Zhejiang Petroleum & Chemical Co. Awards DuPont Contract for MECS® Sulfuric Acid Regeneration Unit

April 12, 2017 -
Zhejiang Petroleum and Chemical Co. (ZPC) in China has awarded and signed contracts for the engineering, technology license and proprietary equipment for a MECS® sulfuric acid regeneration (SAR) unit, licensed by DuPont Clean Technologies.  ZPC is constructing a greenfield refinery and petrochemical project on Dayushan Island, just off the coast of eastern China, near Shanghai and Ningbo. The USD 15 billion project is the largest privately led petrochemical and refining project in China’s history. The project will be executed in two phases with the first phase coming online in late 2018. After completion, the complex will have a refining capacity of 40 million tonnes/year, or 800,000 barrels per day.  The MECS® SAR unit for the ZPC petrochemical complex will have a capacity to regenerate 858 metric tons of spent sulfuric acid. The unit will produce a combination of products consisting of 98.3 wt% sulfuric acid, 99.2 wt% sulfuric acid, and 20% oleum. Furthermore, the MECS® SAR unit is designed to meet the Chinese Ministry of Environmental Protection’s current emission requirements for SO2, NOx and sulfuric acid mist. Jason Hartman, global market specialist for the MECS® SAR technology said, “China’s Ministry of Environmental Protection has enacted some of the most stringent point source emission requirements in the world. DuPont Clean Technologies is uniquely positioned to meet these new standards through enhancements to our MECS® SAR technology. These enhancements include the MECS® Vectorwall™ furnace, DynaWave® scrubbing and Brink® mist eliminators. When built, the SAR unit at ZPC’s petrochemical complex will achieve world-class environmental emissions, reliability and on-stream time.”
 

Peru to reevaluate environmental laws over La Oroya smelter

 

April 12, 2017 - Peru’s environment ministry has proposed modifying laws restricting sulfur dioxide emissions to attract buyers for a century-old poly-metallic smelter.  The Doe Run owned smelter and neighboring Cobriza copper mine priced together at $100 million have failed to find buyers at three auctions in a time of low commodity prices. Analysts say restrictive environmental regulations make the La Oroya assets unviable in an area cited as one of the most polluted in the world. The smelter requires upgrades costing over $700 million.  A new resolution proposes ten modifications including raising the sulfur dioxide limit from 20 to 250 micrograms per square foot, in line with regulations in Colombia, Chile and Mexico. The World Health Organization (WHO) guideline is 20 micrograms per cubic meter.  “The World Health Organization recommends the limit of 20 as a target value, as an ideal value, but it also establishes intermediate values. No country in the world has 20. This proposal is more in line with reality,” environment minister Marcos Alegre told Gestion.  Alegre added that the new standard will generate greater competitiveness in Peru’s economy and “also protects health.”  The La Oroya district in Peru’s highland Junin state, home to 1,600 La Oroya workers, will likely be abandoned if the smelter and mine operations fail. President Pedro Pablo Kuczynski has vowed to save the smelter while diversifying Peru’s mining sector from production to value-added services.  The request to ease environmental regulation comes from workers and potential investors suggesting that both are awaiting the regulation change while the government schedules more auctions before August. Current owner Doe Run went bankrupt after the 2008 global financial crisis.  The La Oroya district found infamy after TIME magazine ranked it on its list of “The World’s Most Polluted Places.” The health ministry revealed 99% of its children have over three times the safety level of lead in their blood. The toxic metal damages mental development and causes comas, convulsions and death.  According to a study by the WHO in Hong Kong where large-scale reductions in sulfur dioxide have been a success, decreasing child respiratory diseases and all-age mortalities.



DuPont to Supply MECS® Technology and Critical Equipment for Codelco's Two New Sulfuric Acid Plants

March 31, 2017 - MECS Inc., a wholly owned subsidiary of DuPont, has been selected to supply the sulfuric acid production technology for two new plants belonging to Corporación Nacional del Cobre de Chile (Codelco), the world's largest copper producer. The MECS technology will treat off-gas from the Chuquicamata Copper Smelter Complex in the Antofagasta region of northern Chile.  Longtime MECS partner, SNC-Lavalin, will provide detailed engineering, procurement and construction services for the new plants each of which is expected to produce 2048 t/d of market-grade sulfuric acid. These plants will replace existing facilities which have become environmentally obsolete.  "MECS technology for Chuquicamata will be designed and custom-built to address the site's specific needs, especially achieving world-class low emissions and high reliability," said Kirk Schall, executive vice president, MECS. "We are delighted that our best-in-class sulfuric acid production technology will help Codelco's Chuquicamata site realize its short- and long-term emissions targets while supporting the sustainable production of the Antofagasta region's most valuable resources. MECS looks forward to partnering with both Codelco and SNC through start-up and with Codelco throughout the life of the new facilities."  Construction of the two new plants will begin in 2017 and is expected to be completed the following year.

Teck Trail’s new acid plant; Construction slated to begin

March 23, 2017 - Structural element of the new $174 million acid plant at Teck Trail Operations are expected to start taking shape in a few weeks.  Three buildings from the 1960’s and ‘70s have been torn down to make way for the No. 2 acid plant, a carbon copy of the first emissions reducing plant Teck constructed in 2014.  “The project is progressing on schedule”, says Community Relations Leader Catherine Adair.  “We have completed demolition and the majority of excavation.  Foundation work is expected to begin in early April.”  HilTech Contracting and CIMS were awarded the contracts for demolition and site prep, the primary equipment supplier is the same company used for the previous build.  “The main equipment supplier for the project will be the same supplier as the No. 1 acid plant completed in July 2014”, Adair confirmed.  “as the new plant will be a replica of the previously constructed plant”.  Teck estimates approximately 650,000 hours of construction labour will be required to complete the build, which equates to about 160 jobs during construction.  “Contractor selection for foundation work, mechanical, structural and electrical work is currently underway”, Adair sadi.  “And other smaller contracts will be selected throughout the construction.  “The No. 2 acid plant is scheduled to become operational in the summer of 2019.  Over the last 20 years Teck has made significant investments to improve environmental performance at the Trail smelter, which is one of the largest zinc and lead smelting and refining operations in the world.  Notably, the company’s latest air quality summary to the Trail Health and Environment Committee showed that 2016 had the lowest annual average for lead and arsenic ever recorded in community air.  “The new acid plant represents an important investment in the ongoing sustainability and long-term future of Trail Operations”, Adair added.  “The new acid plant will significantly improve operating reliability and flexibility, reducing downtime and maintenance costs”.  SO2 (sulphur dioxide) emissions are projected to reduce a further five percent in addition to the 15 percent reduction in emissions realized from the 2014 installation of the No. 1 acid plant.  The acid plants are part of the process that converts sulphur from feed materials into useful products such as fertilizer.
