Dear Dr Amajirionwu -

I wish to submit additional information to support an application under the BAT licence review (POO30-05) to increase the gas volume in Kiln 3 at Platin Works. The proposed increase in gas volume is in the context of the existing Kiln 3 configuration w.r:t. to site layout, fuel inputs etc. and is consistent with efficiencies and optimization of kiln systems as outlined in BAT #7, BAT #10 and BAT #19 of the Cement BAT conclusions.
I \
Or. Peter Rosholm, FL Smidth, has prepared a report on behalf of Irish Cement which outlines the improvement in clinker production (tonne per day) and the associated energy saving (kcal per kg of clinker) benefit that an increase in Kiln 3 gas volume to 477,878 Nm3/hr (from the existing limit of 410,000Nm3/hrj could achieve. A copy of the report is attached for reference.
I
I Background :
A" review of the BAT conclusions for the cement industry was undertaken, following a request from the EPA. It was determined that the existing Kiln 3 system can be optimized by increasing kiln gas flow to achieve an increase in clinker production with a higher energy efficiency. The following BAT conditions were reviewed in this context:

BAT 7: In order to reduce /minimise electrical energy consumption, BAT is to use one or a combination of the following techniques: ai Applying improved and optimised kiln systems and a 'smooth and stable *kiln process ...

BAT 10: In order to reduce / minimise electrical energy consumption, BAT is to U
one or a combination of the following techniques: e. Process control optimisation
A table outlining the benefits of process control optimization (the increase gas flow) as summarised from the FL Smidth report attached is given as follows:
i
As can be seen above the increase in Kiln 3 gas volume to 477,878 Nm3 / hr yields an increase of 1,250 t of clinker per day, whidh annualised could yield up to an increase of ca. 400,000 tonnes of clinker per year.
The decrease in specific heat consumption a t 5,000 t clinker per 24 hr. compared to ~
3750 t clinker per 24 hr. is due to the relative reduction in kiln' radiation losses a t the i , higher production. The improvement in specific heat consumption is 11 kcal / kg clinker or 11,000 kcal / t clinker. This equates to a saving of 12.8 kWh / t clinker (1 ,I kcal = 0.00116 kWh). The World Business Council for Sustainable Development ; (WBCSD) describes in its CO2 protocol that the CO2 per power unit produced 1 externally is 0.43 kg CO2 / kWh. Therefore the energy saving can be also be expressed as a reduction of 5.5 kg of CO2 per tonne of clinker produced a t the higher ' gas volume.
In the context of optimizing the process by increasing Kiln 3 gas volume, a review of air emissions w.r.t BAT #19 from the Cement BAT conclusions was undertaken.
BAT 19: In order to reduce emissions of NOx from the flue-gases of kiln firing and/or '1 reheating/precalcinating processes, BAT is to use one or a combination of the following techniques:

a. Process optimisation
In the table below the Kiln 3 NO, emission (kg / t clinker) is calculated for the current 'I and proposed scenarios. As can be seen in the table below there is a reduction in the NO, emission rate for the current and proposed gas volumes of the order of 0.01 Kg !I NO, / t clinker. Based on this it is expected that similar reductions will be achieve3 1

A report has been prepared by Dr. Peter Rosholm on behalf of Irish Cement which outlines the improvement in clinker production (1250 clinker tonne per day) and the a$sociated improvement in energy efficiency (11 kcal per kg of clinker) that an increase in Kiln 3 gas volume to 477,878 Nm3/hr could achieve.
Additionally, it has been demonstrated that with the increase in Kiln 3 gas volume the emission rate of NO, in terms of kg NO,/ t clinker is reduced. Based on this it is expected that similar reductions will be achieved for other ELVs (particulate, SO, etc.). Air dispersion modelling of emissions of NO, and other pollutants a t much higher flow rates has been previously submitted. The air dispersion modelling has shown that Air Quality Standards and Guidelines are easily met in respect of all regulated substances.

q n this basis, Irish Cement is seeking an increase in the volumetric flow rate limit of k l n 3 from 410,000Nm3/hr to 477,878 Nm3/hr. Irish Cement is not applying for a cpange t o the volumetric flow rate limits for Kiln 2 and Cement Mill 1 at this time.
I trust that the above addresses the queries raised. Should you need any further !
information please don't hesitate to contact the undersigned.

Production simulation a t 3750 and 5000 tpd clinker - estlmatlon of PH exit gas In
6tack expressed as Nm'/h (dry) gas 6 10% 0 2 .
.
Kiln 3 a t Ir ish Cement Platin works is currently producing around 3750 tpd clinker with less than 410000 Nm3 (dry)/h@'lO% 0 2 preheater exit gas in the stack. Due to increased market demand Irish cement is con- sidering increasing the production capacity of kiln 3 at Platin Cement works. The maximum achievable production capacity is evaluated to be around 500.0 tpd cligker.
The operational parameters of kiln 3 at Platin Cement work have been simulated at 2 different production levels for worst case fuel scenario. The simulations are shown in:
0 Enclosure 1: simulation of the operational parameters at a produc- tion capacity of 3750 tpd clinker.
0 Enclosure 2: Simulation of the operational parametek at a produc- tion ca.pacity of 5000 tpd clinker.
3750 <tDddinker 'ienclosure 11 c
The simulation shows a specific heat consumption on 860 kcal/kg clinker.
The preheater exit gas is simulated to 2.498 kg gas/kg clinker with a density of 1.352 kg/Nm3 corresponding to 1.848 Nm3 (wet) gasjkg clinker with a moisture content of 0.110 kg HzO/kg dry gas.
The amount of dry preheater gas is calculated as 2.498/1.11 = 2.250 kg dry gas/kg clinker.
The amount of moisture in the preheater exit gas is calculated to 2.498- 2.250=0.248 kg HzO/kg clinker or 0.310 Nm3/kg clinker and the volume of dry preheater gas is calculated to 1.848 - 0.310 =1.538 Nm3 dry gas/kg clinker with 4.4% 0 2 , 27.8% CO2 and 67.8% N2.

T i e simulation shows a specific heat consumption on 849 kcal/kg I cli,nker., 1
i i The decrease in specific heat consumption at 5000 tpd clinker compared to,at 3750 tpd clinker is due to the relative reduction in kiln radiation losses a t the higher production.

The amount of moisture in the preheater exit gas is calculated to 2.471- 2.226=0.245 kg HzO/kg clinker or 0.306 Nm3/kg clinker and the volume of dry preheater gas is calculated to 1.826 - 0.306=1.520 Nm3 dry gas/kg clinker with 4.4% 0 2 , 28.0% CO2 and 67.6% N2.
