How many days does it take to load 1.4 million tons per year of diesel hydrogenation catalyst?
Thread Content
We need a start-up schedule for the commissioning of our new plant. May I ask those who have experience with diesel hydrogenation: how many days does it take to load the catalyst? How many days does it take to sulfide and stabilize a catalyst? Thank you!
If a professional team handles the installation, 72 to 84 hours should be sufficient without any problems； The vulcanization and curing times can be determined based on the times specified in the scheme provided by the catalyst manufacturer.
Those who recommend Jiangsu Tianpeng coating agents: maximum 3 days
A specialized team for loading the material will take about 3 days, vulcanization takes around 38 hours, and stabilization takes approximately 24 hours
The main time-consuming tasks are the lifting of the catalyst and the installation of the tower internals; 3-4 days should be sufficient. The sulfurization and stabilization process takes about 60 hours.
It depends on how many bed layers there are. The most time-consuming aspects of catalyst loading are the filling of the upper and lower ceramic balls of the main component as well as the protective layer, since leveling them takes time; moreover, it is also crucial that the internal components can be installed quickly. For a plant with a capacity of 1.4 million tons, the amount of catalyst needed is just over 100 tons; if everything goes well, three days should be sufficient. Two days is definitely enough for the sulfidation process from start to finish. Stability is not guaranteed; different catalyst manufacturers have different requirements, with more than 3 days being considered appropriate.
They specialize in catalyst loading and unloading as well as skimming, and they have good engineering quality and a solid reputation
