焦炉煤气氨作碱源氧化法脱硫系统预冷塔的选择分析

摘要

Detailed explanation and comparison were made on the direct and indirect pre-cooling of the gas from the wet desulfurization unit of the coke oven gas in terms of process flow, equipment and operation cost. This can be served as a reference for the design of the wet desulfurization unit of the coking plants.%从生产实践出发,对焦炉煤气氨作碱源氧化法脱硫系统中煤气预冷的直接冷却和间接冷却两种预冷方式进行了工艺流程、设备、运行费用等方面的详细阐述和比较,可为焦化厂同类型脱硫系统的设计提供参考.
