The document discusses the paper and pulp industry. It describes the key manufacturing steps including timber collection, de-barking, chipping, chemical and mechanical pulping processes, refining, and papermaking. It also discusses the treatment of waste from pulp mills. Effluents from pulp and paper mills contain high levels of solids, COD, BOD, color, and other pollutants. Treatment methods include screening, sedimentation, and biological treatments like anaerobic technology to break down organic pollutants.
The environmental impact of paper is significant, which has led to changes in industry and behavior at both business and personal levels. With the use of modern technology such as the printing press and the highly mechanized harvesting of wood, disposable paper has become a cheap commodity. This has led to a high level of consumption and waste. With the rise in environmental awareness due to the lobbying by environmental organizations and with increased government regulation there is now a trend towards sustainability in the pulp and paper industry.

Pulp and Paper Industry (Pulp Mill, Paper Mill, Printing and Writing Papers, ...Ajjay Kumar Gupta
Pulp and paper are manufactured from raw materials containing cellulose fibers, generally wood, recycled paper, and agricultural residues. In developing countries, about 60% of cellulose fibers originate from non wood raw materials such as bagasse, cereal straw, bamboo, reeds, esparto grass, jute, flax, and sisal. The main steps in pulp and paper manufacturing are: Raw material preparation and handling, Pulp manufacturing, Pulp Washing and Screening, Chemical recovery, Bleaching, Stock Preparation, and Papermaking.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.

3. INTRODUCTION
THE PAPER INDUSTRY PLAYS A VERY PROMINENT ROLE IN THE WORLD
ECONOMY.
THE PULP AND PAPER INDUSTRY CONVERTS WOOD OR RECYCLED FIBRE INTO
PULP AND PRIMARY FORMS OF PAPER.
IN THE 1800S, THERE WAS A SHIFT AWAY FROM USING COTTON RAGS FOR
PAPER PRODUCTION. BUT LATER WOOD BECAME THE MOST IMPORTANT
SOURCE OF FIBER.
FIRST MECHANICAL AND THEN CHEMICAL METHODS HAVE BEEN DEVELOPED
TO PRODUCE PULP FROM WOOD.
4. PULP AND PAPER MILLS
Pulp mills separate the fibres of wood or from other materials,
such as rags, wastepaper or straw in order to create pulp.
Paper mills primarily are engaged in manufacturing paper from
wood pulp and other fibre pulp

7. Timber
Timber used for
papermaking comes from
well managed forests
where more trees are
planted than harvested to
ensure sustainable growth.
8. De-Barker
Bark is stripped from
the logs by knife,
drum, abrasion, or
hydraulic barker. The
stripped bark is then
used for fuel or as soil
enrichment.

