Add a sampler to the diesel hydrogenation unit
Thread Content
Since there is no sampler at the reactor outlet of the diesel hydrogenation unit, it is difficult to determine the sulfur content in the refined diesel. Currently, the sulfur content of refined diesel can only be analyzed by taking samples at the point where the refined diesel leaves the unit. If the sulfur content in the refined diesel is high, it is not possible to determine whether this is due to poor refining efficiency or leakage from the high-pressure systems. To address this issue, it is recommended to install a sampler at the reactor outlet of the III diesel hydrogenation unit.
By introducing perturbed hydrogen into the raw material heat exchanger, the material undergoing heat exchange is disturbed within the exchanger, which reduces the dead zones in this heat exchanger. As a result, the heat exchange efficiency improves, and the amount of fuel required by the heating furnace is reduced, thereby achieving energy savings and lower consumption.
Standard design drawings include a sampling device for use after the reaction. Perturbed hydrogen? I’ve never heard of that; is it some new technology? Will such perturbations affect the stability of the feed? Our high-pressure heat exchangers have U-shaped tubes in their tube bundles, with baffle plates installed on them, so cross-flow should not occur. Could you explain in more detail what is meant by perturbed hydrogen?
