It aimed to dynamic change of oilfield productivity, maked sure that the progressing cavity pump is working in a highly efficient region. It combined variable frequency conversion technology and dynamic liquid level height control technology, the closed-loop control of oil production system with progressing cavity pump is made up of rotation-speed and torsion sensor, stepless motor, frequency converter, PLC and progressing cavity pump. The result show that the system can control the pump submergence depth by adjusting the rotation-speed and torsion of polish rod, and make sure the pump working in a highly efficient region finally. This system also can increase recovery efficiency and pump service life.

Since early 1980, BP has been developing the conceptual design of a Single-Well Oil Production System or SWOPS. This paper outlines the concept and discusses the design and the operational criteria that have been applied in this early work. It further examines some of the innovative areas of technology that have been included in this new approach and outlines the work of the detail design phase, which has just started.

<p class="1"><span lang="EN-GB">Anaerobic digestion represents one form of renewable energy technology but has many wider benefits. This paper reviews the processes involved in anaerobic digestion, the type of systems in place and the use of digestate to improve soil quality. A case is made for the technology in the UK in the context of soil conservation and sustainable agricultural production. Its broader contribution to sustainable development in the United Kingdom is also considered. Low levels of awareness of the benefits of anaerobic digestion, poor access to funds, inadequate incentives, an unfavourable legislative and policy framework for the technology, limited application of digestate for agricultural purposes and the need for further research on digestate use are identified as key factors hindering uptake of the technology. Anaerobic digestion is presented as a technology that can support soil conservation and sustainable agricultural development while also generating both energy and income, enhancing waste and nutrient recycling and promoting environmental protection.</span></p>

The Impact

This study outlines a new forecasting problem of closed-loop production system under environmental aspect by proposing a new solution based on subcontracting. By studying the impact of the carbon tax on decision-making of production optimization, we propose an original economic production and maintenance strategies to minimize the total cost. Additionally, to reduce the total quantity of carbon and its tax, the subcontractor has a role to help either manufacturing or remanufacturing unit during the process of production. Indeed, the principle objectives are to determine the economic production plans for manufacturing, remanufacturing and subcontracting units as well as the optimal maintenance planning characterized by the optimal number of preventive maintenance actions for manufacturing unit, minimizing the total cost of production, inventory, carbon penalty and maintenance.

The Future

This paper reviews key production process for crude palm oil and highlights factors that highly influence the production of crude palm oil. This paper proposes a generic conceptual model for crude palm production process considering these factors. The conceptual model could be modified to consider other factors not included in this paper. The future research would be to construct a simulation model based on the conceptual model proposed in this paper and analyse the effect of these factors on the performance of crude palm oil production system.
