DEVELOPMENT OF A NEW MATHEMATICAL MODEL FOR DETERMINATION OF WATER CONTENT IN SATURATED NATURAL GAS

Abstract

A new mathematical model for estimating the water content in saturated natural gas has been developed , it is applicable for both sweet and sour gas. lt was tested by applying it for different. mixtures of natural gas containing H2S and C02 and the calculated results were compared by published experimental data, the average absolute error of calculated results is 2.5 %for sweet gas where the average absolute error ranged fror:n 3.1 to 5.5% for natural gas (containing H2S and C02 up to 30 %) .The new model results compared with ten of the current methods and the average absolute error % of the new model is the lowest one for natural gas containing up to 30 sour gas.
