An indirect dry cooling system suitable for steam condensing applications in a power plant Rankine cycle includes an air blast chiller having a plurality of interconnected modular cooler cells. Each cell includes a blower and tube bundle including inlet headers, outlet headers, and plurality of tubes extending between the headers. In one embodiment, the tube bundles form an A-frame cell construction being structurally self-supporting from a base. Each of the tubes may be finned. Cooling water circulating in a closed flow loop on the tube side between the air blast chiller and turbine steam condenser is cooled by ambient air blown through the tube bundles. The cooled water flows through a second tube bundle in the condenser which condenses steam. The heated cooling water returns through the air blast chiller to complete the cooling water cycle.

A membrane-based heat and mass exchanger includes a plurality of slats where each slat has at least one membrane support structure, a plurality of grooves, at least one first inlet port and one first outlet port for a first fluid, and at least one second inlet port and at least one second outlet port for a second fluid. O-rings or gaskets shaped to match the plurality of grooves are inserted and a plurality of selective membranes is secured to the slats over the supports. The assembly is secured using bolts or clamps for compressing the slats and the selective membranes into an assembly of slats. The slats can be plastic and can be formed from multiple plastic sheets that are welded together to form structures for supporting and channeling fluids through the sheet. The sheets can display a serpentine surface for mixing of fluids under flow.

A depressurization and cooling system for steam and/or condensable gases located in a containment. The system contains a steam condenser having an upstream port connected to the containment through an exhaust line and a downstream port connected to the containment through a backfeed line. The backfeed line contains a backfeed compressor. A re-cooling system for re-cooling the steam condenser is provided. The depressurization and cooling system is effective for re-cooling of the steam condenser. Accordingly, this is achieved as the re-cooling system is self-sustainable.
