Thank you TBP I got close to your figures with assuming 85% efficiency and with LHV of NG of 40591 KJ/kg. Cheers

Any quick estimate figure of how much fuel gas (ton) to produce 1 tone of HP steam (44 barg and 400 C). Fuel gas composition can be assumed to be 82.7 mol%C1,5 mol%C2, and 12 nol%N2 (I know that there is a way of finding heating value of the steam and calculate the required fuel fired but I...

Thank you all

I'd like to find out the price of the sphere (Mixed Butanes Sphere) with the following cases: 1- ID 19.2 m , Design Temperature=90 C, Design Pressure = 12.9 barg, Total volume = 3704m3 2- same as above except total volume is half (5o%) The Material is CS for both cases Any help or software can...

sshep It seems you have experience on this Can you give further explanation of your reply It is intended to send liquid ethylene from an atmospheric tank at -100C to a jetty at a port. The distance between the tank and the port is about 22km. What do suggest Thank you

I need to know from you if it is possible to send ethylene liquid at -100C with a 22 km pipeline. What are the difficulties and design requirements to be implemented to do this transfer. Thank you Best regards Libero

To jsummerfield There is no need for bypass for large expensive valve and in clean service. Therefore, if you got a problem in the valve, you will be forced to de-inventory the refrigeration system so you can work on the valve. This is the reason why a bypass is highly recommended to avoid above...

Think of on line monitoring by Metal Skin Temperature Transmitters that to be installed at the coil surface for measuring the skin metal temperature. Once the max metal temperature (Below Design Metal Temperature with some margin) is reached after sometime, you stop H2 feed. I have seen...

Tank you sms My question: Is it possible to provide bypass of a kickback valve installed for a compresor? Cheers

Montemayor, I'm trying to have general guidelines in which spare PSV is not required as the PSV can be taken off with no safety or operability concern. I will give some examples: - Thermal relief - Spare equipment - PCs provided in the system and can take the rated flow relief if some PSVs taken...

You would monitor metal skin temperature by pyrometer equipment that is used by operator thru peep doors of cracking heaters. Hope this would help

I'm evaluating the need of installed spare PSV for many PSVs for a plant under design development. Does anyone have experience in cases where installed PSV is provided to allow maintenance work of the other PSV? Any experience is more than welcome Cheers

I have discovered that no concern has been found of my worry of MDMT selected for some equipment. As per ASME and reference to one of the related references it has been found that the code gives much lower margin lower than the certified MDMT selected of an equipment and to a limit up to -105C...

I don't know if this is the right place to post a question with respect to the kickback lines of the centrifugal compressors. Does any one can share his experience in an application where bypass lines are provided for min flow recycles (Kickbacks) of a big centrifugal compressor for some...

You can check some applications in Medical factories where they might use such type of HEs.!! Cheers
