EMISSIONS EVENT

Liquefaction Flare

LIQFLARE

NSR Permit Number 100114

During operation of Freeport LNG's Liquefaction Plant, Liquefaction Train 1 experienced two trips that resulted in unavoidable venting to the Liquefaction Flare (LIQFLARE). Although initially considered and reported as one occurrence, a more detailed examination of this event indicates there were two contributing events. The first trip occurred at 9:27 am. This inadvertent trip was due to routine maintenance on lube oil pumps on the Main Refrigerant Compressor. Shortly after the unit was brought back online, a second trip occurred at 16:34 pm, caused by a failure of the stem on a flow control valve. Subsequent flaring occurred with the startup and cooldown of the unit as Train 1 was brought back to operating temperatures that would allow for the cessation of flaring. This Final Report is for the sum of air emissions for both events.

The plant operators and maintenance personnel acted to resolve the causative issues and initiated the re-start and cooldown of Train 1 as quickly and efficiently as possible to minimize flaring. Vent gas emissions during this event were routed to the LQF Flare for emissions control.

The emissions estimates were based on the volume and composition of the vent streams to the Liquefaction Flare for the duration of this event. For example, the emissions to the flare were based on the total MMscf vented x the fraction of each air contaminant in the vent stream multiplied by the appropriate flare destruction efficiency and unit conversions to determine the total pounds vented. For venting to the flare; NOx and CO emissions were based on the total stream flow (total MMscf), converting to MMBtu (LHV) and multiplying by the TCEQ emission factor for NOx/CO emissions from flares. The VOC emissions estimate assumed a 99% destruction efficiency for propane and ethylene and 98% destruction efficiency for C4+ compounds present in the gas stream.

After re-evaluation of this emissions event, it was determined that emissions from this flaring event were not equal to or did not exceed a Reportable Quantity as defined in 30 TAC 101.1(89) and therefore, this is considered a non-reportable emissions event as defined in 30 TAC 101.1(72).

The plant operators acted to resolve the electrical wiring issue and initiated the startup and cooldown of Train 2 as quickly and efficiently as possible to minimize flaring. Vent gas emissions during this event were routed to the LQF Flare for emissions control.

The emissions estimates were based on the volume and composition of the vent streams to the Liquefaction Flare for the duration of this event. For example, the emissions to the flare were based on the total MMscf vented x the fraction of each air contaminant in the vent stream multiplied by the appropriate flare destruction efficiency and unit conversions to determine the total pounds vented. For venting to the flare; NOx and CO emissions were based on the total stream flow (total MMscf), converting to MMBtu (LHV) and multiplying by the TCEQ emission factor for NOx/CO emissions from flares. The VOC emissions estimate assumed a 99% destruction efficiency for propane and ethylene and 98% destruction efficiency for C4+ compounds present in the gas stream.

LIQFLARE

NSR Permit Number 100114

During operation of Freeport LNG’s Liquefaction Plant, the Liquefaction Train 2 experienced a trip of the compressors variable fan drive network bridge fault. This resulted in unavoidable venting to the Liquefaction Flare (LIQFLARE). Ongoing flaring occurred with the startup and cooldown of the unit as Train 2 was brought back to operating temperatures that allowed for the cessation of flaring.

The plant operators acted to resolve the bridge fault, bring the compressor back on-line, and initiate the startup and cooldown of Train 2 as quickly and efficiently as possible to minimize flaring. Vent gas emissions during this event were routed to the LQF Flare for emissions control.

The emissions estimates were based on the volume and composition of the vent streams to the Liquefaction Flare for the duration of this event. For example, the emissions to the flare were based on the total MMscf vented x the fraction of each air contaminant in the vent stream multiplied by the appropriate flare destruction efficiency and unit conversions to determine the total pounds vented. For venting to the flare; NOx and CO emissions were based on the total stream flow (total MMscf), converting to MMBtu (LHV) and multiplying by the TCEQ emission factor for NOx/CO emissions from flares. The VOC emissions estimate assumed a 99% destruction efficiency for propane and ethylene and 98% destruction efficiency for C4+ compounds present in the gas stream.

