Industry Application

Yangzi Petrochemical: For the deethanizer reboiler and depropanizer reboiler in the gas fractionation unit, the original tube bundles were replaced with high-flux porous tube reboilers. This design reduced the heat transfer area, doubled the heat transfer coefficient, significantly reduced steam consumption, and achieved investment payback within half a year.

Zhejiang Refining & Chemical Ethylene Retrofit
Application: High-flux tube heat exchangers applied to depropanizer and deethanizer reboilers.
Data: Heat transfer coefficient of 6500∼7200 W/(㎡·℃).
Results: Single unit heat transfer area reduced by 50%, and plant energy consumption decreased by 8%.

Hengli Petrochemical 20 Million Tons/Year Refining & Chemical Integration Project (Ethylene / PDH Plant)
Application: Depropanizer reboilers, propylene/propane separation tower reboilers
Breakthrough: Domestic high-flux tubes replace imported UOP tubes from the US
Results: Equipment investment reduced by 35%, delivery cycle shortened from 12 months to 6 months
