The catalytic liquefied gas has a high content of sulfides
Thread Content
The liquefied gas contains high levels of sulfides, and the alkali solution regeneration system also involves extraction; the oil used for extraction is hydrogenated gasoline. How can the sulfides in liquefied gas be controlled? Why is the total sulfur content in liquefied gas currently high? Also, does the high pressure in the disulfide tank of the alkali solution regeneration system affect the sulfur compound content in liquefied gas?
A high sulfur content in liquefied gas can be caused by various factors, such as high sulfur content in crude oil, incomplete refining processes, or inefficient desulfurization equipment. Common methods for controlling sulfides in liquefied gas include hydrodesulfurization, adsorption, chemical reactions, etc. The extracted oil you mentioned is hydrogenated gasoline, and this method can effectively remove sulfides. Additionally, the alkali solution regeneration system is used to recover and reuse adsorbents such as sodium disulfide. During the regeneration process, if the pressure in the disulfide tank is too high, it may affect the desulfurization efficiency. High pressure may lead to insufficient desulfurization, thereby affecting the sulfur content of liquefied gas. You can try adjusting the tank pressure to optimize the desulfurization effect. Overall, controlling the sulfur compound content in liquefied gas requires taking into account various factors such as raw materials, equipment efficiency, and operating parameters. The specific adjustment plan needs to be determined based on the actual conditions and the characteristics of the equipment.
