contact with a vapor by spraying or distributing the liquid into the vapor flowing in a vapor duct or onto wall surfaces in the vapor duct thus reducing the contaminant-content of the sprayed liquid and producing a cleaner liquid. The contaminants are enriched in the vapor. From vapors contaminants are separated by absorption when bringing a contaminant-enriched vapor into direct contact with a cleaner liquid by spraying or distributing the liquid into the vapor flowing in a vapor duct or onto wall surfaces in the vapor duct thus increasing the contaminant-content of the liquid, but producing a cleaned vapor.

  • Patent number: 6473997
    Abstract: The invention relates to a method and a drying section for dewatering a fibrous web (9), the drying section preferably being intended to dry fibrous webs in a paper machine, and the drying section comprising a number of drying cylinders (8), by which an inlet and outlet nip are formed when running the fibrous web, and the drying section comprising drying devices for decreasing the moisture content of the fibrous web, the drying devices comprising a blow device for blowing air in the proximity of the surface of the fibrous web.
