Case Study

Cataract Steel was engaged to deliver a natural gas heating solution to help deliver gas through transmission lines.

The solution was a heater that utilize the natural gas being transmitted through the lines to feed an internal combustion engine. A portion of the gas in the customer's 1,200 psig transmission line is branched off and heated to 128 degrees Fahrenheit. The pressure of the heated gas is then reduced to 150 psig, with that fuel being used to run a natural gas engine that drives a gas compressor that forces the product farther down the transmission line.
