Devices of the same type – which one is more energy-efficient?
Thread Content
As the title suggests, for devices of the same type, are large-scale systems more energy-efficient than small-scale ones? For example, among synthetic devices of the same type with two reaction stages, is one with an annual production capacity of 200,000 tons more energy-efficient than one with an annual production capacity of 150,000 tons?
It mainly depends on the process used in the ammonia synthesis plant, as well as its consumption levels – such as the coal, electricity, and water consumed per ton of ammonia produced. Of course, with a larger scale, the one-time investment in utility facilities is relatively reduced; this is what is known as economies of scale, which results in lower costs.
This is what people refer to as economies of scale; generally, producing ammonia at a scale of 30-60 is more energy-efficient
Not necessarily; it depends on what production process is used and how well the management is handled； Economies of scale account for a small proportion.
Hehe, it’s not necessarily the case that a system with more stages is more energy-efficient; there are systems that use only one stage of steam catalytic conversion and yet are still very energy-efficient. It’s not guaranteed that a two-stage system will be more energy-efficient than a single-stage one.
I already said it’s the same process. Are 150,000 tons and 200,000 tons, or 300,000 tons/150,000 tons not as energy-efficient as larger units? ?
