CA 2579797

The invention relates to a process for providing tall oil or tall oil fuel from tall oil soap. In the process, tall oil soap, which may be neutralized with carbon dioxide, is treated with an alkaline earth metal compound to convert sodium soaps into alkaline earth metal soaps. The conversion reduces the sodium content and increases the heat value of the product. The converted product may be used to provide a low sodium fuel or it may be acidulated with a minimum of sulfur.

La présente invention a pour objet un procédé d'obtention d'huile de pin ou de carburant à base d'huile de pin à partir de savon d'huile de pin. Dans ledit procédé, le savon d~huile de pin, qui peut être neutralisé à l~aide de dioxyde de carbone, est traité avec un dérivé de métal alcalino-terreux, ce qui aboutit à la conversion des savons de sodium en savons dudit métal alcalino-terreux. Ladite conversion réduit la teneur en sodium du produit et augmente sa valeur calorifique. Une fois converti, le produit peut être employé afin de produire un carburant à faible teneur en sodium. Il peut également être acidifié avec une quantité minimale de soufre.