9. CHIPPING
Stripped logs or timber are
chipped into small pieces
by knives mounted in
massive chipping machine
.
chips are then stored in
huge bins ready for the
next process.
CHIPPING MACHINE
10. CHEMICAL PULPING PROCESS
Chips from the storage bins are fed
into a digester. The woodchips are
then 'cooked' to remove lignin.
Lignin is the binding material which
holds the cellulose fibres together.
The chemical process is energy self-
sufficient as nearly all by-products
can be used to fire the pulp mill
power plant.
11. MECHANICAL PULPING PROCESS
MECHANICAL PULP YIELDS OVER 90% OF THE WOOD AS FIBER IS PRODUCED BY FORCING
DEBARKED LOGS, ABOUT TWO METERS LONG, AND HOT WATER BETWEEN ENORMOUS
ROTATING STEEL DISCS WITH TEETH THAT LITERALLY TEAR THE WOOD APART
12. HYDRAPULPER
THE WOOD FIBRES ARE BROUGHT
INTO A CIRCULAR TANK
CONTAINING WATER .
THIS HAS A VERY POWERFUL
AGITATOR AT THE BOTTOM
WHICH BREAKS UP THE BALES
(WOODEN FIBRES) INTO SMALL
PIECES.
13. BLEND CHEST
CHEMICALS CAN BE ADDED TO OBTAIN THE
REQUIRED CHARACTERISTICS TO THE
FINISHED PAPER.
DYES ARE ALSO ADDED , aS NECESSARY , tO
COLOR THE PAPER
14. WASTE PAPER
Waste paper is collected from Waste Paper Banks and Commercial dumps.
Waste paper currently represents 67% of the raw material in paper industry.
Paper not suitable for recycling is removed.
15. DE-INKING
BEFORE PRINTED PAPER CAN BE RECYCLED THE
INK NEEDS TO BE REMOVED, OTHERWISE IT WILL
BE DISPERSED INTO THE PULP.
THERE ARE TWO MAIN PROCESSES FOR DE-
INKING WASTE PAPER –
WASHING
FLOTATION .
16. SCREENING AND CLEANING
Pulps contain undesirable fibrous and non-fibrous
materials, which should be removed before the pulp is
made into paper .
Cleaning involves removing small particles of dirt and
grit using rotating screens and centrifugal cleaners.
REFINING
This is where the cellulose fibers pass through a
refining process which is vital in the art of
papermaking. Before refining, the fibers are stiff,
inflexible and form few bonds.
17. PAPERMAKING MACHINE
A SLURRY OF FIBRE (USUALLY WOOD OR OTHER VEGETABLE FIBRES) IS DRAINED TO CREATE
A CONTINUOUS PAPER WEB. AFTER THE FORMING SECTION THE WET WEB PASSES
THROUGH A PRESS SECTION TO SQUEEZE OUT EXCESS WATER, THEN THE PRESSED WEB
PASSES THROUGH A HEATED DRYING SECTION.
19. PULP AND PAPER INDUSTRY
• Use wood ad raw material to produce paper,
pulp, board and other cellulose based
products.
• Bagase, hemp, straw are also used
• Composition of the pollutants in the effluent
depends on the raw material used.
20. EFFLUENTS
• Waste water- 60 m³/ tonne of
paper produced
• Contain solids and dissolved
matter.
• Potentially very polluting
• COD as high as 11000mg/l
21. SOURCE EFFLUENT CHARACTERISTICS
Water used in wood handling/
debarking
Solids, BOD, color
Chip digester and liquid evaporator
concentrate
Concentrated BOD, can contain
reduced sulphur
“white waters” from pulp screening,
thickening and cleaning
Suspended solids, can have
significant BOD
Bleach plant washer filtrates BOD, color, chlorinated organic
compounds
Paper machine water flows Solids, often precipitated for reuse
Fiber and liquor spills Solids, BOD, color

COD 3400-5780 716
BOD 680-1250 155
COD/BOD 3.9-5 4.6
24. SCREENING
• Screens- to remove course, bulky and fibrous components
from effluents
• Grid chambers and settling tanks are used
• Efficiency of screening depends on the spacing between
screen bars
- fine screening, spacing < 10mm
-mediun screening, spacing 10-40mm
- coarse screening, spacing > 40mm
25. SEDIMENTATION
• Using gravity to remove suspended solids from water.
• Removal of suspended particles by sedimentation depends on size and
specific gravity of the particles.
• Sedimentation tanks are used
• Settled sludge is removed
• High efficiency is achieved in the subsequent treatment processes.
26. BIOLOGICAL TREATMENT
• Degrade pollutants dissolved in effluents by the action of
microorganisms.
• Pollutants are used as nutrients
• Microorganisms use these pollutants to live and reproduce.
27. ANAEROBIC TENCHNOLOGY
• Effluents originating from recycle paper mills
• Effluents from mechanical pulping (peroxide bleached), semi-chemical
pulping, sulphite and kraft evaporator concentrates
• Bacterial hydrolysis of input materials to break down insoluble
organic polymers
