Fushun Petrochemical Divn of PetroChina
Detergent Chemical Plant
Armstrong International designed, engineered, installed and financed a steam system and condensate recovery system optimization project for the Detergent Chemical Plant, Fushun Petrochemical Division of PetroChina.
This is one of the several sub-projects covered in a system optimization agreement under the cooperation of Fushun Petrochemical and Armstrong.
Scope of Work:
Optimize condensate collection stations for tracing lines
Merge, terminate or re-route the existing condensate return lines; change overhead pipelines and buried pipelines to overhead pipelines
Re-design the flash steam utilization system
Install condensate treatment to system (IEF) to remove oil, iron, silicon and floating matters from the condensate before being pumped to the demineralized water tank
Apply steam traps in tracing lines that resist back pressure and reduce steam carry-over
The annual condensate recovery: 103,000 tons; steam saving rate: 30%; annual steam savings: 43,000 tons; net energy savings: $434,000; payback period: 2.5 years
- Pipelines enjoy little heat loss, even resistance distribution, high reliability and easy maintenance
- Condensate heat is recovered to its utmost. No steam is discharged directly to the atmosphere
- Condensate treatment integrates filtering with ion exchange. With a fully developed monitoring system, PLC control system and two industrial PC work stations, the system is automatic and carefree.
- After treatment, the condensate can fully comply with the quality requirements for MP boiler feed water
