One confounding factor in this research is that the reactivity to hydrodesulfurization of organosulfur compounds in liquid fossil fuels varies widely.
The new product, Ketjenfine(R) 770 hydrodesulfurization catalyst, built on patented STARS(TM) technology, will enable ultra-low-sulfur diesel (ULSD) refiners to improve their operating margins substantially by increasing catalyst cycle length; increasing throughput; or running cheaper, lower quality feed stocks, all without additional, new capital expenditure.
In the presence of a catalyst, reactors are for hydrodesulfurization, denitrogenation and removal of oxygenated compounds and in each weighs nearly 550 tons and is 30 meters long.
As anticipated, segment results were negatively impacted by approximately $30 million due to catalyst changes at two critical hydrodesulfurization (HDS) units.
Fluor previously built a naphtha hydrodesulfurization unit for Galp Energia in 2002.
On October 28, Monday, Achinsk refinery received the first hydrocracking reactor which is built for vacuum CGO oil hydrocracking and hydrodesulfurization reactions.
Compared to the conventional hydrodesulfurization process (HDS), the capital cost of the ultrasound plant and equipment is extremely low, with a rapid return on investment," Gunnerman said.
Foster Wheeler will also upgrade the existing mild hydrocracking and gasoil hydrodesulfurization units, steam and electrical systems.
Terry Henderson said, "I believe that CrystaSulf presents a unique advantage to the oil refiners in treating hydrogen recycle gas in hydrodesulfurization units with the added benefit of improving recycle gas purity, which aids in cost-effectively increasing sulfur removal capacity and catalyst life.
YOKOHAMA, Japan -- Chiyoda Corporation (TOKYO:6366; ISIN: JP3528600004), Japan's leading engineering and construction firm, today announces that it is licensing titania catalyst for ultra deep hydrodesulfurization (HDS) of diesel oil to Axens, a French subsidiary of IFP.
