Oil Refining

1. Industry Demand

Core petroleum refining processes, including atmospheric-vacuum distillation, catalytic cracking and hydrofining, face extreme working conditions of high temperature & pressure, severe coking and fouling, strong acid corrosion and strict temperature control. Heat exchangers are required to deliver outstanding temperature resistance, anti-coking performance, high efficiency and structural stability to ensure long-term unit operation and stable product quality.

2. Core Working Stations

Core working scenarios cover high-temperature heavy oil cooling for distillation, slurry heat exchange for catalytic cracking, high-pressure precision heat exchange for hydrofining, side-stream medium cooling, feed preheating and system waste heat recovery. Widely used in main refining units and auxiliary energy-saving renovation, it stabilizes production conditions, improves throughput and reduces overall energy consumption.
