SCS-900B Air Separation

Air separation plants are widely used in the process industries - metallurgy, special gas, petrochemicals, coal chemical, glass, semiconductors, aerospace, nuclear applications and other needs of various industries. In order to make the air separation plant run in the best condition, the online analysis technology must be used to accurately and timely grasp the gas composition of each process control point in the air separation production process so as to achieve the purpose of ensuring product quality, energy efficient and safe and stable production. The SCS-900B gas analysis system integrates advanced analytical techniques and sound systems with extensive applications and unique advantages.
