Abstract
Disclosed is a soapstock treatment apparatus which can treat a soapstock produced during a plant oil production process within a short period and with a high degree of efficiency. As shown in FIG. 1, the soapstock treatment apparatus includes a reactor 20 configured to oxidatively decompose a soapstock, an electric heating coil 23 configured to heat water in the reactor 20 at 650° C. which is not less than the critical temperature of water, a high-pressure pump 13 configured to pressurize the water in the reactor 20 at 17 Mpa which is less than the critical pressure of water, and a compressor 33 configured to pressurize the water in the reactor 20 at 17 Mpa which is less than the critical pressure of water. Also, an exhaust pipe 41 for discharging a reaction gas generated by the oxidative decomposition treatment and a waste pipe 51 for discharging a solid (inorganic) residue generated by the oxidative decomposition treatment are connected to the reactor 20. Furthermore, a gas-liquid separator 44 for separating the reaction gas into a gas substance and a liquid substance are connected.
