SMART ELECTRIFICATION. REDESIGN.
THE FUTURE ENERGY CHAIN
Over the next decades, the world will face increasing challenges to
supply energy in sufficient quantities, while reducing carbon emission levels.
As the first IEC (International Electro technical Commission) President, Lord
Kelvin, always said: “If you cannot measure it, you cannot improve it!”. This
statement is especially true here: without measurement you can’t credibly
demonstrate energy efficiency improvements. The IEC provides and will
continue to provide many of the measuring standards that are the basis for
benchmarking, energy audits and compliance assessments. Electricity is the
most easily controllable form of energy. The IEC believes that electricity will
be the most important contributor to climate change mitigation.
The IEC Market Strategy Board, which comprises high-level
executives from industry, has recently prepared a White Paper on Smart
Electrification which maps out global energy needs and potential solutions
over the next 30 years and the IEC’s role in meeting the challenges. Section
6 of this White Paper demonstrates what needs to change in the energy
chain to achieve the CO2 emission levels that can help humanity to mitigate
climate change.

CO2 emission level, redesign, reference architecture, smart grid, energy,

THE ECONOMIC OPTIMIZATION OF A STEAM POWER
PLANT
This paper provides an Optimization System for an industrial site. The
real-time system will determine the appropriate loading for various boilers and
steam turbines to best meet the site’s demand for steam at various pressures
and generate electricity. We have intended to perform the optimization across
the plant as a whole using PredictPro, although this technology usually
operates on a single process unit.
To provide the system’s functionality there are a number of possible
approaches, including: a steady-state optimizer, utilizing a process model of the
plant (in our case gains model) and the use of the optimizer functionality within
the PredictPro model predictive controller.
Any power plant that can be described by a “gain matrix” with less
than 40 Manipulated Variables (MV) and 80 Constraints (CV) can be treated by
the application in such a configuration.

OPTIMIZING THE ADMINISTRATION OF ELECTRICAL
ENERGY BY USING BUILDING MANAGEMENT SYSTEMS
In order to efficiently manage the electrical energy consumption of the
buildings it is needed an intelligent system named Building Management
System (BMS), which can be structured on 4 levels: peripherals, input/output
modules, local stations, central management station. The local stations manage
the peripheral in their area and can communicate with other stations and with
the central one. The main modules of a BMS are: HVAC station, Chiller station,
Lighting (internal and external), Security, Elevators. The central management
station has a mainframe with add-on cards for communication with the local
stations and the peripherals. The software permits monitoring the power
distribution at all levels, and also changing the parameters for various system
components (pumps, ventilators, heating, chillers etc). All events must be
recorded in database and presented to the user when needed. Modern BMS
can also be controlled remotely (via Internet). Using a BMS for electrical energy
management can significantly decrease the energy consumption of a building.

USING WASTE AS AN ALTERNATIVE ENERGY SOURCE
Urban waste in storage can be an inexhaustible source of energy.
Under the action of bacteria, an organic substance from waste undergoes
anaerobic reduction as a result the significant amount of biogas, which contains
an average of over 50 % methane, which has a high calorific value. These
gases can be captured by a network of pipes, filters, dryers can be fuel for an
internal combustion engine driving a generator, or can be liquefied. Thus from
the waste, obtain electricity, clean energy and easy to carry. In this way all
urban landfills in Romania can become energy producers. The benefits are
enormous, in that energy from waste sites and biogas is captured with a more
powerful greenhouse gases than carbon dioxide.

TRENDS IN BIOPLASTICS OBTAINING
MATERIAL PRODUCTION
Bioplastics, industry and agriculture are close connected. On a side
renewable resources from agriculture are basic feedstock for bioplastics
manufacturing. On the other side, products made from bioplastc materials have
a large applicability in agriculture, and as packaging in food industry. After the
bioplastics fulfill their mean and become residues, the cycle is closed by using
them as compost for fertilizer and a soil improvement in agriculture.
This interdependence lied when about 50 million hectares in EU are
not needed for food production for new opportunities in agriculture.

ASPECTS REGARDING WATER QUALITY AS AN
IMPORTANT ISSUE IN IRRIGATION
In spite of progress achieved in this field, the processes taking place in
agriculture are still under the unfavorable effect of some natural factors, their
occurrence, duration and extension in space not being preventable or entirely
removed. Irrigated agriculture has an increasingly important part in
environmental protection in the rural areas, at the global level irrigation being
tributary to supply with water of good quality. Assessment of water quality must
be performed on a regular basis. Equipment developed during the phase of
experimental model has been tested at ANIF- Territorial Branch Olt – Argeş.

The origin of acid mine water with high content of metals is
accelerated oxidation of iron pyrite and other metal sulfides as being due to
exposure of these minerals in contact with oxygen and water, as a
consequence of metal ore processing. There are two general categories of
treatment methods that are well researched: active treatment, which requires
the use of chemical treatment systems for acid buffering and passive treatment,
which allows biological and chemical processes occurring naturally in the

HAZARDOUS WASTE TREATMENT OF MEDICAL ACTIVITIES
According to current legislation, waste treatment from medical
activities aimed to achieving a final product of the environment and health
friendly. The most popular method treatment of these types of waste is
incineration. As an alternative to those, it has been developed installations that
do not use incineration, and today is known different alternative medical waste
treatment, of which the most commonly used are steam sterilization,
microwaves, chemical treatment, thermal treatment (pyrolysis). The paper

MINERALS DISTRIBUTION IN COAL FLY ASH FROM
PAROSENI POWER PLANT
Large ash dumps, formed in time, are a high harmful potential for
environment. Our study points out the mineral contained in fly ash resulted at
Paroşeni power plant. The X-ray diffraction analysis reveals large amounts of
quartz, mullet, potasic feldspar, Seri cite and hydrated hematite. Microscopy
investigation prove that quartz particles keeps their initial equiaxial shape
meanwhile higher amount of mullet and hematite feature spherical shape due
to their melting during coal burning. The quantitative microscopic analysis
reveals three particles domains: the larger one having the average diameter of
100 μm, the intermediary one having the average diameter of 44 μm, and the
finest one having the average diameter of 23 μm. Quartz particles are often
found in the larger particle range, hematite hydrate and mullet are often found
in the intermediary particle range, meanwhile feldspar and Seri cite are situated
mainly in the finest particle range.

NOISE POLLUTION
Noise pollution is a danger that threatens population and environment
along with other factors such as: gas emissions in the atmosphere, the
discharge of waste water with dangerous substances content on soil and water,
storage of waste on the ground.
It is found that both sounds, how much and infra-sounds and ultra –
sounds have adverse effects on humans. The most important source of noise in
the larger cities is road traffic generated by the friction of the wheels on the
asphalt and packaging the engines.
To reduce the noise level of the individual measures are taken which
are the personal discipline, and technical measures covered by the obscuration
of the source of noise, protected housing, which is situated the antiphon rooms
