Thanks George Verghese for your valuable feedback. i need to check on the 2-phase formation in the loop.

thread124-376699 System: Crude Tank Vapor Recovery Unit Compressor/HC Condensate Pump Discharge Coalescer in downstream of Condensate Pump discharge - for moisture/water removal before export to 35 km long pipeline with destination to a Gas Processing Plant Pump: 1000 psi discharge Pressure...

Thanks LittleInch for your feedback.

Existing Oil & Gas industry Produced Water Tank with Fuel Gas blanketing need to be provided with seal protection in the overflow lines. Sketch of the overflow lines is given in the attached worksheet. Kindly advice on the type of seal recommended for overflow lines...

Pardon me for the delay in reverting back to your queries. the 36" portion above ground near the tanks is now being shifted to below ground due to issue related to access area around tanks for cranes during maintenance. attached is a sketch showing the tank overflow lines connection to the...

thanks to all for your feedback which had the right & appropriate ideas for the issue I had.

Kindly share guidelines for tank overflow piping layout design

yes please produced water from tank first enters overflow pipes 24"/36" which then joins the 36" header. 36" header is above ground near the Tanks and goes below ground outside the Unit and all the way to Open Pits

Produced water overflow pipeline from many Tanks is routed to an Overflow Header which finally ends up in an Open Pit (for use during emergencies)in a existing Produced Water Handling Unit. Overflow pipeline from Tanks joins the header from below ground as shown in the attached simple sketch...

The barrel drain connection is being used to hook up water from portable tank for injecting water into the pipeline, hence the situation of drain valve & barrel isolation valve both being kept open.

Thank you all for the valuable feedback. MortenA's point is noted on the need to redo the steady & transient simulation runs. zdas04 "The pigging schedule ruled our lives since we treated the gathering system as our primary tool of reservoir management." 1. Do you mean here that Pigging...

Could you please guide if which type - Plant Air or Instrument Air, to be used in Liquid Sulphur Storage Tank and Liquid Sulphur Degassing Pit?

Preliminary design of Gas Gathering (100 mmsfd of high H2S (upto 10%) associated natural gas) includes piggable pipelines from different gas sources (50 psi) and joining Slug Cather followed by Gas Compressor (25 psi-suction pressure). But now pressure at gas sources are proposed to get lower at...

taking a pipeline for maintenanace, pigging with a batch of water and air/N2 is done to remove hydrocarbon content

Can anyone share tips on the design of closure door interlock mechanism. If the Pig Launcher / Receiver isolation valve is open, then barrel drain valve should be kept closed during normal pigging operation. But during special pigging operations like pigging with a batch of water and air, then...
