Detailed description

1. Overview

Industrial gases refer to oxygen, nitrogen, argon, neon, helium, krypton, xenon, hydrogen, carbon dioxide, acetylene, natural gas, etc. Due to their inherent physical and chemical properties, these gases occupy a crucial position in the national economy, and their promotion and application speed is very fast, penetrating almost all industries.

In order to ensure the safe and stable operation of the air separation unit, achieve the required purity of the product, and achieve high efficiency and energy conservation, it is very important to accurately and timely understand the gas composition of each process control point in the production process. Therefore, it is necessary to set up an online analyzer to detect the gas composition of each process control point in real time. Online gas analysis instruments can directly control the quality of the production process of air separation equipment, which is an important means to improve product output and quality, and also an important guarantee for the safe operation of air separation equipment. Therefore, they play a very important role in the instrument and control system of air separation equipment. Meanwhile, online gas analysis instruments are a relatively expensive type of instrument, so it is of great significance to configure appropriate analysis points and select appropriate models of analytical instruments to ensure the reliability of the device and reduce investment.

The TR-9500 air separation process analysis system is professionally designed for analyzing key locations in the gas production process of the air separation industry. It can be used for purifying raw material air, analyzing product gas purity, analyzing product trace impurities, analyzing N2 and O2 in argon, analyzing nitrogen in the lower tower and O2 in the liquid air, analyzing hydrogen and carbon impurities in the main cooling liquid, and analyzing trace H2.
