る。2. Description of the Related Art At present, in thermal power generation in Japan, a steam turbine is mainly used as a power generation method in which a turbine is rotated by high-temperature and high-pressure steam generated in a boiler. Heavy oil and crude oil are mainly used as the oil fuel for the boiler. Among them, in the case of crude oil burning, low-sulfur crude oil, which has a large amount of wax and a small amount of SO X , such as crude oil from Minas and crude oil from Daqing is preferably used from the viewpoint of pollution prevention. Recently, LNG, which is a good fuel
Combined cycle power generation using is used.

の発電効率（熱効率）も向上させることができる。More recently, in order to improve the power generation amount of an existing boiler by a simple method, a gas turbine is additionally installed beside the boiler to generate electric power with the gas turbine, and the high temperature combustion exhaust gas of the gas turbine is replaced with air. A method known as so-called boiler repowering, in which boiler fuel is burned to burn the boiler fuel, has become known. According to the boiler repowering method similar to this combined cycle power generation, since the boiler fuel is burned by using the combustion exhaust gas of the gas turbine in which about 13 vol% or more of oxygen remains, there is no particular problem in the combustion of the boiler. Since the high temperature thermal energy of about 580 ° C that the combustion exhaust gas of the gas turbine has can be effectively used in the boiler, the fuel of the boiler can be saved, the power generation amount as a whole can be increased, and the power generation efficiency (thermal efficiency) per fuel can be improved.

メリットは多大である。Since crude oil or heavy oil is used as the fuel for the boiler as described above, a storage facility such as a fuel tank is usually provided around the boiler. However, if an attempt is made to newly install the above-mentioned repowering gas turbine, the fuel is usually natural gas, and therefore the storage facility must be newly installed. Cryogenic temperatures are required for the transportation and storage of natural gas, which necessitates a large amount of new equipment costs, and handling natural gas in urban areas has many restrictions from the viewpoint of disaster prevention. Also, LN
Even if the natural gas vaporized from the G storage facility is transported to the oil-fired power plant by a pipeline, enormous cost is required. Therefore, if crude oil or heavy oil can be used instead of natural gas for a gas turbine for repowering, the merit will be great.

ることができないという問題がある。In Europe and the United States, attempts have already been made to use crude oil or residual oil as fuel for gas turbines, but impurities contained in these fuels often cause troubles, such as diesel oil and L oil.
It has been pointed out that the maintenance cost is higher than that when NG is used. And, as the impurity content of the oil fuel used for the gas turbine, the salt content is 0.5 ppm or less,
Sulfur content is 0.05 wt% or less, vanadium is 0.5 pp
It is said that it is desirable to limit it to m or less. In particular,
Salt and vanadium interact with each other to lower the melting point of gas turbine blade metal and cause ash to stick to the blade. Further, the above-mentioned standard of the sulfur content is similarly set from the viewpoint of blade protection. However, even low-sulfur crude oil such as the above-mentioned Minas crude oil or Daqing crude oil used as a boiler-burning fuel does not satisfy these criteria, and there is a problem that it cannot be used as it is as a gas turbine fuel.

Gas turbine fuels that meet all the necessary criteria by simply separating low-sulfur crude oil into low-boiling fractions and high-boiling fractions by simple desalination and simple distillation, and relatively mild restrictions on impurity content The present invention has been completed, paying attention to the fact that various boiler fuels can be obtained at the same time.

In FIG. 1, only main steps are shown, and auxiliary equipment and the like are omitted. The low-sulfur crude oil used in the present invention preferably has a low sulfur content because it can simplify the desulfurization process of combustion exhaust gas. Usually, crude oil having a sulfur content of 1% by weight or less, more preferably 0.9% by weight or less is used. Examples of such crude oil include crude oil produced in Minas and crude oil produced in Daqing mentioned above, which have a large amount of wax. The amount of vanadium contained in these crude oils is usually 0.4-0.
It is 5 ppm. Of these, Minas crude oil has a low sulfur content of about 0.1% by weight or less, and is particularly preferable.

As a desalting method, usually, water is added to the crude oil for washing, and a static voltage of, for example, about 20,000 V is applied to separate the aqueous layer to reduce the salt content. In ordinary petroleum refining, the salt content is set to 3 ppm or less, but the salt content can be easily set to 0.5 ppm or less by repeating the above water washing desalting method.

る。The low-sulfur crude oil whose salt content is adjusted to 0.5 ppm or less is obtained by the atmospheric distillation step 2 or the vacuum distillation step 3.
In the above, it is possible to separate into a low-boiling fraction having a sulfur content of 0.05% by weight or less and a high-boiling fraction having a sulfur content of more than 0.05% by weight. Only one of the above distillations may be performed, or the fraction having a high boiling point separated in the atmospheric distillation step 2 may be further separated in the vacuum distillation step 3. Depending on the crude oil used, the boiling point fraction in which the sulfur content exceeds the boundary value of 0.05% by weight, or the fraction of the fraction differs, but in the case of the above-mentioned Minas crude oil, the gas oil fraction (converted to a normal pressure boiling point of about 340 to 460 OF
Below) to by separating the gas oil fraction (the four hundred sixty to six hundred and fifty O F) below boiling fraction and boiling fraction greater than, about 40% of the low-boiling fraction of the sulfur content of 0.05 wt% And a high boiling fraction having a sulfur content of more than 0.05% by weight can be obtained at a ratio of about 60%. Moreover, heavy metals such as vanadium are hardly detected in the low boiling fraction,

非常に大きい。EFFECTS OF THE INVENTION The present invention employs the above-mentioned constitution to separate the desulfurized low-sulfur crude oil into a low-boiling fraction and a high-boiling fraction by atmospheric distillation or vacuum distillation. Fuels for gas turbines and boilers that meet all the criteria can be obtained. By using these fuels for the boiler repowering gas turbine and its boiler, respectively, the power generation amount is increased while suppressing the maintenance cost of the gas turbine, and moreover, the thermal efficiency is about 40% when the steam turbine is used to generate all the power. Power can be generated with higher thermal efficiency than that, and it is extremely advantageous from the viewpoint of energy saving, prevention of global warming by carbon dioxide, and suppression of generation of harmful substances such as SO X. In addition, there is no need for a storage facility for natural gas that is fired in the gas turbine near the existing boiler, and the economic advantage of simply introducing repowering is very great.
