Efficient Coke Cooling. Sustainable Energy Recovery

Reliable CDQ Operations Powered by Innovation

Coke Dry Quenching (CDQ) is an advanced and environmentally sustainable process used in modern coke oven plants to cool red-hot coke after carbonization without using water. Instead of conventional wet quenching, CDQ utilizes an inert circulating gas system to recover sensible heat from hot coke and generate steam or electricity, significantly improving energy efficiency and reducing emissions.

CDQ OPERATIONS

Our Coke Dry Quenching (CDQ) operations deliver energy-efficient, environmentally responsible, and high-performance coke cooling solutions for modern steel and metallurgical industries. Designed to replace conventional wet quenching systems, our CDQ facilities recover valuable waste heat while enhancing coke quality, reducing emissions, and improving overall plant efficiency.

CDQ technology cools red-hot coke from coke oven batteries using an inert gas circulation system instead of water, enabling effective heat recovery and clean energy generation. The process significantly lowers environmental impact while supporting sustainable industrial operations.

Our CDQ Operational Capabilities

Hot Coke Handling & Transfer

We manage the safe and efficient transfer of coke from coke oven batteries to the CDQ chamber using automated handling systems designed for continuous and reliable operation.

Dry Quenching Process

Hot coke at approximately 1,000°C is cooled in a sealed chamber through controlled circulation of inert gas, preventing oxidation and maintaining coke integrity.

Waste Heat Recovery

The heat absorbed by the circulating gas is recovered through waste heat boilers to generate high-pressure steam for captive power generation and process utilities, improving overall energy utilization.

Gas Cleaning & Recirculation

Our advanced dust collection and gas purification systems ensure efficient removal of coke dust and particulates before recirculating the inert gas within the closed-loop system.

Automated Monitoring & Process Control

We integrate intelligent automation systems for:

  • Temperature and pressure monitoring
  • Gas flow optimization
  • Steam generation efficiency
  • Operational safety management
  • Predictive maintenance support
