C3+ Bypass Program
The key feature of the C3+ bypass project was to maximize the C3+ throughput of an existing fractionation facility. The project also included receiving additional C3+ product, storing it and feeding it directly to the de-propanizer. Rangeland’s primary role was to maximize the throughput inside the fractionation towers, just downstream of the de-ethanizer of an existing fractionation train. Our services included the design, HAZOP/SIL and purchasing for all the equipment and associated facilities, including foundations, structures, building, piping, electrical, instrumentation and controls. Additionally, Rangeland designed the installation of a new flare system and MCC building to support this and future projects. A large portion of the equipment was located within a highly congested operating area, a common challenge to all brownfield projects.
The facility design includes:
•New asphaltene filter skid (including drain and filter back wash pumps)
•New C3+ feed heater, storage bullets and pumps
•New Flare System including knockout drum and flare stack
•Fire water supply
•Decommissioning of existing filter vessel
•Check of existing fractionation train (hydraulics, tower loading, reflux and condenser and reboiler)
As a brownfield project, Rangeland had a short window to shutdown; while the congested operating areas further challenged thetight construction schedule.
