CRUDE OIL REFINERY
Crude oil refining involves complex thermal cycles, aggressive media, and high-pressure environments. Heat exchangers must ensure stable operation in demanding units such as atmospheric distillation, vacuum distillation, and catalytic cracking.

The main challenges in this sector
The main challenges in this sector
Extreme operating temperatures
Many refining steps involve high inlet temperatures exceeding 400°C. Thermal equipment must maintain performance without fatigue or leakage.
Highly corrosive fluids
Crude oil often contains sulfur, chlorides, and acids that promote corrosion during preheating and residue processing. Materials must resist these conditions over time.
Continuous 24/7 operation
Refineries operate nonstop with tight schedules. Any shutdown or fouling can result in significant production and revenue losses.
Critical energy recovery
Energy efficiency is key. Effective heat recovery between hot and cold streams significantly reduces fuel consumption and environmental impact.
Our involvement in the sector
Nexson delivers robust, compact, and high-performance exchangers that maximize uptime and energy savings across refinery operations.
Improving heat recovery in demanding refinery operations
Welded construction for leak-free reliability
Our 100% welded design guarantees tight sealing and safe operation even under high temperature and pressure. This ensures process continuity in preheat trains and high-duty loops.
High thermal performance and fouling resistance
Spiral and plate-type exchangers offer enhanced turbulence, reducing fouling in heavy oils and improving heat transfer efficiency for crude preheating or vacuum residue cooling.
Applications across refinery units
Nexson units are integrated into desalter preheat, heat recovery from fractionation columns, catalytic reformer loops, and flare gas recovery. They reduce energy demand and support better thermal integration.
Custom materials for harsh refinery environments
Our exchangers are available in stainless steel, duplex, and nickel alloys adapted to hot, corrosive, or high-viscosity streams, ensuring durability and operational safety.
