(663d) Technical Aspects More Important to Increase in Concentration Cycles of Cooling Towers

Since January of the 2006 began the treatment in cooling towers with high concentration cycles silica base (4.0) on the Petrochemical Independence Complex (CPI) to save water and to improve excess of equipment or to make it more profitable into PEMEX subsidiary as well as to satisfy the necessity of electrical energy the same sector.

Before 2006 to cover the needs of CPI it had working only one turbo generator with 7 Megawatts of capacity. Actually are working two turbo generators with 30 Mw each one of capacity maxim.

The consumption of water to 2 cycles of concentration silica base was of 4000 m3/d, today to 4 cycles is of 2800 m3/d arising a saving of the 30 % of water consumption and a capacity of 50 Mw of energy delivered.

Although the saving has to been economic substantially and satisfactory environmentally speaking, some operational problems we have been had that's why the present work shows the more important technical considerations that we will be to make to avoid precipitation problems of present inorganic salts.

First, we show the treatment during the increase to 4 concentration cycles silica base, physic-chemical results obtained in make up water, return and supply.

Later the deviations founded during the treatment that were analyzed taking into account the theoretical information of similar behaviors.

Finally we shown the technical recommendations more important to carry out efficiently a water saving without problems during treatment to high concentration cycles silica base.
