Product Description

Industrial Primary Coolers for Coke Oven and Coal Chemical Plants

Usage and Application
The primary gas cooler is a mission-critical heat exchanger utilized in coal chemical facilities and coke oven by-product plants. Its central function is to rapidly cool raw, hot coke oven gas (COG) immediately after it exits the gas collecting main. By effectively lowering the gas temperature, the primary cooler forces the condensation and separation of heavy coal tars, naphthalene, and aqueous ammonia from the raw gas stream. This heavy-duty equipment ensures downstream purification processes operate smoothly, protecting sensitive chemical recovery systems while maximizing the yield of valuable coal by-products.
 
Technical Advantages
Our primary coolers are engineered using an advanced horizontal shell-and-tube design to maximize indirect cooling efficiency while minimizing the overall plant footprint. Built to handle highly corrosive and heavy-fouling environments, these coolers feature multi-stage temperature reduction zones—typically utilizing both industrial circulating water and chilled water to drop raw gas temperatures precisely to optimal process requirements.
 
The cooling tubes are manufactured from premium corrosion-resistant materials and are precisely expanded and welded into the tube sheets to guarantee a zero-leakage, gas-tight seal. Furthermore, the strategic tube pitch (spacing) arrangement and integrated flushing nozzles allow for efficient tar removal, preventing naphthalene blockages, minimizing process pressure drops, and significantly extending continuous operational uptime.

Frequently Asked Questions (FAQ)
 
  • What is the advantage of an indirect primary cooler over a direct cooler?
    Indirect shell-and-tube coolers keep the cooling water completely separated from the highly toxic and polluted coke oven gas. This prevents the cooling water from becoming contaminated with tars, phenols, and cyanides, which drastically reduces the burden on your plant's wastewater treatment facilities.
  • How do you prevent the cooler tubes from plugging with heavy coal tar and naphthalene?
    Our coolers are designed with specific internal flow velocities to discourage settling, and they feature integrated flushing systems. Operators can periodically spray the shell side with hot ammonia liquor or hot tar to dissolve naphthalene deposits without needing to take the unit offline.
  • Can the primary cooler be customized for varying gas flow rates?
    Yes. The total heat transfer area, tube length, baffle spacing, and overall shell diameter are fully customizable based on your facility's specific gas throughput and the required temperature differential for your chemical recovery process.
