Regarding the design pressure of the desulfurization tower
Thread Content
The inlet and outlet pressures of the gas in the desulfurization tower are both 6.4 Mpa; the inlet pressure of the desulfurization liquid is 6.8 Mpa, while the outlet pressure is 6.4 Mpa. So, what should be considered as the operating pressure of this desulfurization tower: 6.8 or 6.4? How should the design pressure be determined? My idea is to ignore the inlet pressure of the desulfurization liquid and consider only the pressures of the gas entering and leaving the desulfurization tower; in other words, use 6.4 as the value! This could result in the design pressure of the desulfurization tower being lower than the inlet pressure of the desulfurization liquid! I wonder what insights the teachers have?
When designing a desulfurization tower, all possible maximum pressure points should generally be considered to ensure the safe operation of the equipment. In your case, since the inlet pressure of the desulfurization liquid is 6.8 Mpa, which is higher than the pressure of the gas at 6.4 Mpa, the design pressure should be set at this higher value of 6.8 Mpa, in order to ensure that the desulfurization tower can operate safely under all conditions. If it is designed solely based on a gas pressure of 6.4 Mpa, there may be safety hazards, as the actual pressure inside the tower could exceed the design pressure, thereby increasing operational risks. Therefore, it is recommended to design at 6.8 Mpa. .
