摘要： PURPOSE:To pick as much fuel as possible that is suitable for a gas turbine from low-sulfur crude oil at low cost and to generate with good heat efficiency by a method wherein gas, whose main ingredient is methane, is simply topped and the obtained low-boiling point fraction is supplied at high temperature to the gas turbine as fuel. CONSTITUTION:Prior to sending low-sulfur crude oil from a crude oil tank 4 to a demineralization process 5, the crude oil is heated in an exhaust heat recovery boiler 2. The demineralized low-sulfur crude oil is supplied to a first simplified topper 6 and the column top gas, together with column top gas of a second simplified topper 8, is gas-liquid separated in a condensation drum 11. Part of it is supplied by a circulating blower 12 to a column bottom of the simplified topper 8 as gas for stripping and the rest is compressed by a gas compresser 13 and is supplied to a gas turbine 1. A condensed fraction in the condensation drum 11 becomes part of fuel for a gas turbine. Out of an intermediate fraction obtained from the column side of the first simplified topper 6, a low boiling point fraction is flown back to the first simplified topper 6 by a first stripper 7 and the rest is used as fuel for a gas turbine.

摘要： PURPOSE:To obtain a gas turbine fuel by mixing a desalted crude oil or low- sulfur crude oil with a liq. petroleum fuel having V and S contents lower than those of the crude oil to thereby adjust those contents of the crude oil to specified values. CONSTITUTION:A crude oil from a crude oil tank 4 is fed to a waste heat boiler 2, where it is heated to 80-150 deg.C. The oil is then mixed with a preheated plain water at desalters 6 and desalted electrostatically. The desalted oil still at a high temp. is sent to a mixer 7 and mixed with a liq. petroleum fuel, e.g. naphtha, from a liq. petroleum fuel tank 8 in a specified ratio to give a liq. fuel having a V content of 0.5ppm or lower and an S content of 1.3wt.% or lower, which is fed to a gas turbine 1. Power is generated with a generator and a high-temp. exhaust combustion gas is supplied to a waste heat boiler 2. Waste heat is used for generating power with a steam turbine 9, and steam is condensed at a condenser 10 and recirculated to the waste heat boiler 2. The combination of desalting with power generation with the gas turbine 1 enables the effective utilization of a low-grade heat energy and the improvement in power generation efficiency.

摘要： PROBLEM TO BE SOLVED: To enable use of the heavy oil for efficient power generating device by mixing a heavy oil component and a light oil component at a specified valve or less of dynamic viscosity, transferring the mixture oil component to a power generating device, and separating the mixture oil component to the light oil component and the heavy oil component, and burning the light oil component in a gas turbine of the power generating device, and burning the heavy oil component in a boiler of the power generating device. SOLUTION: A mixing device 1 mixes a light oil component and a heavy oil component at 800 centistokes or less of dynamic viscosity, and dynamic viscosity of the heavy oil component is lowered so as to facilitate the transference by mixing the light oil component and the heavy oil component. A transfer system 2 transfers the mixture oil to a power generating device, and a separation means 3 separates the mixture to the light oil component and the heavy oil component with the separating operation. The light oil components separated by the separating device 3 are fed to a gas turbine 5, and the heavy oil components are fed to an exhaust gas boiler 6. Power is generated by burning these oil components. Since the harmful material is transferred to the heavy oil component, damage to the gas turbines can be prevented.

摘要： PROBLEM TO BE SOLVED: To improve the power generating efficiency while effectively utilizing the high-temperature exhaust gas to be generated in a heavy fuel oil heating and decomposing device or a raw oil heating and fractional distillation device by providing a route for feeding the exhaust gas generated by the combustion of the light gas from a heavy fuel oil decomposing unit in a heavy fuel oil heating and decomposing device to a boiler. SOLUTION: A heavy fuel oil decomposing unit (raw oil fractional distillation unit) including a heavy fuel oil heating and decomposing device (raw oil heating and fractional distillation device) 1, a gas turbine 2 and a boiler 3 are included as main equipment. Especially, a line 20 for feeding the exhaust gas to be generated by combustion of the light gas from the raw oil fractional distillation unit in the raw oil heating and fractional distillation device 1 to a boiler 3 is provided. Heat recovery in the boiler 3 is aimed at by this line 20. The exhaust gas from the raw oil heating and fractional distillation device 1 maintains the predetermined temperature, and efficiency can be remarkably raised by recovering the heat. Furthermore, since a desulfurizer and an NOx removal system in the downstream of the boiler 3 can be utilized, necessity of providing other desulfurizer and NOx removal system dedicated to the raw oil heating and fractional distillation device 1 is eliminated.

摘要： PURPOSE:To extract a lot of fuel, which is suitable for a gas turbine, from a crude oil or a heavy oil at a low cost by heating the crude oil or the heavy oil after adding fine grain coal to it, cracking this under pressured and heated condition by a cracking reactor to obtain a low boiling point cracked fraction, and using it as a fuel for a combined cycle power generating gas turbine. CONSTITUTION:A crude oil is fed from a tank 4 to a fine grain coal mixing device 5 so as to be added and mixed with fine grain coal. This mixed oil is heated by an exhaust heat recovery boiler 2. Then, the mixed oil is pressured and heated by a cracking reactor 6 so that a crack reaction is caused to provide an off-gas, whose main constituent is non-condensable methane, and a low boiling point cracked fraction, whose boiling point is less than 350 deg.C. A part of the low boiling point cracked fractions is taken out to be cooled down by a heat exchanger 8, and is separated from a gas fraction by a condensing drum 9. Most of the low boiling point cracked fractions are led to the heat exchanger 8 from a flash drum 7. Then, the low boiling point cracked fraction is pressured by a compressor 10 and is fed to a gas turbine 1. In this way, a lot of fuel, which is suitable for a gas turbine, can be extracted at a low cost from a crude oil or a heavy oil.
