The W-02A/B Kerosene Cooler represents a highly specialized engineering solution specifically developed for deployment within the high-throughput downstream environments of modern Crude Distillation Units (CDU). As an essential component of the refinery’s heat integration and product fractionation stream, this heavy-duty shell-and-tube heat exchanger is designed to safely, efficiently, and continuously lower the temperature of highly flammable kerosene fractions extracted from the distillation column before they progress to downstream storage or blending facilities.
Design Standards & Codes: ASME Section VIII Division 1 (Rules for Construction of Pressure Vessels); TEMA Class R (Standards of the Tubular Exchanger Manufacturers Association for Petroleum Refinery Services); EN ISO 12020-BF.
Dimensional Tolerances: Compliant with EN ISO 2768-cL / m standard criteria for general linear and angular dimensions in heavy industrial manufacturing.
Nozzle Configurations:
Kerosene Inlet & Outlet (N1, N3 / N2, N4): DN 150 Class 4 Ratings
Cooling Water Inlet & Outlet (N5, N7 / N6, N8): DN 300 Performance Design
Auxiliary Ports: Venting (N9, N11) at 180mm sizing, Draining (N10, N12) at 6000/180mm rating, and specialized instrumentation connections (N13–N20).
Allowable Nozzle Loading: Calculated based on the precise PN times F_{x000} structural matrix. The engineering tolerance accommodates up to 2.387 times 10^3{N} force across major process connections under peak operating dynamics.
Testing & Quality Assurance: 100% Manufacturer-certified Hydrostatic Test. Includes dedicated processing loops for filling (N8, N6, N3, N1), venting (N8, N6, N11, N9), and thorough system draining (N7, N5, N2, N4, N10, N12).
Structural Joint Efficiency: Full radiographic examination and ultrasonic testing verification on all critical shell-to-channel and head assembly welds. Joint efficiency designed up to 1.0 for severe-duty service.
Surface Treatment: High-durability industrial anti-corrosion coating, scale-resistant primer, and sandblasted surface finishing to withstand aggressive outdoor refinery ambiances.
Operational maintenance and longevity are integrated directly into the physical design layout. The system includes independent, high-capacity venting (N9, N11) and draining (N10, N12) ports across the body components. This allows for swift, safe isolation and complete purging of fluids during scheduled refinery turnaround cycles. The manufacturer conducts intensive hydrostatic testing to verify absolute zero-leakage performance before shipment. Every unit is delivered with a permanently fixed stainless-steel nameplate (W-02A/B standard specification) providing complete material traceability, fabrication serial records, and operating limit logs. With full joint efficiency execution and complete non-destructive examination (NDE) of all welded connections, the W-02A/B Kerosene Cooler stands as an industry-standard, high-reliability choice for severe refinery process heat transfer duties.
