In February of 2024, a specialty chemical company in Pasadena, TX, reached out toZeeco regarding an upcoming fall turnaround. This turnaround would involve taking their flare system and associated instrumentation out of service for around 14 days to perform maintenance. This facility must follow the Refinery Sector Rule (RSR) emissions standards under NESHAP Subpart CC (40CFR §63.670). This rule requires many levels of instrumentation to monitor and record that flares are operating correctly and destroying the emissions being sent to the system. This customer wanted to bring in a temporary combustion and monitoring system that fully complies with the RSR during their turnaround.
임시 플레어는 다운스트림 석유화학 산업을 비롯한 많은 산업에서 유지보수 턴어라운드 중에 널리 사용됩니다. 석유화학 산업에서 이러한 시스템을 사용할 때 가장 큰 어려움은 다음과 같은 RSR에 명시된 계측 요구 사항입니다:
The facilities themselves also have many challenges with operating a temporary flare during turnaround activities. These include limited personnel and expertise in operating temporary combustion systems, available utilities, and plot space. It can also be difficult for facilities to navigate the regulations within RSR to ensure all components are accounted for during the turnaround.
Zeeco’s customer began by sending over the process design considerations of their existing flare system so Zeeco could take on all aspects of this project. This included supplying a temporary flare, all instrumentation, all temporary piping, all utilities, including power and instrument air, and all personnel to set up and operate the equipment during the planned shutdown.
The next step was to perform a full job walkdown of the project. Zeeco mobilized its Rentals and Global Field Services teams to visit the job site with the customer. The plant visit gave Zeeco valuable information about the plot space, flare tie-in points, and ensured all aspects of the project were covered. After the job-site visit, Zeeco confirmed the project scope and plan with the customer for the upcoming fall turnaround.
턴어라운드 기간 동안 Zeeco 고객의 요구 사항과 RSR 요구 사항을 충족하기 위해 여러 장비, 제어 및 계측기를 공급했습니다. 고객에게 공급된 장비에는 다음이 포함됩니다:
위의 장비 외에도 Zeeco 연소 전문 팀을 배치하여 턴어라운드 기간 동안 이 장비를 설치하고 완벽하게 운영했습니다.
By bringing in Zeeco to operate the temporary flare system and monitor the flare gas stream, the system was able to maintain above the necessary net heating value dilution (NHVdil) parameter required for refinery flaring. When operating above the required NHVdil number, the flare achieves acceptable destruction removal efficiency levels. Operating at a high efficiency for the duration of the turnaround meant that harmful chemicals were efficiently destroyed and turned into CO₂ and water vapor. Zeeco experts were able to keep the system operating with 100% uptime during the turnaround. This allowed the customer to focus on their maintenance activities, while Zeeco ensured they maintained their operations and remained environmentally compliant during the entire turnaround. Zeeco helped the customer execute a successful project while keeping them environmentally compliant and completing their turnaround on time.
