Benefit of energy saving

Benefit of energy saving (reduce pressure). According to the balance of mass and energy for ammonia converter ... 

When the load or output y) and inlet gas flow (Yin) of the converter is the same, the outlet concentration (v out) and the net value (A99) of ammonia must be the same if the temperature (tin) and the composition of inlet gas is the same, then the temperature of outlet gas (tout), volume of recycle gas and vent gas is the same, i.e., the heat recovery rate and the gas consumption of the converter is the same too (seen in Table 9.19). Therefore, in such conditions, the benefits of using the new highly-effective catalyst are embodied in the benefits of energy saving and pressure reducing which is shown in Table 9.21 which is an extension of Table 9.19.

Some conseivation measures do not easily fit into the form of an initial investment followed by a stream of energy savings because there will be other costs and benefits occurring during the measure s operating life. Furthermore, it is difficult to incorporate peak power benefits into the CCE approach. In these situations, a more precise analysis will be necessary. However, the CCE and supply cuive approaches provide first-order identifications of cost-effective conseivation, those... 

Reductlons in vehicle traffic in violation areas at a net annual cost savings of about 100,000 per yg/m. Associated benefits include energy savings, fewer road and auto maintenance costs and important carbon monoxide and hydrocarbon emission benefits. 

Academic studies that involve energy efficiency in the textile industry are not at a desired level compared to the volume of the sector in the world. Most of the published studies focus on the energy savings, measurements, comparison of current methods and technologies, potential benefits and energy savings in plant size and national size. 

Process intensification is frequently defined in terms of its benefits to the process industries, in particular the chanicals sector. An appredalion of the benefits that PI can give in terms of energy saving, safety, company profitability and new opportunities will help readers to understand the motivation behind PI use when studying the applications chapters. There are also limitations to PI, and an awareness of these is essential if correct application is to be assured. This chapter has started to raise the awareness of the reader to aU these aspects, as well as directing him/her to other chapters where the teehnologies and uses of PI are elaborated upon in more depth. 

Because zinc-based alloys have low melting points, energy savings in the melting operation are substantial and the foundry operation is essentially free of fume. With the current trend of increasing energy costs and pollution control, cost benefits can be considerable (114). 

In summary, heat-driven cycles for cooling or heat pumping can have energy saving and environmental benefits. There are also niche applications in developing countries or remote areas. Adsorption cycles using active carbons are one of a number of approaches that might be economically viable. 

States, companies and consumers are saving millions of dollars in energy costs since new computers, mostly replacement systems, are being plugged in at a rate of over thirty million a year. Just as importantly, society receives the environmental benefit of reducing the need for additional electric power plants. 

Most induction ac motors are fixed-speed. However, a large number of motor applications would benefit if the motor speed could be adjusted to match process requirements. Motor speed controls are the devices which, when properly applied, can tap most of the potential energy savings in motor systems. Motor speed controls are particularly attractive in applications where there is variable fluid flow. In many centrifugal pump, fan, and compressor applications mechanical power grows roughly with the cube of the fluid flow. To move 80 percent of the nominal flow only half of the power is required. Centrifugal loads are therefore excellent candidates for motor speed control. Other loads that may benefit from the use of motor speed controls include conveyers, traction drives, winders, machine tools and robotics. 

Energy intensity. Energy intensity is an obvious target for green product design. This is the easiest dimension to identify commercial benefits. Lower energy intensity can clearly either save manufacturing costs, or total cost of ownership for the user.
