"If you control oil, you control all countries." This is what the former Secretary of state of the United States Kissinger once said, so we can see the importance of oil. What makes the petrochemical industry in such an important position? What is the recycling economy of petrochemical industry? Let us uncover the answer from the dimensions of resource exploitation, commodity production, and waste resource recycling.

Oil is known as "black gold".

Oil is a brown, black, combustible and viscous liquid extracted from deep underground. It has the reputation of "black gold". Petroleum is mainly composed of various alkanes, cycloalkanes and aromatic hydrocarbons, the main components of which are alkanes, in addition to sulfur, oxygen, nitrogen and metal vanadium and other elements.

There are several different theories about the formation of oil, and most geologists believe that oil is formed by erosion of organic matter (animal carcasses or plants) after compression and heating under long formations. For example, offshore oilfields are composed of marine animals and algae corpses mixed with silt, buried in thick sedimentary rocks, and transformed gradually after a long period of high temperature and high pressure, and finally degenerated into liquid and gaseous hydrocarbons, which are constantly infiltrated into surrounding rocks with more pores and aggregated together to form. The oil field.

The new technology of microbial oil recovery will not cause environmental pollution.

If you have a chance to navigate the ocean, you may be able to see the offshore oil rigs from afar, which are equipped with hollow drill strings and drilling rigs to exploit the oil layers beneath the ocean; moreover, there is now a new type of offshore oil exploration and development rig that has brought us to explore offshore oil. More convenient.

In order to improve oil production efficiency, oilfield workers usually adopt various measures, such as pressurizing water or natural gas into oil wells, pressing boiling water or high-temperature steam into oil wells, or even burning part of the underground oil, or injecting nitrogen, carbon dioxide, light gasoline to reduce oil viscosity. Nowadays, microbial bacterial liquid or nutrient liquid isolated from the ground can be injected into the reservoir. Compared with other methods, this new microbial oil recovery technology has the advantages of high efficiency, low energy consumption, low cost, and more importantly, it will not cause environmental pollution.

More than 90% of daily necessities are made from petroleum processing products.

The crude oil which has not been processed directly contains many kinds of impurities, such as water, salt and sediment, if not removed, it will directly affect the subsequent processing and increase unnecessary costs; moreover, compounds containing sulfur, oxygen and nitrogen also have a great impact on the performance of petroleum products, so special catalysis must be used in petroleum processing. Agents or microbiological methods to remove them.

In recent years, scientists have discovered a new kind of desulfurization bacteria, desulfurization to the extent of one millionth, amazing. With the rapid development of science and technology, environmental protection has been paid more and more attention. It is gratifying to adopt these green methods in the process of petroleum processing. Crude oil is transported to refineries after dehydration and desulfurization, and different petroleum products are obtained by evaporation or reaction according to different boiling points.

More than 90% of the items needed for daily life are made from petroleum processing products. It's no exaggeration to say that when oil runs out one day, without new alternatives, most of the things around us will not be produced smoothly, without burning energy, no plastic rubber, no shampoo and soap, no car tires... The civilization of human society will change radically, as if to return to primitive society.

The exploitation, processing and utilization of petroleum have accelerated the modernization process, greatly improved people's work efficiency and brought great convenience to people's lives. Gasoline, diesel and other fuels account for about 90% of the total output of petroleum products. Vehicles running on the road, ships sailing at sea, airplanes flying in the sky and so on, if there is no fuel-driven engine provided by oil, only a pile of scrap steel lying on the ground motionless, without these means of transport to play a role, the entire social and economic will be paralysed.

Carbon dioxide emitted from oil combustion can turn waste into treasure.

Petroleum brings us a lot of convenience, but also brings some environmental problems, such as the "greenhouse effect" caused by carbon dioxide emissions into the atmosphere after oil burning. But is the waste gas produced after oil burning useless?

The carbon dioxide emitted by burning oil can also be turned into treasures, recycled, and reused into useful things back into our lives. In 2011, Germany launched the world's first carbon dioxide synthesis polyester material project, using special catalysts to synthesize polyester-polycarbonate from carbon dioxide and polyols. The carbon dioxide needed is supplied through nearby coal-fired power plants.

It's a wonderful cycle. Power plants burn coal to provide us with electricity. Carbon dioxide emissions are recycled to processing plants through special collecting devices and processed into useful products without putting an additional burden on the environment. This is the recycling economy of the green petrochemical industry.
