Gas condensate consists essentionaly of two kinds of compounds:
hydrocarbon compounds and nonhydrocarbon compounds such as
(CO2, H2S, N2, H2O……..). Nonhydrocarbon compounds form a
very small rate in gas condensate ,but it effect on many properties
of
gas condensate. This research studies the effect of these componentson the pseudocritical pressure and pseudocritical temperature of gas condensate which are very important to study the phase behavioure of gas condensate and to determine the region of retrograde phenomenas which happen in gas condensate reservoirs.The study was done by presenting some methods to calculate these properties and the correcting of these values if there are nonhydrocarbon components in the condensate . the calculations were made by Stewartt methode and we put a computed program to calculate the correcting pseudocritical properties and noncorrecting ones, then we compear the tow values by drawing many diagrams between the mole fraction of the component and the calculated pseudocritical temperature and pressure.
This study includes an experimental work to determine the effect of ultraviolet radiation (uv-rays) on the mechanical behavior of the conveyor rubber vulcanizing, which used in various transport operations, and in the cement plant Tartus. In this wor
k, it has been prepared different samples of belts, and they were exposed to uv radiation at differente times, then they were tested to know its wear and tensile strength.
The results were compared with samples similar to the samples tested, which was not exposed to the rays of UV, and with other samples exposed to temperatures, and that in order to reach the ideal conditions for the use of these belts, which ensures longer period of use and safe conditions. This study showed that uv-rays increase the average of wear and the tensile strength of belts.
The effects of induction hardening on mechanical properties of two kinds of carbon
steel (0.59%C , 0.35%C) that are widely used in local industry, were discussed by exposed
specimens that were induction hardened with different values of power and i
nductor's
speed to hardness, tensile, and impact tests.
The results of tests showed that the mechanical properties become greater with slight
decrease in impact energy of carbon steel when induction hardening is used, and showed
the possibility to do control on product's properties by make control on treatment
parameters .
In this work composite hybrid materials were prepared from a base
material composed of epoxy and phenol - form aldehyde resins and
reinforced by 30% wt alumina and silica powders and asbestos
fibers. For samples were prepared with. Different ratio of
reinforcing material.
This research aims to decrease the cost of last production stages
through decreasing the cost of potential casing repair by avoiding the
problems that casing string may be exposed to. Such problems are
caused by the temperature effect of salt dril
ling fluids as well as other
fluids normally existed in the annular behind casing at the nonecemented
intervals.
