Process for the production of natural gas condensate having a reduced amount of mercury from a mercury-containing natural gas wellstream

A process for the production of a natural gas condensate having a reduced amount of mercury from a mercury-containing natural gas wellstream comprising the steps of:

• separating said wellstream into a gaseous fraction and a liquid fraction,
• purifying said gaseous fraction with a carbonate solution which has the ability to absorb carbon dioxide and hydrogen sulfide,
• heating the resulting carbonate solution to expel an acid gas comprising carbon dioxide and hydrogen sulfide,
• increasing the pressure of at least a portion of said acid gas,
• mixing said increased pressure portion of said acid gas with said liquid fraction,
• passing said mixture through a filter to remove mercuric sulfide,
• passing said filtered mixture over a substance capable of adsorbing hydrogen sulfide, and
• separating said mixture into a first stream comprising light hydrocarbon components and a second stream comprising a natural gas condensate.

A process for the production of a natural gas condensate having a reduced amount of mercury from a mercury-containing natural gas wellstream comprising the steps of:

• separating said wellstream into a gaseous fraction and a liquid fraction,
• purifying said gaseous fraction with an aqueous potassium carbonate solution which has the ability to absorb carbon dioxide and hydrogen sulfide,
• heating the resulting carbonate solution to expel an acid gas comprising carbon dioxide and hydrogen sulfide,
• increasing the pressure of at least a portion of said acid gas,
• preheating said liquid fraction,
• mixing said increased pressure portion of said acid gas with said preheated liquid fraction,
• passing said mixture through a filter to remove mercuric sulfide,
• passing said filtered mixture over a substance capable of adsorbing hydrogen sulfide, and
• separating said mixture in a stabilizer column into a first stream comprising light hydrocarbon components and a second stream comprising a natural gas condensate.
