Future Standards: Future Standards: Minimizing or eliminating battery operating delays will lower coke ovens emissions. The Stelco Hamilton Works coke ovens department has a broadened preventive maintenance and upgrade plan to meet all future standards.

slide-16
SLIDE 16

Upgrades Upgrades

  • Rebuilding #3 primary cooler

aiding in improving gas quality.

  • Extending the battery decking

to increase coal bunker usage.

  • Rebuilding #3 tar decanter to

remove more tar.

  • Adding another oxygen sensor

into the rich gas stream to control under firing usage.

  • Designing a one spot quench

car to assist the coke shed pushing emission control.

  • Engineering study to resurrect

the #5 & #6 boosters to eliminate the need for #1 coke

  • ven gas flare.

Benzene Monitoring Program Benzene Monitoring Program

  • Monitor – Hand-held with Photoionization Detector for VOCs (specific

for benzene)

  • Most of the sources at the Coke Ovens and By-Products are well

controlled

  • Sources with opportunities for improvement include:
  • Group 1

Group 1 – Manage with procedures and operating practice

  • Fugitive Battery emissions – charging, doors (minimize visible

leaks)

  • Light Oil Loading hose – (upon completion of loading, cap off hose)
  • Keep hatch closed– Dissolved Air Clarifier; Excess Ammonia Liquor

Storage Tank – (work practice – reinforce operators to close hatches and maintain seals)

  • Group 2

Group 2 – Emission control equipment

  • Process Water Decanter Tank

– (emission control to be incorporated at top vent on the tank)

  • Next steps: Implementation of identified opportunities for improvement

Jan 1 – Feb 28, 2019 Operational Adjustments

  • Increased coking time; increased coke oven gas supply

to underfiring; decrease coal moisture

Emission Observation (March 12, 2019) Emission Observation (March 12, 2019)

Conclusion:

  • Pushing emission

Probable Cause:

  • Low oven temperature due to water washing of the

underfiring system to remove deposits in the piping

  • The gas to the oven being water washed is shut off as the

washing is being done Resolution:

  • The Battery heating was supplemented by natural gas

Batch Anneal Batch Anneal

  • Upgrade existing #3 Batch Anneal facility
  • 12 bell anneal workbases (6 for heating; 6 for cooling)
  • Anneal steel coils in nitrogen atmosphere
  • Expected annual production of approximately 540,000 tonnes of

annealed steel coils

  • Stelco has applied for a new Environmental Compliance Approval for

non-contact cooling water system

  • Existing baywater supply network to control temperature of cooling

bell inner cores

  • Non-contact cooling water to be discharged through an existing

industrial sewer to Hamilton Harbour via MISA control point

  • Water from existing baywater supply network to a closed loop

cooling water skid

  • Effluent water quality should be equivalent to influent
  • Effluent temperature to be monitored by thermocouple; if required,

would be regulated prior to industrial sewer outfall
