Ethylene cracking furnace coils

Industry Development Background

SETTING

Industry Background

In ethylene cracking plants, coke formation in the cracking furnace is a major problem affecting the long-term operation of the ethylene plant. Domestic ethylene producers widely use heat-resistant alloy ethylene cracking furnace tubes, which have a high tendency for coking, short decoking cycles, high energy consumption, high production costs, low efficiency, and seriously affect product quality and the environment.

Industry Pain Points

Furnace tube coking

Increased tube wall thermal resistance and energy consumption.
The inner diameter of the furnace tube decreases, resulting in a decrease in production.

Furnace tube carburizing

The ductility and creep properties of the furnace tubes decrease;
When the carburized layer reaches a wall thickness of 60%, the furnace tube is judged as scrap.

Severely polluted

Increase CO₂ emissions;
Increased air pollution.

Solution

NH1949 Anti-coking New Material

Extending the decoking cycle and extending the service life of furnace tubes reduces costs and increases efficiency, allowing the cracking furnace to operate more efficiently.

3D Digital Bending Tubes

Solved the problems of furnace tube coking and premature failure caused by the inability to polish the internal welding roots of U/S bend pipe assemblies.
