Kruger Gatineau mill recovers heat, cuts CO2
Quality tissue manufacturer Kruger Products LP is cutting its CO2 emissions with an innovative heat recovery technology that is now operational at its Gatineau, Que. mill.
GATINEAU, Que.: Quality tissue manufacturer Kruger Products LP is cutting its CO2 emissions with an innovative heat recovery technology that is now operational at its Gatineau, Que. mill.
The $4.8 million project involves Thermal Energy International’s FLU-ACE system, which will lower the mill’s total energy consumption by 11% and CO2 emissions by 14.5% (10,000 tonnes per year), a reduction Kruger said is equivalent to removing 2,500 cars from the road or planting 1.3 million trees.
The central heat recovery system will capture hot, humid air from two of the mill’s three paper machines and reuse it to heat process water and the facility during the winter months. The system pulls the hot exhaust from the paper machines and forces it through an energy recuperation tower. Water is sprayed into the tower and energy is drawn from the exhausted air to the water. The water is then filtered and circulated through separate heat exchangers to transfer the energy to the process.
Kruger said the third paper machine is already using heat recovery technology.
Part of the financing of the project comes from Québec’s Agence de l’efficacité énergétique, which granted $1.9 million in financial assistance through its Heavy Oil Consumption Reduction Program.
The Gatineau mill project is one of several initiatives Kruger Products has implemented as part of Sustainability 2015, a five-year plan to reduce its environmental footprint.
Thermal Energy International is an energy and emissions technology company based in the UK with offices in Ottawa.
