Dear LittleInch, The surge vessel operates between 1-3 psig. A utility gas is used to maintain the pressure and prevent vacuum within the vessel during pumping activities as the operation would be continuous. Like I said earlier, the vessel provide hold-up for the pipeline pumps. The oil...

Hi all, Please I need information on how to design a Produced Water surge Vessel. The original intent of the Produced Water Surge Vessel Design is to provide a hold-up volume for the pipeline pumps. The water inlet into the vessel is from the upstream Flotation cell and Skimmers. The Client...

Dear All, A produced water surge vessel is designed to collect treated produced water from the production platform before it is transported to the Water Injection platform via a dedicated PW pipeline pumps. Two pumps are designed to be operating simultaneously at 25,000 BWPD per pump (total...

Thanks littleInch and Artisi. am grateful. LittleInch, the answer to your comment is Yes. I am what I am by His grace

I am designing a pumping system that involves me providing the set point for the high and low pressure switch at the pump discharge? The pump operating discharge pressure for the pump is 110 psig. Is there a rule of thumb that can be used pending detail pump characteristic from the vendor to...

Thanks LittleInch, I appreciate your response. Am sorry for the double posting. I am what I am by His grace

Between bucket-type strainer and Y-type strainer, which is the best to be recommended to be installed at pump suction? I am what I am by His grace

Good day All, I am involved in a project whereby I need to transport a produced water from a flotation cell on a platform to another platform through a pipeline. The pumping system is designed to operate with a recirculation line for minimum flow protection of the pump. The operating pressure...

SJones, I am involve in a produced water project where I need to recommend either Carbon steel or Carbon Steel (NACE) for the service. I need to know the threshold required to determine whether a NACE material is required or not. I am what I am by His grace

Dear All, I am involved in a produced water disposal project, where we are transporting the facility produced water to a satellite water injection platform. Concerns where raised on the type of piping material to be used within the facility to the departing pipeline and whether to consider NACE...

I am involve in a project where we want to transport the produced water discharge from flotation cells through a pipeline to an injection platform. There are two flotation cells at the production platform and each working at atmospheric pressure and have a design pressure of 5 oz./in2...

Synchronization of the VFD pumps allow us to prevent oscillation on the discharge header/pipeline. I am what I am by His grace

Dear All, Please, I need advise on the type of pump that can be recommended to pump 2 liquids bulk flow (Oil + Water) from a platform to an onshore facility. I am what I am by His grace

They are centrifugal pumps. I am what I am by His grace

Good day All, I have two variable-speed pumps designed to be operate in parallel arrangement and discharge into a common manifold which is connected to a departing pipeline. They have different source of supply. Concern was raised on how to mitigate the effect of oscillations in the discharge...

Please, I want to know the steps taken in determining the blanket gas rate required for a vessel or tank. In my case, I am using a Fuel gas/HC gas as the blanket gas since it is readily available. I am what I am by His grace

Thanks all for your contributions. We have resolved to change the upstream LCV to an On/Off valve, thereby eradicating control valve operation from the pump suction. I am what I am by His grace

Dear All, Preview: An existing flotation cell is discharging its treated water overboard a platform. The water discharge outlet is controlled by a LCV which is operated by the LT on the unit. Now, it expected that the produced water is to be transported from the platform to another produced...
