MOSCOW (MRC) -- Enterprise Products Partners (EPP; Houston, Texas) has started operations at its 425,000-metric tons/year isobutane dehydrogenation plant at Mont Belvieu, Texas, said Chemweek.
Volumes are expected to continue ramping up over the next two weeks at the facility, which is supported by long-term, fee-based contracts with customers, says EPP. The plant will ultimately be able to process approximately 25,000 b/d of butane into 425,000 metric tons/year of isobutylene.
The isobutylene produced by the plant will provide the necessary feedstock to fully utilize the capacity of EPP’s methyl tert-butyl ether (MTBE) and high-purity isobutylene assets and meet growing market demand, says the company. US supplies of isobutylene have decreased as a result of the increased use by steam crackers of lighter feedstocks, specifically ethane, instead of crude oil derivatives, it says.
The completion of the new facility “extends our butane value chain by allowing us to increase production of both high-purity and low-purity isobutylene to be used primarily as feedstock to manufacture lubricants, rubber products, and fuel additives,” says CEO Jim Teague. The project was completed on time and under budget, he says.
EPP’s second propane dehydrogenation plant, currently under construction at the same site, is on schedule for completion in the first half of 2023, he adds.
The isobutane dehydrogenation plant, which is using Honeywell’s Oleflex technology, was built by construction contractor Optimized Process Designs. The project was announced by EPP in January 2017.
Ethylene and propylene are feedstocks for producing polyethylene (PE) and PP.
According to MRC's ScanPlast report, Russia's estimated PE consumption totalled 1,589,580 tonnes in the first nine months of 2019, up by 7% year on year. Shipments of all PE grades increased. The estimated PP consumption in the Russian market was 976,790 tonnes in January-September 2019, up by 4% year on year. Shipments of PP block copolymer and homopolymer PP increased.
