Replace cooling units and recover waste heat

Chillers are essential to regulate the temperature of machines and production circuits. Those of the Alban Muller plant needed to be changed to improve the plant's energy performance.

In addition, Alban Muller's teams had identified significant heat loss. Indeed, there was no fatal heat recovery system on the chillers.

Alban Muller has set himself the objective of reducing CO80 emissions due to heat loss by 2%.

Change of cold units and heat recovery
with Dametis Project

The Alban Muller site called on Dametis to change the cold units and to set up a more efficient heat recovery system.

The solutions provided by Dametis have made it possible to save 81,92% in 2 years on the gas bill for the scope of domestic hot water production, which is more than the 80% objective.

Challenge: reduce carbon emissions by 50% by 2030

In March 2021, Alban Muller joined Croda International. The British chemicals and cosmetics group has set ambitious decarbonization targets for factory production.

Using 2 CO2018 emissions as a baseline, Croda International aims to reduce emissions by 50% by 2030 and 100% by 2050.

These objectives concern direct on-site emissions such as gas consumption and company vehicles (scope 1), as well as indirect energy emissions, and in particular electricity consumption (scope 2).

Optimize processes to improve performance with Dametis Expertise

1. During the first visit, the Dametis experts carried out an energy audit, inventoried the plant's equipment and collected as much data as possible relating to gas and electricity consumption.
   After measuring the performance gaps between the plant's current processes and their optimal levels, they proposed areas for improvement to reduce CO2 emissions zone by zone.
2. During a second on-site visit, Dametis experts established a measurement plan and defined the places to install sensors to improve performance. For areas where data collection is insufficient, they have defined the additional measurements to be carried out to obtain a relevant quantitative analysis.
3. Dametis Expertise has put in place an action plan based on a decision matrix which makes it possible to choose the priority areas of intervention according to the potential return on investment and the difficulty of implementation.
4. Dametis offers long-term energy support with monitoring of the action plan and carrying out dedicated studies on the points with high potential for energy reduction identified during the audit.
