Abstract:

Products from oil and gas exploitation often contains impurities such as H2S, CO2, Hg, etc. The excess of Hg content in exploited product leads to the negative effects on exploitation process, causing damage and corrosion of equipments, and the reduction in the effect of heating systems. In addition, contaminated mercury will disrupt the effectiveness of the adsorbent in the treatment system. In PM3 - CAA block, especially the Northern block, there are many impurities in the oil and gas containing H2S, CO2 and Hg. Some methods have been used to optimize the mercury removal in gas exploited from the Northen of PM3 - CAA such as: change of adsorption type, replacement of new adsorption towers, conversion of old adsorption towers under the exploitation conditions of the platform. The paper, therefore, carries out an in - depth analysis and assessment of the impact of mercury on the products exploited at PM3 - CAA block. From the findings, appropriate solutions are proposed to remove and minimize the disadvantages of mercury existing on production exploition in PM3 - CAA block
