ROP-Programmdesignd for ACR by the Technical University of Vienna • Fouling prediction • Determination of most economical exchangers maintenance • Calculation of charges in monetary value caused by tube efficiency losses Applicable for all industrial used tubular heat exchangers AC Rädler Environment technique GmbH, www.ac-raedler.at lecture: Sigrun Rädler
Fouling process is predicted immediately:Increased Temperature/EnergyGrowing of FoulingLoss of Capacityin days AC RädlerEnvironment technique GmbH, www.ac-raedler.at lecture: SigrunRädler
Feature for operation cost:Company own figures are put (in the masque) and are computed regarding cost of - energy - stand still - capacity loss AC Rädler Environment technique GmbH, www.ac-raedler.at lecture: Sigrun Rädler
Exchanger efficiency losses in Monetary ValueCleaning point Loss during operationCost ofmaintenance AC Rädler Environment technique GmbH, www.ac-raedler.at lecture: Sigrun Rädler
Improved productivity save resources and cost1) Legend: Last slide indicates the source of following outcome • Efficient exchanger operation is the simplest way to reduce production costs • Chemical cleaning cause rough inner tube surface which lead to faster fouling, to earlier corrosion and tube replacement • Smooth inner tube surface prolong optimal exchanger operation • Regular cleaning diminish corrosion failure AC Rädler Environment technique GmbH, www.ac-raedler.at lecture: Sigrun Rädler
Regaining of blocked tubes improve exchangers operation capacity – with RTC possible to regain • Regaining of fully exchangers efficiency contributes to energy saving, capacity improvement and at least to improve exchangers life cycle. • Optimal exchanger operation further contributes to: • less pump pressure • less repairs • less problems before or end of pipe equipment • reduction of emissions AC Rädler Environment technique GmbH, www.ac-raedler.at lecture: Sigrun Rädler
Optimal maintained heat exchangers may avoid to much oversized exchanger design • Oversized exchangers capacity vary from 10 % to 300 % • 25 % of oversized exchanger design will increase investment cost up to 12 % • Parallel connected exchangers, which are optimal maintained: • Minimise efficiency loss • Minimise production loss (no stand still) • Reduce corrosion failure • Contribute to plant harmonization, • improve production quality • anddouble exchangers life cycle AC Rädler Environment technique GmbH, www.ac-raedler.at lecture: Sigrun Rädler
