N2O Abatement Project

Dyno Nobel were looking to further reduce their N2O and NOx emissions through the addition of a thyssenkrupp abatement reactor. The addition of this reactor required changes to operating conditions in the plant which is highly integrated. Prudentia were engaged to initially do a process engineering review to verify the proposed process model / conditions for this plant modification. From that work, we were awarded the complete design package for the project.

Solution

The proposed use of a new tertiary N2O and NOX abatement reactor required the replacement of another vessel within the plant that was managed by Dyno Nobel.  Integrating the plant modifications for that vessel was incorporated into the project scope, mainly being the structural and piping works associated with the required larger vessel size. The new abatement reactor was installed external to the main plant building due to its size and for ease of construction.

Prudentia initially produced a preliminary design package focussing on mitigating key risks identified by Dyno Nobel to ensure there were no fatal flaws with the project concept. From sanction of the project, Prudentia executed the detailed design for the plant under a lump sum working closely with the Dyno Nobel projects team to expedite critical path deliverables to meet the project shutdown window. This included not only integrating the vessel but adding connections to the natural gas system and integrating instruments / valving into the existing electrical system. As additional support to the project, Prudentia provided third party design verification and RPEQ services to the abatement system supplier.
