Why Choose Nitric Acid Plant Operations & Emissions Control Training Course?
Nitric acid plants convert ammonia into acid through catalytic oxidation and absorption. Plant performance depends on coordinated control of ammonia and air supply, catalyst condition, heat recovery, absorption and tail gas treatment. An upset can affect acid strength, production rate, equipment reliability and emissions at the same time.
This Nitric Acid Plant Operations & Emissions Control training course gives operators and engineers a plant-wide approach to monitoring performance and investigating problems. It addresses NOₓ and N₂O separately, since their formation and control differ, and considers how emissions systems interact with normal plant operation. The content is applicable to common nitric acid plant configurations, with operating decisions guided by each facility’s design and procedures.
What are the Goals?
By the end of this course, participants will be able to:
- Explain the main stages of nitric acid production and their operating relationships.
- Interpret key variables affecting ammonia oxidation, absorption and acid quality.
- Recognise common causes of lost production and unstable operation.
- Distinguish the principal sources of NOₓ and N₂O emissions.
- Evaluate the operating performance of absorption and emissions control systems.
- Apply a structured approach to diagnosing process and emissions deviations.
- Identify opportunities to improve energy efficiency, reliability and environmental performance.
Who is this Training Course for?
This course is designed for:
- Nitric acid plant operators, shift supervisors, process engineers and production managers.
- Environmental specialists, technical services personnel, maintenance and reliability engineers, and professionals supporting nitrate fertilizer production
How will this Training Course be Presented?
The course combines process flow reviews, operating trend analysis, emissions case studies and group troubleshooting exercises. Participants will examine how a change in one process section affects acid production, energy recovery and tail gas performance.
