Cyclic hydrogen purity
Thread Content
Catalyst manufacturers require a purity of 97% for the recycle hydrogen in wax oil hydrocracking units; what is the typical level maintained during production?
It mainly depends on your hydrogen cost; the lowest is 80, while here it’s 90–93
Our figure is over 85%; 97% is a bit high. .
80 or above is fine; too high a value leads to high costs. Around 90 is generally sufficient
