Design, engineering, procurement, fabrication, construction, and testing service of three (3) large Tanks at the LNG liquefaction facility and export terminal in Kitimat, BC. Field Erected Tanks include one Condensate Storage Tank (105’ diameter x 60’ height), one HTF Storage Tank (36’diameter x 60’ height), and one Treated Raw Water Holding Tank (100’x 60’ height.) Prefabrication requirements for Manway, Nozzle, and Internal piping self-performed by our fabrication facility. Performed two steel dome roof air raises on the two largest tanks in our scope. Full external coating (all tanks), full internal coating (one tank), and exterior insulation (two tanks).

The scope consisted of erecting 4 world-scale fired heaters including 4 x twin cell radiant sections with shared convection sections and stacks, 120 burners to produce a duty of close to 400 MMBtu, modularization of the radiant boxes, installation of radiant coils on each cell, 25 levels of platforms, and ~2,100 LM of fuel gas supply lines. Critical lift plans with the use of 650- ton cranes and aerial
work platforms.

Commissioning three biogas preprocessing facilities - one at each farm site - a Central Processing Facility, the interconnecting pipeline, and the product line to the pipeline owner’s metering skid.

Primoris is executing the detailed engineering for CO2 capture at up to 24 Ethanol processing plants throughout the Midwest. Upon capture of the CO2, the CO2 will be transported via pipeline to North Dakota where it will be permanently and safely stored underground in deep geological storage locations. This project will have the capacity to capture and permanently store up to 12 million tons of CO2 every year.

Primoris was retained to design and build a completely new natural gas liquefaction and distribution facility in Boron, California. Primoris was responsible for the engineering, design, supply of equipment/materials, and union construction of a 240,000 GPD natural gas liquefaction and distribution facility, designed to expand production as demand increases. The LNG production plant was the largest in the Southwest and the first large-scale plant in California.

Primoris Engineering performed unit modifications on the Coker Unit which increased unit throughput to 19,000 BPSD. The scope of work included process design, detailed engineering, and procurement services for new/replacement equipment, vessel repairs, new foundations, pipe fabrication, miscellaneous pipe supports, structural steel fabrication, new / replacement instrumentation, a new heater radiant section and air preheater. The project also included a new steam generator, pumps, and tower internals.

This Biogas to Liquids Plant is a new 30 BPD renewable diesel facility. Primoris Design & Construction was awarded engineering, procurement, and fabrication services. The facility converts methane from dairy farm digesters into renewable diesel fuel and stabilized naphtha. The project includes Syngas Unit, GTL Section, and Fractionation Section. This process significantly reduces the impact to the environment by increasing the sustainability of the dairy farm and producing high-quality transportation fuels with zero sulfur emissions. In addition to dairy farms, these units can be installed at any biogas source, including swine farms, poultry farms, landfills, food waste facilities and wastewater facilities.

The facility is a new 30,000 BPD renewable diesel unit that converts animal fats, used cooking oil and inedible corn oil into renewable diesel fuel. Primoris Design & Construction performed OSBL EPC services including fat, naphtha, and green diesel storage tank facilities, reverse osmosis unit, amine regeneration unit, pumping facilities at the pipeline interfaces, new piping, electrical, and instrumentation.

Primoris Design & Construction performed FEL 2 and FEL 3 engineering for a new Slurry Filtration Project. The scope of work included process design, detailed engineering, and FEL estimating services for a new modular processing facility including integration of the filtration process into the existing refinery process.

Primoris Design & Construction performed FEL 2, FEL 3, Detailed Engineering, Procurement, and Field Support for the 16,500 BPD GDU project. The purpose of this FCC GDU is to reduce the sulfur content to 10 ppm, while minimizing octane loss, of three different composition FCC gasoline feed streams and a straight run naphtha feed by utilizing Axens’ Prime G+ Technology. The process uses a selective catalyst in a Selective Hydrogenation Unit (SHU) Reactor maintaining octane which then passes through the Hydrodesulfurization Reactor (HDS Reactor) where sulfur is removed while olefin saturation is kept to a minimum in order to retain octane. Following distillation and further desulfurization, the products are then used directly as a gasoline blending stock.
