The Complete System of Air Separation Process Analysis for Model TG-505
It is applied in the synthesis of methane-rich gas with hydrocarbon (Light oil, naphtha, LPG, light hydrocarbon, hydrocarbon-containing dry gas etc.) and steam as raw materials. The resulted gas can be further used to produce hydrogen, syngas with different CO/H2 ratio (for the synthesis of methanol or ammonia etc.) and coal gas.
Product Details
The TG-505 air separation process analysis system plays a pivotal role in air separation equipment and gas purification processes, serving as an indispensable tool for process optimization and quality control. With various types of online analytical instruments installed at different stages to monitor specific gas media, the system provides real-time operational insights into the fractionation tower through instrument outputs.This enables precise control of the production process to achieve optimal conditions for generating oxygen (O₂), nitrogen (N₂), argon (Ar), and cryogenic liquids with specified purity levels, while ensuring high-purity gases consistently meet post-purification quality standards.
The TG-505 Air Separation Process Analysis System is a complete on-line process analysis system specifically designed for air separation or oxygen/nitrogen production processes. In chemical and metallurgical industries, this system is used to extract O2, N2, Ar, and other rare gases from air. Process gas analysis ensures product purity and the smooth operation of oxygen generators, while providing precise parameters of measured gas components to maintain product quality and control process stability
