摘要
Supercritical water oxidation (SCWO) is a new and promising technology for treating organic waste and recovering energy. High energy consumption is a major problem preventing its commercial application. Energy recovery is the most effective method for reducing energy consumption of an SCWO system. To maximize the energy recovery of the SCWO pilot plant with a transpiring wall reactor, the reactor effluent is used to preheat both feed and transpiring water and produce hot water. An experimental study was conducted to investigate the influence of the operating parameters on energy consumption per unit total organic carbon (TOC) removal (ECPT) for saving the energy of the system. Results show that the effect of feed concentration on ECPT is the most significant and that of high feed concentrations, result in lower ECPT. Lower ECPT is also present at high feed flow rates, but at the expense of the decrease of TOC removal efficiency when the feed flow rate exceeds 14kg/h.
