Amine treatment (amine wash) in large power plants with LEWA pumps and systems

The goal of amine treatment and amine wash is to extract over 5 million tons of CO2 per year by means of other catalysts from exhaust gases occurring in typical power plants of today.

For this exhaust gas treatment in most large fossil fuel power plants, LEWA pumps are used for metering additives, such as caustic soda.

Solution

Operationally reliable, nearly maintenance-free LEWA metering pumps are actually replacing the centrifugal pumps conventionally used in the power plant sector.

Advantages of LEWA pumps:

  • Hermetically tight construction (conforms to Technical Instructions - IVV Directive 96/61/EG)
  • Compact design
  • Robust and reliable
  • Long service life of wear parts, such as sandwich diaphragms and fluid valves
  • Low-maintenance diaphragm pump technology
  • Ex-proof in compliance with ATEX
  • Meets power plant standards

LEWA also supplies complete metering systems for amine treatment. Pipelines, external safety valves, etc. are selected to customer-specific plant regulations.

Areas of application

Amine treatment for gas cleaning and flue gas desulfurization:

  • Coal-fired power plants
  • Natural gas power plants
  • Power plants in refineries
  • Power plants in petrochemical plants
  • Waste incineration power plants
