  • high efficient low emission power production from low btu gas extracted from heavy fuel oil Gasification introduction of igcc sofc process
    Journal of Natural Gas Science and Engineering, 2015
    Co-Authors: Mousa Meratizaman, Sina Monadizadeh, Omid Pourali, Majid Amidpour
    Abstract:

    Abstract Today heavy fuel oil is still produced and plays an important role in providing required energy worldwide. However, there could be environmental problems associated with burning these used fuel oils. Because of physical characteristics of heavy fuel oil (high viscosity and density), it is not possible to utilize directly in high efficient power plants same as combined cycle (Gas turbine-steam cycle). Partial Oxidation (Gasification) process is introduced as a solution to reduce the emission production in the power generation cycle from heavy fuel oil. In this process, the heavy fuel oil is converted into syngas (mainly consist of CO and H2). The chemical energy content of syngas can be converted into the electrical energy with high efficiency and low emission production through high efficient cycle like combined cycle or Solid oxide fuel cell-gas turbine. Thermodynamic simulations, environmental and economic assessments of Solid oxide fuel cell-Gas turbine power cycle are performed to investigate the feasibility of introduced system. Results show that the suggested system is not feasible in the current heavy oil price (900 US$ per Ton). The increment in cost of electrical energy in the market (more than 0.2 US$ per kWh) can improve the system feasibility. The change in governmental subsidy trend from raw fuel and electrical energy into emission decrement and high efficient technology can improve such system feasibility.

  • Scenario analysis of Gasification process application in electrical energy-freshwater generation from heavy fuel oil, thermodynamic, economic and environmental assessment

    Today heavy fuel oil is still produced and plays an important role in providing required energy. However, there could be environmental problems as a result of burning these utilized fuel oils.

The chemical energy content of syngas can be converted into the electrical energy with high efficiency and low emission production through high efficient cycle like combined cycle and Solid oxide fuel cell-gas turbine. To improve the efficiency of high temperature power generation system, a thermal desalination unit is coupled with them during the scenario analysis. Thermodynamic simulation, economic and environmental assessment are performed to investigate the feasibility of introduced power generation system. Results show that the suggested scenarios are not economic in the current condition. Applying the emission penalty cost and producing the more valuable product same as freshwater can improve the system feasibility.

  • hydrogen production by Partial Oxidation Gasification of a phenol naphthalene and acetic acid mixture in supercritical water
    International Journal of Hydrogen Energy, 2016
    Co-Authors: Yuzhen Wang, Shuzhong Wang, Gaoyang Zhao, Yanfeng Guo, Yang Guo
    Abstract:

    Abstract A mixture of phenol, acetic acid, and naphthalene was Partially oxidized in supercritical water in order to produce hydrogen. The effects of temperature, Oxidation ratio (OR), reaction time, and reactant concentrations on gaseous distributions, Gasification efficiencies, and reactants removal efficiencies were investigated. Furthermore, the effects of oxygen on the main intermediate products were analyzed, and possible degradation pathways were proposed. Results indicated that higher temperatures significantly promoted the H 2 yield. In addition, small amounts of oxygen (OR 2 and CH 4 . The maximum H 2 Gasification efficiency (240.25%) and H 2 yield (70.16 mmol g −1 ) were obtained at 560 °C, 25 MPa, reaction time of 20 s and OR of 0.2. Longer reaction time enhanced the Gasification efficiencies in 10 s, while the effect was little when reaction times longer than 10 s. The concentrations of the reactants did not significantly influence the Gasification efficiencies.
