MUÑA PUMPING STATION
It consists of three pumping stations, Muña I, Muña II and Muña III located on the banks of the Bogotá River. The objective of the stations is to raise the volumes of water from the Bogotá River in the Alicachín ponds towards the Muña reservoir in order to have a reliable flow of water for the operation.
MEASUREMENT OF HYDROGEN SULFIDE EMISSION, APPLYING THE METHODS OF ANALYTICAL AND SENSORIAL EVALUATION
The following table shows the values found for the measured emission factors in the two most important points, Alicachin Floodgates and Reservoir discharge (see figure 2,3 and 4 of Annex 1)
H2S at Exhibithion time of 1 hour
||H2S at Exhibithion time of 24 hours|
Limit (30 ug/m3)
Limit (7 ug/m3)
It is observed that the highest emission point was "Alcachin floodgate", it is at this point, where greater turbulence of the waters is generated when allowing the opening of the floodgates, suddenly increasing the speed of the water at this point, that promotes a greater volatilization of the compounds that form the odorous substances.
According to the Environmental Management Plan of the plant, a odors measurement with quarterly periodicity is established, whose results must be presented in the respective environmental compliance reports on an annual basis.
Enel Green Power is looking for solutions that can be applied to existing facilities to control the emissions of offensive odors and, possibly, evaluating their effectiveness through an exercise of on-site application and direct measurement. These solutions could be, for example, chemical substances.
Any proposed solution should address the following Solution Requirements:
1. The proposed solution should demonstrate quantitatively compliance with the parameters shown below, by means of a real application exercise on site and its direct measurement (before and after its application).
