摘要
由于原料渣油中硫含量对合成氨生产中耐硫变换催化剂活性的影响,须在原料渣油中添加适量硫黄。本文针对熔融硫的添加部位进行了对比,认为添加在低压渣油泵进口的方案为优。
In view of the fact that sulfur confent in feed oil will put influence on sulfur-resistant shift catalyst in ammonia production,a comparison among molten sulfur feed spots was made and the inlet of low pressure oil pump was to be selected.
