Colombia – Investing in a gas fired CHP

Sustainability case study: To guarantee 100% availability of power at our paper mill in Barranquilla in Colombia, sufficient electricity needs to be produced on site.

To meet this requirement, two relatively small gas turbines for electricity production were installed several years ago. Necessary steam was produced through a separate gas fired steam boiler. To optimise the energy situation on site, we have replaced the existing gas turbines and separate steam boiler by a new CHP installation consisting of one large turbine which is connected to a waste heat recovery boiler to produce the needed steam.

This investment became operational in May 2012 and will result, through the more efficient production of both electricity and steam, in a lower consumption of natural gas and consequently an annual reduction of some 20% of the mill’s direct fossil CO2 emissions.
