Abstract Aerobic sludge from a municipal activated sludge treatment plant, sludge from a conventional municipal anaerobic digester, aerobic sludge from an activated sludge process of a petroleum refinery, and granular sludge from an upflow sludge blanket reactor (USBR) were tested in the deemulsification of a water-in-oil emulsion. All sludges except the last one, showed a good deemulsification capability and could he used for a partial deemulsification of such emulsions.

Summary There are a lot of sludges produced in oil production and storage processes in Liaohe Oil Field. Usually complicated chemical processes are involved in treating the sludge effectively and such surface-treatment processes are subject to high cost and environmental challenges. Therefore, the feasibility and performance of sludge injection into steam-stimulated wells, and sludge sequestration and associated heavy-oil-recovery improvement are investigated on the basis of results of laboratory research and field operation.

Abstract:
The clarification process is the separation of oil from the sludge using a sludge centrifuge. The process in this sludge centrifuge treats sludge/sludge output from CST in the form of sludge underflow. The problem that occurs in the oil separation process in the centrifuge is the high amount of oil that is still included in the final effluent as oil losses. High oil loss is caused by a blockage in the nozzle due to the operational process of the tool that does not pay attention to procedures (SOP) and the lack of operators in the sludge centrifuge related to the maintenance process (washing).

Abstract:
Abstract Oil & gas industries utilize fresh cooling water as a cooling medium for many of their process equipment. Quality of the water is very important in order to ensure the continued integrity and reliability of these systems. This paper discusses various corrosion issues in heat exchangers within the closed loop cooling water system due to water quality. A detailed study was performed to determine the root cause of the corrosion failures which was validated by metallurgical analysis, water chemistry analysis, microbiological study, sludge analysis and inspection of the exchangers.

Abstract:
Knowledge of flow regime, holdup and pressure drop is needed in order to design gas and oil pipelines confidently and to minimize construction and operating costs. Previous public studies of two-phase flow in inclined pipes have used small diameter pipes two inches in diameter or less, and have primarily used air and water as the working fluids at low pressure (near one atmosphere). Present design methods are based upon the results of these experiments. In most advanced analyses available today, the flow regime transition is governed by a Froude number, the balance between inertial and buoyanc
