Analysis of Energy Saving Ways for Large Pumping Station System

An Energy Saving System for a Beam Pumping Unit

Beam pumping units are widely used in the oil production industry, but the energy efficiency of this artificial lift machinery is generally low, especially for the low-production well and high-production well in the later stage. There are a number of ways for energy savings in pumping units, with the periodic adjustment of stroke speed and rectification of balance deviation being two important ...

Saving Energy by Exergetic Analysis of MTP Process Refrigeration System

The exergetic analysis is a tool that has been used successfully in many studies aiming a more rational energy consumption to reduce the cost of processes. With this analysis, it is possible to perform an evaluation of the overall process, locating and quantifying the degradation of exergy. This paper applies exergy approach for analyzing the heat exchanger network design and refrigeration of M...

Dynamic Base Station Energy Saving with Relays

Different Possible Ways for Saving Energy in the Cement Production

In terms of absolute consumption, the cement industry occupies a front position in the ranks of energy consumed industries. The total energy costs (thermal and electrical) make up about 30 to 40 percent of the total production costs of cement. This is why efficient energy utilization has always been a matter of priority in the cement industry. Cement manufactures requires very high temperatures...

Green Mobile Access Network with Dynamic Base Station Energy Saving

The explosive development of ICT (information and communication technology) industry has emerged as one of the major sources of world energy consumption. Therefore, this paper concerns about the BS (base station) energy saving issue, for most energy consumption of the communication network comes from the BSs and the core network. Particularly, we consider dynamically turning off certain BSs whe...
