The installation of insulating products in industrial facilities is of great importance, due to the reduction in energy consumption that it provides. Industrial processes worldwide account for more than 30% of total energy consumption, so chemical processes must be as efficient as possible, seeking energy savings with the same level of production. The development of this work consists of several chapters; In chapter I, we refer to the theoretical framework related to heat transfer, thermal conductivity of different materials, we explain the law that governs this transfer, such as Fourier's law, the different heat transfer mechanisms such as conduction, convection and radiation, average temperature difference in composite walls, as well as heat transfer through various insulators. In chapter II, we explain the optimization of heat consumption using thermal insulation in steam pipes, takin...
