Brief System Description
The thermoplastics manufacturer proposed to use a Silo(10mX30m) to store the produced
plastic powder which has been separated through a cyclone.
Design Intention
To design an Explosion Vent for the proposed silo with a scenario of dust explosion inside the
vessel and subsequently duct the contents to safe area(>15m).
Schematic Diagram
Design Approach with Calculations and Justified AssumptionsAssumption: The venting of single enclosure is only considered and linked cyclone is treated as a
separate entity as the unit is separated by appropriate isolation devices (rapid action valve) &
“designed” rotary valve to mitigate eventualities.
Material of Construction: Stainless Steel
Dust specific Deflagration Index Kst, which denotes explosibility characteristic, is calculated using cube
root law as:

Vent Sizing using VDI 3673 Approach
Effect of Vent Duct on Pred
It is presumed that vent products are of toxic nature and need to vented to >15m.
With a consideration of Factor of Safety,Length of vent duct,l = 16m.
Kst- Nomograph method cannot be used as vessel volume>1000m3
With consideration elongated vessel (H/D>1),
Design Pressure Alteration-Proposals with Justification
As calculated above PIred,max has distinct disproportion with envisaged design pressure Pred i.e.
0.25barg,and the enclosure will not be capable to withstand the pressure surge. As vessel is located in a
congested area,the toxic vent products need to be vented to >15m, for that reason, P Ired,max cannot be
altered.
Incisive proposal is to alter the design pressure of silo which is at design stage to 1.90 barg which is greater than PIred,max(1.66barg).
New Design Pressure, Pred,max = 1.90 barg
Validity Check for using VDI 3673 Equation
Assumption& Justification: The dust cloud is assumed to be homogeneous nature so as to design an
effective vent area considering worst case scenario.Inhomogeneous dust distribution was not
considered since equation should adhere to strict boundary conditions and for this case under
study,reliable confirmation was not available.
Uniform distribution of dust cloud in the vessel.(Voldustcloud= Volvessel).
Unimpeded progress of flame front from point of ignition to vent (i.e.no internal obstructions).
Pred depends on cross section of vent and not on any internal obstructions.
Pmax =9 bar for a St2 dust(Perry,2008)

Thus applying VDI equation for homogenous dust distribution,
Vent Duct Design
The duct selected is of circular type with straight horizontal venting due to better air tightness,
higher strength for material of same gauge and for limiting overhead dust accumulation.
Considering Vent Area=Duct Area;Vent Area, Av=17.78m2
The diameter of the circular duct,A=(4XAv/π)1/2 = 4.76m
Length of the duct=16m

2)
The entire storage and filling process need to be systematically analyzed and appraised to
augment process safety and reliability of the entire unit.The multiplicity of activities carried out in the
unit inherently possess substantial risks which should be countered in a methodical manner.
Overall Safety Management-Silo and Filling System
Elimination Elimination is a prudent technique to evade needless risks of the activity.The system should be
thoroughly analyzed from onset to make it inherently safer to avoid a dust explosion.The scale up team
can consider measures such as:
● Hazardous materials inventory reduction to suit the necessity.The design decision to build a
big(V=~2500m3) silo for an inter-mediatory storage should be reevaluated to assimilate the
tangible process requirement, and subsequently optimize the storage size.
Removal of unwanted interconnections(to prevent flame propagation in case of a mishap).
Reduction of pipe length to as low as reasonably required.
Judicious Plant Layout and hazardous activity segregation(minimize congestion). Installation of state-of-the-art instrumentation systems which could accommodate error
tolerances and avoid human intervention.eg:online monitoring electrical field inside silo.
Consideration of particle size and its influence on F&E characteristics.
Optimize process parameters like temperature,mass flow rate,pressure etc.
Moisture control in silos and powder handling sections
Substitution
Measures to be configured to substitute the activities/processes to reduce imminent
risks of the unit as a whole like.
Use of less hazardous materials in the process line.The use of a powder with Kst=252barms-1 and
St2 could be reevaluated and if possible substituted.
Use of circular dust instead of rectangular one to minimize dust accumulation. Substituting N2 gas instead on air for pneumatic conveying.
Alternative safe process route avoiding dust handling in slurry form rather than fine dust form.
Substituting carcinogenic MDA from the process stream.
Administrative& Procedural Controls:Formulation of SOPs,Fool proof PTW system,robust maintenance
procedures,Selection of competent personnel,On-Job-Training,Work-Rest Regime,Procedural
Controls,Specialist competency skills,Implementation of 5S principles of housekeeping,workplace
exposure assessment,inspection system for checking dust deposits inside pipelines.
Personal protective Equipments: PPEs should not be considered as primary BoS.All appropriate PPEs to
be adequately donned by the concerned operatives.
Housekeeping Strategy
A well structured housekeeping stratagem needs to be promulgated to control the dust layerdeposits in the plant.All plant and equipment area including beams,rafters,conduits,light fixtures,ceiling
etc must be rigorously cleaned and periodically inspected to prevent dust accumulation.Use vacuuming
devices to suitably clean the dust in all areas(visible as well as conceivable).

