Hi everyone, We need to design supply and return pipelines from one plant to another plants in order to use existing package in second plant.package will be used occasionally by Only one of two plants. Because source of liquid is storage tank in first plant ,there is not any concern in designing...

Hi everyone; we are going to transfer chemical from storage tank trough pump and pipe line to another plant.maximum flowrate is dictated by downstream plant and it is clear. i need to define normal flowrate because i need it for calculation and also to put it in equipment and instrumentation...

Hi all I am looking for some criteria for velocity and pressure drop/100m for MEG in order to perform line sizing for MEG line and pipeline. I know general criteria for liquids such as what mentioned in TOTAL or others standards, but winteresting thing for me is special criteria for MEG ...

I am going to size a centrifugal pump to transfer liquid from one plant to another plant through 2 km pipeline. maximum flowrate which could be transfered by pipeline is limited by downstream plant and is around 40 m3/hr. since maximum flowrate is fixed , i am not sure that is it still required...

Dear Friends; I am not sure that whether here is a right forum to ask my question or not.If not ,please move this topic to relevant section. I want to know how can I model a piping system between two closed valves(shutdown valve) which in case of fire is being pressurized by fire.Indeed I want...

Dear Friends; As you know in case of fire occurrence on platform; it is necessary to consider an appropriate time delay to ensure that Emergency shutdown valves(ESDVs) are closed before Blowdown valves are opened to prevent any problem like flare overloading. I want to know how much the required...

Hi I want to prepare a report about the fundamentals which helps to determine the best position for QA department in company organization chart( specially oil and gas companies or some examples of oil and gas company's organization chart). could you please introduce me standard, paper or any...

I am going to simulate a gas sweetening unit which utilizes DEA and MDEA as solvent. I am looking for some shortcut and rules of thumbs methods for specifying key parameters such as number of trays for absorber and regenerator columns,reboiler duty,circulation rate,... please let me know if...

Hello I was asked to prepared a report regarding comparison between two type of deaerators,the tray-type (also called the cascade-type) and spray-type deaerators. Can anybody refer me to a guideline or book or any other reference which includes some topics regarding advantages, disadvantages and...

Hi I want to know the criteria for selection of silica gel or molecular sieve for dehydration of gas. what are advantages and disadvantages of each process in design,operation and cost standpoints.

Hi I want to know which software(Pipephase or OLGA)is more reliable for simulation of a onshore-offshore pipeline with 25 km length which transmit 3 phases GAS stream. what is the limitations , PROs and CONs for each one.

friends; Can anybody guide me to a good reference(tutorial) for OLGA and PVTSIM?

the concern is regarding sizing a PSV for fire case for Glycol Cooler in Glycol Regeneration Package. Data is as below: 1-PSV set pressure=10 barg 2-glycol cooler inlet conditions:temp=73 c,pressure=6.3 bar 3-glycol cooler outlet conditions:temp=37 c,pressure 5.8 bar 4-wetted surface area...

I want to know how can I calculate Z factor for natural gas including c1-c5 and c6+ to c+20 cuts and also H2S and CO2. I tried to use HYSYS but the Z factor field is empty. Is there somebody to explain the method for such calculation in HYSYS or any other method or reference for such cases.
