Removal, transport, treatment and final disposal of refinery sewage sludge in Colombia

摘要

The project was undertaken at the Ecopetrol Refinery at Barrancabermeja, Colombia (Figure 1). The separating unit, in addition to receiving stormwater waste from the industrial area, also converges as "fresh" catalysts of the UOPI cracking unit. According to reports from the refinery operation, this presents problems in the loading process of the hoppers, as well as sludge of the U-2900 water plants, by dragging or disposing of the process units to the rainwater systems. The volume to be pumped was 787,517 cubic feet (22,300 m~3), and it took a total of 191 pumping hours. In the end there were 3,000 tons (2,721 tonnes) of dewatered sludge: 1. Percent dewatered solids: 50% 2. SST effluent: 80 PPM.
