Daqing Oilfield
Scaling in the heating furnace's circulating water system degrades heat transfer in the tubes and increases fuel consumption.
Issue
Situation before processing
High hardness in the circulating water of oilfield heating furnaces causes scaling on tubes and heat exchange surfaces, reducing heat transfer efficiency and increasing fuel consumption and maintenance costs.
Instructions
Installation Location & Plan
Install equipment downstream of the circulation pump on the main water supply line, matching coil groups to flow rates to cover both the furnace and tracing systems.
Acceptance and Operational Performance
Significantly reduced scale buildup rate in furnace tubes, with flue gas temperature and fuel consumption stabilizing; fewer shutdowns for cleaning.
Note: Project outcomes depend on water quality, operating conditions, and management practices. This case study illustrates the approach for similar systems only and does not constitute a guarantee of results for specific projects.
