Special deposition of refrigerant condenser with controlled corrosion
A condenser is a device that is responsible for cooling water and mainly converting steam into a liquid. Condensers are a type of heat exchanger in which hot steam is transferred to another fluid, such as air or water, and the steam becomes liquid. The conversion of steam into liquid into the condenser results in the deposition of solutes in water and also causes severe corrosion in the plant.
The major problems that occur in the condenser and cause high energy costs is the phenomenon of sedimentation on the heat transfer channels. The water used to cool the hard condenser is mainly due to cations such as calcium and magnesium.
In order to eliminate the precipitates formed in the condenser and increase the amount of heat exchange, the required amount of cold condenser solution (MDA106) is added to the water circulation system of this system. With this major method, the condenser sediments are destroyed. The use of cold mist solution is the cheapest, most effective and safe method in comparison to various physical and chemical dehydration methods (eg, acid washing).
The cold-melting solution of the condenser by dissolving the intermolecules of the sediments leads to the dissolution of the precipitate in water and prevents precipitation of carbonate and sulfate compounds due to the high electronegativity of the mixture.
After calculating the estimated amount of sediment in the condenser and its communication pipes with the refrigerating system, for each kilogram of estimated sediment, enter 2 liters of MDA0106 code solution, for 3 to 6 hours during the operation of the condenser pumps (non stopping system). Dissolve the condenser casings in the water, then remove the heavy water and then thoroughly clean; re-dewater the system and use MSA1062 (anti-fouling and special corrosion condenser) solution according to calibration and consumption.
It is recommended that the condenser be washed in 2 steps. Sampling of water before injection and heavy water output is required for documentation.
