Dear All,
While reading Mechanical Datasheet of existing Fired Heater package, We found that vendor/Manufacturer has taken ambient temperature 25C for Stack design and 50C for the rest of fired heater to design.
Please could someone explain to me what was the reason for these two different...
Hi
Thanks for this thoughts which are valuable for me. Especially Mr georgeverghese , your thoughts make things clearer.
What I think is that there is gas blowby from the reg KO drum when there is LT failure, this may cause knocking and hammering , hence line deformation. Because we notice...
Hi everybody
Thanks everybody for your technical approaches, but still give you more details for the damaged 2" line oily water in order to give more explanation of that phenomenon.
LV's and SDV valves are for level control of these drums.
Best regards...
Hi everyboy
I am process engineer in LPG plant. The oily water generated from regeneration phase of MolSiev bed of natural gas is sent from regeneration drum working @ 90bar & 50 to 60°C to API oily water treatement unit (Working pressure 1bar, ambient temp) passing by control valve through 2"...
Hi LittleInch
Firstly,I want to know basing on those flows of liquids, How can I estimate the slug volume.
Secondly, the size of Slugcatcher that I want to have is L<10m, D<3m.
Thanks
Hi everybody!
Mr Georgeverghese; If I got you, the 130m3 per hour arrives during 05 hours minimum, Not 130m3 over 05 hours.
Many thanks for you George & LittleInch
Hi
We have pipeline transporting Gas with MW of 24 to 25g/mol along the 130km, to LPG facility. Every three day, the CPF sending the gas to LPG plant, perform pigging operation. As the result, LPG plant receives a big quantity of cendensates about 130m3/h over 5 to 8hours.Please, I would like...
Hi
I entirely agree with you about CO (incomplete reaction of oxidation, but what about H2S.Is is possible that O2 reacts w/ sufides in normal conditions 1atm. and 30 - 35°C to produce H2S. If it is possible, I think it would be the SO2 as product not H2S.
Hi Don1980,
(sufide an inorganic anion of sulfur with the chemical formula S2− or a compound containing one or more S2− ions)
Is is possible that O2 reacts w/ sufides in normal conditions 1atm. and 30 - 35°C to produce H2S. If it is possible, I think it would be the SO2 as product not H2S.
Hi Don1980
Many thanks for your brief explanation ,sounds that's H2S doesn't previously exist in the process gas, it is the product of chemical reaction of O2 with sulfides adsorbed on Mosiev.
Hi
I am simukating in dynamic mode, but it doen't converge when simulating COMPONENT SPLITTERS in dynamics, has anyone a piece f information how to solve it
Hi don1980, thanks for your replying
We have followed UOP instructions for change out, but what I want , is possible scientific explanation of what happened.
Thanks
Hi!
I want to have an explanation for this phenomenon happened recently in our LPG dehydration section;
We are using UOP94 and UOP945 Mol Sieve A4. While trying to empty dryer vessel for changing a new UOP Mol sieve we had checked the the gases outlet from the dryer with Gas Tester before...
