As the title suggests, what effects does excessive pressure in the electrodialysis tank have on its operation and subsequent processes?
If the pressure in the electrodialysis tank is too high, as long as it remains within the designed pressure range for the tank and its operation, there is no significant impact; however, it will cause an increase in the current drawn by the pump, resulting in power waste. If the pressure exceeds that of the safety valve, it will cause............................................
Our safety valve failed, and oil gushed out from the underground funnel, like a fountain!
Control measures must be taken; although safety valves are installed, from a safety and environmental protection perspective, a safety valve vent tank should also be added
If the operating pressure is too high, and the difference between it and the set pressure value of the safety valve is small, along with large operational fluctuations, this can cause the safety valve to activate. Pressure has little impact on other operations.
Our safety valve failed, and oil gushed out from the underground funnel, like a fountain! Later, the safety valve was removed; it mainly depends on whether the temperature of the feed water for desalination is high Furthermore, the water separation in the crude oil tank area is incomplete, resulting in severe water contamination. Do you have dual lift pipes and a dual fractionation tower? If so, do it this way. Reduce the pressure in the light oil fractionation tower from the rear. Large amounts of light oil acidic water are discharged externally. Pay attention to the low temperature in the light fractionation tower. Below 120 degrees, the oil pump at the bottom of the tower is prone to cavitation.
If the pressure in the electrodialysis tank exceeds its operating and design pressures, it can damage the tank; therefore, safety valves, pressure relief lines, and pressure relief tanks are necessary to prevent equipment damage due to overpressure and resulting accidents.
Firstly, a high pressure in the electrodesalination tank is often due to significant water content in the crude oil. Failing to remove this water can lead to high pressure in the crude oil tank, and it may also cause overpressure in the distillation tower system. This has happened in our plant, resulting in the electrodesalination tank activating its safety valves; had the pressure relief mechanisms downstream of the distillation system not worked promptly, the safety valves of the distillation tower could have activated as well. The reasons for this are inadequate water removal measures in the crude oil storage area, as well as high water content in the crude oil used in processing. Therefore, it is still necessary to strictly control the water content in crude oil.
