Puyang Lianzhong Xingye Chemical Company Nitrogen Generation Support Project

Industry: Fine chemicals; production of new materials from C4 and C5 series.

Previous gas supply model: The existing nitrogen generator suffered from rapid molecular sieve degradation, a short service life, high maintenance costs and unstable operation, which affected the continuous production of chemical plants.

Equipment procured: 350 Nm³/h PSA nitrogen generation system with 99.9% purity.

Technical advantages: High-performance molecular sieves combined with an optimised adsorption process ensure a long service life; purity has remained stable for four years since commissioning without the need to replace the molecular sieves. Fully automated, continuous gas production via PLC controls meets the requirements for nitrogen purging of storage tanks, reactor inerting and pipeline flushing. On-site gas generation isolates oxygen, mitigating the risk of explosions and deflagration, whilst significantly reducing annual expenditure on molecular sieve maintenance and minimising downtime for repairs. The system is suited to the chemical industry’s 24-hour continuous production, helping enterprises to reduce costs and improve efficiency.
