Based on summarizing some related research results, the prediction of China＇s oil demand and supply in the year 2010 and the year 2020 has been given in the paper. The oil supply and demand situation is discussed on three different levels. Accordingly, suggestions about the oil supply safety and the national economy safety strategies have been given.展开更多

Due to the entry of the Chinese economy into the new normal,the accelerated substitution of old energy by new energy and rigid restrictions composed of low carbon and environmental protection requirements, the oil demand of China will continue to increase overall, but the growth will obviously slow down. At the same time, the newly-increased production capacity in Shandong and coastal region will continuously expand, the supply and demand contradiction will intensify, and the structural excess production capacity of the oil refining industry of China will be prominent. It is suggested that the government should attach great importance to the production capacity of the oil refining industry at the macro level, and deeply carry forward the supply side structural reform, and that enterprises should speed up technical innovation,enhance regional and layout optimization, adapt to market changes and adjust product structure, control oil refining but increase chemical engineering, improve product quality and production efficiency, and constantly promote the international competitiveness of the Chinese petrochemical industry.展开更多

In 2021, oil and gas fields were widely distributed, the number of non-producing oil and gas fields was large;the whole oil and gas remaining recoverable reserves declined slightly, unconventional oil and gas remaining recoverable reserves dropped significantly;the overall oil and gas production continuously increased, the outputs of key resource-host countries kept year-on-year growth;undeveloped oilfields had abundant reserves and great development potential. Combined with global oil and gas geopolitics, oil and gas industry development trends, oil and gas investment intensity, and the tracking and judgment of hotspot fields, the major trends of global oil and gas development in 2021 are summarized. On this basis, the four aspects of enlightenment and suggestions for international oil and gas cooperation and development strategies are put forward: attach great importance to the obligation of marine abandonment to ensure high-quality and long-term benefit development of offshore oil and gas;adhere to the principle of not going to dangerous and chaotic places, strengthen the concentration of oil and gas assets, and establish multi stable supply bases;based on the multi-scenario demand of natural gas, realize the transformation from integrated collaboration to full oil and gas industry chain development;increase the acquisition of high-quality large-scale assets, and pay attention to the continuous optimization of the shareholding ratio of projects at different stages.展开更多

Demand for oil products went on differentiating, and the demand growth of most products sped up. Growth rate of oil production rose again, oil imports increased rapidly, and external dependence of crude oil and oil broke through 60% separately. The State adjusted the prices of gasoline and diesel timely and frequently, based on pricing mechanism. Price hike was higher than reduction. Oil market got weak, yet more stable. China increased the pace of reforms in marketization. In the second half, oil demand will increase continuously but with lower growth rate, oil production will rise more slowly, imports of crude oil and oil will keep on rising rapidly, gasoline and kerosene as well as diesel will witness a net import, and the market of gasoline, kerosene and diesel will be more stable.展开更多

Discharging it to the river without treatment is violation according to Malaysia Environment of Quality Act (EQA) 1974. In Malaysia, ponding system is a conventional treatment method for POME due to its economical and simple process. The treatment process mainly involves two main treatment phases;anaerobic and aerobic degradation. Anaerobic degradation has a proven track record in reducing pollutant properties in POME up to 85%. The real challenge is to increase the efficiency of aerobic process as the biological oxygen demand (BOD) discharge limit has been further reduced from 100 mg·L<sup>-1</sup> to less than 20 mg·L<sup>-1</sup>. One of economical and feasible approach to increase the efficiency of aerobic phase is via bioremediation. This paper describes the limitation of aerobic degradation in ponding system, besides discussed on the important aspects that need to be optimized for a success implementation of bioremediation and its challenges.展开更多