The main hazard associated with this particular unit is that of a probability of dust fire and
explosion emanated out of powder handling systems of the unit.
The knowledge of elements of a dust explosion lead us to the required explosion prevention and
protection measures.
Dust Explosion Prevention StratagemAvoidance of Ignition Sources
Complete avoidance of ignition sources (esp. unconcealed) is not practically feasible, but good
design&judicious practices could certainly reduce probability of an ignition.Zoning studies should be
carried out to classify hazardous areas(Zone20,21,22) and accordingly,suitable electrical equipments to
be selected.To summarize, the ignition sources usually encountered in a powder processing plant and its
precautionary measures are:

Inerting
Inerting could be a valid BoS especially in a typical process stream containing pneumatic
conveyors,cyclones and silos.The inerting method could be a)Addition of inert dust b)Purging with inertgases to reduce vapour concentration below LOC,latter the appropriate method in this particular case.
The inert gas selected could be N2,flue gas,steam,argon,helium or CO2,preferably the former
one. The inert gas in the stream would tangibly lower the LOC(6-13% with N2,but advised to carry out a
specific test) and prevent development of flammable dust-oxidant formation(Barton,2002).Various
purging techniques like pressure,vaccum or flow through purging should be judiciously selected and
employed.An oxygen sensor with alarm in the stream is also recommended.The flammability diagram

could be employed when the inert gas is introduced into the process stream and is considered to be
BoS.
Ventilation
In the powder handling plant, Local Exhaust Ventilation with apposite rate of air changes
capable of preventing formation of flammable dust-oxidant concentration in the processing area should
be installed.Bag filling station is a potential area where dust clouds could be developed.
Dust Explosion Protection StratagemExplosion Containment
The vessels could be built to withstand pressure surge of a dust explosion causing inside
vessels and thereby avert catastrophic structural failure.Since the project is in design stage and vent
products is envisaged to be of toxic nature,it would be much easier to assimilate these ideals into
equipment design.The constructional measures should be correlated with Pmax value.The two modes of
explosion containment options are:
Explosion Suppression
Explosion Suppression could be also used in this case as the products to be vented out is of toxic nature.It is proposed to couple an explosion suppression system(which effectively reduces
fireball diameter),isolation system together with the venting system,thereby minimizing the impact
on long discharge vent duct(16m).The principle is to detect the explosion at incipient stage and to
suppress the fire ball with rapid injection(within milliseconds) of suitable suppressants and thereby
reduce Pred,max.The proposed suppressant system specifications for the project is:
Explosion Isolation
Explosion Isolation techniques are required to separate propagating flame front from
reaching other “safe” process streams.Explosion Isolations techniques are to be coupled with various
explosion prevention systems.The various options recommended are: Rapid Action Valve(RAV):- RAV could be installed in pipelines to prevent explosion progression
to downstream.RAV(with response time<25ms) is proposed to be provided every 5m over the entire
stretch of pneumatic convey stream to timely isolate the flame front from “safe” areas.The combination
of pressure&optical detectors to be used.
Extinguishing Barriers:- Suppressant barriers activated by coupled optical flame detector should
be installed every 5m in pneumatic convey stream, which inject an inert suppressant and thereby
impede flame progression.
Rotary Valves:-Rotary Valves are used to prevent flame propagation by the principle of
quenching the flame by making its progression route through “small” gaps.Depending upon the
explosibility characteristics of the specific dust, “gap length” could be decided.In case of an explosion
inside silo,the rotary valve installed will prevent flame progression to the cyclone.
Explosion Relief Venting
All enclosures are treated as separate entities and adequately designed explosion vents are
provided in all linked vessels in the process stream like cyclone,pipelines,dust collectors etc in addition
to well engineered vent in silo

