WICHITA, Kan. –INVISTA Performance Technologies (IPT) and Koch-Glitsch, affiliates of Koch Industries Inc., announced today an expansion of their partnership to offer the proprietary ExoS™ technology to customers. The technology allows refineries to generate an olefin rich C6/C7 raffinate with less than 10 ppm sulfur that bypasses the FCC naphtha hydrotreater for direct blending.

Wichita, Kansas —INVISTA Performance Technologies (IPT) and Koch-Glitsch, subsidiaries of Koch Industries Inc.announced today that they are expanding their partnership to license their proprietary ExoS™ technology to customers. Refineries can use this technology to produce FCC gasoline rich in C5-C7 olefins with sulfur content below 10 ppm, which can be blended directly without hydrotreating.

With eight units in commercial operation and seven units in the design and construction phase, the technology is commercially proven to deliver value by preserving octane and reducing hydrotreater size, operating expenditures, and capital expenditures when installed with a new hydrotreater. As a revamp, the technology preserves octane number, lowers operating expenditures, and frees up hydrotreater capacity and hydrogen availability.

Currently, this technology has been proven by 8sets of operating industrial units and 7 sets of industrial units in the design/construction phase. When constructed with a new hydrotreater, using ExoS^TMtechnology can reduce the size of the hydrotreater unit, and while protecting octane value, reduce operating costs and investment costs; when revamping a hydrotreater, this technology can protect octane value, reduce operating costs, and free up hydrotreater capacity and hydrogen availability.

The ExoS™ process technology – developed and commercialized by China Petroleum University-Beijing (CUPB) and Hebei Refining Technologies (HRT) – utilizes a proprietary solvent to extract sulfur and aromatics from mid-cut FCC naphtha (C6/C7). The sulfur-rich extract is sent to the FCC hydrotreater for sulfur removal while the olefin rich raffinate with less than 10 ppm sulfur is sent directly to the blending pool. This reduces the hydraulic load on the hydrotreater and avoids the saturation of the high-octane number olefins. Alternatively, this low-sulfur, olefin-rich, mid-cut FCC naphtha can also be utilized as feed for other processes to further increase its value.

“Refineries worldwide are facing the challenge of ever decreasing total sulfur limits in the gasoline pool,” said Christoph Ender, Koch-Glitsch senior vice president of global sales and business development. “Expanding our partnership with INVISTA Performance Technologies to offer ExoS will provide our customers with a valuable solution that is easier to operate, lower in cost, and more environmentally friendly to stay ahead of the sulfur curve versus hydrotreating alone.”

“Globalrefineriesare facingthechallenge of increasingly stringent gasoline pool sulfur content limits.”.”Koch-Glitsch's vice president of sales and business development, Christoph Ender, said, "Compared with the technology of using only a hydrotreater, ExoS™ is a more forward-looking technological option for tackling sulfur challenges, offering simpler operation, lower costs, and greater environmental friendliness."

Approximately 40 wt% of the olefins in full range naphtha are in the mid-cut (C6/C7) and approximately 90 wt% of the sulfur species are thiophenic. The ExoS™ solvent is formulated to extract the thiophenic sulfur from the mid-cut naphtha for further processing in the hydrotreater. The process utilizes a series of extraction and distillation columns optimized to recover more than 90% of the olefins in the raffinate and more than 95% of the sulfur in the extract.

“We are excited to add the ExoS technology to our expanding refinery portfolio,” said Mike Massa, INVISTA Performance Technology Licensing Director. “The refining industry no longer has to accept significant octane loss to meet mandatory sulfur limits. The ExoS process provides an option to preserve octane, and optimize the hydrotreater design and operation.”
