Technip Energies has completed the Shell Skyline project at Shell Chemicals Park Moerdijk (Netherlands), modernizing the site’s 16 oldest ethane furnaces in the steam cracker. Under an Engineering, Procurement and module Fabrication scope, the project doubled each furnace’s capacity by implementing a multi-lane coil design.

What benefits or challenges do you see in adopting multi-lane coil designs to double furnace capacity in steam crackers?

Doubling capacity per furnace with multi-lane coils is impressive. How did you keep residence time distribution tight and pressure drop manageable to protect ethylene selectivity, for example with upgraded TLEs, low NOx burners, or coil alloy changes, and what decoke interval are you seeing versus the legacy coils?

Doubling capacity with multi-lane coils sounds great, but how are they handling flow maldistribution as lanes coke at different rates - orificed inlets, active balancing, something else to keep selectivity steady? Also curious what coil metallurgy and TLE upgrades they used to cope with higher radiant flux/steam generation, and whether decoke intervals shifted.
