في هذا البحث تم دراسة تحسين عملية فصل الماء و الأملاح عن النفط في شركة حيان للنفط من خلال تحديد معدل الحقن المناسب لمادة مانع الاستحلاب و معدل ماء الغسيل المستخدم و تخفيف التركيز الملحي لتيار الماء الراجع إلى المرحلة الأولى لعملية الفصل و زيادة زمن البقاء في فاصل نازع الأملاح و ذلك تبعا لطبيعة النفط المدروس و شروط العملية و مواصفات النفط المطلوبة.
In this research we improve the desalting process by determine the perfect value of demulsifier and washing water flow rate , reducing the salts concentration of separated water current going to first stage desalting and increasing residence time of oil into desalter according to the characteristic of oil and the process condition.

In this research study the effect of the type of corrosion protection, on the rates of Carbon Steel samples from the same metal tube oil buried in soil and comparing between corrosion rates of samples steel non protected and corrosion rates protected
samples in different protections ways, protection paint epoxy,
protection paint epoxy and polyethylene and Cathodic protection
by sacrifice anode (Zinc was chosen as anode sacrifice) and
Cathodic protection impressed current.
The samples protected and non-protected study's in the middle of
corrosion of two sites of Homs soil (soil city of Homs –soil of
Furqlus area) In each soil alone and the statement of the
effectiveness of the Cathodic protection in increase the protection
and then the comparison between the two Cathodic protection to
reduce the corrosion rate was also study the effect of humidity and time on the corrosion samples steel is protected and samples steel Cathodic protected rates by anode sacrifice and was finally
comparison between rates corrosion between the signatories
studied soils (soil city of Homs - soil of Furqlus area) and
whichever is more aggressive and study the factors that have
made the soil more Furqlus hostile soil of the city of Homs,
prompting us to both soils analysis and study results.
The aim of this study is to highlight the potential use of marine algae as well as polypropylene for the removal of crude oil from surface seawater.
The determination of optimal sorption time and sorption capacity of the materials in oil/water bath
and oil bath without water in presence of three oils of different viscosity were investigated. The capacity of oil removal from seawater was related to structure and surface properties as well as oil amount and oil properties especially, its viscosity.
The results revealed that the extension of absorption time does not influence absorption capacity of the examined sorbents in presence of both oils of low and middle viscosity (LV and MV). Nevertheless, the sorption capacity was increased by extending the absorption time to 30 min. For high viscose oil (HV). The sorption capabilities of Enteromorpha exceeded those observed for all of the other algae, while polypropylene fiber showed the highest capacity. Overall, the sorption capacity of the studied sorbents increased with increasing oil viscosity. The absorption capacities of studied materials in the oil bath and oil/water bath were comparable.
The results suggested that substitution of synthetic oil sorbents used in Syria by marine algae is possible in oil removal, which have relatively high sorption capacity.
Uncontrolled disposal of produced water from oil and gas industry in the
environment involves the environmental hazard like contamination soil by NORM and
increase the radiation exposure to terrestrial gamma radiation by workers and public. the
st
udy aims to measure radiation levels in the drainage zone and vicinity in the field of
crude oil storage tanks in the site of Syrian company for oil transport in Banyas. Terrestrial
gamma radiation dose was measured, the values ranged between 0.02 – 0.24 μSv.h-1. The
radioactivity concentrations of NORM were determined for Ra226, Th232, K40 by gamma
spectroscopy using HPGe detector in surface soil samples taken from three sites, two of
them recorded the highest rate of radiation dose, while the third recorded the rate of
radiation background. The Ra226, K40, Th232highestconcentrations in the soil samples were
found to be 210, 213 and 55.9 Bq.kg-1, respectively. Radiation indexes were estimated.
The present results were compared with results published in different countries.
In this research proposed system components will be studied in
order to recover flare gases at outstations of the oil fields which not
connected to any gas plant, hence they send continuously the entire
associated gases to the flare, and how to de
termine the proposed
recovery system operating parameters in order to recover the
mentioned gases and reuse them in central process facilities, where
a number of gas turbines which have a dual system (gas - diesel)
located at Elwared central process facility consume a huge amount
of diesel, while the associated gas in Elwared related outstations
especially Elahmar burns (2.5 MMSCFD).
The "Middle East" is one of the most tense regions of the world, and these tensions linked mainly to the existence of the Zionist entity as an outside intity cruel implanted in the heart of the region, and which seeks to exploit and steal any land a
nd wealth lies in his hands.
And with the discoveries of reserves the vast gas and oil in the levant basin escalated tensions in the region after Israeli efforts to exploit these reserves and stealing these resourses without taking and this led to the outbreak of differences bilateral and multilateral conflicts of interests among the countries in the region which allows Israel to play a key role in these issues, especially the Lebanese – Israeli conflict ,the Turkish – Cyprios case which Israel is third party in such conflicts.
