Thanks. Actually this holdup is calculated from Pipesim (SS run) and it calculates volume only. It don't tell accumulation rate and that's what I am looking for to avoid dynamic simulation at this time. I need to know how much pigging frequency should be considered in selection of slug catcher...

Hi Everyone, I am working on Gas condensate pipelines and need support to solve one problem. Brief description:- The 12” pipeline system has lot of NGL in the flowing gas stream, and Pipesim is predicting dropout of the liquid. The gas stream is saturated leaving the 2-phase separator at a...

I need to know how RVP of Gasoline is converted to TVP. Gasoline RVP at 100 deg F is 9.0psia (for summer) and at 60Deg F is 11.5psia (for winter. How these RVP values will be converted to TVP. Can we convert 100deg F RVP to TVP at 100deg F and 60deg F RVP value to 60deg F TVP value? Is there...

I will add that system includes all protections like low suction pressure, high flow, high high discharge pressure and recycle control valves. the only issue is that how we can avoid pump to reach end of curve during shifting time from recycle to operating mode without shutting down the pump. If...

Hi all I need your expert feedback on below problem. This is related to newly installed pump station on the cross country pipeline. One new pump station with three pumps are installed mid way of existing cross country 1200 km pipeline. Pumps are going to commission. We are worried that during...

Hi to all. Can some one tell which Hysys property package can be used for following fluids; 1- Water/Sea Water 2- Air 3- Nitrogen

Is there any one who can help to provide calcualtion procedures for verticle vaporizer.Liquid N2 will be used on tube side of vaporizer and water on out side of tubes. How vaporizer can designed for this application. Help out on this please.

Thx. I thnk option to use LNG vaporizer is quite feasible. Is there any one who have calculation procedure for verticle vaporizer. Help out on this plese.

cost is secondary thing, we looking for some sort of temporary as well as permanent solutions.

Pump is fixed speed and pump is delivering pressure at low flow but pipe line is not seeing that pressue as no back pressure in line and large size of line very less pressure drop in line at low flow.

I need some urgent help on below problem. One crude 100km,36in pipeline is design to handle 500MBOD flwo rate with line pressure drop of 224psi. At start up line there is centrifugal pump with no discharge control valve delivering 270psig required inlet pressure. At the moment problem is how to...

Thx gr2. Actually this is existing facility and existing intercoolers (2+1) are not compatible for cryogenic conditions. That's why we hace to cool sea water going to intercoolers. Sea water can be cooled in S&T type HE or in vaporizer as other options like using glycol or mixture of water &...

It is true that glycol is better option. But it will add one new exchanger and economically it is not advisable as this is existing sea water treatment plant which is producing excess liquid N2 which they want to use to cool sea water being used in the inter cooler of air compressor. Therfore...

Hi I am new member and want to discuss one process development problem. We are in the phase of developing some type of process to utilize excess liquid nitrogen to cool utility water. Can liquid nitogen be used to cool water from 110 degF to 41 degF in S&T type Heat Exchanger? Due to very low...
