Upstream Oil & Gas

Process heating helps upstream operators separate produced fluids, prevent hydrates and freezing during pressure reduction, dehydrate natural gas, stabilize condensate, heat tanks, and safely destroy waste gas. That heat comes from fired equipment such as line heaters, heater treaters, glycol dehydrators, gas production units, combustors, and flares.

Burner management systems are used on upstream fired equipment that needs controlled ignition, flame supervision, temperature control, and safe shutdown. That includes line heaters, heater treaters, glycol dehydrators and TEG reboilers, gas production units, heated separators, heated tanks, combustors, ECDs and VDUs, flares, and condensate stabilizers.

Line heaters heat the well stream before pressure reduction, where the temperature drop can cause hydrate formation, freezing, and flow interruptions. A burner management system helps the heater light off safely, prove flame, hold water bath temperature, and shut fuel off if unsafe conditions are detected.

A BMS will not prevent every trip, but it shortens the time between a trip and an answer. Clearer alarm information, time-stamped event history, and shutdown diagnostics help operators identify the cause remotely, which matters most on sites that are hours from the nearest technician.

On upstream firetube equipment, natural draft is the common default. The burner pulls combustion air through the firetube and stack with no fan. Forced draft adds a blower and generally requires airflow proving, purge timing, and matched shutdown logic, which is where PF2200-FD or PF3100 come in. For a fuller comparison of the two approaches, see our guide to natural draft and forced draft burners.

It depends on draft type and complexity. PF2150 covers natural draft, single fuel train firetube applications such as line heaters, treaters, and dehydrators. PF2200 adds forced draft support, deeper diagnostics, data logging, and advanced PID. PF3100 handles multi-burner, multi-pilot, and fuel/air ratio control on more complex upstream and facility equipment. You can compare the controllers side by side.

A fuel train regulates fuel pressure and flow to the pilot and main burner, and provides the shutoff capability the burner management system relies on. Upstream fuel gas is often wet, sour, or inconsistent in pressure, so freeze protection on pilot lines, regulators, and orifices becomes a practical concern. Double-Block arrangements and pre-assembled designs support controlled light-off and repeatable shutdown across repeat equipment packages.

Profire supports upstream fired equipment such as line heaters, heater treaters, glycol dehydrators and TEG reboilers, gas production units, heated separators, heated tanks, combustors, ECDs and VDUs, flares and flare ignition systems, and condensate stabilizers. The right controller depends on draft type, burner count, fuel train design, and how the unit needs to report back.

Yes. Many Profire burner management systems support Modbus RS-485 communication with SCADA or site control systems, depending on the controller and configuration. On remote upstream sites, that visibility is often the difference between knowing why a unit tripped and sending someone out to find out.

Excess air, poor flame shape, and unstable combustion waste fuel and shorten firetube life. Secondary air control lets a technician adjust the air side to the burner and load instead of running rich or lean by default. The M7 High Efficiency Airplate, part of the M7 High Efficiency Burner system, supports graduated air adjustment on firetube equipment and can boost combustion efficiency by 30%. For more on tuning combustion across applications, see improving combustion efficiency with Profire controllers.

Operators should consider the fired equipment type, burner configuration, fuel train design, draft type, fuel gas quality, shutdown requirements, communications, and spare parts support. On remote upstream sites, add one more question: when this unit trips overnight, what will the field team be able to see before they drive out? Profire helps upstream teams work through that scope with application review, startup and commissioning, and field service.

Alberta’s Directive 060 governs flaring, incinerating, and venting at upstream petroleum wells and facilities, including some gas-conveying pipeline installations. Recent updates introduce requirements around flare ignition, flare maintenance programs, and reporting. Profire can support planning through ignition reliability, retrofit scoping, event history, and documentation. Compliance determinations rest with the operator and the AER.
