Process Gas Boiler (PGB)
Thermal Analysis
HRST’s thermal analysis software can help your team better understand boiler performance for process upgrades, monitoring service life, and failure analysis. We perform analysis assessments on Process Gas Boilers such as Hydrogen/Syngas PGBs, Sulfur Recovery Units, Tail Gas Incinerators, and Process Gas Coolers.
Offline Inspection Services
HRST can perform inspections on PGBs like Hydrogen Plants, Sulfur Recovery Units, Sulfuric Acid Plants, and Tail Gas Incinerators. We can also provide support for Rotor Air Coolers and Process Gas Coolers. We offer system design review, thermal review, and visual inspections at gas path areas, pressure vessel shell, remote steam drum, and piping. We also work closely with trusted NDE partners to offer shell and drum NDE and tube NDE.
Online Inspection Services
HRST can help your facility utilize up-time to inspect your boilers and turn long durations between turnarounds into proactive monitoring for future maintenance planning. Our online inspection services offer the following:
- System Walkdown
- Infrared (Thermal) Survey
- Burner and Flame Monitoring
- Steam Piping Walkdown
- Boiler Operation and Control Assessment
Advanced Turnaround Inspection Services
Turnaround scopes can become overwhelming. HRST can assist your facility with pre-turnaround assessment and engineering to tackle at-risk areas on a prioritized schedule. Pre-Turnaround Engineering and planning includes critical crack size analysis, flow accelerated corrosion (FAC) assessment, and covered piping systems (CPS) assessment. Turnaround Inspection Execution includes steam vessel weld inspection, FAC UT monitoring, and a CPS inspection.
Waste Heat Boiler (WHB)
Thermal Analysis
HRST’s thermal analysis software can help your team better understand boiler performance for process upgrades, monitoring service life, and failure analysis. We perform analysis assessments on Waste Heat Boilers such as Reformer Furnace WHB, FCC CO Boilers, Thermal Oxidizers, and Coke Furnace WHRU. We provide process and performance upgrades with debottlenecking and thermal performance studies.
Offline Inspection Services
HRST’s WHB inspection services provide comprehensive inspection of your facility’s fixed equipment. We will perform standard visual inspections on common problem areas like flue gas path, pressure vessels, external areas, and piping. We also offer enhanced inspection services with borescope inspection and drone inspection. Both options save time and money during your next outage.
