BEHAVIOUR OF TRACE ELEMENTS

COMPONENTS in RDF: Behaviour in the Pyro-Process

Elements involved Components/ Carriers Transfer Details

Chrome, Zinc, Nickel,

Arsenic, Vanadium, etc.,

Sulfur from the fuel

Clinker mineral elements,

Low volatile metals

Sulfur component of fuel

Hardly volatile: mainly transfer into the clinker

TOC, Lead, Mercury

Sulfur from raw meal

Non burnt organics,

Products of combustion

Volatile: Mainly transfer into the preheater exhaust

gas

Thallium, Cadmium, Mercury Volatile trace metals

Linked to dust particles

Volatile: Likely build up of internal cycles.

Transfer into preheater exhaust dust, cycle builds

until overflow is picked up at filter and recirculated via

raw meal. Mixing filter dust to cement bleeds cycle.

Chlorine,

Sodium, Potassium

Halogens, alkalis,

residuals conveyed with

clinker

Build up of internal cycles likely:

By-pass system can bleed elements to external

disposal.

ENVIRONMENT

A TEC > Dealing with more Chlorine / 11 ATEC/JF: Confidential Information

Dealing with More Chlorine

Tratando con más Cloruro

A TEC > Dealing with more Chlorine / 2

REASONS FOR USING A BYPASS IN THE CEMENT INDUSTRY

Raw meal which have high contents of chlorine,

alkalis and sulphur

Using a high amount of alternative fuels

containing chlorine & sulphur

Build ups and heavy coating in the area of the

kiln riser duct and meal pipe to the kiln

Strict environmental regulations


GAS TAKE OFF DUCT

Main Advantages:

Big take off area

Low take off velocity

Particles < 10 µm

• No cyclones needed

• Gas can be used for raw meal

drying to reduce thermal losses


QUENCHING CHAMBER

Made completely of metal

(no lining required)

Cooling in 1 step to 200 C

Minimum space requirement

Simple & trustworthy operation

Performance Test Result

• Cl in bypass dust 14%

• Cl in dust return to hot meal chutes 3.5%

• Cl in raw materials 0.0083%, clinker basis

• Gas flow at kiln inlet approx. 80,000 Nm3/hr

• Bypass % of gas flow at kiln inlet 8 %

• Dust in gas at input to quench chamber 0.25 kg/Nm3

• Dust to quench chamber 38 te/day

• Dust out of quench chamber (including KCl) 45 te/day

• Dust to waste 22.5 te/day

• Dust return to hot meal chute 22.5 te/day


Operational Results Today

Operation Period since start up: 30 months

Total unscheduled maintenance: insignificant

Total bypass dust saved from depositing: approx. 20‘000 tons

Total waste utilised for alternative fuel: approx. 165‘000 tons

Chloride in bypass dust: average 12% to 16%
