ZNH hydropurification

1、 How it works

Low purity ammonia and entrained gas enter the proportioning mixer at the same time, and then enter the stripper. Under the action of deoxidation catalyst, oxygen in pure ammonia reacts with hydrogen to generate water. The chemical equation is: 2hx + 0, + 2h-0 + 0, and the residual hydrogen is deeply removed; the water is cooled by the cooler, and then enters the dryer for deep dehydration and dust removal to obtain high-purity nitrogen

2、 Technical features

It has the advantages of simple operation, convenient maintenance and stable performance; integrated skid structure design, easy installation and use, and small land occupation; advanced hydrogenation ratio technology, high control precision, safety and reliability, unqualified nitrogen venting device to ensure the quality of finished nitrogen; high quality and high efficiency catalyst, deoxidation at room temperature, no activation, energy consumption is greatly reduced; it can be linked with PSA nitrogen production device, and has many advantages It can be equipped with automatic chlorine dosing ratio function, high control accuracy, safety and reliability.
