What instrument is used to monitor internal pressure within an industrial ammonia synthesis reactor__________________?
Show answer Hide answer
Answer: A. Bourdon gauge
Explanation
Bourdon gauges are rugged mechanical pressure measuring instruments capable of handling high industrial pressures safely. Ammonia synthesis reactors operate under extreme pressures that require robust elastic metal sensing elements. The C-shaped or helical Bourdon tube straightens predictably under internal pressure to drive a pointer indicator. Ammonia synthesis via the Haber Bosch process requires operating pressures often exceeding 150 atmospheres. Bourdon tubes are constructed from high-strength metal alloys designed to resist fatigue under cyclic pressure loads. Mechanical gauges do not require external electrical power, making them reliable fail-safe indicators in plants.
Chemical fertilizer plants must continuously monitor reactor pressures to maintain safe synthesis conditions. Failure of high-pressure reactor components can cause catastrophic releases, making reliable pressure gauges vital. Routine gauge calibration ensures accurate operator oversight in hazardous high-pressure chemical environments. U-tube manometers contain open liquid columns and cannot safely contain high industrial ammonia synthesis pressures. Inclined tube manometers are designed specifically for measuring very low differential gas pressures accurately. Pirani gauges are restricted to measuring high vacuum ranges and would instantly fail under synthesis pressures.
