project life cycle of distributed energy systems "Energy consumption and GHG emission - A case of beer Auxiliary power supply of brewery in China

in the document we find that we use the life cycle analysis method, where the energy consumption and the GHG emissions of the distributed energy system projects are evaluated, the natural gas of China is studied, the energy system where We design cases with different energy pathways to compare their energy consumption and emissions performance.

The study threw us the project AII natural gas saves 8% of energy and reduces by 38% the GHG emissions a difference of the project that uses the coal and the electricity of the network, the passage of the steps of the energy consumption Life cycle and GHG emission.

Step 1:

Turn the output into an energy input, like the equation. (1) sample. Ejk denotes the energy input jth (when converted to electricity or heat) of the system into technology k (case k). Yijk is the type I output while Cijk is its conversion rate that is based on factors such as the energy efficiency of the machine. Ejk = ΣiYijk / Cijk.

Step 2:

Use the energy input to calculate energy consumption in the life cycle and GHG emissions based on ancient literature, such as Eq. (2) sample. LCk denotes the energy consumption of the life cycle of the technology and the relationship between the energy consumption, the life cycle and the energy input j. As ec. (3) sample, GHGk denotes life cycle GHG emission from technology k, and bj is the relationship between the GHG emission life cycle and the energy input j. GHG emission is measured as CO2 equivalent, as described in the equation. (3). LCk = Σj Ejk * aj (2) GHGk = EMCO2 + 23EMCH4 + 296EMN2O = Ejk * bj.

Step 3:

Calculate the energy savings and the emission reduction rate by comparing the case k with the case k in the previous results, as described in Eq. (4-6). Rekk ', RLCkk', RGHGkk 'are the rate of energy saving, cycle energy saving and reduction of GHG emissions from the life cycle of the case compared to the case k'.

However, the effect of reducing the emission of renewable energy projects is not as essential as the AII natural gas project, and that renewable energy projects have the capacity to develop in the future.

The analysis of the life cycle includes all the stages of its existence, from the extraction and the processes of the raw material, its manufacture, transport, distribution, use, reuse and final disposal of the waste; however, its main function is to provide you with information that will help you better identify the possibilities of dealing with the associated risks and finally make the necessary decisions to improve environmental performance. You can also compare the process of the same product, or products of different materials, so that this information has a direct application in the design and development of the products.

Definition of objectives and scope:
The reasons why the study is studied and the scope where the amplitude, detail and depth of the study are defined are explained.

Inventory of the life cycle:
All inputs and outputs that can cause an impact on the life cycle of a product are identified and quantified.

Evaluation of life cycle impacts:
The inputs and outputs in the inventory are related to the results in the environment, human health and resources.

Interpretation of results:
It is the combination of the results of (ICV) and (EICV), in order to obtain conclusions and recommendations that will take into account the decision making

We (ACV) can apply it in everyday life because helping to recognize the way our acts are part of a system of actions, generating an environmentally responsible lifestyle.
