1 Case study Fluctuation of Seal Gas Supply Differential Pressure of Dry Gas Seals Rotating Equipment Engineer Qatargas Operating Company Sr. Rotating Equipment Engineer Qatargas Operating Company
2 Outline of Case Study Problem statement Compressor service overview Description of sealing system Problem description Troubleshooting Findings Remedial Actions Result Q & A
3 Problem Statement After commissioning of lean gas centrifugal compressors, Seal gas supply DP and flow to both ends of the compressor was fluctuating excessively Seal gas supply DP fluctuation was hitting DP low alarm Potential adverse impact on dry gas seal reliability and associated production loss Pulsations were temporarily controlled by pinching the root valve on the seal gas reference line
4 Installation Reference Qatargas is one of the world s largest LNG producing companies It operates four Lean LNG (LLNG) mega trains, each having a capacity of 7.8 MTA The mega trains were commissioned within the last 3-1/2 years Last train was commissioned in December 2010
5 Compressor Service Overview Lean gas compressor Compresses lean gas for feed to refrigeration section at constant discharge pressure Single suction centrifugal compressor driven by a extraction / condensing steam turbine Centrifugal compressor suction received from discharge of two upstream expander compressors
6 Description of Sealing System DGS s in tandem arrangement with intermediate N2 supply are installed on the compressor Primary seals are continuously supplied with filtered gas from the compressor discharge SG pressure is kept slightly higher than cavity pressure downstream of the balance drum Differential pressure controller controls the DP between SG cavity and SG supply pressures to maintain the required gas flow to dry gas seals
7 Description of Sealing System Seal Gas Supply Pressure Differential Controller PDC Pneumatic Control Valve Pressure Differential Transmitter PDT PT Reference Gas Steam ST C Extraction Condenser ASV
8 Problem Description 1. Seal gas supply pressure was fluctuating excessively (0.5bar 1.2bar) due to hunting of the differential pressure control valve 2. DP controller at the seal gas supply was fluctuating leading to item #1 3. Potential adverse impact on DGS reliability 4. Pulsations were temporarily damped (0.8bar-1.2bar) by pinching the root valve on the seal gas reference line
9 Problem Statement Seal Gas Supply Pressure Differential Controller PDC Pneumatic Control Valve Pressure Differential Transmitter PDT PT Reference Gas Steam ST C Extraction Condenser ASV
10 Troubleshooting DP fluctuation was persisting even when the control valve was on manual mode Possible causes of DP fluctuations Pressure fluctuations on seal gas reference line Pressure fluctuation on primary seal gas supply line Temporary arrangement was installed on the LP sensing line of the DP controller to obtain pressure trend on DCS
11 Troubleshooting Seal Gas Supply Pressure Differential Controller PDC Pneumatic Control Valve Pressure Differential Transmitter PDT PT Reference Gas Steam ST C Extraction Condenser ASV
12 Troubleshooting
13 Cause-Effect Analysis Process Instrument/Controls Suct./Disch. Pressure fluctuation Seal Gas Supply Pressure Fluctuations Seal Cavity Pressure Fluctuations Rotor Axial Movement Comp. Sealing System Pneumatic Control Valve Malfunctioning Pressure Differential Controller Tuning Inadequate Seal Gas Supply System Sizing Design Fluctuation of Seal Gas Supply DP Discarded Low Probability High Probability
14 Findings 1. Seal cavity pressure was fluctuating 2. Slight fluctuation in seal gas supply pressure was also present 3. As a result of item #1 & 2 seal gas DP was fluctuating Conclusion 1. Reference gas pressure pulsations were identified as root cause of the seal gas supply DP fluctuation 2. The DP fluctuations were attributed to process fluctuations
15 Remedial Actions Per OEM s recommendation after risk review: Self cleaning pulsation dampeners were added on both seal gas reference and seal gas supply tubes going to PDT Volume bottles were added on both the impulse tubes of pneumatic controller Purpose of adding pulsation dampeners and volume bottles was to dampen the pressure signals
16 Problem Resolution Seal Gas Supply Pressure Differential Controller Pressure Differential Transmitter Steam PDC PDT Reference Gas Pneumatic Control Valve Volume Bottles Pulsation Dampeners PT ST C Extraction Condenser ASV
17 Pulsation Dampening Hardware Self Cleaning Pulsation Dampener Volume Bottle
18 Results Proposed change implemented on compressor for trial purpose Trends were taken again to compare the change in pressure fluctuations Differential pressure control valve hunting minimized Differential pressure fluctuations reduced to acceptable level The reliability of dry gas sealing system improved Modification was also done on other similar compressors because of same issue of DP fluctuation
