Improved Air Control and Furnace Safety

REXA recently conducted a successful installation on a crude unit heater at a refinery in California. Furnaces help refineries and petrochemical plants break down and convert hydrocarbon fluids into fuels or chemicals such as gasoline, diesel, ethylene, and propylene. When making process improvements, these facilities tend to overlook improving furnace draft control. There are many instruments to choose from when optimizing the draft in a process heater. The challenge is safely elevating process fluid temperature to a target level, maximizing thermal efficiency and throughput and reducing O2, CO and NOx emissions.
