Combustion of Soap in Kraft Recovery Boilers, 2016 Pulping, Engineering, Environmental, Recycling, Sustainability (PEERS) Conference Proceedings


At softwood kraft pulp mills soap generally separated from black liquor and converted into tall oil. Tall oil is a valuable by-product for softwood mills and is usually sold to tall oil refineries. However, soap acidulation brings from 3 to 5 kg/ADt of sulfur into the recovery cycle in the form of sulfuric acid (H2SO4). This additional sulfur has to be removed from the recovery cycle and is typically realized by purging the recovery boiler precipitator ash. This in turn requires replacement of lost sodium (Na) with caustic (NaOH). If the purging need is high, this will result in high additional costs. In some cases the mill does not want to invest in soap acidulation partly due to the costs and partly due to the S/Na balance. In some cases precipitator ash purging is not allowed, too.
