Services for Steam Cracker

Coil Hardware Optimization

Tailored coil configuration that fits your needs

In order to improve the availability of Steam Cracker Furnaces, it is essential for operating and management personnel to have an understanding of the most common causes of failure in pyrolysis coils, cross-overs, transfer lines etc. , relevant to their own plant and mode of operation.

Thus, as inventor and manufacturer of ground-breaking alloys and heat transfer enhancing technologies we are delighted to show you the most appropriate radiant coil configuration.

Advanced Steam Cracking Technologies

Generate added value for the Petrochemical Industry

S+C operates one of the industry’s largest research and development departments and has unrivalled and unique technical equipment and expertise. We use this department to continuously improve our materials and products and their performance.

This is particularly relevant for the two sophisticated materials of our Centralloy® family: Centralloy® HT E for steam crackers and Centralloy® G 4852 Micro R for steam reformers.

A further product innovation is SCOPE®. SCOPE® tubes feature inside profiling which provides considerable higher heat conductivity (heat transfer), thus increasing furnace productivity.

S+C Centralloy® Materials

Wide product range of high temperature resistant materials, including the unparalleled Centralloy® HT E for extended cracking cycles and longer tube lifetime.

Increased run length due to an aluminum oxide layer, thus reducing catalytic coke formation
Higher feed rate/conversion potential with the same run length, resulting in
Increased coil service life due to aluminum oxide layer, thus offering:
- protection against embrittlement
- protection against corrosion
- higher resistance during operational transients

S+C SCOPE® Inner Profile

Customizable 3D inner profile to address the special needs of steam cracking for optimized performance.

Increased run length due to lower TMT & coke formation
Higher product selectivity due to gas temperature balancing, i.e. insufficient cracking and/or excessive cracking
Increased energy efficiency or higher feed rate/conversion potential due to higher heat transfer
Increased coil life due to lower tube temperatures, less carburization

Tailored Solutions

Coil Designs for every process requirement

Different coil passes have different requirements regarding material and profile choice. Here we define these needs and create several models with different combinations. We can prepare several configurations and comparisons, and show you their benefits.

Through simulation and different iterations, we are able to show you the benefits of using our materials and profile technologies. This ultimately leads to a tailored coil configuration that fits your needs, whether they are reliability, performance, yield or cost.

Enhancing the heat transfer leads ultimately to reduced metal temperatures and longer runs

Less pressure drop means more selectivity on desired products

How it works

From understanding to optimization

From feedstock and coil design to operating strategy, each steam cracker has its own performance profile. That’s why every hardware optimization begins with identifying your specific requirements. We guide you step by step, by combining detailed technical insights, advanced simulation tools, and our metallurgical expertise, towards a solution tailored precisely to your process.

Current state definition

Understanding through communication

In order to optimize we have to understand your needs and demands.

Through close communication we can gather information about your current configuration and gain an overview of your system and requirements.

Simulation

Information leads to modeling and to simulation

Using this overview and the information gathered, we create models of your coil using state-of-the-art software.

Combination of technologies

Iteration leads to solution

Different coil passes have different requirements regarding material and profile choice. Here we define these needs and create several models with different combinations.

Optimization

Your coil, your best fit

Through simulation and different iterations, we are able to show you the benefits of using our materials and profile technologies.

This ultimately leads to a tailored coil configuration that perfectly fits your needs, whether they are costs, reliability, performance or yield.

The Result

Your coil, your best fit

Based on the process data and subsequent simulations S+C recommend to implement a combination of Centralloy® Materials, SCOPE® and SCOPE® Fusion HT E.
