What are the specified limits for H2S concentration in the lean solution at various plants? This post was last edited by Ma Hai on 2009-3-16 23:27.]
H2S+CO2≤1g/L
The lean liquid supplied to our sulfur recovery flue gas treatment units has a concentration of <1 g/l, whereas the lean liquid supplied to various hydrogenation units has a concentration of <2 g/l.
What poor night? Is it an absorption solution? For example, MDEA
We require that the concentration of hydrogen sulfide plus carbon dioxide be no more than 1 g/l.
Less than 0.1g/L? Under normal operating conditions, it is very difficult to achieve this indicator.
It seems that the accuracy of tests for this parameter isn’t very high; higher requirements are imposed on sulfur recovery, while the requirements for liquid hydrocarbons in other dry gases aren’t that strict
1.5 G/L for dry gas, liquefied gas
The target concentration of H2S in the lean liquid in our facility is 1.0 G/L, for use in the dry gas, liquefied gas, and exhaust gas systems
Parameters of the amine-rich liquid used to absorb hydrogen sulfide: hydrogen sulfide < 0.1 mg/l; carbon dioxide < 1 mg/l
The requirements for the lean liquid are as follows: for low-pressure absorption, the concentration of the lean liquid should be below 1 g/l (hydrogen sulfide + carbon dioxide)； High-pressure absorption; the lean liquid should be at
The indicator for the H2S concentration in our plant’s lean liquid is
