A plume of contaminated groundwater stretches 15 miles underneath Phoenix. Some call the delay of a cleanup an injustice. Others see a "water grab." The chemicals in Phoenix soil and groundwater include: TCE, PCE and other toxic chemicals such as 1,1-dichloroethane.

THE BENEFITS OF CHEMICAL FOAMERS, AND HOW BEST TO USE THEM TO MAXIMISE PRODUCTION

Article | April 14, 2020

Downhole fluid build-up coupled with a drop in reservoir pressure can lead to the rapid decline of gas production rates, and can ultimately result in a well ceasing production. While there are many ways to deliquify a well to maximise production, chemical foamers can be incredibly effective and well worth considering. In this blog post, Kevin Lonie shares some of the benefits of using chemical foamers, and provides insights and advice around how best to use them… “Foamers are a much cheaper option than alternative solutions, such as mechanical lifts, and there is very little risk associated with their usage. If a foamer doesn’t work, it won’t make the well worse - so often we see clients giving them a go before opting for more expensive methods, in the hope that they produce the desired results. And we have seen their success over and over again.”

Resin and Polymeric Binders for Inks

Article | April 14, 2020

The market size for polymeric and resin binders in the global printing ink marketwas estimated to be over 1,200,000 MT in 2020, with a CAGR of about five percent. A major driver of this growth comes from the packaging industry, due to increases in consumer spending and online shopping, as well as demand for processed and packaged foods and beverages. In addition, increased use of water-based inks is promoting market growth, off-setting environmental and health concerns regarding solvent-based inks in addition to strict environmental protection policies. Water-based inks are projected to overtake solvent-based inks due to environmental regulations, the reduction of volatile organic compounds (VOCs) in the pressroom, and improvements in overall print quality. Ink formulations are complex mixtures, consisting of four basic component classes: pigments, polymeric binder resins, solvents or an aqueous dispersant media, and additives, such as surfactants, waxes, and rheology modifiers that enhance print quality. The purpose of the resin binder is to disperse and carry the ink pigment to the substrate, stabilize the pigment and additives dispersion to prevent settling, and provide print properties such as ink transfer behavior, setting, and drying characteristics. The binder also contributes surface appearance and gloss, strength and flexibility, chemical and solvent resistance, and also rub resistance. Ink binders can be categorized into the following polymer and resin types: acrylics, polyurethanes, polyamides, modified resins, hydrocarbon resins, and modified cellulosics.

Southeast polyolefins demand growth could be negative again in 2021

Article | April 14, 2020

BEFORE the pandemic, GDP growth rates in the developing world were always higher than in developed economies.And because developing economies had much lower levels of petrochemicals consumption than their rich counterparts, it meant that the multiples over GDP were higher than in the rich word, where consumption was pretty much saturated. For instance, polyethylene (PE) demand in a developed country such as Germany might have grown at 0.3% times GDP whereas in Indonesia the growth could have been one or more times higher than the rate of growth in GDP.But as The Economist wrote in this 11 July article: “In 2021 the poorest countries, which are desperately short of vaccines, are forecast to grow more slowly than rich countries for only the third time in 25 years.” Might the multiples over GDP growth also be adversely affected in the developing world, trending lower than the historic norms? They will almost certainly remain higher than the rich countries. But here is the thing: as millions more people are pushed back into extreme poverty by the pandemic or are denied the opportunity to achieve middle-income status, I believe that developing-world multiples may well decline.Escaping extreme poverty means being able to, say, afford a whole bottle of shampoo for the first time rather than a single-serve sachet, thereby raising per capita polymers consumption.

What the Coronavirus could mean for the global petrochemical industry?

Article | April 14, 2020

Coronavirus (covid-19) has developed rapidly and is already impacting significant parts of the global economy. Within this context the petrochemical industry is also being severely affected through short-term market uncertainties, pricing volatility and declining consumption in many of its key segments. The most visible outcome is emanating from China where economic activity has declined sharply in February and is forecast to remain low over the next few months. The effect of China’s economic slowdown is now resulting in consequences in other regions – “when china sneezes, the whole world catches a cold”.
