ANDRITZ pre-hydrolysis cooking for dissolving pulp production
The key to dissolving pulp production is efficient removal and recovery of hemi-cellulose from the fiber source. The pre-hydrolysis vessel (PHV) from ANDRITZ is a new technology developed for cost effective production of high quality pulp and valuable by-products.
The challenge
In the production of dissolving pulp, there are unique challenges for hemi-cellulose removal with continuous cooking. Stable production and the precipitation of by-products from the chemical reaction were common difficulties in traditional systems.
The solution
ANDRITZ has re-designed the cooking process to include auto-hydrolysis for efficient hemi-cellulose removal. The process design and technology components are based on experience in paper grade pulping and they eliminate instabilities in previous systems. The design can be easily applied to existing installations.
