YUHONG produce a high-capacity, custom-engineered shell and tube heat exchanger designed for demanding service in the oil and gas industry. Built to the highest standards, including TEMA Class R and ASME Section VIII, Div. 1, this unit exemplifies robust engineering for critical heat transfer applications between process streams. Its primary function is to efficiently recover heat from Atmospheric Residue to preheat Desalted Crude Oil, significantly improving energy efficiency and operational economics in refinery processes.
Robust Design and Construction
The heat exchanger is built as a TEMA Type AES (externally sealed floating head) design, which is ideal for applications with a large temperature differential between the shell and tubes, allowing for thermal expansion without stress.
Key design features include:
Tubes: 1,250 tubes with an outer diameter of 25.4 mm, arranged on a 31.75 mm 45-degree triangular pitch
Baffles: Features segmental cross baffles with a 23% cut and a spacing of 280 mm
Nozzles: Equipped with 8" 300# flange connections on the shell side and 10" 300# connections on the tube side
High-Grade Materials for Corrosion Resistance
Tubes & Tubesheets: Tubes are made from SA 213 Gr.T91, and tubesheets from SA 182 Gr.F91
Shell, Channel, and Covers: Constructed from SA 387 Gr.5 Cl.2, a chromium-molybdenum alloy steel
Gaskets: All gaskets (shell, tube, and floating head) use Soft Iron filled with Graphite
TEMA Standard: TEMA Class R (for severe refinery and process applications
Applications & Industries
This heat exchanger is specifically engineered for the hydrocarbon processing industry. Its primary application is within Crude Distillation Units (CDUs) for:
Preheating desalted crude oil using hot atmospheric residue.
Heat recovery systems to reduce fuel consumption in furnaces.
General heavy hydrocarbon service involving viscous fluids like residuum and crude oil.
