The Problem

Ensign was experiencing nuisance shutdowns with limited safety I/O. The heater was going down 2-3 times a day due flame failure. Operators and I&E personnel were constantly manually relighting the heater 2-3 times day! Ensign required a safe and reliable solution that met their budget.

Before Profire

The Profire Solution

Ensign needed to meet several safety standards (NFPA, ASME & API560). Profire proposed our 3100 Platform due to the complexity and I/O concentration of the project. Numerous discussions revolved around the accurate temperature measurement from the distillation column located 380' away from the heater. Our design included a quad thermocouple and split the redundant temperatures on redundant networks. 12 individual fuel trains control 12 independent temperature controls valves. This allowed the client to see a 45%+ gas savings due to proper gas regulation and modulating controls for each burner!

Key Products Used

PF3100 Burner Management System

Profire's PF3100 can be specified to work with both natural draft and forced draft applications. Integrated fuel/air ratio controller, combined with optical flame detection.

401AP Fuel Train

401AP offers the complete package for safety and control. Using Profire’s 4-20 mA actuated TCV, 6.5 C/I approved solenoids, and double-block main shutdown, the 401AP allows safe ignition, soft start, consistent temperature control, and emergency shutdown.
