While starting up the first turbine (turbine B), the turbine shut down on 1st stage high discharge temperature, triggering a flaring event. This was due to the 2nd stage discharge cooling fans not starting up in auto. The hot gas was recycling back to the first stage discharge. I&E personnel was called and they found blown fuses on both fans which were replaced and fans were started. On the next attempt to start B turbine, it shutdown on low hydraulic starter reservoir level. Turbine tech refilled reservoir and operators restarted turbine B. Upon restart, turbine shutdown on low hydraulic oil pressure. Turbine tech discovered a leak on the hydraulic starter system. It was decided to put turbine A online due to repairs needed on turbine B. While starting A turbine, it shutdown on low hydraulic starter reservoir level. Turbine tech refilled reservoir and operators restarted the turbine. Upon the restart, turbine A shut down on high compressor thrust vibrations. These issues resulted in the upset flaring event.

I&E personnel replaced bad fuses on Turbine B's second stage discharge cooling fans. Turbine tech filled the hydraulic fluid reservoirs on both turbines. Turbine tech repaired a leak on turbine B's hydraulic starter system. In between each turbine shutdown, all plant inlet were blocked in to reduce flaring. Turbine tech inspected the compressor of Turbine A and found no known cause for the thrust. Turbine tech gave the all clear to run the turbine A. Operators restarted turbine A with no further issues, ending the flaring event.

Several Targa compressor units on the Johnson low pressure system feeding the Johnson Processing Unit were down in the field which caused an increase in the low pressure inlet gas entering the Johnson Processing Unit. During this time, D-5 was shut down by the panel on low engine coolant level. The increase in inlet low pressure gas from the field, along with D-5 shut down at the facility, caused inlet gas to be routed to EPN FLARE-4 to protect the integrity of the pipeline and to keep the pipeline system protected from overpressure conditions which could cause other environmental incidents.

The Targa Overhaul Shop replaced the left bank gaskets and seals on D-5, and I/E repaired the vibration sensor on cylinder #4. Once the unit was restarted and the low pressure field pressure at the Johnson Processing Unit returned to normal operating parameters, the emission event ended.

Targa Pipeline Mid-Continent Westtex LLC utilizes a Microsoft Excel Spreadsheet to calculate Upset/Maintenance Emissions.

Upset Vent

Notrees booster shut down on high discharge pressure when the Goldsmith Plant lost turbine A due to dehy valve not switching as required. The field pressure increased and resulted in venting at the upstream booster.

The field operators asked the 3rd party gas producing customers to shut out gas in the field.

Tail Gas Incinerator

The mol-sieve dehy beds were not sending a signal to start a regen on the south bed. I&E was called to trouble shoot. While stepping the beds, a fuse in the PLC blew and caused all the valve to shut on the beds causing the turbines to shut down on High Discharge Pressure. This upset affected the normal operations of the Sulfur Recovery unit (SRU) and resulted in higher than permitted SO2 emissions.

I&E replaced fuse and corrected a loose wire. Operators restarted the plant and adjusted the operating parameters in the SRU to come back in compliance.

While stepping the beds, a fuse in the PLC blew and caused all the valve to shut on the beds causing the turbines to shut down on High Discharge Pressure. This upset affected the normal operations of the Sulfur Recovery unit (SRU) and resulted in higher than permitted SO2 emissions.

I&E replaced fuse and corrected a loose wire. Operators restarted the plant and adjusted the operating parameters in the SRU to come back in compliance.

Pressure Relief Valve

Due to high field pressure and other facilities, stations, and units on the common field pipeline system shutdown, pressure on the 9-Mile Compressor Station (CS) began to increase. To protect the station from overpressure conditions, inlet gas was routed to the PRV.

Once the field pressure began to decrease and the other facilities, stations, and units on the common field pipeline system restarted, pressure began to decrease on the 9-Mile CS and the emissions event ended.

Several Targa compressor units on the Johnson low pressure system feeding the Johnson Processing Unit were down in the field which caused an increase in the low pressure inlet gas entering the Johnson Processing Unit. During this time, D-11 was shut down by the panel on false low compressor oil level, D-9 was shut down by the panel on high resistance temperature detector (RTD) temperature, and D-5 was shut down by the panel on low engine coolant level. The increase in inlet low pressure gas from the field, along with 3 compressor units shut down at the facility, caused inlet gas to be routed to EPN FLARE-4 to protect the integrity of the pipeline and to keep the pipeline system protected from overpressure conditions which could cause other environmental incidents.

Targa Operations and Maintenance personnel worked as quickly and safely as possible to make repairs to the compressors that were shut down. Operations replaced the oil level switch on D-11 and then restarted the unit. D-9 was restarted once the RTD cooled down enough to restart, and the Targa Overhaul Shop replaced the right bank gaskets and seals on D-5. Once the units were restarted and the low pressure field pressure at the Johnson Processing Unit returned to normal operating parameters, the emission event ended.

EMISSIONS EVENT

RN102552031

Acid gas was routed to the flare during the facility commissioning activities during facility start-up. Gas was routed to flare in order to protect personnel and equipment.

Operations technicians worked through start-up/commissioning events and adjusted operational parameters. The emission event ended.

For each gas component, calculate Net Molecular Weight (MW):Net MW (lb/lb-mole) =Mole% o!Component/100 x MW of ComponentExample using propane: Net MW = 8.7522/100 x 44.10 lb/lb-mole = 3.86 lb/lb-mole.

The Ranger Compressor Station experienced high intake temperatures causing reduced compression throughout the facility. When the units had a reduction in compression, pressure on the field pipeline system increased above the pressure relief valve (PRV) setpoint causing the PRV to open and inlet gas was vented to the atmosphere.

Once Targa Maintenance made adjustments to the units and the intake temperatures decreased, all units returned to normal operations. Once the pressure on the field pipeline system decreased below the Ranger PRV setpoint, the PRV closed ending the emissions event.

Targa Pipeline Mid-Continent WestTex utilizes a Microsoft Excel Spreadsheet to calculate Upset/Maintenance Emissions. Up-to-Date representative gas analyses for each gas stream are maintained in the spreadsheet. Formulas Used in Reporting Table Below: Hydrocarbon Emissions (in Pounds)=[Process Stream Volume(SCF)X Mole% Component X Mole Weight of Component/385.4616]

Pressure Relief Valve

The Greenwood Compressor Station had multiple units shut down due to the ambient air temperature, causing pressure on the field pipeline system to increase above the pressure relief valve (PRV) setpoint and inlet gas was vented to the atmosphere.

Targa Maintenance inspected and began restarting the compressor units. Once the ambient air temperature decreased, all of the compressor units returned to normal operations, which caused the pressure on the field pipeline system to decrease below the PRV setpoint, ending the emissions event.
