Petroleum sludge has attracted wide attention owing to its large quantity, hazardous character, and difficulty in processing. Furthermore, petroleum sludge contains a high proportion of hydrocarbons which are valuable for recovery. In this paper, the possibility of producing hydrogen-enriched syngas from different petroleum sludge by a two-stage catalytic pyrolysis under different temperature has...
Increasing depletion of conventional oil resources has driven interest in recovery of oil resources from petroleum sludge. To improve the quality of recovered oil, it is essential to maximize the removal of emulsified water, dissolved salts, and other impurities. Therefore, this study was conducted to characterize the emulsified water droplets and salt in petroleum sludge through differential scanning...
An efficient model is proposed for predicting the behavior of solid particles in petroleum sludge during centrifugation, from the particle size distribution and petroleum viscosity. Petroleum sewage sludge (PSS) and oil-tank bottom sludge (OBS), respectively collected from a sewage reservoir containing petroleum waste water and a petroleum oil storage tank, were studied. The solid particle removal...
