ジャーナル フリーThis report describes the current status of research and development of 200t/d pilot plant.
Integrated Coal Gasification Combined Cycle Power Generation (IGCC), which excels in thermal efficiency, environmental acceptabity and economics, etc.compared with the conventional pulverized coal fired thermal power generation.
The Engineering Research Association for Coal Gasification Combined Cycle Power Systems (IGC Association) has been recieving commission from the New Energy and Industrial Technology Development Organization and has been established. IGC Association is going to promote to design, munufacture and to operate 200t/d pilot plant. IGC Association has started to fundamental and detail design of pilot plant in first two years and has began to construct pilot plant in 1988.
Seven years of research and development period is planned, four years for design and manufacture and three years for operational test and study.
The 200t/d pilot plant consists of air blown two stage pressurized entrained bed gasifier, hot gas clean up having fluidized desulferization unit and granuler bed filter unit and simple cycle gas turbine having the inlet temperature of 1, 300 t class and 13MW.抄録全体を表示PDF形式でダウンロード (1858K) -

ジャーナル フリーThis paper describes the process and its concept, history and present status of development of hot coal gas desulfurization process for Integrated Coal Gasification Combined Cycle Power Generation (IGCC) system. The development is under way sponsored by the ministry of International Trade and Industry (MITI) and the New Energy and Industrial Technology Development Organization (NEDO) formerly as a part of “Sunshine” project.The process consists of a sulfur absorber and a sorbent regenerator both of which are two stage fluidized bed and uses iron oxide as a sorbent. Since the fluidized bed system operates with continuously circurating sorbent, and has uniform temperature through out the each bed, stable continuous operation, good control of temperature of reactor and stable continuous heat recovery can be achieved. The development is at a stage of operation of pilot plant treating coal gas from 40tons (coal) /day fluidized bed coal gasifier. A larger plant as a part of 200tons (coal) /day IGCC pilot plant is under construction.抄録全体を表示PDF形式でダウンロード (1039K) -

ジャーナル フリーWe aim to establish the technlogy of fixed bed type hot gas cleanup system for the coal gasification combined cycle power generation. We conducted test using the 2t/d process development equipment and various basic studies to obtain data for scale up the pilot plant.
Main result in the technology of porous filter dust collection is favorable characteristic of pressure loss increase at the filter during collecting particles in the coal gas. We can estimate long term reliability of the porous filter from the characteristic.
In the technology of fixed bed desulfurization, the bed temperature in the regeneration process has great influence on the reliability of the desulfurization sorbent. We clarified the characteristics of regeneration temperature at various regeneration condition (gas flow rate, temperature and O2 concentration et al.). We also obtained the profile of the decrease of desulfurization sorbent capacity in early desulfurization/regeneration cycles due to the increase of the residual sulfur and the change of sorbent physical properties. We use these results to establish optimum regeneration condition.
We think it is necessary to estimate overall at the large sized unit for the future.抄録全体を表示PDF形式でダウンロード (1331K) -

ジャーナル フリーIn case when the assumptions of ideal gas and ideal solution are reasonably valid.
The poynting equation may be used to estimate the vapor pressure of the liquid under high pressure Pr.
Equilibrium vaporization constant of each component K, under hypressure hydrogen is calculated by the following equation:
Ki=No (Pπi/Pni) (Pni/Po)
The results of calculation were plotted in chart on relationship between temperature and equilibrium vaporization constant with parameter of carbon number.
The figure thus obtained serve well to explain the actual operation of the kerosene hydrocracking plant.抄録全体を表示PDF形式でダウンロード (554K) -

ジャーナル フリーNew dry flue gas desulfurization process have been developed. In this new process, flyash is utilized as a raw material of the SO2 absorbent.
The reactions of this new absorbent with SO2 are very different from those which occur in the typical lime injection or semi-dry absorption processes. 90% SO2 removal efficiency was attained under the condition of 1.05-1.15 Ca/S molar ratio.
The numerical simulations of SO2 removal in a cross current moving bed absorber are presented. The results are compared with those from a demonstration plant having a capacity of 50000 Nm3 of flue gas per hour.
The reaction is supposed to proceed as follows: SO2 in the gaseous phase initially reacts on the surface of absorbent, a layer of product CaSO4 being formed.
The SO2 absorption rate was determined to be
dQ/dt=∅ {K1' (Qs-Q) +K2'Q},
where K1', K2', Qs and 1 are determined absorption curve of absorbent. dQ/dt depends on many factor, such as gas temperature and SO2, NO, O2, CO2 and H2O concentration.
The numerical model is based on two equations of absorption rate and a mass balance for cross current moving bed absorber. Computed results agreed well with test data.抄録全体を表示PDF形式でダウンロード (986K) -

ジャーナル フリーThe gasification studies on the selected cellulosic wastes (Saw dust, Coir dust, Copra meal and Cassava bagasse) by fluidized bed method were investigated to determine the ideal conditions and variables suitable for generating power.
Experimental runs on the steam and air gasification were carried out using bench scale gasification apparatus.
The results on the steam gasification showed that at varying bed temperature ranging from 750 to 900°C, gas product with high H2 and CO content (more than 70%) having high heating value (2, 500-3, 700 kcal) were obtained.
The ranges of heating values of the produced gas obtained from air gasification at appropriate operating condition were 1, 000-1, 350 kcal for saw dust, 1, 170-1, 300Kcal for coir dust, 1, 200-1, 700Kcal for cassava bagasse, and 1, 350-4, 800 kcal for copra meal.
Preliminary test run of the gas engine was done by charging LPG mixed with air to determine the minimum practical heating value for smooth operation. Results of the test run showed that 1, 200 kcal was minimum heating value with gas pressure of about 1, 200 mmH2O to maintain the smooth operation.
Based on the data from the preliminary test, the gas fuel products generated from saw dust were tested on the gas engine.
Results showed that low calorie gas products with heating value as low as 1, 300 kcal can be utilized to run a gas engine for generation of electric power.抄録全体を表示PDF形式でダウンロード (975K) -

ジャーナル フリーCoal liquefaction test of Teiheiyo coal has been carried out in the presence of three natural pyrites in 0.1t/d bench plant. The effect of their amount of addition, particle size and reaction condition on coal liquefaction was examined. These results were compared with those in the presence of synthetic pyrite, iron are and red mud.
As a result, it was found that the concentration of active hydrogen increases with increasing the surface area of natural pyrites as well as the increase of pressure to stabilize fragments produced due to thermal cleavage, to suppress the formation of gaseous products and to increase oil yield.抄録全体を表示PDF形式でダウンロード (407K) -
