HI 

 

I want to know if there is a simulation software which enable me to simulate a Produced water treatment train containing CPI and IGF "induced gas flotation" and nut shell filters 

 

 

 

[Technical Bard]

No.  These are physical separations, not thermodynamic ones.  You can easily build your own calculation models from first principles for CPI separators.  You will need vendors for IGF and nutshell filters.

Is there any way to simulate these processes for sizing and calculating cost for beginning?

[thorium90]

You don't need to create a simulation of its operation to get its sizing and cost.

[eng.eslam87]

Okay then, is there any software to help me in estimating the cost and sizing...

 

I will really appreciate your help

 

thank you

Hi ,

the only way is to prepare the specification sheets with relevant balances for the vendors to size the equipments and provide a budget price .

 

Good luck

Out of curiosity, what is the purpose of this exercise? Are you building a new plant? Or is this just for better understanding of the existing plant?

[eng.eslam87]

i'm working in an old oilfield with only API separator to treat the produced water before disposal, and with the increased volume of the produced water, a new treating system is needed,, 

 

And i need something to help me to calculate equipment size and installation cost..... basically and roughly... 

 

Thank you 

[thorium90]

Sizing and costing, I would suggest you get someone more experienced to do or work with a vendor . For rough guidance, the following guide should be useful for you.

Please friends

 

can anyone help me with calculating the cost of the CPI, Hydro-cyclone, the nutshell filter?

 

I can't find any helpful data on the internet

hi ,

As I stated in a previous post you need to prepare  specification sheets to get quote from vendors ! Again if you want help from the forum members you should be specific .

We have no clue about your process , the flow rate ,the size , the material the equipment should be made of , etc  to give you a piece of advice .

 

Your filter should be a Nutsche filter !

 

Hope you understand and good luck..

sorry about the insufficient info Breizh

 

the produced water flow rate is  90,000 BPD 

the water analysis 

Oil and grease content

567  PPM

pH

6.35@ 25 oC

Total Dissolved Solids

148345.3 mg/l

Density

1.13069 g/ml @ 60 F

Total Suspendid Solids

139 mg/l

Specific gravity

1.13182

Conductivity

19.55 X10^-2 mohs/cm @ 23.4 ^oC

Hardness as CaCO3

21319.6 mg/l

Resistivity

0.0512 Ohm-m @ 23.4oC

Alkalinity as CaCO3

40.0 mg/l

Salinity as NaCl

148835.0 mg/l

 

 

It is required to reduce the oil content to less than 10 ppm 

and to reduce the suspended solids to less than 5 mg/l

 

It is required to install Two treatment train each consist of CPI followed by hydrocylone followed by a media filter " for example  walnut shell filter .." the design capacity for each train should be 50,000 BPD

 

i want to calculate the capital cost and the operational cost for this system..

 

your help is highly appreciated..

 

best regards

Hi,

Try to get a copy of the book in reference : gas-liquid and liquid-liquid separator by Maurice Stewart and Ken Arnold .

Hope this is going to put you in the right direction .

Good luck

With the WW info that you have just given, your proposed process of CPI, IGF and nut shell filters is definitely not suitable.

No offense, but you clearly do not have the info and expertise required to even select the correct process treatment, why are you being arrowed to do this?

If the plant does get built with what you have proposed, it would become a white elephant as the process clearly will not meet the treatment requirements.

If you are being arrowed for the task, I would suggest to find and work with someone with the required expertise.

 

I think the first step is for you is to do a proper wastewater characterization, then based on this wastewater information, come up with a design basis. From this design basis, come up with different possible process combinations and evaluate them. The evaluation should include the capability of achieving the treatment requirement. With the process flow scheme decided upon, you can then start to get budgetary quotations from vendors to help in your compilation of CAPEX costs.

 

You current proposed process will not be capable of meeting 10ppm oil and 5ppm TSS, so there is no point to go to the next step in calculating the CAPEX and OPEX of the system.
