Project Synopsis
Troubleshoot and develop corrective measures for a gas processor who’s cryogenic natural gas trains where not meeting design throughput, had excessive liquid carryover, as well as smoking from the TEG reboiler burner stacks.
Project Summary
The client, an oil and gas mid-stream engineering company, contracted Process Engineering Associates, LLC, (PROCESS) to determine why their client (Salt Creek Midstream) was not able to achieve the design rate on two of the cryogenic natural gas trains in their production facility. Excessive liquid carryover had been observed from vent stacks in the TEG dehydration BTEX skid as well as smoking from the TEG reboiler burner stacks. The root cause of these issues was determined to be liquid hydrocarbon carryover from the amine treating system upstream of the TEG systems, aggravated by poor vapor-liquid separation at the BTEX skid and poor TEG system glycol health. Project tasks included,
- Multiple site visits to observe operations and collect operating data and equipment data, and to evaluate equipment and piping layout.
- Evaluation of glycol sample lab results.
- Evaluation of equipment sizing and capacity for adequate condensing and vapor/liquid separation.
- Issue report of investigation and conclusions with recommendations to improve operating practices, install properly sized separation equipment, and improve process controller tuning.
- Support of coalescing filter-separator design, procurement, and installation.
- Follow-up site visit to collect data after implementation of recommendations made as part of original assessment.
PROCESS issued a final report showing improvements made to the system with additional recommendations for further improved system performance.
