How We Make Kraft Pulp

The fibre we use to make kraft pulp is mainly made up of leftovers from British Columbia lumber mills These wood chips and shavings were once considered waste and sent to landfills or burned We match tree species and other pulp characteristics with customers' end-use requirements and control blending and bleaching to exacting specifications

Pulp Mill Wastewater Characteristics and Treatment

The pulp and paper industry consumes enormous amounts of water and natural resources and is also one of the largest effluents generators Before the 1970s wastewaters from the pulp and paper mills were normally discharged directly to the rivers or lakes without any treatment or even a rough primary treatment The high organic loads and solid

Production of Pulp Paper and Board

This BREF covers the processes involved in the production of pulp and paper in integrated pulp and paper mills as well as for non-integrated pulp mills (market pulp) and non-integrated papermills using purchased pulp for paper production The main operations covered are • chemical pulping • kraft (sulphate) pulping • sulphite pulping

Making Paper

THE second chemical method for pulp making was the sulfite process invented by Benjamin C Tilghman who experimented with the effect of sulfurous acid on wood shortly after the Civil War His digester was a rotating horizontal cylinder lined with lead and about 50 feet long by 3 feet in diameter

Cancer incidence among Swedish pulp and paper mill

5/29/2012Associations between various malignancies and work in the pulp and paper industry have been reported but mostly in analyses of mortality rather than incidence We aimed to study cancer incidence by main mill pulping process department and gender in a Swedish cohort of pulp and paper mill workers The cohort (18 113 males and 2 292 females enrolled from 1939 to 1999 with 1 year of

Method for generating heat and electricity in a sulphate

A method and apparatus for generation of electricity by pressurized gasification of black liquor in a combined power plant The gases produced in the gasification of black liquor are purified and introduced into a gas turbine for generating electricity From the turbine the gases are conducted to a waste heat boiler High pressure steam generated in the waste heat boiler and or auxiliary

3/18/2020Sulphate pulp mills normally operate in both integrated and non-integrated modes whereas sulphite pulp mills are normally only integrated – i e part of paper-production chains Mechanical pulping and recycled fibre processing is usually an integrated part of the papermaking but has become a stand alone activity in a few single cases

Kraft process

The kraft process (also known as kraft pulping or sulfate process) is a process for conversion of wood into wood pulp which consists of almost pure cellulose fibers the main component of paper The kraft process entails treatment of wood chips with a hot mixture of water sodium hydroxide (NaOH) and sodium sulfide (Na 2 S) known as white liquor that breaks the bonds that link lignin

Pulp Production

However the lignin from the sulphate and some sulphite processes can be burnt as a fuel oil substitute In modern mills recovery boiler operations and the controlled burning of bark and other residues makes the chemical pulp mill a net energy producer which can often supply power to the grid or steam to local domestic heating plants
