شناسایی مخاطرات در واحد 400 پالایشگاه گاز پارسیان. در این پروزه با بکارگیری از تکنیک hazop به شناسا یی مخاطرات ، انحرافات ممکن و در صورت لزوم ارایه راهکارهای مناسب جهت افزایش ایمنی فرا یند پرداخته میگردد. شرایط عملیاتی مخاطره آمیز نظیر فشار و دمای بالا و وجود ترکیبات مختلف سمی و قابل انفجار در واحدهای پالایش گاز، ضرورت توجه به موارد ایمنی در این چنین واحدهایی را مشخص می سازد. مطالعه hazop یک ر...
Hydrogen Detection with a TCD using Mixed Carrier Gas on the Agilent Micro GC
This application note highlights percentage level analysis of hydrogen on an Agilent Micro GC using a mixed carrier gas. Hydrogen is typically analyzed with argon carrier gas on a thermal conductivity detector. Argon however, will result in a decreased sensitivity for the other permanent gases. Helium carrier gas is, in most cases, also not a suitable alternative. Mixtures of helium and hydroge...

متن کاملMutual Friction and the Thermal Conductivity of Superfluid Helium Near
Temperature gradients in superfluid helium carrying a heat current in a 13.8-ram-wide tube or in a O.l-mm-wide slit have been measured at 0.09 m°K < T z T < 16 m°K. The results are interpreted in terms of a mutual friction force between the normal component of He II and vortices in its counterflowing superfluid component. This force is found to diverge near Tz with a mutual friction constant pr...
متن کاملThermal Analysis of Convective-Radiative Fin with Temperature-Dependent Thermal Conductivity Using Chebychev Spectral Collocation Method
In this paper, the Chebychev spectral collocation method is applied for the thermal analysis of convective-radiative straight fins with the temperature-dependent thermal conductivity. The developed heat transfer model was used to analyse the thermal performance, establish the optimum thermal design parameters, and also, investigate the effects of thermo-geometric parameters and thermal conducti...
