Many dangerous problems can be taken place due to hydrates formation in natural gas
mixtures such as; partial or complete plugging of the system. To avoid this problem, the natural
gas mixtures should be far from the hydrate formation conditions in all steps of processing and
transportation. So, the objective of this work was to select the best calculation technique among
the different techniques available in the literature(Hammerschmidt , Katz (Sp. Gr.) Chart, Katz
Technique, Vander Walls and Platteeuw, Trekell-Campbell Charts, McLeod-Campbell, McLeod-
Campbell and Berge) used for natural gas mixtures to view and control the conditions of the
hydrates formation. So; the comparison should be achieved to select the best technique used to
estimate the hydrates formation temperature to keep the natural gas far from this temperature or
to control and inhibit the hydrates formation, and the
Katz, The Trekell-Campbell and The McLeod-Campbell techniques recorded high accuracy.
Each technique gave highest accuracy at specified conditions.