Introduction
The innate environmental hazards associated with thermoplastics manufacturing and
ancillary activities of this manufacturing unit would cause detrimental or irrevocable effects to the
environment,if not,approached,managed and controlled in a scrupulous way.To construct an effectual
environmental management system,it is imperative to run in parallel with current regulatory
requirements which helps to structure out environmental sustainability.
Drawing Parallels- (Environmental Impact) vs.(Legislations&Best Practices)
The law clearly elucidates that it is manufacturers’ responsibility to work out the pollution
control stratagem. The cumulative impact of the thermoplastic industry on surrounding environment
could be broadly delineated as to the detrimental effects on air,water&land.The extent of damage could
span from superficial damage to surroundings to far-reaching damage to flora and fauna in a distinctive
measurable scale.The thermoplastics industry uses 4,4’Methylenedianiline as an additive en-route of the
process which is identified as a polluting agent of aquatic environment(R51/53).The innate
environmental risks, characteristic to complex process and operations of a chemical manufacturing unit,
could also extend their wings of damage to surrounding ecological stratum.
The industrial activity should be well analyzed in perspective of harmful effects it can induceto our vicinity.The initial step is to analyze whether it falls into an MAH site as per COMAH 1999
Regulations.COMAH 2005 Amendments Schedule 1-Part3 necessitates stringent environmental
regulatory controls for the use of R51/53 chemicals like MDA. If the quantity exceeds threshold quantity,
the unit should be appropriately classified (Lower Tier or Top Tier) and associated regulatory obligations
should be promptly demonstrated.The detail analysis of harmful properties of individual chemicals need
to carried out and compared with table and, if applicable use the aggregate rules in threshold quantity
summation. An Environmental Policy needs to be formulated in line with COMAH addressing specifically
the ideals and methodology for major environmental accident prevention.The environmental risks could
be elucidated by The Source-Pathway-Receptor model promulgated in COMAH.
The “siting” of the facility to be critically analyzed in perspective of damage it induces to
neighboring ecological distribution.Proactive corrective actions should be undertaken to limit the
environmental disturbance.eg:Since a R51/53 chemical is stored,it is highly advisable to locate the
industry well away from a potential receptive aquatic environment(eg:river,pond etc).
In line with COMAH Regulations,a Safety Report should be addressed to concerned authority
elucidating the site location,topography,chemicals,compostions&quantities,different modes of
release,pathway of hazard propagation,potential receptive environments,potential receptors like red
data book species etc.A Qualitative and Quantitative modeling including EHI should be undertaken to
reveal all foreseeable hazards.The hazard should be further scrutinized to classify whether it is potential
MATTE.eg:If potential MDA release to the river stream could cause the death to red book data species, it
should be considered as a MATTE.
Environmental Permit should be applied appropriately in accordance with Environmental
Permitting(England&Wales) Regulations2010 and a valid permit(standard/bespoke) shall be obtained
prior to start up of the unit.Environmental Permit covers mandatory regulatory requisites and bestpractices that need to be integrated into the“regulated” facility.The appropriate regulator to be decided
as per installation categorization(PartA1/PartA2/PartB).
Noise pollution could also be caused due to equipment functioning,if sound level > 85dBA.
In consensus with ISO14001 system(EMS),the development of an environment register
covering Aspects-Impacts is the next vital rung in the impact assessment.It would help to systematically
classify and record impact of various activities of the process.
A more “generalized”Aspect-Impact-Legal resister of the manufacturing process is developed.

Conclusion
The recognition of foreseeable environmental risks and its proactive mitigation is a pivotal
step for sustainable development.The dynamic balance between industrial progression and
environmental sustainability should be ensured during all phases of the plant life.Comprehensive
quantitative modeling and EIA studies should be carried out for this plant as it will help us to
methodically capture all potential hazards, and to subsequently instigate relevant control measures.Thecorrective measures should be drawn on lines of rigorous regulatory requisites as well as global best
environmental practices.
It is much easier to conceive and adopt changes at the design phase and modulate process &
manufacturing trajectories to tune up with sustainable objectives. This ensures the fulfillment of
company’s long terms objectives and propels the smooth sail towards various target pinnacles.
