THERMAL AND CHEMICAL DEPOLLUTION FOR EMISSIONS
RESULTED FROM INDUSTRIAL THERMAL PROCESSES
Due to the Climates Changes Intergovernmental Comity (IPCC)
investigations, carbon dioxide is the most significant emitted warm effect gaze
from human activity. CO2 emitted quantity must be reduced and even stopped
regarding to the global treaties. Carbon dioxide concentration and recuperation
from thermal installation emitted gazes is the first major step in carbon dioxide
problem resolution. This desiderative cold be resolved thru vacuum absorption
(VSA) using molecules or absorbents for CO2 suppression from eliminated
gazes from thermal aggregates.

RECYCLING INDUSTRIAL WASTEWATER WITH HEAVY
METAL CONTAIN BY ION EXCHANGE
Removing heavy metal ions from industrial wastewater by ion
exchange is based on the properties of the ion – cationic exchanger to change
their own captions with those from the wastewater. The purification technology
by ion exchange consists of replacing the polluting ion from the used water with
another ion, which is much less polluted, or which results in obtaining an
insoluble chemical compound or one that is easier to remove. The ion
exchange between the zeolite and the heavy metal ions is a type of adsorption
-chemical reaction – denuding, and the transfer through the zeolite pores
determines the process. The process is favorite by temperature increase, by pH
increase of the solution from the wastewater, the heavy metal ion concentration
increase of the initial solution, the quantitative increase of the volcanic tuff.

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
makes an analysis of the most used methods; we present a hybrid treatment
installation.

MODELING PLATES WITH SHOT PEENING
This paper presents the new method for modeling the plates, by using
the shot peening. Shot peen modeling is a partially effective forming process
derived from the shot peening surface treatment. During impact of the shot, a
certain amount of its kinetic energy is transformed into plastification of the
component. When shot velocity is fairly low only a thin layer of the component’s
material is elongated resulting in a convex curvature. If shot velocity is
increased, concave curvatures are produced.

CONSIDERATIONS ON THE POSSIBILITY OF MAKING
PARTS HARD CRUST WEAR AND CORROSION RESISTANT
USING INDUSTRIAL WASTE (RECYCLED MATERIALS)
Manufacturing parts to take anti-wear and corrosion crust, using
industrial waste, applicable in the chemical industry and light is a new field of
research and development in Romanian industry. Achieving that hard crust
components used in aggressive environments, represents a new area explored
enough, and is a ,,stone attempt’’ to research engineers.

FUSIBLE ALLOY USED TO MAKE CASTING PATTERNS
The main scope of the project lies in supporting the knowledge
development in the field of small series of unique parts, mainly for the
automotive industry, by producing a technology and a device for patterns
through self formation from an easily fusible alloy with basalt fibers that enable
both a rapid pass from one type of parts to another, so that the fabrication flow
can be easily changed, as well as innovative research for the achievement of a
composite material based on Bi-Sn alloy with basalt fibers with higher technical
characteristics.
