To me both reason can incresed acid gas loading in lean amine. 1.When lean amine temperature is low then then amine absorb more quantity of H2S,CO2 which result high acid gas loading in lean amine. 2.When amine solution concentration is hiegher than 50/50 then slow absorption of CO2 but H2S absorption incresed which result high acis gas loading in lean amine. Note: Lean amne temperature is the main thing to increase acid gas loading. Jan Muhammad My take is that if your amine titration is higher than 50%, and are having trouble with loadings, then you are probably running out of regeneration (still/reboiler). It is critical to maintain a good overhead temperature and reboiler temperature so that the amine can be regenerated. Proper titration and lean amine temps tie back into this...
The reaction represented by HgCl2 + H2S → HgS + 2HCl is a double displacement reaction, specifically a precipitation reaction. In this process, the mercury(II) chloride (HgCl2) reacts with hydrogen sulfide (H2S) to form mercury sulfide (HgS), which is a solid precipitate, and hydrochloric acid (HCl). This type of reaction typically involves the exchange of ions between the reactants.
Secondary amines can be an alternative to primary amines in H2S scavengers. These compounds have similar reactivity towards H2S but can offer different selectivity or performance in scavenging applications. Each amine type has its own advantages and limitations depending on the specific requirements of the process.
This is a double displacement reaction. Iron(II) sulfide (FeS) and hydrochloric acid (HCl) react to form iron(II) chloride (FeCl2) and hydrogen sulfide gas (H2S).
Yes, natural gas needs special equipment to get like Amine Plants, Oxygen removal, H2S removal equipment.BlueSky Midstream

The decomposition reaction of hydrogen sulfide (H2S) is: 2 H2S -> 2 H2 + S2. This reaction occurs when hydrogen sulfide is heated to a high temperature, breaking down into hydrogen gas and sulfur.

The balanced chemical equation for the reaction between H2S (hydrogen sulfide) and CuSO4 (copper(II) sulfate) is: H2S + CuSO4 → CuS + H2SO4 This equation is balanced as it shows the conservation of atoms of each element on both sides of the reaction.
H2(g) + S(s) H2S + 20.6 kJ
There are 2 sulfur atoms in the chemical reaction H2S plus SO2 plus H2.
The chemical equation for the reaction between sulfur and hydrogen is: S + H2 → H2S. This reaction forms hydrogen sulfide gas.
The balanced equation for the reaction between iron(II) sulfide (FeS), hydrochloric acid (HCl), and hydrogen sulfide (H2S) is: FeS + 2HCl + H2S --> FeCl2 + H2S

Silver reacts with hydrogen sulfide (H2S) to form silver sulfide (Ag2S), but does not react with hydrochloric acid (HCl) because silver is more reactive with sulfur than with chlorine. The reaction of silver with H2S is a precipitation reaction that forms a solid silver sulfide, while HCl does not produce a reaction with silver as it is a weaker oxidizing agent compared to sulfur.
The balanced chemical equation for the reaction is: ZnS + 2HCl → ZnCl2 + H2S
The reaction between hydrogen sulfide (H2S) and sulfur dioxide (SO2) is a redox reaction that forms sulfur (S) and water (H2O) as products. This reaction can be represented as: 2H2S + 3SO2 → 2S + 3H2O
