Cooling Tower and Water Boiler Lay-up

In this day of modern technology most cooling towers are laid up dry. Towers and/or boilers are drained out to avoid water freezing in the system. Big and small water treatment companies usually treat cooling water, for a cooling tower, through out the year. When it comes to seasonal lay-up, most conventional methods do not provide the advantages of VCI Corrosion Protection.

Corrosion Prevention Problem:

Conventional seasonal lay-up programs often use an oil-based product that does not apply evenly; they can cause significant gunk balls in the equipment and these products poses a tough challenge of disposal. This practice is environmentally unsound. Another problem with using oil-based products is that they may react with polymers in the system and with other materials. Oil-based products van be a source of nutrients for various kinds of bacteria, including anaerobic bacteria. This leads to promoting microbiological growth in the water system and hence bacterial corrosion.

The major shortcoming of conventional lay-up products is that they are strictly contact corrosion inhibitors (CCI*). A Contact Corrosion Inhibitor protects only the parts of the system that comes into direct contact. The overhead spaces, crevices and other such hard to reach spaces without having direct contact with the CCI ends up unprotected. These parts of the system tend to corrode during the down time because they lack lack corrosion and rust protection. Due to all of the above reasons it becomes important that a thorough cleaning of the system, using additional chemicals, is scheduled before commissioning the water system back into production.

Solution:

A systematic and easy approach to lay-up of water systems during down time utilizing an environmentally safe, inexpensive and easy to apply VCI Corrosion Protection that is typically superior to conventional methods of oil-based products in water systems. These products will eliminate the use of hazardous chemicals for this process.

VCI Powders & VCI LIQUIDS are two products that contain VCI. (Vapor Corrosion Inhibitor)

VCI powders can be applied by 'dry fog' and they are also water-soluble materials perfect for seasonal or long-term lay-ups. VCI consist of blend of compounds that volatilize and create a VCI environment in the system. VCIs are adsorbed onto the metal surfaces forming a monomolecular layer. These protect both the anode and cathode sites of the metal surface.

VCI Liquids are added to water and applied by circulating, spray or 'wet fogging'.

Compared to conventional corrosion inhibitors, additionally provide:

Vapor Phase Corrosion Inhibitors VCIs protect metals both in the in liquid contact state* AND in the vapor state* AND the interface of water and vapor, to protect surfaces in contact with air.

*CCIs = Contact Corrosion Inhibitors require direct contact with metal to be effective

*STATE = The physical state of the water molecule. i.e.. Solid, Liquid or Gas

A systematic VCI approach enables VCIs to protect even small crevices from corrosion. Our VCI water system productss are multi-metal formulations that protect various metals including galvanized steel.

Method of application:

Dry Lay-up:

Apply VCI powder by sprinkle, dry fog in tower and close all external openings to begin corrosion protection.

Flushing Lay-up:

Apply VCI liquid or powder into cooling water and re-circulate the water for 6 hours. Drain the treated water and lay-up the tower.

Wet Lay-up:

Apply the appropriate amount of VCI powder to the cooling water and re-circulate the water for about 6 hours. Leave the tower with the treated water inside.

Summary:

VCI Corrosion Protection Products Provide:

Biodegradable, and environmentally friendly. Does not contain nitrites, phosphates, chromates, and heavy metals.
Economical (100% effective) way of protecting cooling towers during seasonal lay-up periods.
Saves money and labor by eliminating the use of expensive cleaning chemicals while effectively protecting the cooling water system against corrosion.
Protects in vapor, liquid, and interface states by incorporating proprietary VCI technology.
Readily water-soluble.

There are many opportunities to improve cooling tower system efficiency through the use of chemical treatments. Protecting a cooling tower properly during a lay-up period is an important aspect of cooling tower operation. It can improve efficiency of the system during the operation and save the maintenance engineer lot of time and money if done right.
