Liquid in the circulating hydrogen desulfurization tower
Thread Content
Recently, liquid from the circulating hydrogen desulfurization tower has flowed into the subsequent circulating hydrogen liquid separation tank, resulting in a level alarm in that tank. Therefore, the measure we took was to reduce the amount of lean liquid, while simultaneously opening the hydrogen side line of the circulating hydrogen desulfurization tower. The liquid level stopped rising instantly. This lean liquid is still quite clean; it’s just the rich liquid that is a bit dirtier and more turbid. After being left to stand for two days, the black substances can settle at the bottom. If it’s always like this, it won’t be effective at removing hydrogen sulfide. Do any of you experts have any good methods?
Based on your description, the liquid carried from the cyclic hydrogen desulfurization tower to the subsequent cyclic hydrogen separation tank may be due to the presence of deposits or impurities in the rich liquid. To improve the hydrogen sulfide removal efficiency, the following methods can be considered: 1. Regularly clean the circulating hydrogen desulfurization tower: Periodically clean the circulating hydrogen desulfurization tower to remove deposits and impurities from the liquid stream, thereby ensuring its proper operation. 2. Controlling the concentration of the rich liquid: By controlling the concentration of the rich liquid that enters the circulating hydrogen desulfurization tower, it is possible to prevent excessive impurities in the rich liquid from causing liquid carryover. 3. Improve gas-liquid separation: Increasing the size of the gas-liquid separator or optimizing its design can help separate liquid from gas more effectively, thereby reducing the occurrence of liquid entrainment. 4. Optimize operating conditions: Optimize the operating conditions of the cyclohexane desulfurization tower by adjusting parameters such as pressure and temperature, in order to improve gas-liquid separation efficiency and reduce liquid carryover. 5. Regular maintenance and inspection: Regularly perform maintenance and inspection on the recycle hydrogen desulfurization tower and related equipment, and follow the prescribed maintenance procedures to ensure the normal operation of the equipment. The above are some common methods; they should be used in combination depending on the actual situation. If the problem remains unresolved, it is recommended to consult professionals in the relevant field to obtain more specific advice and solutions. .
