Biphasic agglomerate clay-iron oxide to the gas sweetening of natural gas.

Natural gas is a mixture of light hydrocarbons such as methane, ethane, propane, butane and other substances; despite, its composition is mainly made of methane, the presence of impurities such as carbon dioxide, steam, hydrogen sulfide and others are the principal cause of operational problems in refineries relates with corrosion, poisoning of catalyzers, mechanical failures, etc. More over, the environmental impact is a bigger problem because all of these substances promotes acid rains and the greenhouse effect increase causing several problems in many places around the world. There are several process to remove the impurities in the pre-treatment step, but one of the most important is the sweetening of natural gas. The Sulfur, in form of an acid gas known as hydrogen sulfide is removed by the use of technologies such as adsorption using solid beds, filtration with porous materials and chemical substance as amines in a procedure known as sweetening of gas. The present research analyze the behaviour of a pellet composed of a mixture of clay and iron oxides obtained from different places of the Ecuadorian regions. The valorization of these raw materials in the formation of pellets in order to use it in the adsorption of hydrogen sulfide is the main objective of the research. The formation of pellets is carried out by mechanic chemical techniques; the characterization of the pellet is done by powder X-ray Diffraction, Scanning Electron Microscopy and Energy Dispersive X-Rays Spectroscopy.
