API610 - Discussing Lateral Analysis of Pump Rotors

Assignment Task

Questions

1. There is a section in API 610 discussing requirement for lateral analysis of pump rotors. 

• What is this analysis about?
• Why is this analysis required?
• Can decision process for this analysis be improved? Please note that your answer must be based on at least two articles, preference is peer reviewed articles.

2. A centrifugal gas compression package is going to be used in an offshore gas processing plant. Pressure is going to be raised from 17 bar to 66 bar. 

a) The main parts of centrifugal gas compressor. Explain each part and its function.

b) Auxiliaries required for gas compressors (sealing system, lubrication system, cooling system and driver)

c) Minimum required systems for proper safety and control of this package.

3. A diesel engine (1800 rpm, efficiency: 30%) is going to be used as a driver for a high-capacity and pressure-reciprocating pump. The capacity of the pump is 350 m3 /hr and the maximum pressure is 120 bar. The speed of the pump is 200 rpm.

a) Propose two different power transmission methods for this package.

b) Briefly explain the technical details and specifications of them.

c) Briefly describe the pros/cons of these transmission methods

4. Prepare an report on four different types of seal plan recommended by API 682 which are used for centrifugal pump packages in oil and gas industry. In your report, describe the following:

a) Components of sealing system and required engineering inputs/limitations for them.

b) Brief review of their operation.

c) Their pros and cons.
