Application Of Titanium in Oil Refining Industry
Petroleum, the "blood" of modern industry, while promoting social development, also brings high requirements for oil refining equipment. In the oil refining process, due to the diversity and corrosiveness of raw materials, the selection of equipment becomes particularly critical. Strongly corrosive substances such as sulfides and chlorides in petroleum products often deter traditional materials such as stainless steel and aluminum alloys. Titanium and titanium alloys have gradually occupied an important position in the oil refining industry due to their excellent corrosion resistance.
In the petroleum refining process, key parts such as the primary distillation tower, the top of the atmospheric tower and the tower top condenser have been invaded by corrosive media for a long time. Using titanium as the material for these parts not only effectively solves the corrosion problem, but also significantly extends the service life of the equipment. For example, titanium tubes are used in crude oil distillation tower top condensation cooling systems to prevent chloride and sulfide corrosion and ensure the continuity and stability of the production process.
The application history of titanium metal in the refining and chemical industry can be traced back to early coolers. With the advancement of science and technology, the application scope of titanium and its alloys continues to expand, and it is now widely used in key equipment such as heat exchange, condensation and cooling. These equipments are subjected to high temperatures, high pressures and corrosive media during the oil refining process, and the excellent properties of titanium and titanium alloys are the best choice to meet these challenges.
Titanium equipment has been used abroad in the refining and chemical industry for nearly 40 years. Due to lack of oil resources, Japan mainly relies on imported high-sulfur crude oil, so it has accumulated rich experience in anti-corrosion. They used titanium alloy materials to solve the corrosion problem of H2S-HCL-H2O environment and achieved remarkable results. European and American countries also began to use titanium heat exchangers in refineries as early as the 1960s to cope with the challenges of various corrosive media.
On offshore oil exploration platforms, the application of titanium is even more indispensable. In the face of strong corrosion and biological pollution from seawater, the dense oxide film naturally formed on the surface of titanium provides a natural protective barrier for the equipment. Without additional anti-corrosion treatment, titanium equipment can easily cope with the harsh marine environment and ensure the smooth progress of oil extraction.
In our country, although petrochemical industry has always been a pillar industry, relatively few titanium equipment are used in the refining and chemical industry. However, with the rapid development of the economy and the rapid growth of oil demand, especially the increase in the import of high-sulfur crude oil in the Middle East, my country has put forward higher requirements for the technical transformation and upgrading of oil refining equipment. Titanium and titanium alloys will become indispensable materials in the future oil refining industry due to their excellent corrosion resistance.
