【Q&A Question 018】As of January 18, 2018, what does the \"three highs and one low\" in hydrogen production facilities refer to? “\"Three highs and one low\" refers to: the three highs being high inlet and outlet temperatures, high gas velocity, and high heat flux, while the one low is the low water-to-carbon ratio. (Unless otherwise specified, all questions and answers are based on hydrogenation units.) ) Due to the limitations on the number of posts in the “One Question per Day” section, “One Image per Day” has been moved to the registered devices section; you can access it through the directory I posted.

Answer: The three highs refer to high inlet and outlet temperatures, high gas velocity, and high heat flux, while the one low refers to a low water-to-carbon ratio.
High converter exit temperature, high gas velocity, high heat flux, and low water-to-carbon ratio

High input, high consumption, high pollution, low efficiency
High inlet and outlet temperatures, high air velocity, high heat flux, low water-to-carbon ratio
High conversion inlet temperature, High conversion outlet temperature, High carbon space velocity, Low water-to-carbon ratio
Refers to \"high input, high consumption, high pollution, and low efficiency\"”
Three highs: high conversion inlet temperature, high conversion outlet temperature, and high carbon space velocity. Low: low water-to-carbon ratio
High inlet/outlet temperatures, high space velocity, high heat flux, low water-to-carbon ratio
The three highs refer to high conversion inlet and outlet temperatures, high gas velocity, and high heat flux, while the one low refers to a low water-to-carbon ratio.
