The arrival of a special, 460-Mbbl shipment of U.S.-sourced naphtha in Venezuela a few days ago underscored a critically important fact, namely that production of Venezuelan heavy sour crude requires steady inflows of imported diluent. Today, we’ll discuss Venezuela’s need for diluent and how it’s likely to be met.
The push to decarbonize frequently focuses on the transportation sector, which is responsible for the largest share of global greenhouse gas (GHG) emissions. That has led to increased blending of ethanol into gasoline and the development of several alternative fuels, most notably renewable diesel (RD) and sustainable aviation fuel (SAF). But as production of those two fuels accelerates, an often-overlooked byproduct of their creation is beginning to attract more attention: renewable naphtha. In today’s RBN blog, we explain the similarities and differences between traditional naphtha and renewable naphtha, look at how renewable naphtha is produced, and show how it can be used to help refiners, petrochemical companies and hydrogen producers meet their sustainability goals and reduce the carbon intensity (CI) of their products.
As the world economy tries to dust itself off after COVID, increased demand for transportation fuels coupled with tight supplies has become a pain. The shortage escalated to crisis levels this spring and summer when, in response to Russia’s invasion of Ukraine, sanctions eliminated Russian exports of crude oil and intermediate feedstocks to the U.S. and severely reduced flows to Europe. While Russia has been able to find some alternate markets, its overall product exports are down significantly. Adding to these product-supply reductions are policy decisions by Putin’s allies in China to reduce their product exports to a trickle. Chinese exports had been an important part of regional supply in recent years, but authorities there have decided to decrease the number and size of export quotas issued, leaving many refineries in China operating at rates well below their capabilities. In today’s RBN blog, we take a closer look at how developments in Russia and China have played a major role in the current global shortage of refined products.
It’s been over a month since the Deep Freeze swept across Texas, shutting down the power grid, curtailing natural gas supplies, and generally wreaking havoc on the state’s population and infrastructure. The petrochemical industry was hit particularly hard, with every ethylene-producing steam cracker in the state and many in nearby Louisiana forced into hard shutdowns — that is, production coming to a screeching halt with little or no preparation. The result was unit damage well beyond what typically happens with other weather-related events like hurricanes, where there is usually some ability to manage an orderly shutdown. Consequently, at least half of the industry’s capacity to produce ethylene and its by-products remains offline, a development that is ricocheting through supply chains across the economy. Today, we examine the magnitude of the damage, consider what is happening in ethylene markets — the epicenter of the turmoil — and contemplate the longer-term implications of the outages.
The COVID-19-induced social isolation and subsequent economic slowdown have caused major drops in U.S. refined products consumption, especially gasoline and jet fuel, which have experienced declines of as much as 44% and 70%, respectively, relative to similar periods in 2019. Diesel fuel consumption has been off as much as 20% on the same basis, and given that COVID is a global crisis, product exports have also fallen. As a result, U.S. refinery utilization has dropped to less than 70% for the last few weeks, the lowest levels since September 2008 during Hurricane Ike. All this presents refiners with two challenges: (1) reduced total demand; and (2) the disproportionate decline in gasoline and jet fuel. Each refinery is configured differently and has a varying degree of flexibility to react to these challenges. Today, we discuss what refiners can do to adjust operations and product yields, and examine the point at which some refineries might be forced to shut down completely.
Sharply declining refinery demand for crude oil was a key driver in the historic collapse in near-term futures prices for WTI at Cushing earlier this week. With stay-at-home directives in place in most of the industrialized world, U.S. — and global — demand for motor gasoline and jet fuel has plummeted to levels not seen in decades. These changes in refined-products demand, which may continue for months, already are having significant impacts on U.S. refineries — not just in how much crude oil they need but in operators’ decisions on whether to adjust their crude slates and ramp down or alter their operations. Their urgent challenge is to revise their yields to something close to the appropriate volumes of gasoline, diesel and jet fuel. Today, we begin a blog series on the U.S. refining sector and what refiners can — and can’t — do to adapt to these extraordinary times.
Every day, about 1.8 million barrels of NGLs, naphtha and other ethylene plant feedstocks are “cracked” to make both ethylene and an array of petrochemical byproducts. And every day, decisions are made for each steam cracker on which feedstock—or mix of them—would provide the plant’s owner with the highest margins. Within each petchem company, these decisions are optimized by staffs of analysts and technicians using sophisticated and complex mathematical models that consider every nuance of a specific ethylene plants’ physical capabilities. Fortunately for us mere mortals, it is possible to approximate these complex feedstock selection calculations for a “typical” flexible cracker using a relatively simple spreadsheet model. Today we continue our series on how the raw materials for ethylene plants are picked with an overview of RBN’s feedstock selection model, a review of feedstock margin trends, and an explanation of how the model also can be used to indicate future NGL and naphtha prices and to assess the prospects for various industry players.
The normal butane market was anything but normal the past few weeks. All’s back to square one now, but in the last week of 2016 the price for normal butane spiked to more than $1.20/gal from only $0.73/gal in November. The differential between isobutane and normal butane plummeted into record-shattering negative territory. And the margin from cracking normal butane to make ethylene and other products fell off the chart—literally, our PowerPoints had to be reworked to show how much the margin had fallen. What the heck went on there? Today, we discuss the recent upheaval, what may have caused it, and why things snapped back to normal so quickly.
The Shale Revolution has had a profound impact on U.S. NGL markets by vastly increasing production and by lowering NGL prices relative to the prices of crude oil and natural gas. That has been good news for the nation’s steam crackers, the petrochemical plants that have enjoyed low NGL feedstock prices since 2012. But NGL markets are in for some big changes as new U.S. steam crackers coming online over the next two years will be competing for supply with export markets, raising the specter of higher NGL prices—a good thing for NGL producers, but not so for petrochemical companies. How this plays out will be determined by the feedstock supply decisions petrochemical producers make as NGL prices respond to rapidly increasing demand. Today we begin a series on how steam cracker operators determine day-by-day which feedstocks are the most economic, and on the factors driving the value of ethylene feedstock prices.
The prospects for an ever-expanding boom in propane exports from the U.S. Gulf Coast are dimming, even as export volumes stand at near-record levels and as new export capacity continues to come online. Why? It comes down to supply and demand. With oil and NGL prices at today’s levels, propane production is leveling off, not rising, and U.S. Gulf Coast domestic demand for propane will be increasing—from new propane dehydrogenation (PDH) plants and propane’s use in ethylene steam crackers—at the same time that export volumes out of the East Coast are quadrupling. In today’s blog we consider the possibility that what goes up must come down.
