At the JISCO project site, the Primary Gas Cooler (PGC) A Tower has successfully completed the lifting and positioning of its first heat-exchange section, marking a key milestone in the installation of the initial cooling system for coke oven gas.

As a primary gas cooler manufacturer, our focus goes far beyond the lifting operation itself. The PGC is the first and most critical cooling stage in the coking process, where raw coke oven gas undergoes initial temperature reduction. Its performance directly affects downstream gas purification, operational stability, and overall plant efficiency.

The installed tower features a robust structural design and a well-engineered heat-exchange configuration, balancing high heat-transfer efficiency, low pressure drop, corrosion resistance, and long-term operational reliability. Every aspect—from material selection to fabrication details—has been optimized to withstand continuous operation under demanding industrial conditions while allowing for maintenance accessibility.

The lifting was carried out using a 750-ton heavy-duty crane, a machine proven in multiple high-precision projects, including aerospace ground support. While this highlights the strict requirements for accuracy and safety on site, the real confidence comes from the equipment itself—sound design, solid manufacturing quality, and proven application experience.

With the tower now securely in place, the primary gas cooler begins its role as the “first gatekeeper” of the gas cooling system, delivering stable and efficient performance to support the long-term, safe operation of the coking plant.
