Critical Process Measurements

Natural Gas Feed Monitoring

Maintain the optimum steam-to-carbon ratio by continuously measuring:

• Methane (CH₄)
• Carbon dioxide (CO₂)
• Carbon monoxide (CO)
• Hydrogen (H₂)
• Nitrogen (N₂)

Benefits:

• Improved reformer efficiency
• Lower fuel consumption
• Reduced catalyst stress
• Improved syngas quality

Comprehensive Process Monitoring

The MAX300-RTG provides real-time analysis of all major process streams in ammonia or methanol production, enabling tight control over critical parameters:

• Natural Gas Feed: Calculates the steam-to-carbon ratio to ensure efficient reforming
• Ammonia Converter Inlet: Provides rapid, full-spectrum composition analysis to maintain the optimal H₂:N₂ ratio, achieving a ±0.01% tolerance
• Hydrogen Recovery Unit Effluent: Enables optimization of inert gas purging
• Recycle Streams: Detects methane slippage and inert gases quickly to support safe, efficient operation
• Process Control: Delivers fast, accurate data to optimize process algorithms and reduce stress on critical equipment such as compressors

By monitoring and controlling these key variables in real time, the MAX300-RTG ensures tighter process control, greater operational stability, and higher yields.

In ammonia production, the MAX300-RTG is used to tightly control four key process variables:

• Steam-to-carbon ratio
• Hydrogen-to-nitrogen (H₂:N₂) ratio
• Methane slippage
• Process inert gases
