Metering & Regulation Stations
Natural gas transmission involves high pressures that must be lowered safely through the use of regulation station heaters. The pressure reduction causes the temperature to drop by about 1°F for every 15 PSIG (or 1°C per 2 Bar) drop. Typical pressure drop ranges from 200PSIG to over 1000 PSIG. Even in warm conditions of 85°F/29°C, a pressure drop of 800 PSIG / 55 bar would mean the gas temperature would be 29°F / -1.6°C. As the weather cools in the fall, a smaller pressure drop of 300 PSIG / 20.6Bar would have the same impact. These freezing temperatures can cause ice formation in the transmission line or the gas instruments to be damaged.
Regulation station heaters such as Bruest’s Twin-Pak, Freez-Fiters, and HOTCAT heaters are the ideal solution for these applications. For smaller pressure drops with the smaller temperature loss, the Twin-Pak family of heaters are easy add on solutions. They can be added without interrupting the service with their compact and easy installation design. The Freez-Fiter fuel gas heaters are suitable for small volume applications with higher pressure drop. These compact, lightweight, silent heaters can provide additional heat with minimal impact to the system design. Finally, the HOTCATs, up to 3.5MMBTU input, are suitable for high volume, high pressure loss applications. They can even be integrated with complete regulation and metering for a simple plug and play solution.
