CASE STUDY

Waste Heat Recovery 25% Steam Reduction

Recover wasted heat from paper mill white water and turn it into real energy savings with a high-efficiency plate heat exchanger system.

25% Steam Saving
Payback < 1.5 Years
Anti-Clogging

Project Overview

A paper mill in Pakistan generates large volumes of high-temperature white water (50–70°C) during production.

  • Waste heat was directly discharged
  • Steam consumption remained high
  • Energy efficiency was low

Our Solution

We designed a complete white water heat recovery system using high-efficiency plate heat exchangers, optimizing the entire process instead of just supplying equipment.

  • Recover heat from white water
  • Reuse energy back into production
  • Reduce steam consumption significantly

Equipment Configuration

  • Plate Heat Exchangers: 2 units
  • Capacity: 150 m³/h per unit
  • Material: SS304 / SS316L
  • Heat Transfer Area: ~200 m²
  • Temperature: 65°C → 35°C

Key Advantages

  • Anti-Clogging Design: Wide-gap plates prevent fiber blockage
  • High Efficiency: Maximized heat recovery
  • Easy Maintenance: Removable structure
  • Robust Design: Suitable for complex fluids
