  • Patent number: 9050576
    Abstract: A device, comprising a conduit for an aqueous stream, a mixing tube located inside the conduit, having a static mixer inside the mixing tube, an outlet open to the conduit and an inlet, a sulphuric acid supply tube connected to the inlet of the mixing tube and a hydrogen peroxide supply tube, arranged inside the sulphuric acid supply tube and having an outlet for hydrogen peroxide at the inlet of said mixing tube, and a method, where an aqueous stream is passed through the conduit of the device, 85 to 98% by weight sulphuric acid is introduced to the sulphuric acid supply tube of the device and 50 to 80% by weight aqueous hydrogen peroxide solution is introduced to the hydrogen peroxide supply tube of the device, provide a dilute aqueous solution of peroxomonosulphuric acid without a risk of exposing operating personnel to concentrated peroxomonosulphuric acid.

  • Publication number: 20070028571
    Abstract: The lubricant coalescing filter element is provided that includes a cylindrical outer screen member, at least one filter element disposed inside the cylindrical outer screen member and being coaxial with the outer screen member, and a drainage arrangement disposed between the cylindrical outer screen member and the at least one filter element to drain accumulated lubricant out of the at least one filter element.

  • Patent number: 7032410
    Abstract: A compression system including a compressor driven by a motor, an optional accumulator, a liquid/gas separator, heat exchangers in the form of a condenser and an evaporator, expansion valves and conduit in the form of piping to connect these components together. The liquid/gas separating means is a lubricant separator, typically a cylindrical horizontal or vertical vessel used in conjunction with a gas compressor. The lubricant separator accepts discharge flow from the compressor which includes a mixture of a “smokeless” lubricant and refrigerant gas in a range of particle sizes forming a fluid stream, separates the refrigerant gas from the lubricant and collects the lubricant for reuse in the compressor. Because the lubricant used in the lubrication system rapidly agglomerates into larger size droplets and does not produce an aerosol, the separator does not require a coalescer element to coalesce aerosol and does not require a manway for serving the coalescer element.
