Understanding the effect of Ca and Mg ions from wastes in the solvent regeneration stage of a biogas upgrading unit

This paper reveals the effect of calcium and magnesium ions in carbonation experiments carried out to regenerate sodium hydroxide from a biogas upgrading unit. This novel study arises as an alternative to standard physical process whose elevated energy consumption imposes economic restrictions. Prev...
