Description of the way in which the entity carried out its assessment |
||||||
|
Queensland Nitrate Pty Ltd (QNP) is a joint venture involving Dyno Nobel and CSBP (Wesfarmers). Dyno Nobel was acquired by Incitec Pivot Pty Ltd (IPL) in 2008. As its only operation, the Moura Ammonium Nitrate Plant accounts for 100% of the energy use of the company.
QNP has sought to meet the formal requirements of the Energy Efficiency Opportunities Regulations by preparing assessment reports for the site. In some cases assessments were initially completed to satisfy the EITE and NGERS programs. These assessments were modified where necessary to meet the intent and key requirements of EEO legislation. QNP has used qualified in house staff for the assessments, supplemented by advice from external corporate specialists.
Site-wide energy use (Natural Gas and Electricity) presented for this assessment period has been determined from commercial invoices and statements. Energy savings for individual opportunities have been calculated using internal mass balance techniques and process data system (PI System). In this document QNP is reporting on 100% of the total energy to be assessed in the first EEO cycle. |
||||||
* Please note that, for individual sites that use more that 0.5PJ of energy, all energy use must be assessed (less a small proportion for non integral energy use).

Description of Opportunity |
Voluntary Information |
|
|
Gas compositions around the ammonia synthesis loop are not adequately known. Better knowledge of the compositions can allow for fine tuning of the process, leading to improved conversion efficiency and reduced use of natural gas. |

Description of Opportunity |
Voluntary Information |
|
|
Automation of Nitric Acid Plant Start-ups can reduce the number of plant trips. The plant is at its maximum energy efficiency at design rates. Any period where a plant is in the process of ramping up to full rates is associated with lower energy efficiency, so any measure that reduces trips will reduce energy over a year. |

Description of Opportunity |
Voluntary Information |
|
|
The Nitric Acid plant air filter was undersized, meaning that it was prone to blockage from airborne dust during adverse weather conditions, resulting in maintenance downtime with associated reduced energy efficiency. The Air Filter was replaced with a larger unit. This has resulted in lower overall current draw and lower incidence of contamination of catalyst.
