Energy Renewable

Energy audit is a systematic study or survey to identify how energy is being used in a plant, and identifies energy savings opportunities. Using proper audit methods and equipment, an energy auditory provides the energy management with essential information on how much, where and how energy is used within a factory. This will indicate the performance at the overall plant or process level. The energy manager can compare these performances against past and future levels for a proper energy management. The main part of the energy audit report is energy savings proposals comprising of technical and economical analysis of projects. Looking at the final output, an energy audit can also be defined as a systematic search for energy conservation opportunities.

This information can be transformed into energy savings projects. It will facilitate the energy manager to draw up an action plan listing the projects in order of priority. He will then present it to the organization's management for approval. Providing tangible data enables the management to be at a better position to appreciate and decide on energy efficiency projects. Adopting this activity as a routine or part of the organization's culture gives life to energy management, and controlling the energy use by energy audit is what we refer to as Energy Management by Facts.

Energy audit, unlike financial audit which finds faults, is a fact finding exercise with feasible solutions, and is of particular relevance in energy intensive industries like cement.

The cost of energy as part of the total production costs in the cement industry is significant, warranting attention for energy efficiency to improve the bottom line. Historically, energy intensity has declined, although more recently energy intensity seems to have stabilized with the gains.

Substantial potential for energy efficiency improvement exists in the cement industry and in individual plants. A portion of this potential will be achieved as part of (natural) modernization and expansion of existing facilities, as well as construction of new plants in particular regions. Still, a relatively large potential for improved energy management practices exists. Thermal and electric energy optimization strategies can perform separately or simultaneously. These strategies are divided in to short-term and long-term (with the term of return more than 5 years).

FARAN with a team of four professionals undertook a field-survey for 4 weeks using state-of-the-art instruments, with the cooperation of process and utility engineers specifically drawn from different sections of the plant to discuss and attain the proposed goals.

The following areas/equipment were studied

Many countries rely heavily on coal, oil, and natural gas for its energy. Fossil fuels will eventually dwindle, becoming too expensive to be used for electrical power generation.

How ever, an alternative fuel source can be found in Refuse Derived Fuel , RDF or SRF ( Solid Recovered Fuel ) is a fuel produced by shredding municipal solid waste (MSW) or steam treating in an autoclave. RDF consists largely of organic components of municipal waste such as plastics or waste tire (TDF) and biodegradable waste. RDF processing facilities are normally located near a source of MSW, while an optional combustion facility is normally close to the processing facility; it may also be located at a remote location.

Advanced processing RDF methods (pressurized steam treatment in an autoclave) can remove or significantly reduce harmful pollutants and heavy metals for use as a material for a variety of manufacturing and related uses RDF is extracted from MSW using mechanical heat treatment, mechanical biological treatment or waste autoclave.

The production of RDF may involve some but not all of the following steps:

FARAN Process and Energy Engineering Company, cooperating with its Iranian and European joint ventures is able to provide design, manufacturing and commissioning of a full range of waste to energy facilities in the power & thermal Energy generation plants.
