Audits of Gas Operating Systems

Facility Evaluation-Colorado: GCC provided third party consulting to evaluate a new facility that was underperforming. Facility consisted of 2 @ 7044GSI/GE- Gemini packages producing 23 MMscf/d Dehy. GCC determined: 1. Compressor coolers were not sized correctly, 2. Compressor cylinders were not sized for correct conditions, 3. Engine was de-rating due to high ambient building temperature, 4. Engine was de-rating due to high water temperature, 5. Mufflers and cooler fans were not designed for proper dba limits, 6. Facility piping was not designed for correct gas velocity resulting in excessive pressure drops and noise, 7. Dehydration was not designed for high gas temperature resulting from undersized coolers. GCC corrections resulted in 6 MMscf/d increase and meeting state and federal emission and noise requirements.

Facility Evaluation-Utah: GCC provided third party consulting to evaluate eight (8) Cat 3516 purchased rental compressors at a facility that was underperforming. GCC determined: 1. Compressor suction controllers were not correct for facility. 2. Engine AFRC were not correct for application, 3. Remote air intakes would deliver 15% more engine power, 4. Original coolers were not sized correctly for elevation, 5. CO converters were needed to meet emissions. 6. Facility slug catchers and scrubber systems were not adequate, 7. Facility suction and discharge piping required an acoustical study. GCC corrections resulted in 20% increase in MMscf/d, improved run time and meeting emission requirements.

Facility Evaluation-Texas: GCC provided third party consulting to evaluate four (4) Cat 3600 compressors at a facility that was underperforming. GCC determined:
1. Compressor staging and cylinder loading was not correct for facility. 2. Suction controls were not optimized, 3. Engines were overheating due to outdated controls, 4. Poor foundation design was cracking piping. GCC corrections resulted in station increase of 17 MMscf/d.
