Pinola BLiSS

Pinola Bliss, Black Liquor Soap Separation is a patented process developed by Head Engineering AB under the name of Pinola BLiSS. It is designed to efficiently separating clean Black Liquor from soap and solids that produces clean black liquor. The Pinola process produces a clean black liquor with <1gm CTO/kg Black Liquor free from concentrated solid free tall oil soap. This technology replaces existing homogenisation and soap skimming tanks with centrifugal separators, reducing the residence time and plant footprint drastically. BLiSS reduces scaling problems in the evaporation plant and increases the recovery boiler capacity leading to increased chemical recovery.
