On September 22, 2020, Chinese President Xi Jinping proposed during the 75th United Nations General Assembly that China's carbon dioxide emissions should peak by 2030 and strive to achieve carbon neutrality by 2060. At the climate summit on December 12, President Xi further emphasized that by 2030, China's carbon dioxide emissions per unit of GDP will drop by more than 65% compared with 2005. As the fourth largest source of CO2 emissions after thermal power generation, steel and cement, in the future, the petrochemical industry will become the top priority in improving energy and resource utilization and reducing comprehensive energy consumption. In order to better achieve energy saving and emission reduction, the selection of thermal pipelines and equipment insulation materials has higher requirements.

In the field of petrochemical industry, aerogel has become a new direction for the application of thermal insulation materials due to its thermal insulation properties. According to the research of China Petroleum Pipeline Science and Technology Research Center, the use of aerogel materials on pipelines has greater comprehensive advantages than traditional thermal insulation materials. First of all, in the heat preservation of heavy oil high-temperature steam injection production pipelines and the heat preservation of medium pipelines in refining and chemical plants, the medium temperature is between 200 °C and 600 °C, and the aerogel thermal insulation material can effectively reduce the amount of external thermal insulation layer. The PH value is neutral and will not cause corrosion, thereby prolonging the service life and reducing later maintenance costs.

Second, the hydrophobicity of the aerogel can make the pipe's insulation waterproof and prevent temperature differences from causing condensation reactions. To achieve the same thermal insulation effect, the required thickness of the aerogel material is smaller (only 1/3 of the rock wool, 1/5 of the expanded perlite), which significantly improves the arrangement rate of the pipeline, reduces the amount of earthwork and construction period, and further Reduce overall costs.

In addition, the aerogel material is lightweight, has a certain hardness, strong flexibility, and is not easy to break. After being cut into a certain size, it can be directly placed on the pipeline for installation and fixation. Compared with traditional thermal insulation materials, the construction efficiency is increased by more than 30%.

With its excellent performance in many aspects, aerogel materials are used in heavy oil extraction steam pipelines, petroleum refining pipelines, oilfield steam injection boilers, distillation towers, reaction pipelines, storage tanks, pumps, valves, natural gas and LNG liquefied gas pipelines, and deep-sea pipelines. It has a good effect on thermal insulation applications such as equipment. At present, large-scale petrochemical companies in the world such as Exxon Mobil, Shell, Chevron, PetroChina, Huachang Chemical and other refineries all use aerogel materials as thermal insulation materials.
