Process instrumentation is vital for ensuring the safe production of green ammonia. By providing accurate, real-time data on critical parameters some challenges, such as overheating, overpressure, impurities, or leakages, can be addressed properly.
Parameters
Focus on key process parameters
Prevent overheating
Identify hotspots in the reactor and enable precise temperature control by relying on safe and reliable temperature measurement.
Monitoring gas composition is crucial for improving overall plant performance and efficiency. By using Raman spectroscopy, you ensure reliable quantitative measurements of chemical composition.
Multi-point temperature measurement for enhanced overheating prevention
Multiple thermocouples are strategically placed throughout the catalyst bed to detect any abnormal temperature spikes or gradients. The iTHERM multi-point thermometer line provides several benefits, e.g.:
Infinite layouts of 3D sensors distribution for any desired process monitoring configuration
High degree of customization thanks to a modular product design for easy installation, process integration and maintenance
Compliance to different types of protection for use in hazardous locations for easy process integration
The reactor is a prime focus of overpressure protection due to the exothermic reaction and potential for runaway conditions. The smart pressure transmitter Cerabar PMP71B can help prevent overpressurization in the heart of the Haber-Bosch process:
Robust design and Heartbeat Technology verification and monitoring functions to detect unwanted anomalies
Reduce systematic failures thanks to error-free SIL commissioning and instrument guided proof testing
Wireless control of the device in the process area with the SmartBlue App
Rely on Endress+Hauser oxygen analyzer to maintain catalyst efficiency
Oxygen can be a significant issue regarding catalyst poisoning, as even trace amounts of oxygen can cause irreversible damage. With the OXY5500 oxygen analyzer, impurities in the feed gas can be closely monitored. It offers:
Quenched fluorescence (QF) technology for reliable optical measurement with fast response times
Excellent long-term stability and simple operation
Small optical sensor with no membrane or consumable chemicals
Achieve economies in ammonia yield by using Raman spectroscopy
The most critical measurement is the hydrogen-to-nitrogen ratio between the synthesis reactor and the compressor in the recycle stream. Maintaining the proper ratio ensures maximum ammonia formation at each pass. Our Raman Rxn5 analyzer provides:
A rugged, compact design with minimal utility requirements, no sample transport and no consumables
Inline measurement for enhanced operator safety and fast response times
Up to four-channel availability and fiber optic lengths up to 150m
