AMMONIA HEATER REVAMP

XRG provided an engineering study, equipment supply, and installation services to revamp an ammonia heater in Iowa.

The Problem: The convective heater was able to flow approximately 115 ton/h of anhydrous ammonia before the desired product outlet temperature started dropping below specification (34°F). The site reported long flames at maximum heat release that visually seemed to impinge on the coil. The customer wanted to increase the capacity of the heater from 115 to 165 ton/h.

XRG performed a study to investigate the reason for the limited capacity and made recommendations for optimization, keeping in mind the mechanical and process constraints of the heater’s current configuration.

The Solution: Based on the recommendations provided by XRG, the customer opted to the first step of replacing the coil bundle with upgraded metallurgy and upgraded the blower motor to increase the burner capacity to 28 MMBtu/h.  These changes allowed them to increase process flow to 150 ton/h. XRG is continuing to work with our customer to develop the next phase of optimization to achieve 165 ton/h in the most cost effective manner.

XRG’s turnkey solutions allowed the ammonia terminal to have minimal down time and was completed in time for the ammonia season.
