Powell Duffryn Terminals, Inc. (PDT) operates one of the largest tank farms on the east coast in Bayonne, NJ, handling liquid chemicals for many major chemical manufacturers. A reliable steam supply has become essential for operation, especially for steam tracing lines in the winter, as freeze-ups would prevent the transfer of liquids to and from storage, blending and shipping. Condensate from the steam is also used in the blending operations as a source of distilled water. In 1977, steam was purchased from a neighbor, with no credit allowed for any condensate return. Even after installing two 500 hp boilers, PDT found it most economical to shut down the boilers for the summer and purchase its steam. In 1982, additional chemical storage and blending facilities were added, doubling the capacity. Along with the terminal expansion, the company wanted to find a more economical and more energy efficient steam and condensate return system to reduce its steam usage and thereby cut down on energy costs and waste. PDT installed a high efficiency, reasonable priced steam trap and condensate recovery system consisting of pressure-powered condensate pumps, bimetallic and balanced pressure thermostatic steam traps, automatic thermostats for freeze protection, and liquid expansion temperature regulators. The steam and condensate recovery system has been in operation for five years and has performed well. The nonelectric pressure-powered condensate pumps have performed consistently, requiring only routine maintenance. Although direct cost comparisons for system installation were not prepared, it is estimated that the condensate pumps have saved thousands of dollars by eliminating the special motor controls and power wiring required with conventional electrically operated condensate pumps.
