With the deterioration of crude oil and the upgrading of refined oil quality, the demand for hydrogen in refineries has increased dramatically. Reducing the cost of hydrogen has become an important development strategy for refineries.
Hydrogen is recognized as an excellent green fuel. Its combustion calorific value is 2.7 times that of gasoline and 3.5 times that of coal. At present, it is mainly used as a secondary / tertiary propulsion fuel for aerospace rockets.
Starting from the source of raw materials involved in the refinery to reduce the cost of hydrogen, according to the full hydrogenation process of the refinery, an independent raw material for hydrogen production unit is built, and the factors affecting the cost of hydrogen production and competitiveness are analyzed.
At present, the application of daily traffic field is being studied at home and abroad, especially in Japan, which takes hydrogen fuel vehicles as the development direction. There are 300 ~ 400 hydrogen fuel powered vehicles output every year. It is planned to build 160 hydrogen fuel filling stations and put into use 40,000 fuel cell vehicles by 2020.
At the same time, hydrogen is also an important industrial raw material and reducing agent. It is widely used in various fields of national economy. It is a synthetic raw material for fine chemicals, pharmaceutical intermediates and other industries, and a protective gas for metallurgy, electronics, glass and machinery manufacturing.
Hydrogen is an indispensable raw material in the process of oil processing.
With the deterioration of crude oil and the increasingly strengthening of environmental protection, the continuous improvement of fuel cleanliness standards, the rapid development of hydrogenation process, the demand for hydrogen in refineries has increased dramatically, and it has become the second largest raw material after crude oil. Seeking cheap hydrogen source is a problem that refineries must consider.
