Patent number: 7658078Abstract: A heavy oil reforming system includes a reforming preheater raising the temperature of a mixed fluid comprising a high pressure heavy oil and high pressure steam up to a temperature for reforming reaction. The mixed fluid having been heated up to the temperature for reforming reaction is introduced into a reformer kept at the temperature for reforming reaction and thereby the heavy oil is reformed. This reforming system allows the attainment of a residence time of 1 to 10 min necessary for reforming in a uniform or nearly uniform temperature field, thereby implementing the manufacturing of reformed fuels from a large volume of heavy oil.Type: GrantFiled: July 29, 2005Date of Patent: February 9, 2010Assignees: Hitachi, Ltd., Petroleum Energy CenterInventors: Koji Nishida, Nobuyuki Hokari, Shin-ichi Inage, Osami Yokota, Hirokazu Takahashi, Masahiko Yamagishi, Akinori Hayashi

Patent number: 7594387Abstract: A gas turbine which can be easily employed in an area where it is hard to obtain a sufficient amount of water, such as an isolated island. Heated and pressurized heavy oil and water in a supercritical state are mixed with each other in a modifying unit to produce fuel-purpose modified oil. The fuel-purpose modified oil is depressurized by a depressurizing valve. Due to a temperature fall caused by adiabatic expansion with the depressurization, the fuel-purpose modified oil is brought into a two-phase state where moisture is in a gas phase (steam) and modified oil is in a liquid phase. The fuel-purpose modified oil is separated into the steam and the modified oil by a gas-liquid separator. The separated steam is condensed to water in a condenser and returned to a water supply line. The modified oil in the liquid phase is supplied to a combustor, thereby driving a gas turbine.Type: GrantFiled: July 12, 2005Date of Patent: September 29, 2009Assignees: Hitachi, Ltd., Petroleum Energy CenterInventors: Shinichi Inage, Nobuyuki Hokari, Osami Yokota, Hirokazu Takahashi, Masahiko Yamagishi

Patent number: 7591983Abstract: The invention is intended to produce high-pressure light fuel gas with good combustibility by contacting and reacting high-temperature, high-pressure water and heavy oil with each other in a contact-reaction unit to extract light oil components from the heavy oil and to remove metals. The high-temperature, high-pressure water and the heavy oil are introduced to the contact-reaction unit for contact and reaction with each other therein. Heavy oil components not dissolved in the high-temperature, high-pressure water are separated by precipitation from hydrocarbon gases and light oil components which are dissolved in the high-temperature, high-pressure water. The separated heavy oil components are burnt or incinerated without any further modification.Type: GrantFiled: August 4, 2004Date of Patent: September 22, 2009Assignees: Hitachi, Ltd., Petroleum Energy CenterInventors: Hirokazu Takahashi, Shinichi Inage, Nobuyuki Hokari, Masahiko Yamagishi, Akinori Hayashi, Osami Yokota, Youji Ishibashi

Publication number: 20080021238Abstract: (Meth)acrylic acid is produced using a reactor (1) through a vapor-phase catalytic oxidation reaction of propane or the like in a raw material gas, and the obtained reaction gas is distributed to a heat exchanger (20) and an absorption tower (30). Heat energy is recovered from the reaction gas supplied to the heat exchanger (20), and the reaction gas cooled in the heat exchanger (20) and the reaction gas distributed to the absorption tower (30) are supplied to the absorption tower (30). (Meth) acrylic acid is recovered from the reaction gas in an absorbing liquid, to thereby produce (meth) acrylic acid. The reaction gas is distributed to the heat exchanger (20) and the absorption tower (30) according to a pressure of the raw material gas at an inlet of the reactor (1). The present invention allows heat recovery from the reaction gas and a stable and continuous operation even when the heat exchanger for heat recovery is clogged.Type: ApplicationFiled: September 7, 2004Publication date: January 24, 2008Inventors: Masahiko Yamagishi, Shuhei Yada, Kimikatsu Jinno

Patent number: 7278255Abstract: Disclosed is a gas turbine power generating system capable of achieving a high output power and a high power generating efficiency under conditions with a small amount of supplied water and less change in design of a gas turbine. A fine water droplet spraying apparatus (11) is disposed in a suction air chamber (22) on the upstream side of an air compressor (2), and a moisture adding apparatus (7) for adding moisture to high pressure air supplied from the compressor (2) is disposed. A regenerator (5) for heating the air to which moisture has been added by using gas turbine exhaust gas as a heat source is also provided. With this configuration, there can be obtain an effect of reducing a power for the compressor (2) and an effect of increasing the output power due to addition of moisture to air (20) for combustion. Further, since the used amount of fuel is reduced by adopting a regenerating cycle, the power generating efficiency is improved.Type: GrantFiled: August 15, 2006Date of Patent: October 9, 2007Assignee: Hitachi, Ltd.Inventors: Shigeo Hatamiya, Masahiko Yamagishi, Osamu Yokomizo, Yoshiki Noguchi, Moriaki Tsukamoto
