The sulfur content in the raw material exceeds the standard
Thread Content
What impacts will excessive sulfur content in the feedstock of a hydrogenation unit have on the unit?
Is the sulfur content higher than that of the designed raw material, or does it exceed the limit set for the designed raw material? The sulfur content in the raw materials used for our device design is 3000 PPm, with a limit of 8000 PPm?
It depends on the extent of the excess. Generally, for devices, as long as the product quality isn’t at the critical level, a slight excess should not affect the quality of the product.
Our unit’s design value is 150, while the actual value reaches around 1200
1. Within the existing process parameters, the products are prone to failing quality standards. 2. The load on the desulfurization system increases. 3. The purity of the recycled gas decreases. 4. Equipment corrosion worsens. 5. If sulfur recovery is available in the facility, the sulfur production increases: lol
Will the temperature rise of the reactor also increase?
Since we use two-stage hydrogenation, the feed temperature in the second stage is controlled by a heating furnace, so the temperature rise is not very significant.
Hello, I would like to ask whether the catalyst used in the second stage of your secondary hydrogenation is a precious metal The S content in your raw material is above the limit; does the desulfurization effect achieved in the first stage of purification meet the requirements, and is it sufficient for the catalyst used in the second stage? Are there any differences in the S content of the oil after the first stage of refining between the cases of increased S content in the crude oil and normal conditions? Is there still a period of refined temperature with no change? I’m also considering the issue of the S content in our raw materials these days
