Across the globe, governments and communities are focused on reducing pollutants that have adverse environmental and health effects. Particulate, sulfur dioxide and nitrogen oxides are of specific concern. Carbon black production has been recognized as an industry that needs to address stack emissions by many countries, communities and operators. By the nature of the feedstocks used, which are derivatives of coal, natural gas and oil, sulfur dioxide (SO2) is present in the off gas. The formation of nitrogen oxides (NOx) is also expected in the reactor
based on process temperatures. To curb emissions of SOx and NOx, many carbon black producers have incorporated low sulfur fuels, low NOx burners and heat recovery into their process. However, there is a direct relationship between carbon black production plant size and exhaust gas volume. Thus, with recent industry consolidation and construction of larger plants, exhaust gas volumes have increased. With environmental regulations continually tightening, producers may need to consider new, more robust exhaust gas emissions control options to further drive down emissions.

Orlen Lietuva Contracts DuPont Clean Technologies for STRATCO® Alkylation Technolology
WILMINGTON, Del., DuPont Clean Technologies (DuPont) has been awarded the contract to supply ORLEN Lietuva (ORLEN) with licensing, engineering, and technical services for a STRATCO® alkylation unit and a MECS® spent acid regeneration (SAR) unit at the Mažeikiai refinery in Mažeikiai, Lithuania. The Mažeikiai refinery processes an average of 8 million tons of crude per year with capacity of up to 10 million tons of crude per year. In order to increase refinery complexity and flexibility of the Mažeikiai refinery, ORLEN commissioned DuPont for a STRATCO® alkylation unit with 240 kmta (6,000 bpsd) alkylate capacity. The alkylation unit will utilize LPG in the conversion to alkylate, and therefore upgrade refinery profitability. The 75 mtpd MECS® SAR unit, also under license from DuPont, will provide the refinery with a consistent supply of sulfuric acid, which is utilized as the catalyst for the alkylation unit, while ensuring compliance with the region’s stringent emission regulations.
