Project Name: Flow capacity calculation of the tar oil pipeline

Company Name: Gazprom Neftekhim Salavat LLC

Project Description

Region Republic of Bashkortostan, Russian Federation
Dates 2019
Scope The company had to determine the reasons why the volume of tar oil pumped through the pipeline was lower in comparison to the calculated one.
The analysis task was to determine the initial pressure and flow rate in the existing tar oil pipeline.
Project Specific

The tar oil is pumped from the tankage facilities to the Bitumen Production Unit and is used as raw material for bitumen production.

How PASS software helped in the project execution

The analysis was performed for the existing pipeline consisting of a large number of small parts with multiple changes of diameters.

Manual calculations would cause the following issues:

  1. Dramatically increased time required for analysis.
  2. Limited to approximate results, which would not allow to determine the real reason of the reduced tar oil volume.

To ensure high accuracy of analysis and a reduced project execution period, the company used PASS/ HYDROSYSTEM software.

During analysis, it turned out that the fluid temperature was dropping along the line, and as a result, fluid viscosity increased and the flow rate was lower than required.

Results The performed analysis made it possible to find the real reasons, take timely measures to normalize the volume of pumped tar oil and meet the customer’s project schedule.
