Abstract: Disclosed are oleyl propylenediamine-based compounds used in compositions and methods for inhibiting corrosion. The method comprises introducing into a fluid source a composition comprising one or more oleyl propylenediamine-based compounds comprising Formula I: wherein Y1, Y2, and Y3 independently are hydrogen or a substituent of Formula (II): wherein V is —O— or —NH—, W is optionally present and is a linear or branched C1-10 aliphatic group, X is —H, —NZ3+, —COOH, —SO3H, —OSO3H2, —PO3H, —OPO3H2, or a salt thereof, each Z independently is hydrogen or a linear or branched C1-20 aliphatic group optionally interrupted or substituted with one or more oxygen atoms, and R is hydrogen or methyl, provided that at least one of Y1, Y2, or Y3 is a substituent of Formula (II).

Abstract: Methods for recovering energy and water from at least one energy-rich process water stream are provided. The methods optionally incorporate the use of filtration, reverse osmosis, ion exchange, water softening, forward osmosis, and membrane distillation. The methods can be used to recover energy and water from blowdown or condensate from a water-containing industrial process, which in certain embodiments may be a boiler system.
