[Translate to Englisch:] Schmidt + Clemens contributed two core technologies to the IMPROOF project:

• Centralloy® HT E – a high-temperature Ni-based alloy with a stable aluminum oxide layer, ensuring prolonged tube life, reduced carburization, and enhanced resistance to coking under cyclic operation.
• SCOPE® Fusion HT E – a patented internal profile geometry that enhances feed gas flow, improves heat transfer, and lowers skin temperatures. The combination of material and geometry significantly increases tube longevity and energy efficiency.

These technologies were evaluated against alternative solutions and ultimately implemented in the project’s demonstration furnace.

During the course of the project, SCOPE® Fusion HT E was benchmarked against conventional tube systems. Results showed:

• Significantly lower coke formation
• Improved feed conversion and product selectivity
• Lower tube wall temperatures
• Extended operational cycles without tube failure

The technology was installed in the project’s demonstration furnace, which was later named “the world’s most efficient steam cracker.” Performance targets were not only met but exceeded in key areas such as emission reduction and thermal efficiency.

After laboratory-scale trials, an end-user’s steam cracker was equipped with SCOPE® fusion HT E Coils. The result left no room for doubt. Compared to standard materials, S+C’s technology significantly reduces the greenhouse gasoutput, while at the same time raising the efficiency of the cracker.
