Combined Heat and Power

Over time, inevitable fouling erodes and corrodes delicate equipment while also interrupting airflow through the gas turbine compressor. This reduces efficiency; increases the risk of unscheduled shutdowns; and can cost you millions of pounds in losses over a year.

Investing in cleaning equipment and running regular washes is an extremely cost-effective way of maintaining your equipment, regaining lost power, and boosting your bottom line.

Yes! By running a cleaner gas turbine compressor your plant will burn fuel more efficiently and give off fewer emissions. Our unique FYREWASH® range of chemicals also includes specially designed detergents for environmentally sensitive sites. We can help you choose the ideal combination of equipment and detergents to minimise your environmental impact while boosting efficiency and power.

Different types of contaminants cause different issues but any impurities in your system are potentially dangerous and costly. Unfortunately, some fouling is inevitable and common foulants include:

• Oil from lube systems
• Glycol from antifreeze
• Salts: carbonate salts, sulphide salts, iron salts, sea salt
• Hydrocarbons
• Sand

On-line cleaning is gas turbine compressor washing during normal operation. Using a Rochem online cleaning system, water and detergent is injected directly into the compressor, dislodging, dissolving and flushing away foulants.

This type of gas turbine cleaning involves shutting down the compressor and manually cleaning it. Although thorough, this method is disruptive, labour-intensive and time consuming.

We recommend a combination of both cleaning methods: regular on-line washes with the occasional off-line clean. You can find out more about the difference between online and offline cleaning here.

Although many foulants will be washed away with pure water, a specialised detergent will ensure a reliable, thorough clean. Our range of FYREWASH® chemicals are designed exclusively for cleaning gas turbine compressors and include products for a range of environments. We can help you choose the right product for your site.

Rochem gas turbine compressor cleaning equipment can be retrofitted in most cases. It safely delivers a precise amount of cleaning chemicals directly into the compressor during normal operation. Your bespoke proposal will outline specific requirements but you'll need:

• Injection nozzle system
• Rochem wash skid: a self-contained skid that operates at pressures up to 100 barg.

Rochem equipment can be retrofitted in most cases and we can manufacture parts for any application. Standard nozzles use NPT or 1-1/2" ANSI/DIN flange connections rated to suit the process application.

Rochem equipment and FYREWASH® chemicals have been used at countless sites around the world for decades without reported incidents. Properly cleaning your gas turbine compressor actually reduces the risk of failures and shutdowns.

Rochem products and cleaning are very unlikely to damage any part of your turbine. For total peace of mind, we always carry out a design verification at every site.

The initial cost of equipment and minimal ongoing expense of detergent is recouped several times over in increased power output and decreased unscheduled shutdowns. That's before you also consider the other benefits including reduced greenhouse gas emissions.
