- POSCO E&C contracted thyssenkrupp Uhde to design and supply a low‑emission top‑charge coke oven battery as a pad‑up rebuild replacing 1980s Battery #3A at POSCO Pohang, including engineering, equipment, site supervision and commissioning
- Project will install EnviBAT single‑chamber pressure regulation to prevent pressure peaks and minimize emissions; EnviBAT is in operation on more than 30 batteries and over 2,100 ovens worldwide
- Order includes a state‑of‑the‑art MonoClaus plant to replace outdated two‑stage Claus units for sulfur recovery
- Scope also covers a new emission‑free tar separation plant to modernize tar handling and reduce off‑gas emissions
Project overview
POSCO E&C awarded thyssenkrupp Uhde a contract to design and supply a low‑emission, top‑charge coke oven battery to replace Battery #3A at the POSCO Pohang Steelworks; the existing 1980s battery will be shut down as part of POSCO’s coke‑plant modernization program.
Scope and deliverables
The order covers technology provision, engineering, equipment procurement, site supervision and commissioning support; it includes replacement of two‑stage Claus units with a MonoClaus plant and installation of a new emission‑free tar separation plant to modernize tar handling and sulfur recovery.
Emissions control technology
The battery design incorporates EnviBAT single‑chamber pressure regulation for continuous pressure monitoring and adjustment throughout the coking cycle to prevent early pressure peaks and minimize emissions via oven doors and the battery roof; additional measures cited include flexible spring‑loaded door systems and water‑filled rising pipe covers. EnviBAT is reported to be in operation on more than 30 batteries and over 2,100 ovens worldwide.
Partnership
POSCO E&C and thyssenkrupp Uhde will collaborate on the pad‑up rebuild, leveraging their engineering and site execution roles for the project.
