Sulfex Technology Commercialization - Pyramid E&C - Hydrocarbon Technology Solutions

Pyramid E&C Selected To Commercialize The Sulfex™ Technology

Pyramid E&C LLC is pleased to announce that it has been chosen by Alternative Environmental Technologies (www.alt-enviro-tech.com) to build and install the first commercial SulfexTM plant in the US. AET has partnered with one of the largest energy companies in North America to operate the facility.

SulfexTM, developed by AET, is designed to reduce sulfur content in sour hydrocarbons to meet ultra-low sulfur specifications. The process also overcomes several shortcomings of conventional hydrodesulfurization (HDS or hydrotreating) technology. These include:

Severe operating conditions, such as high temperatures (~800°F) and pressures (~3500 psig)
Potential for a runaway reaction
High capital and operating expenditures
A hazardous hydrogen environment
Toxic hydrogen sulfide production
Massive carbon dioxide emissions

SulfexTM, the most advanced form of oxidative desulfurization (oxytreating), has the following competitive and environmental advantages over HDS:

Moderate operating conditions at atmospheric pressure, with a maximum operating temperature of 212ºF.
Economical: about one tenth of the CAPEX and lower OPEX compared to HDS
Safety: less inflammable reagents and inert liquid byproducts
Negligible environmental impact
Smaller, modular, and/or mobile installation options

The plant will process 5,000 barrels of diesel per day, starting from an initial capacity of 1,000 barrels per day. AET has previously operated two pilot plants at its Reno, NV facility and one in the Asia Pacific region to validate the technology. The SulfexTM process has also been independently verified by the U.S. Department of Energy’s Argonne National Laboratory.

Pyramid E&C has been providing full EPC scope worldwide for conventional and renewable hydrocarbon facilities for more than 25 years, with a spotless track record of delivering more than 700 projects fully meet Safety, Quality and Performance expectations. The company’s plants and processes are defined by full modularization, decarbonization and digitalization to support stakeholder goals in Mobility, Operational Simplicity and ESG initiatives.

“We are honored and excited to partner with Pyramid E&C to continue our eco-friendly, sustainable business mission and introduce cutting edge technologies to the hydrocarbon fuels industry.”
