Thanks all for the response. Ok, we are doing the feasibility study for the crude oil terminal and pumping system with pipeline across the country. I know in order to get the fairly accurate data for the PA (Plant Availability) is to perform RAM study, but we are at the early feasibility...

Hello my virtual friends and expertise! We are currently performing feasibility study for the crude oil storage tank terminal and pipeline. In the terminal there will be few storage tanks (more than 30) and a series of pumping station. The required no of pump is series is 13 nos (assuming all...

Hi It does depend on the pressure rating of your system. What normally we used, for liquid system having 600# and above, a double block and bleed valve is required. For gas system, for system having 900# and above, a double block and bleed valve is required. If H2S in the gas stream is high...

You can refer to many Chemical Engineering Thermodynamic book. You can also refer to Process Engineering Simulation model such as HYSYS Thermodynamic Base manual or PRO/II Technical reference data. thanks

Full Well Stream is the total wellfluid compositional data i.e. total wellfluid flowrate from particular well which consists total oil/condensate rate, gas rate and free water. Hope this help

Hi there... Does anybody know and have any experience on the Hydraulic Lift system for enhance recovery of the well? I know one of the method for enhance recovery is using Gas Lift, ESP, Gas Injection and water injection. Any source of info abt Hydraulic Lift system is highly appreciated. Thanks!

I need to know the standard available motor size in the market, used for the refinery and petrochemical industry. If possible I need to know the power factor and the efficiency (at full load) of such motor. Any help is highly appreciated. Thanks!!!

You can also refer to API RP 14E. It does give some equivalent length for the fittings.

sorry djwright Since your H2S is high (0.45 mole %) (NB: my previous H2S content is only 3500 ppm(v) and pressure is bit high than yours), then I would say that your fluid/gas service is fall under Class M fluid as per B31.3. Thanks

Hi there. I'm not mechanical engineer expert and not even mechanical engineer, but I've work on this fluid, with advise of my mechanical engineer last time. When I refer back to my latest B31.3 copy, and my previous work, one of the classification of class M fluid is having toxic gas in the...

Thermal expansion as a result of the blocked-in liquid exposed to the higher fluid operating temperature within the system. For example, blocked in liquid and expose to hot sunny condition. If the operating condition of the fluid is above hot sun condition, then it is not a problem, as the temp...

What's your operating pressure and the initial depressurisation pressure of your column? Thanks

Please be specific in your thread. There are various API and BS code for the various unit of operation, eg pumps have their own code of standard.

YS-1. A restriction orifice (RO) is normally be installed to limit the flow, instead of the depressurisation valve. In this case, the RO will be installed together with the blowdown valve (which will be actuated automatically upon detection of fire, or during ESD system). As mention by TD2K...

API 520 Part 1 latest revision (2000) Appendix D reveal the detail design calculation for the 2-phase relief scenario taking into account the omega factor etc.

Just wanna add to TD2K thread # 1. You can refer to the latest API RP 521 for the thermal relief of the block fluid (which include the cubical thermal expansion of the crude). Latest API RP 520 Part 1 has done major revision. API RP 521 will explain detail about the liquid thermal expansion...

Friends Generally, API RP 14E gives some recommendation insulation thickness for the personal protection (temp more than 65 Deg C?). It does depend on the line size and the temperature. Hope this help. Rusman rusman6800@yahoo.com

You need to model the simulation using isochoric flash (constant volume flash). As hilited by TD2K, since this is closed system, and your volume and mass is constant b4 your PSV is popped, then the density is constant. You need to model using Heat Exchanger module (I bet neither HYSYS not...

Folks NACE MR 0175 latest edition (2001) did explain the safe limit of various duplex stainless steel in cold annealed solution. For the normal duplex Stainless Steel 22Cr (UNS S31803) the safe limit of H2S partial pressure is limited up to 0.3 psia. If the partial pressure is higher, one must...

In sizing and selection of relief valve, you can refer to API RP 520 Part 1, and in the selection of the flange orifice relief valve, you can refer to API Std 526. The PSV is required to be installed on pressure vessel as per ASME Sect VIII Code or BS 5500 code. Thus we have to install PSV as a...
