PinolaKraft Soap Technology

The Pinola Technology platform provides kraft pulp mills with a more efficient alternative for handling and processing their kraft soap compared to the traditional and less effective skimming, decantation and homogenisation tanks.

Modern centrifugal separators replace these large volume tanks reducing the process footprint and providing greater energy efficiency within the recovery island. Utilising centrifugal forces for separation achieves a reduced process residence time from days to minutes.

The closed system design improves the kraft pulp mills overall environmental sustainability performance by reducing impact on the local environment.

Pinola technology platform comprises of BLiSS, Black Liquor Soap Separation and TOPP, Tall OIl Production Plant. Together these solutions pro-duce cleaner black liquor, fresher tall oil soap and higher yield and quality crude tall oil.

Tall Oil Production Plant, represents the most modern and efficient Crude Tall Oil production plant available producing the highest quality and yield.

Its advantage lies in the patented dynamic tall oil mixer and dynamic tall oil reactor which greatly increase the efficiency of the acidula-tion and splitting stages. Combined with the high speed centrifugal separator results in CTO yields of greater than 98%.

The fully automated process includes a clean-ing in place system which greatly reduces the operating and maintenance costs compared with other CTO production methods.

Black Liquor Soap Separation, is our patented solution for efficient separation of black liquor from soap and solids producing a clean black liquor with < 1g CTO / kg BL DS and a concen-trated solids free tall oil soap.

A cleaner Black Liquor minimises the load on the recovery boiler and maximises the operabil-ity of the evaporator system. BLiSS produces tall oil soap with 10% more CTO at 60% concentration and free of solids, maximising CTO production while at the same time minimising the consumption of chemicals for splitting and scrubbing.

Kraft Soap Technology

PinolaBLiSS* Black Liquor Soap Separation

The Pinola BLiSS technology replaces exist-ing homogenisation and soap skimming tanks with centrifugal separators, reducing the residence time and plant footprint drastically.

BLiSS reduces scaling problems in the evapo-ration plant and increases the recovery boiler capacity leading to increased chemical recovery.
