What are the advantages of steam heating compared to on-line furnace reheating? () A. It is less likely to produce excess oxygen and sulfates, and the interval between catalyst regenerations is extended. B. The catalyst’s lifespan is prolonged； C. Helps to improve the conversion rate ； D. It allows for a reduction in pipe diameter and equipment size.
I couldn’t tell whether this is a multiple-choice or single-choice question
A. Excess oxygen is not easily generated, sulfates are not easily formed, and the interval between catalyst regenerations is extended. B. The catalyst’s lifespan is prolonged；
ABCD. . . . . . . . . .
Comparison between steam heating and on-line furnace reheating: What are the advantages (AB)? A. It is less likely to produce excess oxygen or sulfates, and the interval between catalyst regenerations is extended. B. The catalyst’s lifespan is prolonged； C. Helps to improve the conversion rate ； D. It allows for a reduction in pipe diameter and equipment size.
A. Excess oxygen is not easily generated, sulfates are not easily formed, and the interval between catalyst regenerations is extended. B. The catalyst’s lifespan is prolonged；
Follow the trend, AB – does this refer to the heating method in the first-stage converter?
