The understanding of the dynamic behavior of distillation columns has received considerable attention because distillation is one of the most widely used unit operations in chemical process industries. This paper reports a dynamic simulation study of the possible distillation columns sequences of Dew pointing unit in the second phase of South Pars Gas Refinery. In this unit, three columns are u...

OBJECTIVE We analyzed the clinical and radiologic features of posterior apophyseal ring separation (PARS) with lumbar disc herniation and suggest the proper management options according to the PARS characteristics. METHODS We reviewed case series of patients with PARS who underwent surgery of lumbar disc herniation. Preoperative symptoms, neurologic status, Body Mass Index, preoperative and p...

the establishment and development of industrial and free- trade zones have ever brought about a number of economic, commercial, and industrial benefits. the development of south pars special economic energy zone in the last decade, and following the policy of increasing efficiency in the common area with qatar, other aspects of economic development in kangan township have received little attent...

A numerical simulation for analysis and optimization of the performance NOx production was applied to a natural gas fuel boiler in South Pars Gas Complex. For this purpose, nine actual environmental operational parameters were measured recorded every two hours then averaged daily year. Using thermodynamic laws, important such as body exhaust flue losses, well thermal efficiency exergy efficienc...

Proteinase-activated receptors (PARs) are a four-member family of G protein-coupled defined by their irreversible proteolytic mechanism activation. PARs have emerged as important regulators various physiological responses and implicated in numerous pathological conditions. Importantly, PAR1 PAR4 critical platelet function, while PAR2 is well established driver inflammatory responses. PAR-target...

Withdrawal of oil and gas from reservoirs causes a decrease in pore pressure and an increase in effective stress which results to a reservoir compaction. Reservoir compaction will result in surface subsidence through the elastic response of the subsurface. Usually in order to determine the subsidence above a hydrocarbon field, the reservoir compaction must be first calculated and then the effec...

Hydrocarbon Processing Industries (HPIs) emit large amounts of highly reactive hydrocarbons and Nitrogen Oxides to the atmosphere. Such simultaneous emissions of ozone precursors result in rapid and high yields ozone (O3) formation downwind. The climate of the Middle East has been shown to be favorable for O3 formation in summer. There are also vast activities in processing oil and gas in this ...

Heterogeneous photocatalytic degradation of Polynuclear Aromatic Hydrocarbons (PAHs) contaminated soil in the Pars Economic and Energy Zone was carried out <span style="font-size: 10pt; color: #000000;...
