Recently, an application of our proprietary technology, the Whirl Wet Dust Collector, remarkably contributed in reducing CO2 emission whereas solving a considerable issue of Particulate Matter in a Fertilizer industry.
Our Customer used to apply a mature technology, the Venturi-Separator, in order to effectively abate a huge amount of dust resulting from a process of production of fertilizers based upon strong acidic attack on phosphorite sands.
The Venturi-separator is effective enough but is very much energy consuming since, to achieve satisfactory abatements matching the current regulations in terms of PM, must generate very high pressure drops within its throat which, obviously are translated into high power needs at the ID Fan.
The former figure in terms of power, considerably high, being in the range of more than 1.3 MWh, was necessary in order to match the limit of 20 mg/Nm3 at the stack for the species PM. The 3 installed Venturi-separators were doing their job but the price, in terms of power consumption, was inacceptable.
3 Whirl Wet units, may do the same job, but the power consumption is dramatically reduced to almost 1/3 of the Venturi, being in the range of 500 kWh.
Such reduction reverberates not only on the operational costs with a saving of around 500,000 euro/year (average cost of the kWh approx. 0.08 euro) but also on the CO2 emissions
In fact, the production of 1 kWh, nowadays, generates 238 gr of CO2.
Considering 8,500 hours of continuous operation, to pass from 1.3 MW to 0.5 MW means to save more than 1,600,000 kg/year of CO2.
Whirl Wet isn’t just an effective dust collector: it is also an energy saver and an implicit CO2 catcher. Good news then, about environment.
