Compressed Air System Study
Client : Aluminerie Lauralco (2023 to 2024)
Location : Deschambault, Quebec, Canada
Year : 2024
Potential grant: $8.85M
The Deschambault aluminum smelter is renowned for its operational expertise. Its world-renowned laboratory provides aluminum smelter-related systems analysis services to customers worldwide. The Deschambault aluminum smelter is currently working to minimize its energy losses in order to maximize the energy allocated to aluminum production.
In this context, through its partner R. O. Poirier, LDV Consultants was mandated to help optimize their air system as well as to analyze potential heat recovery of the plant's compressors.
LDV has identified a number of energy efficiency measures that could reduce compressed air consumption from 15,500 scfm to 5,700 scfm, with potential financial assistance from Hydro-Québec of up to $8,850,000 if all the measures are implemented. These measures include adding a reservoir and balancing line downstream of the compressors, replacing a pneumatic alumina conveyor with a bucket conveyor, and implementing VFD compressors.
Assessing the Ventilation and Compressed Air Systems
Client : Eldorado Gold (2019 à 2022)
Location : Val-d’Or
Year : 2022
Grant: $2.50M
Eldorado Gold Québec is focused on the expansion and development of the Lamaque underground gold mine, located near Val-d'Or. As the mine is in the process of developing rapidly, investments have been made to implement an on-demand ventilation system.
Within this scope, through its partner R. O. Poirier, LDV Consultants was mandated to assess the ventilation and compressed air systems currently installed at the mine and mill. Once the systems had been assessed, our team produced an energy efficiency report and recommendations for the implementation of an on-demand ventilation system and optimization of the compressed air system. As a result, Eldorado Gold received $2,500,000 in financial assistance from Hydro-Québec to proceed with their energy management improvement projects.
Ventilation System Analysis
Client : Goldcorp (2015 to 2019)
Location : Éléonore Mine, James Bay, Quebec
Year : 2019
Grant: $3.40M
Goldcorp (now called Newmont Corporation) is a gold mining company operating throughout the Americas, mainly in Canada, Mexico and Argentina. One of their mines is the Éléonore gold mine, located in Eeyou Istchee/James Bay, in a remote corner of the Northern Quebec region.
As part of a project to improve the mine's energy management, through its partner R. O. Poirier, LDV Consultants was mandated to assess the currently installed ventilation system to determine the feasibility of implementing an on-demand ventilation system.
A ventilation capacity of 12,000 HP for a total of 112 fans was identified, resulting in considerable energy savings. Hydro-Québec awarded Goldcorp a $3,400,000 financial aid to implement the energy efficiency measures recommended by our team.
Pumping System Analysis
Client : Résolu Produits forestiers (2014)
Location : Baie-Comeau
Year : 2014
Résolu Produits forestiers is a major manufacturer of various products, such as wood, pulp, tissue and paper, sold in over 60 countries. The company manages about 40 facilities and owns power generation assets in Canada and the United States. To reduce their electrical energy consumption, Resolute Forest Products contacted LDV Consultants to explore potential energy efficiency solutions.
With this in mind, through its partner R. O. Poirier, LDV Consultants was mandated to assess the potential reduction in electrical power used by the water pumping system.
After analyzing the pumping and cooling systems of the mill and foundry, a total of 4,200 HP was identified, with a potential consumption reduction of 28%.
With regard to the energy consumption of the furnace combustion fans, 750 HP has been identified, with a potential reduction of 38%.
