In general, a gas hydrate is a combination of gas and water. For example, a group of mineral compounds are called solid hydrates. These are ionic solids that ions are surrounded by water molecules and make crystalline solids. In any case, in the gas industry, hydrates are a combination of a small molecule of gas and water. During the nineteenth century, hydrates remained an unknown and controversial topic. Early efforts were focused on understanding what compounds make up hydrates and under what conditions they form. During this period, many the constituents of hydrates were discovered. But it was not until the twentieth century that the industrial importance of gaseous hydrates proved. In the oil industry, the term gas hydrate refers to compounds that are usually gaseous at room temperature. These include methane, ethane, carbon dioxide, hydrogen sulfide, etc., and this leads to the term hydrogen and at the same time one of the most common misconceptions about these compounds. Obstruction does not cause much of a problem during normal pipeline operation. However, our unforeseen problems such as pump failure or obstruction problems in the transmission cause hydration and thus blockage of pipelines. It takes several weeks to remove these contractions. The purpose of this work is to investigate the phenomenon of hydrate decomposition in pipelines. A model has been discovered that is similar to the decomposition of hydrates in pipelines. The purpose of this work is to develop an optimal strategy for dehydration in pipelines with bilateral contraction.
