The hydrogenation liquid in the hydrogenation liquid storage tank enters the hydrogenation liquid pump together with the phosphoric acid aqueous solution from the phosphoric acid storage tank. With the help of the hydrogenation liquid pump, the filter further filters the solid impurities in the hydrogenation liquid pump and then enters the hydrogenation liquid cooler, and then enters the bottom of the upper section of the oxidation tower. Fresh air is introduced from the bottom of the lower section of the tower and dispersed through the disperser to the tower. The amount of air introduced inside is controlled according to the oxidation efficiency and the oxygen content in the exhaust gas (usually about 6%). The hydrogenation liquid entering the bottom of the tower in the upper section and the gas from the built-in oxidation separator in the lower tower flow up side by side; the oxidizing liquid intercooler in the tower controls a certain temperature and then enters the lower section of the oxidation tower, and flows up side by side with fresh air. The tower has a built-in separator to separate the gas. The completely oxidized hydrogenation liquid (called oxidizing liquid) enters the oxidation liquid storage tank after a certain liquid level is controlled by the automatic control instrument, and then enters the bottom of the extraction tower with the aid of the oxidation liquid pump. The temperature in the oxidation tower is adjusted by the intercooler to control the amount of water introduced.

The hydrogenated liquid in the hydrogenation tank enters the hydrogenated liquid pump together with the phosphate water solution from the phosphate reservoir. With the hydrogenation pump through the hydrogenated liquid pump filter to further filter the solid impurities into the hydrogenated liquid cooler, and then into the bottom of the upper section of the oxide tower, from the bottom of the lower section of the tower into fresh air, and through the dispersion of the dispersor, the amount of air into the tower according to oxidation efficiency and oxygen content in the exhaust gas (generally about 6%)and control. The hydrogenated liquid entering the bottom of the upper tower is flowed together with the gas from the lower tower's built-in oxidation separator, and the gas is separated by the oxide tower's built-in separator after controlling a certain temperature and entering the lower section of the oxidation tower, which is separated by the oxide tower's built-in separator. The fully oxidized hydrogenated liquid (called oxidizing liquid) is controlled by the self-control instrument at a certain level and then enters the oxidation fluid storage tank, and then enters the bottom of the extraction tower with the aid of the oxidizing fluid pump. The temperature in the oxide tower is regulated by the middle cooler controlling the amount of water entered.

The hydrogenated liquid in the hydrogenated liquid storage tank enters the hydrogenated liquid pump together with the phosphoric acid aqueous solution from the phosphoric acid storage tank. With the aid of the hydrogenated liquid pump, the solid impurities are further filtered through the filter after the hydrogenated liquid pump, and then enter the hydrogenated liquid cooler, and then enter the bottom of the upper section of the oxidation tower. Fresh air is introduced from the bottom of the lower section of the tower and dispersed through the disperser. The amount of air into the tower is controlled according to the oxidation efficiency and the oxygen content in the tail gas (generally about 6%). The hydrogenated liquid entering the bottom of the upper tower and the gas from the built-in oxidation separator of the lower tower flow upward together; after a certain temperature is controlled by the oxidation liquid intercooler of the tower, the hydrogenated liquid enters the lower section of the oxidation tower and flows upward together with fresh air, and the gas is separated by the built-in separator of the oxidation tower. The fully oxidized hydrogenated liquid (called oxidation liquid) enters the oxidation liquid storage tank after a certain level is controlled by the automatic control instrument, and then enters the bottom of the extraction tower with the aid of the oxidation liquid pump. The temperature in the oxidation tower is regulated by the control of water flow through the intercooler.<br>
