Jeanblanc International Inc. has a proprietary desulfurization process that reduces sulfur in crude and refined products to new global limits with NO heat or pressure. Additionally, Jeanblanc International, through its partner, offers a new revolutionary Refinery Conversion Technology. The Modular Conversion System produces products of a complex refinery at a fraction of the cost with quick installation and commissioning.

Sulfur is an undesirable component in fuels because it releases sulfur oxides into the atmosphere causing acid rain, creates corrosive combustion by-products, and increases deposits on fuel injection and combustion systems. Because of these environmental problems sulfur is strictly regulated in most industrialized nations and the sulfur content greatly affects both the price of crude oil and refined products.

Recent regulations in the US limit sulfur in highway diesel fuel to 15 ppm, down from 500 ppm previously. The size of the problem can best be shown by the hundreds of millions of dollars being spent to implement large scale sulfur hydro-treating systems. Refineries, especially smaller refineries, are closing do to the costs to build or retrofit their existing facilities to meet these new limits. Jeanblanc Desulfurization does not require those high expenditures.

Jeanblanc International, Inc. discovered a new molecular science which has not yet been discovered by others. Through more than 10 years of R&D, JBI developed it into a "no added heat or pressure" sulfur removal process that can reach the internal sulfur atoms within hydrocarbon molecules in order to meet the new industry standard limits. The Jeanblanc Desulfurization Process (JDPSM) removes sulfur from crude oil as a pre-treatment process or post refining treatment of any refined product.

To meet new sulfur limits Hydro-desulfurization (HDS), the present industry standard method of removing sulfur {2}, needed to increase the heat and pressure by nearly double resulting in huge costs to purchase new equipment. Hydro-desulfurization {2}, now requires high pressure up to 1200 psi and high temperatures up to 450-649 C or 1,200 F. degrees to meet these new limits. These costs have caused many refineries to close due to huge equipment cost and on-going energy costs. Desulfurization costs are the reason "highway" diesel costs increased from $0.20 below gasoline in 2006 to exceeding gasoline by $0.40-$0.60 per gallon at the pump for consumers in today's prices. JDPSM does not require any added pressure or heat, saving both those huge equipment and huge on-going energy costs.



Jeanblanc Desulfurization Process
  • No added heat
  • No added pressure
  • 1/3 of HDS cost
  • Low pressure vessels
  • Low cost equipment and ongoing costs


  • High temperature 1,200 F
  • High pressure, 1,200 psi
  • Hundreds of millions to retrofit refineries
  • High Pressure vessels
  • High cost of facilities and ongoing costs

Higher the sulfur, higher the pressure and temperature needed, higher
the cost of the vessel and energy.

To reach new limits for diesel fuel, current hydro-treating technology is difficult to reduce the sulfur content to less than 50 ppm because the remaining sulfur compounds in current diesel fuel are the refractory sulfur compounds. These refractory sulfur compounds are one or two alkyl groups, which strongly inhibit hydro-desulfurization. These are the "internal sulfur atoms" in the hydrocarbon molecules that must at least partially be removed which greatly increases the cost of hydro-desulfurization. Studies have shown that in order to reduce the sulfur content of diesel fuel from 500 ppm to less than 50 ppm using current hydro-treating technology, even with catalysts twice as active as current commercial catalysts, the reactor volume must be at least twice the size of those currently used in refineries with 500 ppm hydro-desulfurization capability.

As the industry knows, the more important problem along with the increase in volume is the required higher-temperature and higher pressure within the reactor. This is very expensive! The increase of catalyst activity by even 50 % over existing hydro-treating catalysts is very hard. Over the past 50 years existing hydro-treating catalysts have been developed and optimized so improvements are often small and only incremental without major increased size, temperature and pressure to improve abilities of existing catalysts. Instead, JDPSM uses a revolutionary chemical reaction method with oxygen based reactions with much different catalysts and proprietary additional energy rather than standard hydrogen based reactions and standard catalysts and high heat used in hydro-desulfurization.

JDPSM is proven to remove 90%+ sulfur from heavy crude oil such as Mayan, over 98%+ from diesel and over 87%+ from resid without added heat or pressure. This creates tremendous cost savings not only in equipment but also ongoing energy costs.

JBI has spent $ millions in R&D, engineering, pilots and reports to verify and document that JDPSM reduces sulfur without high pressure or heat at a fraction of a cost of the present hydrogen technologies.

The significant cost savings of JDPSM is based on a system that requires "NO added heat or pressure" AND with designs to utilize mostly standard industry equipment. As those familiar with refining operations know, energy costs associated with the required heat and pressure of refining operations is one of the largest operating costs of a refinery!

JDPSM "is very progressive and unmatched or unequaled, to our awareness at the Research Triangle Institute, by any other desulfurization"… states Dr. Santosh Gangwal, Program Director, Fuel Technology-Engineering & Environmental Technology at Research Triangle Institute as he described an earlier generation of JDPSM. He was the team leader in charge of taking 1st generation JDPSM from bench to full-scale, an expert with normal hydro treating methods comparing JDPSM. Through continued development, JDPSM is now in its 3rd generation and is even more efficient and effective than earlier versions described by Dr. Gangwal.

Chris Marshall and other scientists of Argonne National Laboratory developed catalysts to try and work at lower temperatures stating: "One of the amazing aspects of the MSC materials is that they are hydrothermally stable (steam stable) at temperatures up to 450°C. This indicates that there is some strong bonding going on between the clay particles that cannot be destroyed by steam. Many catalyst supports fail this test. " He also states that lower - pressure, lower-temperature diesel desulfurization seems likely to become something of a "holy grail" for refiners, since the average HDS unit in the U.S. achieves only 600 psig –well below the 1,000 psig or even higher pressures… required for deep desulfurization of certain diesel streams." {2}

The Jeanblanc Desulfurization Process (JDPSM) is that "Holy Grail" which removes sulfur from heavy crude oils as well as heavy refined products such as #6 or residual fuel or refined lighter products. JDPSM is a new sulfur-removal system that saves money and reduces pollution from acid rain caused by sulfur in fuels when burned.

Higher the sulfur, higher the pressure and temperature needed, higher the cost of the vessel and energy.

Summary: Higher sulfur means higher pressure and heat, "At higher pressure the unit becomes more expensive". Jeanblanc Desulfurization Process is a new technology that does not need high heat or pressure. Additionally, JBI’s Conversion System for refining of crude oil will also revolutionize the oil industry. For more information on either technology, contact Jeanblanc International Inc.
