摘要
焦炉荒煤气经初冷后，少部分氨存在于剩余氨水中，大部分的氨仍留在煤气中，这2部分的氨都应加以回收。介绍了初冷煤气中氨以及剩余氨水中氨的各种回收工艺以及其优缺点，并对各种工艺的使用情况作了简单叙述。
After the primary cooling of coke-oven raw gas, a small part of ammonia presents in the residual ammonia water, while the majority remains in the gas. Two parts of ammonia should be recycled. This paper introduces various recycling processes of ammonia in the primarily cooling gas and the residual ammonia water, as well as their advantages and disadvantages. The uses of these processes are also described briefly.
