Capacity single

Steam-Reforming Natural Gas. Natural gas is the single most common raw material for the manufacture of ammonia. A typical flow sheet for a high capacity single-train ammonia plant is iadicated ia Figure 12. The important process steps are feedstock purification, primary and secondary reforming, shift conversion, carbon dioxide removal, synthesis gas purification, ammonia synthesis, and recovery. 

Axial-Plow Propeller-Type. For high capacity, single-stage propeller-type vertical pumps are used. One appHcation of this design is as an intake of cooling water from a river or a hoi ding basin via a pipeline.

Commercial plants The technology has been selected for use in over 40 units having design capacities (single train) ranging from 320 to 850 Mmtpy. The aggregate capacity of these units exceeds 8 MMmtpy. 

With the increase of coal production capacity, single power of large-scale production equipment has been increasing every year, but explosion-proof converters cannot meet the demand of it. The three-level converters upgrade the output voltage level to reduce the current stress, which can improve performance and price ratio.
