Pakistan – SITARA CHEMICAL Industrial Nitrogen Generation System Project – Customer Case Study

SITARA CHEMICAL INDUSTRIES LIMITED is a renowned local chemical enterprise in Pakistan that requires a stable and reliable on-site nitrogen supply for its chemical production processes – including process protection and inerting operations. To replace its aging gas supply system, SITARA plans to procure a complete nitrogen generation system. Following multiple rounds of technical comparison and supplier screening, the company has ultimately selected Guangzhou Huilin Air Separation Equipment Co., Ltd. as its equipment supplier to purchase the WGSTD15098 complete nitrogen generation unit, thereby meeting its industrial-scale nitrogen supply requirements.

Huilin Company provides complete sets of nitrogen generation equipment, including the nitrogen generation unit, supporting air compressors, all standard accessories, and critical spare parts; the equipment is delivered as a complete set, enabling rapid installation and commissioning upon arrival at the port.

Before shipment, the entire system undergoes a 72-hour integrated commissioning test, during which purity, pressure, and control systems are calibrated item by item; an English-language operating manual and a spare parts list are also provided for use by on-site engineers in Pakistan.

The equipment was delivered to the Karachi Port, cleared customs, and then transported to the Faisalabad manufacturing facility for installation and commissioning, after which it was officially put into operation.

1. Stable and reliable gas supply: The PSA nitrogen generation unit enables continuous on-site nitrogen production, replacing traditional bottled nitrogen and eliminating the downtime risks associated with frequent cylinder replacement; it is designed for 24/7 continuous operation in chemical plants, meeting the gas supply requirements for inerting processes in chemical manufacturing applications.
2. Reduce overall gas usage costs: The equipment generates nitrogen on-site, eliminating the need for external nitrogen procurement and significantly lowering long-term gas purchasing and logistics costs for enterprises; the equipment employs an energy-efficient PSA process, delivering outstanding unit energy efficiency, which aligns with the factory's cost reduction objectives;
3. Adapted to local maintenance and operational conditions: The complete set includes ample standard accessories and core wear parts, reducing the procurement lead time for overseas spare parts; the English documentation is clear and easy to understand, enabling local technicians to independently perform routine inspections and basic maintenance;
4. 
   

Guangzhou Huilin provides a one-stop solution for the entire export process of complete sets of overseas equipment – ranging from preliminary technical design and L/C document matching to full-container cross-border sea freight delivery, factory testing, and the export of comprehensive foreign-language technical documentation. This solution addresses the challenge of ensuring a stable industrial nitrogen supply for SITARA CHEMICAL, thereby guaranteeing the continuous operation of chemical production processes while optimizing long-term nitrogen usage costs.
