Byrne
Ó Cléirigh were appointed project managers for the
procurement and installation of a Regenerative Thermal
Oxidiser (RTO) to treat poly-aromatic hydrocarbon (PAH)
emissions from a plant producing dry anode paste for the Söderberg process at Kubal.
The Kubal plant produces about 100,000
tonnes of aluminium per annum, using both Söderberg and Pre-bake
technology.
Byrne Ó
Cléirigh's primary roles in this project included:
 | Monitoring
the nature and scale of the emissions; |
| Arranging
RTO pilot plant trials and assessing results; |
|
Specification
of abatement system for removal of PAHs; |
|
Management
of competitive tendering process & selection of vendor; |
|
Contract
management & certification of payments; |
|
Design
review & technical support; |
|
Hazard
& Operability Studies; |
|
Plant
inspections at project milestones; |
|
Supervision
of acceptance performance tests. |
The RTO plant
selected for installation is designed to achieve a destruction
and removal efficiency for PAHs of greater than 99% for a
combined process flowrate of up to 8,000 Nm3/h.
The combined process flow consists of streams from several sources containing
different
concentrations of PAHs.
The plant successfully passsed its performance test.
