Key Highlights Definition: Degassing removes all residual ammonia from cylinders, tonners, and ISO tanks before maintenance, inspection, hot work, or disposal as empty vessels. Primary methods: Water scrubbing, nitrogen purging, and caustic scrubbing — water scrubbing...
Key Highlights Two system types: Fixed detectors provide continuous area monitoring; portable detectors protect individual workers and support maintenance inspections. Sensor choice matters: Electrochemical sensors offer the best low-level sensitivity (0-500 ppm);...
Key Highlights Concentration-matched PPE: Respiratory protection must be escalated from half-face APR to full-face APR to SCBA as ammonia concentration increases through 25, 50, and 300 ppm thresholds. Glove material matters: Butyl rubber outperforms neoprene and...
Key Highlights All pressure vessels storing ammonia above 1,000 litres in India require a valid PESO licence before commissioning. The PESO application involves pre-approval design review, fabrication inspection, hydrostatic testing, site inspection and final licence...
Key Highlights Compressor selection governs capital cost, energy consumption and plant reliability in ammonia liquefaction. Shell and tube and evaporative condensers each suit different climatic and throughput conditions. Storage vessel design must comply with IS...
Key Highlights Ammonia cylinders must undergo hydrostatic testing every five years under the Gas Cylinders Rules 2016 in India. Hydrostatic test pressure is 1.5 times the working pressure; cylinders failing expansion limits must be condemned. Valve inspection and...
Key Highlights Liquor ammonia is available in three primary grades in India: Commercial (20 to 26 percent), LR (25 to 30 percent) and AR (28 to 30 percent). AR grade meets Analytical Reagent specifications with strict limits on heavy metals, iron, chloride and...
Key Highlights SCR DeNOx systems require anhydrous ammonia at a minimum purity of 99.5 percent by weight conforming to IS 1588. The stoichiometric molar ratio of NH3 to NOx is 1:1; operating NSR is typically controlled between 0.95 and 1.05. Ammonia slip must be kept...
Key Highlights Refrigerant grade anhydrous ammonia (R-717) must meet a minimum purity of 99.98%, versus 99.5% for technical grade. Water content limits are typically 33 ppm for refrigerant grade versus up to 300 ppm for technical grade. Oil content and residue on...
