Gas analysis is the most common and widely used means of production control in the processing and production of synthetic ammonia. A timely and accurate understanding of the content of each component of production gas is of great significance for stable production, production increases, reducing consumption, quality improvement and avoiding accidents.
Here are two examples of gas-making and synthesis sections which briefly show the application of a gas analysis system in the ammonia synthesis industry.
Raw coal is intermittently fed into the gas generator. Air is filled into the furnace and the temperature of the furnace is raised. Then the steam and nitrogen-added air are added into it and changed into semi-water gas. The semi-water gas is put into the scrubbing tower for dust removal and cooling, and finally pumped into the semi-water gas holder.
The detection of oxygen content in the gas-making section is mainly for safety control. Semi-water gas contains a large number of combustible gases such as carbon monoxide, hydrogen, etc. If the oxygen content exceeds 0.8%, it can create a safety hazard.