The plant operators acted to resolve the power issue, restore power and initiate the startup and cooldown of the liquefaction trains as quickly and efficiently as possible to minimize flaring. Vent gas emissions during this event were routed to the LQF Flare for emissions control.

The emissions estimates were based on the volume and composition of the vent streams to the Liquefaction Flare for the duration of this event. For example, the emissions to the flare were based on the total MMscf vented x the fraction of each air contaminant in the vent stream multiplied by the appropriate flare destruction efficiency and unit conversions to determine the total pounds vented. For venting to the flare; NOx and CO emissions were based on the total stream flow (total MMscf), converting to MMBtu (LHV) and multiplying by the TCEQ emission factor for NOx/CO emissions from flares. The VOC emissions estimate assumed a 99% destruction efficiency for propane and ethylene and 98% destruction efficiency for C4+ compounds present in the gas stream.

During operation of Freeport LNG’s Liquefaction Plant, the Liquefaction Train 2 experienced a trip due to a trip of the 12K-31 Low Pressure Mixed Refrigerant (LP MR) Compressor. This resulted in unavoidable venting to the Liquefaction Flare (LIQFLARE). Ongoing flaring occurred with the startup and cooldown of the unit as Train 2 was brought back to operating temperatures that allowed for the cessation of flaring.

The plant operators acted to resolve this issue, bring the LP MR compressor back on-line, and initiate the startup and cooldown of Train 2 as quickly and efficiently as possible to minimize flaring. Vent gas emissions during the startup were routed to the LQF Flare for emissions control.

The emissions estimates were based on the volume and composition of the vent streams to the Liquefaction Flare for the duration of this event. For example, the emissions to the flare were based on the total MMscf vented x the fraction of each air contaminant in the vent stream multiplied by the appropriate flare destruction efficiency and unit conversions to determine the total pounds vented. For venting to the flare; NOx and CO emissions were based on the total stream flow (total MMscf), converting to MMBtu (LHV) and multiplying by the TCEQ emission factor for NOx/CO emissions from flares. The VOC emissions estimate assumed a 99% destruction efficiency for propane and ethylene and 98% destruction efficiency for C4+ compounds present in the gas stream.

NSR Permit Number 100114

This is a second retraction due to a clerical error. This is a re-submittal due to a change of anticipated start date. This is to provide notice of anticipated flaring to Freeport LNG's Liquefaction Plant (LQF) flare (LIQFLARE) due to the restart of Train 1 after the Train has been shutdown due to a recent trip that occurred on October 21, 2020. The re-start will include the restart of the 11K-31 compressor system and the cooldown of the Main Cryogenic Heat Exchanger (MCHE) and its downstream LNG transfer systems. The re-start and cooldown of the unit will result in venting to the Liquefaction Flare (LIQFLARE) until the MCHE is brought back to nominal operating temperatures and stable operation of Train 1 is achieved.

The LQF operators will proceed through startup in a controlled and efficient manner to minimize flaring. Vent gas emissions during this startup will be routed to the LQF Flare for emissions control. Once the MCHE is brought back to nominal operating temperatures and stable operation of Train 1 is achieved, venting to the flare from this event will cease.

The emissions estimates were based on the volume and composition of the vent streams to the Liquefaction Flare for the duration of this event. For example, the emissions to the flare were based on the total MMscf vented x the fraction of each air contaminant in the vent stream multiplied by the appropriate flare destruction efficiency and unit conversions to determine the total pounds vented. For venting to the flare; NOx and CO emissions were based on the total stream flow (total MMscf), converting to MMBtu (LHV) and multiplying by the TCEQ emission factor for NOx/CO emissions from flares. The VOC emissions estimate assumed a 99% destruction efficiency for propane and ethylene and 98%destruction efficiency for C4+ compounds present in the gas stream.
