boiler for pulp - sweetgiants.be

Black liquor - Wikipedia. Early kraft pulp mills discharged black liquor to watercourses. Black liquor is quite toxic to aquatic life, and causes a very dark caramel color in the water. The invention of the recovery boiler by G.H. Tomlinson in the early 1930s, was a milestone in the advancement of the kraft process. Learn More

Black Liquor Treatment for Pulp Mills - Water Online

Using a nanofiltration module in the system is a commercially-viable option for treatment of black liquor. Nearly 80 to 90% of the feed black liquor is recovered as water suit-for reuse or discharge, while less than 10 to 20% is fed to the evaporator as concentrate, thereby greatly reducing the load to the evaporators.

4-4 Recovery Boiler Chemical Principles

A black liquor recovery boiler has two main functions. On one hand, it generates steam from the heat energy liberated upon combustion of the organic constituents of black liquor burned in the boiler, whereby the recovery boiler serves as a steam boiler. On the other hand, the chemicals from pulp digesting - sulphur and sodium - are recovered

Black Liquor Gasification | Industrial Efficiency

Black liquor, which accounts for the majority of the fuel consumed in Kraft mills, is usually combusted in recovery boilers to recovery chemicals and to produce process steam and on-site electricity (via a steam turbine). The efficiency of such boilers is, however, low (around 65-70%). Black liquor gasification is a process in which a clean synthesis gas (syngas) is produced from black liquor

Black Liquor Gasification | netl.doe.gov

The black liquor is typically 15-20% solids by weight and these so-called "black liquor solids" contain about half the energy of the original woodchips. The older method to recover this energy involved concentrating the solution to about 75-80% solids by weight and then burning in a recovery boiler to generate steam.
