SUCCESS STORY

 

Reduce seal leakage and nitrogen consumption with seal

replacements by EagleBurgmann

 

Region & Customer: USA – Hobbs, Major Midstream Company
Equipment: Dresser-Rand Datum Compressor Model D16R5S with Dresser-Rand Seals
Operating Conditions: Propylene Refrigeration Compressor

 

BACKGROUND
A midstream company was challenged by high nitrogen consumption and excessive process gas leakage. For this application, the nitrogen was supplied by truck to support the separation seal and secondary seals in a propylene refrigerant compressor. The high nitrogen consumption resulted in higher costs, and the high seal gas leakage from the dry gas seal resulted in recharging the refrigerant loop often.
 
CHALLENGE 
The customer was facing two issues:
  1. High consumption of nitrogen due to the seals and system design
  2. Excessive process gas seal leakage due to seal design.
​
​SOLUTION
EagleBurgmann installed DGS20-200-ZT7-L & DGS20-200-ZT8-R seals with modifications to the support system.
 
DGS20-200-ZT7-L & DGS20-200-ZT8-R:
  • 2 Tandem with intermediate labyrinth seals
  • Self-cleaning 3-D grooves
  • Low leakage seal (newer technology can reduce leakage even further)
  • Low nitrogen consumption separation seal
 
​Secondary Seal supply:
  • Convert to a flow control system reducing nitrogen consumption
 
STATUS
EagleBurgmann's DGS solution has been operating for 10 years with no issues:
  • Nitrogen consumption dropped from 60 SCFM to 6 SCFM
  • Nitrogen costs reduced by a factor of 10
  • Seal leakage reduced by 50%
  • Saves over 700,000 cubic feet of process gas per year due to lower seal leakage
