The wastewater treatment facility for the Tarim Ethane-to-Ethylene Project, constructed by Hanqi Environment, commenced operations in June 2021 and passed final acceptance in December 2021. It has now maintained stable operation for over three years. Throughout this period, Hanqi has remained a dedicated technical partner, maintaining close communication and collaboration with the client.

In October 2023, Hanqi responded promptly to the client’s request for chemical dosing optimization to reduce energy consumption and operational costs. Our R&D team was immediately dispatched to the site, where they:

1. Conducted in-depth analysis of operational conditions and water quality

2. Performed systematic experiments

3. Optimized operational parameters and chemical formulations

Results Achieved:

• Sodium carbonate dosage reduced to 20% of original levels

• Significant decrease in sludge production

• Effective control of per-ton-water operational costs

• Ensured stable performance of treatment units

During the recent critical maintenance window at PetroChina’s Tarim Ethane-to-Ethylene wastewater treatment plant, Hanqi again dispatched a team to collaborate with the client on:
• Process parameter refinement
• Chemical formula optimization
• Dosing calibration
This ensures high-efficiency stable operation post-maintenance.

Corporate Commitment:
Guided by our long-term operational philosophy, Hanqi:
✓ Maintains strategic alignment with clients
✓ Focuses on full lifecycle management of wastewater facilities
✓ Achieves technological breakthroughs through continuous innovation
✓ Builds enduring client relationships based on professional trust and deep collaboration

These principles establish a robust foundation for sustained partnership and industry advancement.
