Deionized water and wastewater flux were discussed using module set 1-7 composed of ultrafiltration hollow fiber type modules and reverse osmosis spiral wound type modules. The separation characteristics of ultrafiltration and reverse osmosis membranes were discussed with the variation of applied pressure and temperature. Turbidity and SS were removed effectively from ultrafiltration mem¬brane, and removal efficiency of COD, T-N, and TDS using reverse osmosis membrane was very efficient. Permeate flux increased linearly with the increase of applied pressures and temperature. It was shown that ultrafiltration and reverse osmosis membranes were suitable Lo the advanced treatment and reuse of oil refinery process effluent.

In this paper, the present condition for localization of process pumps and the enhancement method of the localization ratio of process pumps for refinery and chemical plant market were studied. The market of plant industry in the world has grown rapidly since 2000. However, the profit of domestic plant EPC compaies cound not have been increased as much as the market scale because they procured most of equipment from overseas. To make remarkable profit of plant EPC companies in the petrochemical industry, localization of equipments is required. Suitable equipment for localization is process pump applied API 610 standard. An purchased amount of pumps from overseas by domestic plant EPC companies in the last two years were 230 billion won. If process pumps are localized then an profit of plant EPC project will increase.

The installation of light oil facilities or delayed cokers seems to be inevitable in the oil refinery industry due to the heavy crude oil reserves and the increased use of light fuels as petroleum products. Petroleum coke is a byproduct of oil refineries and it has higher fixed carbon content, higher calorific value, and lower ash content than coal. However, its sulfur content and heavy metal content are higher than coal. In spite of disadvantages, petroleum coke might be one of promising resources due to gasification processes. The gasification of petroleum coke can improve economic value of oil refinery industries by handling cheap, toxic wastes in an environment-friendly way. In this study, $CO_2$ gasification reaction kinetics of petroleum coke, various coals and mixing coal with petroleum coke have investigated and been compared by using TGA. The kinetics of $CO_2$ gasification has been performed with petroleum coke, 3 kinds of bituminous coal [BENGALLA, White Haven, TALDINSKY], and 3 kinds of sub-bituminous coal [KPU, LG, MSJ] at various temperature[$1100-1400^{\circ}C$].

As one of staff members participated in the full course of the plant construction project of On-san Refinery to its successful completion. I had my past expierence that the plant construction project was so complicated, and a Long period required, and thus there were so money problems to be solved. Among the problem, I mainly noticed that the following listed points were solved and improved. 1. Each drawing should be in every accuracy possible. 2. Contract should be specified in every detail possible. 3. All invoiced prices of breack down list should be coped with the current market prices. 4. All execution of work should be in the most accuracy. A. Planing execution of work. B. Coordination with supervisor group. C. Economical method for execution of work. D. Safety control. 3, Calculation work field should be established seperately 6. Each staff members should be work at the best of his pride.

The main contribution this research is the development of methodology which is capable of solving problems associated with the capacity expansion and operating schedule of energy industries. The principal concern of such industries is the proper allocation of primary energy which are required for the production of sufficient supply of electricity and petroleum products for the Korea`s energy needs. Nonlinear programming models are developed for power generation expansion planning and for the oil refinery industry. In order to deal with uncertainties about future demands for final energy, chance-constrained programming is used to formulate appropriate constraints. The methodology of the model can be used to evaluate Korean energy and expansion planning in the energy industry, especially the electric power generation industry and the refinery industry.

The main objective of this research is to develop a system which will provide a more efficient fuel saying measure for the current marine products industry situation caused by the increased cost of oil. For that function, the developed system has been verified using the medium of blending oil known as the MF 30 class. As a result, MF 30 was confirmed meeting the International Standard for NOx emissions and content of Sulfur. Oil composition and soot level analysis showed that it is acceptable to use MF 30 class in condition of proper engine running operation and pre-refinery treatment.

In this study, anaerobic digestion, electro-oxidation and electro-fenton oxidation processes were investigated to reduce oily refinery sludge. Anaerobic digestion process was not suitable for oily activated sludge reduction because of characteristics itself and, as experimental results revealed, reduction efficiency was low for electro-oxidation process. However, 40% total suspended solid reduction of oily activated sludge was obtained by electro-fenton oxidation process, operating at pH=1, 0.5 A and $Fe^{2+}$:$H_2O_2$ ratio = 1:30. In addition, higher reduction efficiency was obtained as reaction time was increased (30, 60, 90, 120 min) despite of low $H_2O_2$ concentration. From the results, it has been investigated that electro-fenton oxidation is efficient process for oily activated sludge reduction.

Mixed-matrix membranes (MMMs) containing MIL-100(Fe), a MOF type, were fabricated in this study. MMMs up to 30 wt% MOF loading were prepared, and their gas permeabilities were tested. $H_2$, $CO_2$, $O_2$, $N_2$, and $CH_4$ gas permeabilities increased with the MOF loading, while $SF_6$, the largest kinetic diameter in this study, exhibited reduction of gas permeability with the loading. Ideal gas selectivity of $N_2/SF_6$ improved by 40% as compared with pure polyimide membrane, suggesting the proposed MMMs were suitable for $N_2/SF_6$ separation.
