Why should the argon content be measured when the syngas is exported?
Argon is an inert gas and does not participate in the reaction during the purification and transformation process. After argon enters the synthesis, it is compressed together with hydrogen and nitrogen. Its high content wastes energy. Increase production costs. Measuring the argon content at the syngas outlet can also reflect the oxygen purity. A high argon content indicates a decrease in oxygen purity.
The argon content, coupled with the gas composition, can be used to determine whether the oxygen-to-coal ratio is appropriate when the gasifier is operating, as well as the oxygen concentration and even the concentration of coal slurry.
The main source of argon is that oxygen is carried in. It is an ultra-inert gas. Under conditions such as a gasifier (even if an element in the coal may have a catalytic function) it does not participate in the reaction. To detect it, the main purpose is to check the purity of the oxygen and then select the recovery capacity.
How accurate is the measurement of argon gas? The amount should be very small, usually several orders of magnitude.
In our unit, inert gas, called purge gas, must be discharged from time to time, and the main controller is responsible for these tasks. Too high content affects the synthesis efficiency of ammonia.
consult: If there is a liquid nitrogen washing process in the purification section, is it necessary to detect the argon component in the gasified syngas? Thank you 6# for the eternal ideal
