U-tube shell and tube heat exchanger.
Design Configuration: It features a "U" tube bundle design, which allows for free thermal expansion, making it ideal for the high temperature differentials found in refinery processes.
Specific Application: It serves as the Stabilizer Feed Exchanger within the Naphtha Coker Hydrotreating Unit.
Core Function: The equipment manages the heat exchange of Hydrocarbons and Hydrogen (HC + H2) streams to preheat feed materials for the stabilization column.
