MOSCOW (MRC) -- Petroleos Mexicanos (Pemex; Mexico City) is advancing a refinery rehabilitation program that will enable it to process 1.2 million b/d of crude oil by the end of 2020 and evaluating a reconfiguration of its petrochemical facility at Cangrejera, Mexico, into what would be its eighth refinery, said Chemweek.
The state-owned company will conclude viability studies in the coming weeks for the building of a 200,000-b/d crude processing train at Cangrejera, Pemex CEO Octavio Romero Oropeza said during a webcast at the weekend. Pemex is close to defining construction times, costs, and profitability, as well the availability of light crude oil over the lifetime of the project, Romero said.
Reconfiguring Cangrejera is an idea that has been explored for decades, with the potential project discarded by Pemex in 2008 and brought out again by trading group Vitol in 2016 under a joint venture. Vitol proposed the project, but Pemex wasn't interested at the time, according to local media.
Cangrejera currently has a 12,000-b/d crude processing unit to produce naphtha as a petrochemical feedstock and other components, for the production of gasoline at Pemex’s 285,000-b/d Minatitlan refinery, said Romero. Pemex currently imports 25,000 b/d of naphtha to operate Cangrejera, he added.
Mexican president Andres Manuel Lopez Obrador said that the reconfiguration was an attractive brownfield project, with multiple advantages such as a low environmental impact and the ability to use existing infrastructure. If the decision is taken to reconfigure Cangrejera, Pemex must complete the work no later than 2023, the year the current presidential term ends, Lopez Obrador said. This would ensure the project is completed and not abandoned by future administrations, he added.
Crude oil availability will be a challenge for this project amid the reluctance from Mexico to import light crude oil. The government expects to refine 1.6 million b/d of crude oil by 2022. Pemex has a goal of producing 2.4 million b/d of crude oil by 2024. However, IHS Markit forecasts Mexico’s crude output will be 1.5 million b/d by that year.
Mexico’s energy secretary, Rocio Nahle, said that Mexico expects to process 1.2 million b/d of crude oil by the end of 2020, a level last reached during a handful of months in 2014, according to Pemex data. The country is moving to boost its crude processing levels despite having negative refining margins in the last two quarters: minus USD2.64/bbl in the fourth quarter of 2019 and minus USD12.51/bbl during the first quarter of 2020.
Pemex CEO Romero said works are also moving ahead for the rehabilitation of the Minatitlan refinery, which will allow the facility to reach a reliable processing level of 170,000 b/d by the end of the year, a significant recovery from 26,000 b/d processed in 2018 and 96,000 b/d in 2019. Minatitlan only operated for five months in 2018 and four months in 2018.
Pemex currently has two ethane-based steam crackers, at Cangrejera and Morelos. Mexico has been a net importer of ethane since 2018, with its domestic ethane production for 2020 put at around 77,000 b/d, according to a recent IHS Markit North American Light Olefins monthly report. A total of approximately 67,000 b/d is required to feed its own two crackers, while Pemex must also fulfil its long-term contract requirements to Braskem-Idesa of 66,000 b/d.
Ethylene and propylene are feedstocks for producing PE and PP.
According to MRC's ScanPlast report, Russia's estimated PE consumption totalled 383,760 tonnes in the first two month of 2020, up by 14% year on year. High density polyethylene (HDPE) and linear low density polyethylene (LLDPE) shipments increased due to the increased capacity utilisation at ZapSibNeftekhim. At the same time, PP shipments to the Russian market were 192,760 tonnes in January-February 2020, down by 6% year on year. Homopolymer PP accounted for the main decrease in imports.
