Substance of development
Economical absorption-catalytic technology of nitrogen-hydrogen protective atmosphere production is proposed. At the heart of technology are used such processes:
- autothermal air catalytic natural gas conversion in shaft reactor;
- clear nitrogen-hydrogen mixture gassing by Pressure shift absorption (PSA) method;
- dilution (of necessity) of finished product by pure nitrogen (or exhaust nitrogen of metallurgical enterprises, cleaned combustion products of industrial enterprises).
Protection atmosphere utilization:
- nonoxidation heating for hardening;
- bright annealing of nonferrous steels;
- ammonia synthesis etc.
Project cost depending on productivity and final product quality – from 40 $thousands up to 300 $thousands. Pay-back period up to 2 years.
