May I ask about the location where the contaminated oil from the hydrocracking unit is discharged?
Thread Content
The hydrocracking products are sent to the sludge oil system; in some designs, they leave the plant directly after the sludge oil water cooler, while in other designs they pass through the water cooler first for cooling before leaving the plant. What is the basis for such design choices?
The location selection for the sludge oil outlet in a hydrocracking unit is primarily determined by safety considerations and the impact on subsequent treatment processes. The choice to install it after the dirty oil water cooler is mainly due to the fact that cooling the dirty oil reduces its temperature, resulting in greater safety and stability. If the unit is installed in front of the water cooler, it is necessary to assess the impact of contaminated oil at higher temperatures on the pipes and equipment. The overall design considerations include safety, cost-effectiveness, and minimal environmental impact. .
