Detection of H2O in molecular sieve dryers

Optimize plant efficiency, prevent damage, and reduce downtime in downstream cryogenic equipment

Detecting trace moisture in molecular sieve dryers is vital in natural gas, NGL and LNG production. Moisture damages downstream equipment, and if frozen, it can lead to 3-5 day production stops. Early detection of mol sieve bed breakthroughs and shortening the regeneration time of the mol sieve beds are top priorities. However, many H2O measurement technologies are maintenance intensive, slow to dry down and stabilize, and prone to contaminant interferences.

    with less maintenance, downtime, and regeneration costs

    Endress+Hauser’s TDLAS analyzer solution offers continuous, real-time moisture measurement with proven metrology that enables optimum dryer bed switching while optimizing energy consumption and molecular sieve life. Accurate H2O measurements that are immune to contaminant interferences prevent downstream asset damage. Our reliable analyzer measurements also decrease regeneration costs, reduce downtime and require minimal maintenance which lowers OPEX.
