What are the characteristics and measures of hydro-mechanical seal hydrofining?

The eight most common typical mechanical pump processes are atmospheric and vacuum distillation, catalytic cracking, alkylation, platinum reforming, hydrofining, desulfurization, propane deasphalting, ketone-benzol dewaxing and grain aldehyde refining. Dongsheng seal tells you about the working characteristics and measures of mechanical seal of catalytic and cracking slurry pump. We will briefly introduce these eight typical hydro-mechanical seals and analyze the auxiliary measures in stages. Working characteristics and measures of mechanical seal of FCC slurry pump;

Hydrorefining feed pump has high temperature and high viscosity, and the washing liquid is easy to solidify. Low tower pump has less slurry residue and good lubricity. Metal bellows seal or multi-point small spring seal should be used. The flushing fluid should be controlled within the range of 130 to 163 degrees Celsius. The standby pump can prevent solidification and can be used as the conveying fluid for running the pump.

Hydrorefining (field: petroleum processing), also known as hydrotreating, is one of the most important refining methods of petroleum products. In the presence of hydrogen pressure and catalyst, harmful impurities such as sulfur, oxygen and nitrogen in oil products are converted into corresponding hydrogen sulfide, water and ammonia to be removed, and olefins and dienes are partially hydrogenated and saturated, thus improving the quality of oil products. Sometimes, hydrofining refers to the refining and upgrading of light oil products, and hydrotreating refers to the refining and desulfurization of heavy oil products.
