Using the chemical method to removal the sulfur deposition in the tubes of sour gas production in Jbissah fields


Abstract in English

In this paper, a proposal a chemical solvent to remove sulfur deposits within the tubes production of the wells that most suffer from this problem are done. Where the study was conducted on the referenced study about the characteristics and forms of sulfur in the nature, and explain the Scheme phasic of sulfur and required conditions for the deposition of elemental sulfur within the tubes production. And has been clarified the mechanism of deposition and the outline of a simplified process for the nuclei of molecules from supersaturation sulfur vapor. Has also been depend on the field data of the studied wells /Jbissah-223, Jbissah-220/ (taken from the daily operational reports and Historical Biography of the wells), to conducting laboratory experiments in order to compare the between used solvent at field (NaOH) and proposed solvent (tallow amine activated diethyl disulfides) in this study in terms of the melt the deposited sulfur within the tubes production. and as a result, the curves resulting from the comparison process was drawn and recommending the use of the proposed solvent in treatment the acid gas wells in Jbissah fields that suffer from this problem where this solvent is the most effective and economical.
