S.N 7 - Qian'an Jiujiang Coking Project

Qian’an Jiujiang Corporation, a major private enterprise established in 1996, relies on a high-performance cooling process for high-temperature coke oven gas. This process is essential to separate valuable by-products like coal tar and naphthalene. As a result, the absorption chiller used must deliver exceptional functionality, operational reliability, and stability. If cooling temperatures fall short, it reduces the output and quality of by-products and degrades the coke oven gas. Unseparated coal tar can accumulate on the inner walls of transmission pipelines and combustion equipment, leading to blockages and damage. Only specialized absorption chillers designed for the coke industry, with stable, reliable, and high-capacity cooling performance—such as units rated at 830,000 kcal/h—are suitable for this demanding application. Any quality issues in the chiller could result in substantial economic losses for the user.
