Choosing the Right Pump
Choosing the Right Pump
(OP)
Any expert here in handling condensate.. I need some sort of pump that can safely handle a condensate on atmospheric pressure..its about 80 m3 per day capacity.

RE: Choosing the Right Pump
RE: Choosing the Right Pump
Certainly you are talking about API condensate (hydrocarbon) and not steam condensate??
Pumping API condensate is one of the most devilish services in a Refinery/petrochem plant; in part due to very low NPSH available at the pump suction. However, your saying you have atmosheric pressure doesn't sound like the conventional refinery condensate service. Maybe you just need condensate transfer in the field?? Still should be an API pump; could be centrifugal or positive displacement depending on your conditions.
Before suggesting a style of pump, should have a few more details from you, or estimates anyway.Could you describe the service a little more?
Flow is 80m3/day = approx 15gpm??
Discharge head/pressure required?
Suction conditions; atmospheric??
Specific gravity (can be in the .60s or lower)
Temperature (can be cryogenic)
RE: Choosing the Right Pump
We have existing oil and gas separation facility where we only flare some 100 mmscf/day of gas. Now some third party company is willing to take our gas (not until our own Gas Plant will be ready) they will compressed it and send back the condensate to us. the only facility where we can cater these condensate is our existing Closed drain tank which has Submersible pump then back to the system. This tank is just an atmospheric pressure with a capacity of 60 m3 our existing pump has a 50 m3/day capacity and discharged pressure of 7 Bar... Now I just wanted to changed this pump that is suitable to handle condensate..ideal pump must be economically sounds in term of spare parts.
RE: Choosing the Right Pump
Ambient temp might go to -20 Deg C during winter..(the worse so far)
RE: Choosing the Right Pump
Do you really need to pump 60 m3/day. Do you need 7 bar destination pressure?
2. Is the tank heated or placed underground?
3. Calculate DP_friction for the worst conditions (high viscosity, high density).

RE: Choosing the Right Pump
You need to move between 80-100 m3/hr (not m3/day as in orignal post right?)
Discharge pressure: 8Bar
Temp.: ambient, maybe down to 5C
Need a better feel for conditions at pump inlet; sump is open to atmosphere? If so, what is liquid level above pump suction during operation?
What is the S.G.?

I'm sure you realize how flammable condensate is.........are you sure it is open to the atmosphere?? Sounds crazy.
