POTENTIAL FOR THE DEVELOPMENT OF RESIDUAL LIQUIDS PRODUCTION ACETYLENE

Abstract

The goal of this paper was the evaluation of the material and energetic potentialities of liquid wastes in acetylene production, and their environmental and energetic implications; with that
purpose a liquid waste characterization was done in an acetylene plant. There were determined the influence of such variables as: production volumes, treatment efficiencies, and whitewash use, in the pollution loads of significant parameters which in 2008 amounted the following values: 265 T of total solids, 1680 m3 of sedimentable solids, 3,7 T of Calcium, and 4,2 T of COD. Although the liquid wastes of the process are partially used as paint, there remain wide potentialities that would generate important economic revenues. The thermodynamic evaluation of liquid wastes has shown
that for each cubic meter of acetylene there are generated 5580 kJ of energy. It is concluded that liquid wastes in acetylene production can be materially and energetically used, decreasing the negative environmental impact of their disposal into the environment.
