Latest Patents

One of his latest patents is titled "Method for generation of clean steam in a continuous digester system." This invention relates to an enhanced method for generating clean steam in a digester plant of a chemical pulp mill. By utilizing a steam-to-steam converter (SSC) fed with venting steam from a black liquor flash tank (FT) and venting steam from chip steaming (SV), the volume of clean steam produced can be increased by over 40-50%. This improvement ensures that the clean steam generated meets the needs for preheating chips in the digester system, even under severe operational conditions. Additionally, the total consumption of clean steam from the mill's steam net can be reduced, allowing for its use in other applications such as electricity production, thereby contributing to the transformation of the pulp mill into an environmentally friendly facility.

Another patent by Ljungkvist is "Apparatus and method for permeability measurement." This invention further showcases his innovative approach to enhancing industrial processes.
