The new ethane storage terminal owned 50:50 by Brazilian-Mexican JV Braskem Idesa and the Netherlands-based Advario will be fully operational by mid-July, when the Etileno XXI cracker returns from a full-stop maintenance program, said Cleantho Leite, chief executive of Terminal Quimica Puerto Mexico (TQPM), in an interview with Argus. Edited highlights follow.
What does the new terminal represent for Braskem after years of limited ethane supply?
TQPM solves a long-standing ethane supply shortage in Mexico, which remains one of the largest ethane consumers in the region. Under the previous supply contract with Pemex, we did not have full supply. It was like having an F1 car with only 70pc of its fuel — eventually, we would run out of supply before even completing the race.
Now, thanks to this terminal, Braskem can import the ethane it needs from the US to ensure consistent operations. Of course, we will continue buying from Pemex whenever possible, as its ethane remains the most cost-effective solution. But with this infrastructure in place, we are no longer tied to a single supply source.
When will the terminal begin operating at full capacity?
We are currently in pre-operational stages, and commercial operations are expected to begin by late May. Then, the Braskem complex will enter its scheduled maintenance shutdown. Once it resumes in mid-July, we will begin transitioning to full utilization of the terminal.
The facility is fully capable of covering up to 100pc of Braskem's demand. In fact, it was designed with a 25pc buffer — excess capacity that could support future expansions. The equipment is ready, and whether we go from 75pc to 100pc in 15 days or in a month will depend entirely on Braskem's operating strategy.
What is going to happen with the ethane Pemex no longer uses?
For now, I do not see Pemex's own complexes significantly increasing their consumption of ethane. It is not like they will double their intake overnight. At least during 2025, Pemex is still in the process of reactivating its own crackers, so that volume will remain available to Braskem. If Pemex eventually requires more supply, it has its own import terminal. Alternatively, it could request capacity from TQPM if needed.
Also, Braskem has long-term contracts that allow flexibility in adjusting volumes. If there is unused ethane in a given month, we can resell it to other locations. That has always been part of our strategy. The Braskem group, through Braskem Trading and Shipping, has consistently found alternatives for any surplus.
Do you foresee any regulatory or permitting issues under the new legal framework in Mexico?
No. We already hold all relevant permits from the now-defunct energy regulator CRE, which are now under the authority of the new CNE. That means no additional permits are required for the terminal under the new framework.
Furthermore, the open-access guidelines established by the CRE are still valid and will be used by the CNE to issue and manage permits. The only other authorizations we need are from customs, which have not hindered pre-operations. Historically, the CRE reviewed transportation tariffs every five years, and we expect the CNE will follow the same regulatory schedule.
What is the outlook for Braskem's crackers in Brazil regarding a transition to ethane?
In Brazil, Braskem currently operates four crackers — three based on naphtha and one, in Rio de Janeiro, on ethane. The company is studying a broader shift toward ethane to reduce dependence on naphtha.
Shipments to Brazil would follow a similar model to what we are doing in Mexico, with contracts signed with US suppliers. Our Salvador Bahia plant already receives ethane occasionally, using vessels that take roughly 12 days to arrive. Mexico has a geographical advantage — just two days away from US ethane.
What are the long-term plans for TQPM?
Our immediate focus is stable operation and efficiency. Long term, the terminal is well located in the Interoceanic Corridor and could serve future industrial projects. We have space and docking infrastructure to add tanks for chemicals, ammonia or propane. Nothing is confirmed yet, but in 3–4 years we expect opportunities to emerge.
