  1. Alfa Laval Group Presentation

  2. Alfa Laval is a leading global provider of specialized products andengineered solutions. The company

  3. Activities We help customers to heat, cool, separate and transport products such as oil, water, chemicals, beverages, foodstuff, starch and pharmaceuticals.

  4. We serve most industries Beverage Biochemical Brewery Chemical Engineering Fish and meat processing Food processing Heating and ventilation Marine Mining Oil and gas Pharmaceutical Power generation Refrigeration Steelworks Starch Sugar Vegetable oil Water and waste watertreatment

  5. A global company • 20 Production units* • 70 Service centres • Sales companies in 50 countries • Other sales representation in 45 countries * Plus a number of minor production and assembling units

  6. Gustaf de Laval (1845-1913) “The Man of High Speeds” • 200 projects and inventions • 92 patents, including the milk separator (1878) and the steam turbine (1883) • Started 37 companies

  7. Key technologies Heat Transfer Energy saving solutions for heating, cooling, ventilation, evaporation and condensation Products • Plate heat exchangers • Purpose built systems • Tubular heat exchangers

  8. Key technologies Separation Efficient separation of liquids from liquids, of particles from liquids and of fluids and solids from gases Centrifugal separation products • Disc stack centrifuges • Decanter centrifuges Filtration products • Membranes • Filters and strainers

  9. Key technologies Fluid handling Safe transport and control of fluids Products • Pumps • Valves • Tank equipment • Installation material

  10. Focus on R&D 18m / 59.06ft • Constant improvements of existing products • New capacities, materials and functions • New products and technologies • Cooperation with customers and partners The giant Alfa Laval Packinox welded plate heat exchanger The T50 plate heat exchanger for super-sized plants The X20 high-speed separator for heavy crude oil dehydration System for cross-flow filtration of beer

  11. A ski slope in Dubai’s desert climate has become a reality. Alfa Laval has supplied glycol coolers which maintain Ski Dubai’s natural snow at the right consistency. Focus on customer segments Marine & Diesel Comfort & Refrigeration Queen Mary 2, the world’s largest ocean liner, has equipment from Alfa Laval to clean oil and oily water and to produce fresh water.

  12. Thermodynamics

  13. Thermal balance T1, in T2, out Q-given= Q-taken Q-given= m1 . cp1 . (T1 - T2) Q-taken = m2 . cp2 . (T4 - T3) T1, out T2, in Surface Q = capacity [W] m = massflow [kg/s] cp = specific heat [J/kg°C] given taken

  14.  1  2 • Q = capacity (W) • k = heat transfer coëfficient (W/m²°C) • A = heat transfer surface (m²) • LMTD = Logaritmic Mean Temperature Difference Q= k . A . LMTD

  15. Heat Exchangers
