This project brought together the various services of Enerflex and presented a unique blend of challenges for the Enerflex team. Faced with adding to an existing facility, designing within an extremely small lease area, and achieving an aggressive delivery schedule, Enerflex undertook the supply and construction of a CO2 Removal Unit.
The facility is designed to remove carbon dioxide (CO2) from 235 million standard cubic feet per day of natural gas, utilizing a generic MDEA process. The major units consist of inlet flow distribution, inlet filtration, two identical three level processing trains (2 x 50% capacity), heat medium circulation, and a piperack with interconnecting piping to the battery limits.
CO2 Removal Unit
- Enerflex was responsible for coordinating the design of the site plot plan, each Amine train’s multi-level structural steel framework, the piperack and the interconnecting piping from the battery limits to each train.
- We fabricated and supplied the processing equipment in modularized packages.
- Enerflex managed the fabrication of major vessels and equipment, such as towers, coolers and some heat exchangers, which were subcontracted to Australian and Indonesian vendors.
- Logistics for the shipment of goods from Canada to Australia were also coordinated by Enerflex. The aggressive delivery schedule necessitated the early ocean shipment of the inlet modules and the Train 1 interconnecting piping, while the major modules for Train 1 were air freighted via an Antanov AN-124. With a staggered train start up schedule, the Train 2 equipment was ocean shipped.
- We were responsible for the construction of the CO2 Removal Plant, including civil, foundations, structural, mechanical and piping installation.
- Enerflex also supplied the structural steelwork for both trains and the piperack, as well as the piping for the piperack.
- Enerflex provided all the package electrical wiring, along with the DCS Functional Specification
- We provided on-site commissioning support, culminating in the successful startup and operation of Train 1 in October, 2005.
