Scientists develop a way to predict corrosion from crude oil





Using X-ray techniques, scientists at the SLAC National Accelerator Laboratory are developing an analysis tool that can more accurately predict how sulphur compounds in a batch of crude oil might corrode equipment– an important safety issue for the oil industry.
The results of these ongoing experiments at the Stanford Synchrotron Radiation Lightsource (SSRL) at the Department of Energy’s SLAC National Accelerator Laboratory will improve industry guidelines. The goal is to characterize the types of sulphur that are most critical to identify in the oil, in order to better anticipate the potential for corrosion rates.
A team of researchers from Chevron Corporation and the University of Saskatchewan are performing a series of studies at SSRL to closely examine forms of sulphur in crude oil.
“By looking at crude oil with a combination of X-ray spectroscopy techniques, we were able to examine and describe the complex chemistry of the sulphur compounds with high specificity,” said Monica Barney, a materials research engineer at Chevron.
Difficulties in the data
Nearly a million barrels of oil are processed on a given day at Chevron’s major refineries throughout the US, and the sulphur present in the oil can react with the metals in various types of equipment and cause damage. These reactions are something engineers must consider to ensure safe and reliable processing.
But high sulphur concentrations don’t always correlate with high levels of corrosion, or the other way around, and this makes it difficult to anticipate how corrosive a particular crude oil will be.
“We can measure the concentration of sulphur, but it doesn’t tell you about the reactivity,” says Barney, who is leading the studies. “Knowing the type of sulphur in crude oil is critically important for predicting properties related to corrosion.”
The collaboration began when Barney was working on a separate corrosion study at SSRL. After collecting the data, the Chevron team was struggling with how to interpret the complexities they saw in the results.
In an online search, they came across a diagram developed by two professors at the University of Saskatchewan, Graham George and Ingrid Pickering, while they were on the staff at SSRL. They have conducted molecular biology and toxicology experiments at the SSRL synchrotron for years.
The diagram showed spectroscopy information gathered from the superimposition of data on many sulphur types, similar to what’s seen in crude oil. It showed how comparing an overall spectrum to a library of standards could identify individual types of compounds.

The Appointments Committee of the Cabinet under the Government of India has approved his appointment to the post of CMD, till the date of his retirement, an order issued by Department of Personnel and Training (DoPT) said. Shanker, 56, will have a nearly four-year term until March 2021.

Making concrete from wood




Researchers from the National Research Programme "Resource Wood" have developed a type of concrete that largely consists of wood. The building material offers the construction industry new possibilities and is based in large part on renewable resources.
Houses can be made of wood, as they were in the past – or of concrete, as they are today. To build for tomorrow, the two building methods are being combined: these hybrid structures, which contain both wood and concrete elements, are becoming increasingly popular in contemporary architecture.
In the context of the National Resource Programme "Resource Wood" (NRP 66), Swiss researchers have now developed an even more radical approach to combining wood and concrete: they are fabricating a load-bearing concrete which itself consists largely of wood. In many blends, the volume fraction of the wood is over 50 percent.
Cement-bonded wood products have been around for more than a hundred years. Yet previously they were used only for non-load-bearing purposes, such as insulation. Daia Zwicky, head of the institute for building and environmental technologies at the school of engineering and architecture of Fribourg, wondered whether it wasn't time for a more ambitious use of wood-based concrete.
Floating concrete
Together with his team, Zwicky experimented with the content and granularity of the wood as well as diverse additives and subsequently subjected the various blends to rigorous tests. The main difference from classical concrete is that the gravel and sand content is replaced with finely ground wood. In other words, sawdust rather than small stones is mixed in with the cement. Thanks to the high wood content, the new building materials show good flame retardance and act as thermal insulation.
"They weigh at most half of what normal concrete weighs – the lightest of them even float!" said Zwicky. Moreover, as the materials are based largely on renewable resources, after dismantling they can be reused as a source of heat and electricity. The wood content can be burnt in waste incineration, although for everyday use it conforms to fire protection standards.

Eastman licenses bio-based FDCA technology to Origin Materials




Eastman Chemical Company have entered into a non-exclusive license agreement with Origin Materials (formerly known as Micromidas), to license its proprietary 2,5-furandicarboxylic acid (FDCA) and FDCA derivatives production technology from renewable resources.
Origin also recently purchased an oxidation pilot plant from Eastman that will enable Origin to demonstrate the licensed technology.
FDCA has been identified by US Department of Energy as one of the top 12 bio-based building blocks and can be converted into a number of high-value chemicals or materials. FDCA can be used to produce polymer resins, films, and fibres and as a building block for plasticizers. The largest initial FDCA applications are expected to be to make 100 percent bio-based plastics, such as polyethylene furanoate (PEF) for beverage containers and food packaging.
Eastman has developed key technologies for economically competitive conversion of 5-(hydroxymethyl) furfural (5-HMF) and its derivatives to crude FDCA, polymer grade FDCA and polymer grade dimethylfuran-2,5-dicarboxylate (DMF). Eastman’s technology is broadly flexible in terms of feedstocks and provides efficient production of crude FDCA, polymer grade FDCA and polymer grade DMF.
“Eastman’s technology provides robust and multiple integrated engineering options for commercialization. This agreement leverages the world-class FDCA production technologies we have developed over the last several years.” Eastman is actively pursuing a broad intellectual property strategy with dozens of US and foreign patents awarded or pending,” said Eastman’s Damon Warmack, senior VP of corporate development and chemical intermediates.

