Welcome to our site!

 

On our site You can find out all about what is Hydro-X process and what it is used for, as well as the methods to be implemented during the Hydro-X process ( conditioning boiler water, scale and corrosion removal, as well as preventing them, etc.)

 
 
 

THE FUNCTIONAL PRINCIPLES OF HYDRO-X PROCESS

 

THE DISSOLUTION OF EXISTING BOILER SCALE BY APPLICATION OF HYDRO-X

Without production stoppage

The Hydro-X process makes the total removal of old scale layers from boiler and economizer possible without breaking-off usual production hours.

Dissolution of the scale layer

Hydro-X contains particles derived from lignin. The lignin molecules expand in step with increasing temperatures. When the lignin particles permeate into the pores of the boiler scale they expand and loosen the scale formations from the metal. The loosening of the scale formations occurs in several stages and is strongest at the heating surface with the highest temperatures. The effect is immediately visible on opening the boiler after the first period of the Hydro-X treatment. The optimal removal of very hard and thick layers of scale in economical terms may best be done by shutting down the boiler, opening and chemical cleaning, thereby reducing the consumption of Hydro-X to a minimum.

The transformation of scale into sludge

The boiler scale decomposes into loosened and fine-grained particles. If the scale remains in the boiler it will eventually transform into a free-flowing sludge, easily removable by blow-down. At this stage as well, the Hydro-X process follows principles which differ from older methods for the removal of old scale by chemical solution.

 

STEAM CLEANING BY THE HYDRO-X PROCESS

Hydro-X for all steam plants

Regardless of steam application purposes the boiler water of the steam plant may be conditioned by the Hydro-X process. The physico-chemical boiler water treatment ensures not only optimal operational utilization of the plant but also 100 % pure steam production.

100 % pure steam for every purpose

The steam is directly applicable for any purpose, for instance. For autoclaving in hospitals, the food processing industry and export authorized meat production.

Low chemical addition

Hydro-X makes the addition of the normally large quantities of sludge producing chemicals, such as carbonates or phosphates, unnecessary, thereby reducing the total quantity of sludge to a minimum and furthermore eliminating the risk of foaming due to too high an alkalinity.

No priming whatever plant type

Priming due to the chemical composition of the boiler water is prevented by the Hydro-X process. Priming is especially marked with certain pre-treatment plants and in this case the glycol derivatives of Hydro-X will effectively eliminate the risk of priming.

 

The glycolic derivatives adsorb on both sides of the floating boundary surface to the steam bubble. They furthermore drain off the water, leading to the burst of the steam bubbles.

Optimal sludge deposit

Both dissolved solid and the gaseous impurities are adsorbed and neutralized. The deposit occurs as an amorphous and very mobile sludge. The removal of this sludge simply happens through blow-down. The consistency of the sludge prevents impurities from entering into the steam and going off with it. The steam and going off with it. The steam is therefore completely neutral and pure. The pH-value is 7.0. The Hydro-X process neutralizes and adsorbs all impurities previously contained in the steam.

Rapid effect

Only a few hours after adding the Hydro-X start dose, the effect is already visible. The characteristic cleaning has started and the steam is ready for application.

Protection of the entire plant

An effective protection of all parts of the plant in direct connection with the boiler is secured, such as superheater, turbine and condensate lines.
