Project to collect, process, and dispose of refinery flare emissions. Added new flare to allow fexibility of turnaround scheduling and unit isolation. Reconfigured Flare Vapor Recovery compressors and multiple units to use refinery gas. Interconnected new and upgraded several units with existing refinery units. 

Anvil provided full Engineering, Design, Procurement, and Field Construction Support services within the clients phased project execution process, including:

• Develop project package
• Develop TIC Estimates for each unit
• Complete engineering and detailed design
• Procure material and equipment
• Work with Client and Construction Contractor on construction planning
• Support construction in the field

New Units

• Flare Vapor Recovery System
• Sour Water Stripper
• Amine Unit

Expand an existing facility to add low sulfur diesel to its refinery products, while continuing to produce jet fuel, diesel, and kerosene at an Alaska facility. The project installed a DHT Unit, Hydrogen Plant, and Sulfur Recovery Unit. 

Anvil completed the OSBL services required to integrate and install the new units into the existing refinery. We worked closely with the ISBL equipment engineers and fabricators. to coordinate the interfaces.

Anvil provided a multi-discipline effort to support the OSBL work, including Procurement, through project definition, execution, and construction. 

• Developed engineering and cost estimates
• Developed work packaging structure
• Provided definition and detailed design services for all OSBL equipment
• Provided on-site Construction Coordination and Field Services during pre-turnaround, turnaround, and startup.

Project Highlights

Due to severe weather conditions and a short construction season, all package deliverables were schedule-driven and equipment was installed and connected over two summer construction seasons. 

Install a new Isomerization Complex to meet or exceed anticipated future clean gasoline specifications, and provide an alternative to using MTBE to product CARB 3 gasoline.
Anvil provided full Engineering and Design, and Construction Support services-from early conceptual design through startup, including:

• Conceptual engineering and cost estimating services
• Definition and detailed design services for the selected project
• On-site Field Services during pre-turnaround, turnaround, and startup.

Anvil's OBL Scope

• Modify existing process units and utilities to integrate new unit
• Connect piping, controls, and power to new ISOM unit
• Cooperate closely with IBL engineer

Scope Highlights

• 45,000 feet of pipe
• 228 tie-ins with 13 hot taps
• Design ~350 tons of steel
• 1,000 cubic yards of concrete

Install a new grassroots 18 kbpd Diesel Hydrotreater (DHDS) to meet required ultra low sulfur diesel specifications.  The unit will treat 5,000 ppm high sulfur diesel to produce diesel with less than 15 ppm sulfur. 

Anvil provided full Engineering, Design, and Construction Support services-from early conceptual design through startup, including:

• Conceptual engineering and cost estimating services
• Definition and detailed design services
• On-site Field Services during pre-turnaround, turnaround, and startup.

Anvil's OBL Scope

• Cooperate closely with IBL engineer
• Provide on-line blending and certification capability. Provide product piping logistics to allow the blender operators to manage three separate grades of diesel fuel.
• Install interconnecting piping to support unit installation.
• Modify the Sour Water Strippers to accommodate additional sour water.
• Provide DCS infrastructure to support new unit.

Project Highlights

• 41,000 feet of pipe
• 77 tons of steel
• 340 cubic yards of concrete
• 8,600 feet of conduit

Project to split the cat-cracked gasoline into 2 products suitable for effective sulfur removal:

• Light cat gasoline, which is treated in a Mercaptan Extraction Unit
• Heavy cat gasoline, containing the majority of the combined sulfur, is desulfurized using a proprietary fixed bed catalytic process in a new Heavy Cat Gasoline (HCG) HDS Unit. 

Anvil provided full engineering and design services for the project's design and construction phases.  Additional services included:

• Procure equipment and long lead bulk materials
• Develop a quantity-based funding estimate, divided by subsystems and disciplines, to compare and track actual to estimated materials.
• Track cost during the construction phase

Project Highlights

• Added new equipment to an existing process unit with limited space and highly loaded pipe racks.
• Fast-track turnaround project requiring construction work by contractors not familiar with the facility.  To minimize construction work, Anvil issued several stand-alone subcontract document packages to support pre-turnaround and tie-in efforts.
• Project required close coordination between Anvil and the field contractors.
• Anvil developed procurement information, including RFQ documents, bid tabulations, and expediting, inspection, and field receiving procedures.

Project to meet EPA Tier II regulations requiring a 30% reduction in overall gasoline sulfur content.  Project exceeded sulfur reduction goal by reusing existing major equipment in an idle Second Stage Diesel Hydrotreater Unit (DHT-2), and adding new or reconfiguirng major equipment, piping, structures, and electrical sub-station with associated infrastructure. 

Anvil provided full Engineering, Procurement, and Construction Support services within the clients phased project execution process, including:

• Develop project package
• Develop TIC Estimate for selected solution
• Determine field conditions
• Revamp - modifications
• New design
• RFI support
• Lessons Learned
• Check Estimate

Project Highlights

• Install 34 new pieces of equipment, including: 130-ft Stripper Tower, Reactor, Overhead Air Coolers
• Revamp equipment, including: Reactor, HP Separator, Compressor Auxiliaries
• Install new MCC building and Transformers
• Install 35,000 lf Pipe, 14,000 lf Piles, 110,000 lf Cable, 530 Instruments
• Develop 140 P&IDs and 1150 isometrics