Westlake Chemical acquires additional 5 pc stake in OpCo




Westlake Chemical Partners LP (WLKP) has agreed to acquire an additional 5 percent interest in Westlake Chemical OpCo LP (OpCo) for approximately $229.2 million.
This transaction will increase the Westlake’s limited partner interest in OpCo from approximately 13.3 percent to approximately 18.3 percent and will represent the second purchase of additional interests in OpCo by Westlake since its initial public offering.
OpCo’s assets are comprised of three ethylene production facilities, which primarily convert ethane into ethylene and have an aggregate annual capacity of approximately 3.7 billion pounds and a 200-mile ethylene pipeline.
OpCo sells approximately 95 percent of its ethylene production to Westlake Chemical Corporation under a long-term supply agreement, which provides for a stable $0.10 margin per pound.
“The acquisition of this additional interest in OpCo, which provides a high-quality, stable, fee-based earnings stream, represents just one of a number of levers we can use to grow our distributions over time. In addition to purchasing increased interests in OpCo, the partnership can pursue organic growth opportunities such as capacity expansions in OpCo’s ethylene production facilities and acquisitions of other qualified assets from third parties,” said Albert Chao, president and chief executive officer, Westlake Chemical Partners LP.

New additive enhances CO2 conversion to multicarbon fuels




Chemists have figured out a new, more efficient way to create carbon-based fuels from carbon dioxide (CO2). In chemical reactions performed in the lab, a Caltech team has identified a new additive that helps selectively convert CO2 into fuels containing multiple carbon atoms-a step toward ultimately making renewable liquid fuels that are not derived from coal or oil.
"The results were quite shocking," said Jonas Peters, Bren professor of chemistry at Caltech and director of the Resnick Sustainability Institute, who jointly led the research in collaboration with Theodor Agapie, professor of chemistry at Caltech. "Usually, in these types of reactions with CO2, you see a lot of by-products like methane and hydrogen. In this case, the reaction was highly selective for the more desirable fuels that contain multiple carbons—such as ethylene, ethanol, and propanol. We saw an 80 percent conversion to these multi-carbon fuel products, with only 20 percent or so going into hydrogen and methane."
Fuels with multiple carbon atoms are more desirable because they tend to be liquid—and liquid fuels store more energy per volume than gaseous ones. For instance, propanol, which is liquid and contains three carbon atoms, stores more energy than methane, which is a gas and only has one carbon atom.

University, Australian firm collaborate for scientific research




University of Huddersfield scientist Dr Jason Camp is investigating the potential of a non-toxic, environmentally sustainable solvent produced from waste cellulose that promises to be a greener way to produce a wide range of medicines and other products. The project has also offered an exceptional opportunity for some of his most talented students to take part in cutting-edge, published research.
Camp – a senior lecturer in the University’s department of chemical sciences – has been collaborating with Australian-based firm Circa Group, which produces the solvent that it has named Cyrene (tm). Production of Cyrene is a joint venture between Circa and Norske Skog, the Norwegian pulp and paper manufacturer.
Many of the solvents currently used in chemical processes are problematic because they are toxic or pose environmental risks. In the search for more sustainable, safer processes, cellulose-based Cyrene has emerged as a strong candidate and is proving to be a viable replacement for the more toxic polar aprotic solvents (NMP, DCM, DMAC). The recent work undertaken by Camp and his team has shown it can be used as a solvent in the synthesis of ureas – chemical compounds that are highly important in fields such as pharmaceuticals and agrochemicals.
"The work Camp and his team are doing is an important step towards further “greening" the chemicals supply chain.” commented Circa CEO, Tony Duncan, "These are important markets, and with the ongoing demand from society for safer products and processes, work like this from talented researchers is practical and highly valued. These initial results have shown very promising results and we will now work with the team to take the research to a developmental stage"

Sabic unveils new Lexan resins for LED automotive lighting




Sabic said that it is introducing new materials for customers producing LED automotive lighting parts.
Lexan HF4010SR resin is one of the new offerings. This polycarbonate (PC) material can make it possible for customers to develop complex headlight bezels with enhanced aesthetics. Sabic has also added new grades to its existing Lexan XHT resin line, which can offer improved flow at high temperatures compared to other high-heat polycarbonate materials available today.
Sabic’s new materials targeting forward lighting parts come at a time when the complexity of these applications continues to increase. Current high-end LED headlamps weigh close to six kilograms with up to 200 components, thanks to the additional functionality they incorporate. Automakers are also striving to create highly distinctive lighting parts to help differentiate and increase the appeal of their vehicles.
Sabic has engineered the new Lexan resin to address customers seeking to produce complex headlamp bezels with enhanced styling, but at a lighter weight and at a lower overall system cost.
“These new offerings are examples of how we listen to our automotive lighting customers, stay in touch with their emerging needs, and propose materials they can consider to meet the challenges in front of them,” said Scott Fallon, global leader of Sabic’s automotive business.
New materials for complex headlamp bezels – Lexan HF4010SR resin
When designing injection-moulded parts, a low draft angle is important because it enables greater styling freedom as well as a larger optical surface. However, the lower this angle, the more problems arise with parts sticking in the mould, creating scuff marks and potentially even resulting in a part with cosmetic defects.
To help the industry meet this challenge, Sabic has developed Lexan HF4010SR resin. This material can enable customers to target draft angles between 0.5 and 1.0 degrees lower than the recommended draft angle for PC tools (typically between 3 and 5 degrees).
Bezels that are injection moulded in Lexan HF4010SR can be directly metallized (no need for priming) and gloss and reflectivity performance under high-temperature environments are both very good. The material has a unique wide processing window and high flow. Parts perform in environments requiring a maximum constant use temperature of up to 130°C.
