Falling film evaporator train, pulp & paper industry

HPD has often led the industry by introducing new evaporator designs into successful commercial operation. In the 1980's, HPD led the movement in the pulp and paper industry by implementing falling film evaporation equipment as the standard in black liquor processing.

Evaporation technology from HPD has also been incorporated in innovative systems in several key industries such as SAGD oil produced water treatment and key components of environmentally-friendly applications such as zero liquid discharge (ZLD) facilities to minimize waste volume and reclaim valuable water resources.

HPD offers several technologies for evaporation that include:

  • Natural circulation
  • Rising film
  • Falling film
  • Forced circulation evaporators

Crystallization Solutions

ZLD crystallizer, chemical production

HPD crystallizers are used for premium chemical production processes

Crystallizers from HPD provide a robust and efficient means to produce premium chemicals, concentrate highly viscous process streams, and treat difficult waste streams to minimize overall volumes into manageable solids.

HPD's crystallization offering features these technologies:

  • HPD Growth™ crystallizer
  • PIC™ (draft tube baffle)
  • Enhanced Forced Circulation (turbulence enhancer)
  • Forced circulation crystallization
  • Falling film crystallizers

Integration of Additional System Components

HPD integrates other system elements to provide a complete system solution

System integration provides customers with a total project solution in both the design of a system and in project execution. The expertise and understanding of each element of a total system design allows HPD to fully optimize the entire process upstream and downstream of the evaporation and crystallization equipment. Each system is designed to fully integrate into the host facility with process, execution and performance guarantees.

The additional system components may include:

  • Mechanical Vapor Recompression (MVR) systems
  • Heat exchangers
  • Condensers
  • Strippers / distillation
  • Reboilers
  • Degassifiers
  • Solids handling equipment
  • Pre-treatment systems
  • Drying equipment
