Gaseous effluents from a chemical company contain traces of sulphur dioxide, that result in the effluents exceeding the environmental limits. Directing the effluents to a catalytic conversion tower allow for oxidation of sulphur dioxide to SO3, which can be directed to the production. Nevertheless, the hot air from the effluents will be utilized for the reaction.
Although the company monitors their overall loss of phosphorus pentoxide, lack of distribution of the loss at main leak points hinders the structured corrective actions. The company was recommended to practice the qualitative and quantitative monitoring of losses, following the structure of cost centers defined within the MFCA, so as to define the focus areas of option generation, and develop structured saving measures.
An aromatic production company has expanded overtime, with the water network being expanded to match with new installations. This expansion of water network was conducted in an “as needed” manner, ending up by having many connections and a complicated network with high losses. renovating the water network considering the energy efficient design shall save on water leaks, as well as energy demand.
Although this pharmaceutical company had capacitor banks installed at the transformer to correct the power factor, those banks were noted not to function properly as the power factor was highly fluctuating. Installation of an automatic regulator, together with the installation of two fixed batteries supported in maintaining the power factor, and thus increased the bonus on the bill.
The drying tower of a detergent production company is running at 50% of its capacity, due to unoptimised operating parameters. Reviewing the operating parameters, particularly the air speed, and running a detailed mass/energy balance on the tower can provide a productivity gain of 20%, saving on material, energy and water.
