Traditional sealing solutions are inadequate for ethylene production.

The oxidising environment and thermal cycling, exacerbated by regular decoking sessions, create harsh operational conditions that put plant equipment under significant stress. Tests and operational experience have shown that choosing the right sealing gaskets and materials can make the difference between joint failure and efficient production.

Flexitallic sealing solutions such as Thermiculite® and Change™ hold the potential to reduce the operating costs associated with maintenance downtime while achieving maximum plant safety. How?

  • Temperature

    Temperatures can reach up to 1000°C (1830 °F) in the steam cracking furnace, which places significant stress on joints.

  • Thermal cycling

    As a result of maintenance shutdowns, decoking sessions and the cooling process, thermal cycling causes expansion and contraction of joints. An effective sealing solution must be able to respond and adapt to this recurring demand.

  • Oxidation

    The oxidising environment created by the high temperature steam and decoking sessions initiates an oxidising reaction with traditional sealing materials, which means they lose mass and ultimately cause leaks.

Choosing the right sealing solution in ethylene production

The operational challenges of ethylene production call for a thorough approach to gasket selection. In this technical paper, our experts describe the sealing challenges caused by the oxidising environment created by the superheated steam, thermal cycling and regular decoking sessions, highlighting the hotspots where traditional sealing solutions are known to cause joint failure.
