Chemical Cleaning

Chemical Cleaning

Our process can be applied both online and offline. With the longest experience in the industry, we are specialized in the chemical cleaning of water cooled generator coils and the stator cooling water system. Our method is based on the use of chelants (e.g. EDTA) with innovative developments built on 40 years of industry knowhow.
Chelant cleaning removes copper oxides without attacking the system materials. The method employs dedicated monitoring of the process parameters, customized addition of the chelating agent and an oxidizer, and proprietary auxiliary chemicals.

We are currently the only company capable of deploying experienced teams to safely conduct online chemical cleanings while the machine is in operation (More details here).

Key facts and competences

  • Online: cleaning is done while the generator is running; the cleaning does not interfere with any regime of generator operation
  • Offline: cleaning is done while the generator is shut down, usually during outages. This means reduced cleaning time, reduced costs
  • Emergency cleaning: fast and professional support from the beginning to end to prevent forced outages
  • Preventive maintenance: Copper oxides are formed naturally, and might cause a forced outage. Well planned preventive maintenance will keep the unit running and the cleaning also helps assess the unit condition
  • Restoring a stable oxide layer: In some cases, an instable oxide layer can cause problems. We can replace it with an optimally-formed and stable layer.
  • Targeted single bar treatment: In cases of severe plugging, an approach combining mechanical with targeted chemical cleaning is usually successful.

No plant interference: our equipment is set up at the cooling water skid, usually located in the basement and out of the way
No environmental impact: zero liquid waste
Root cause analysis: Before, during and after a cleaning, SvoBaTech is supporting you in researching the root cause for the plugging

Alkalization

Alkalization

In some situations it can be beneficial to run a stator cooling water system with alkaline chemistry. An analysis of the situation is necessary to assess whether this measure is useful or not.
After working with and analyzing all popular designs in the industry, we designed a low-maintenance, failsafe and modular system to satisfy all needs. It can be installed and commissioned while the plant is operating.

What you get

  • Recommendations on
    • Benefit of alkalization
    • Best configuration
  • Delivery of complete modular skids
    • Easy to install during operation with standardized interfaces
    • Easy integration in all stator cooling water systems
    • Controls pH reliably with a tolerance of +/- 0.05 units
    • Low and simple maintenance
  • Several independent safeguards against over-injection
  • Extra low maintenance option available
  • Stand-alone island solution available

Instrumentation

Instrumentation

The generator requires relatively low maintenance compared to other components, such as the turbine or boiler. As a consequence, stator cooling water systems are an often overlooked part of auxiliary systems.
Consequently, instrumentation can be in sub-optimal condition.This can allow for dangerous situations to develop without warning.
Keeping your instrumentation updated does not cost much, and pays back by avoiding downtime and failures and helps to keep that system running another twenty years without trouble!

What you get

  • Analysis of existing instrumentation
  • Recommendations on
    • Minimal requirements
    • Recommended requirements
    • Safe requirements
  • Delivery of complete modular skids
    • Instruments from reliable manufacturers, but customer wishes can be met
    • Easy to connect with standardized interfaces
    • Easy integration in existing monitoring system
    • Easily expandable – buy the minimum now, be ready to expand later
    • Includes sampling point that satisfies best practice considerations for grab samples
  • Interpretation of data by our experts available
