Mechanical seal and API Plan for desalted Crude Oil centrifugal pumps (Temperature: 150ºC)

Mechanical seal and API Plan for desalted Crude Oil centrifugal pumps (Temperature: 150ºC)

Mechanical seal and API Plan for desalted Crude Oil centrifugal pumps (Temperature: 150ºC)

(OP)
Dear all,
I would like to know, based on your experience, which is the best seal (configuration) and API Plan for Crude Oil sealing.

The service is desalted Crude Oil at suction conditions = 150ºC and 9.5 kg/cm2 (discharge pressure = 38 kg/cm2), centrifugal pump between bearings (United Pumps DVS type)

Our MTBR, with single seal metal bellows and API Plan 11 is very poor, in fact the seal always leak but depending on the crude oil processed the leakage is greater.

Any thoughts, ideas and recommendations will be very welcomed

RE: Mechanical seal and API Plan for desalted Crude Oil centrifugal pumps (Temperature: 150ºC)

PLan2361 would work

A well phrased question has answers in itself!!!

RE: Mechanical seal and API Plan for desalted Crude Oil centrifugal pumps (Temperature: 150ºC)

Plan 11 will not work as the temperature is above 80degC

A well phrased question has answers in itself!!!

RE: Mechanical seal and API Plan for desalted Crude Oil centrifugal pumps (Temperature: 150ºC)

For this temperature Pusher Type seal also will work better.
Since pump condition is not known , I suggest to go for Stationary Pusher Type seal.

RE: Mechanical seal and API Plan for desalted Crude Oil centrifugal pumps (Temperature: 150ºC)

Go for pressurized double mechanical seal (53B)

RE: Mechanical seal and API Plan for desalted Crude Oil centrifugal pumps (Temperature: 150ºC)

Dear Mukesh

How can 53b be employed. First we want to know whether there is presence of H2s more than 200 ppm?
Why not suggest plan 2352.

A well phrased question has answers in itself!!!

White Paper - The Criticality of the E/E Architecture
Modern vehicles are highly sophisticated systems incorporating electrical, electronic, software and mechanical components. Mechanical systems are giving way to advanced software and electronic devices, driving automakers to innovate and differentiate their vehicles via the electric and electronic (E/E) architecture. As the pace of change accelerates, automotive companies need to evolve their development processes to deliver and maximize the value of these architectures. Download Now
White Paper - Model Based Engineering for Wire Harness Manufacturing
Modern cars, trucks, and other vehicles feature an ever-increasing number of sophisticated electrical and electronic features, placing a larger burden on the wiring harness that enables these new features. As complexity rises, current harness manufacturing methods are struggling to keep pace due to manual data exchanges and the inability to capture tribal knowledge. A model-based wire harness manufacturing engineering flow automates data exchange and captures tribal knowledge through design rules to help harness manufacturers improve harness quality and boost efficiency.

White Paper - Modeling and Optimizing Wire Harness Costs for Variation Complexity
This paper will focus on the quantification of the complexity related costs in harness variations in order to model them, allowing automated algorithms to optimize for these costs. A number of real world examples will be provided as well. Since no two businesses are alike, it is the aim of this paper to provide the foundational knowledge and methodology so the reader can assess their own business to model how variation complexity costs affect their business.
