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

Article | July 20, 2022

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.”

We can solve the plastic waste crisis but we don’t have much time

Article | June 6, 2022

IN 2015, a global agreement was reached that 8m tonnes a year of plastic waste entering the oceans was unacceptable, according to this September 2020 article in The Conversation. This was the amount of plastic that was estimated to have ended up in the oceans in 2010. “Several international platforms emerged to address the crisis, including Our Ocean, the UN Sustainable Development Goals and the G7 Ocean Plastic Charter, among others,” continued the article. But in 2020, an estimated 24m-34m tonnes of plastic waste was forecast to enter our lakes, rivers and oceans. This could reach as much as 90m tonnes in 2030 if the current trajectory continued, said The Conversation. This is the type of information out there, free to view on the internet and accessible via a very quick Google search, representing a major challenges for our industry. I cannot of course verify the numbers. But they are out there. Also out there is a May 2019 article by the World Economic Forum (WEF), which provided a good summary of research into what experts believed was the scale of the waste problem in the developing world.

Resin and Polymeric Binders for Inks

Article | July 14, 2022

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.

Application of Chromatography in Various Industries is Changing the Game!

Article | August 8, 2022

Used to separate and analyze compounds into their various components— chromatography plays a crucial part not just in the food industry but in the realms of drug testing, forensics, and even quality control in our favourite alcoholic drinks as well. Advanced Chromatography is an analytical technique introduced to the world by chromatography instrument companies to separate and analyze individual chemicals from complex compounds. Recent developments in the biotechnology and pharma industries have created a significant surge in the chromatography market. Read on to find out five fascinating facts about the day-to-day applications of chromatography in various industries and why businesses are looking to invest more in OEM chromatography manufacturing. Why are Industry-Decision Makers Adapting to Chromatography? Liquid Chromatography; A Popular Choice in Drug Testing Today, a lot of drug tests use liquid chromatography-mass spectrometry because it is easy to use, widely available, and gives quick results. LC and LC-MS can be done in almost any testing facility, which is different from other methods. It can be run by people with little training, so a testing facility can hire mostly technicians instead of highly trained scientists, who are harder to find. LC-MS is also very accurate, which means that there are fewer false positives. With liquid chromatography, you can get results in about 10 to 30 minutes, which is very fast. This technology is used by many drug testing labs across the country. It is widely used and trusted for testing drug samples and many other things. Businesses associated with the sports industry are leveraging chromatography to effectively and accurately test athletes for doping or performance-enhancing drugs. Use of HPCL in Pharmaceutical Industries Chromatography is used in the medical and pharmaceutical industries to create vaccines. In addition, chromatography can determine which antibodies best neutralize viruses and diseases. Mapp Biopharmaceutical, Inc. used the chromatography technique to develop the experimental immunization Zmapp to counteract the deadly Ebola virus. And it is still being used today to fight the coronavirus. The pharmaceutical industry has gained enormous success by exclusively using HPLC to obtain precise results during drug trials. The results can be used to analyze finished drug products and their ingredients quantitatively and qualitatively during manufacturing. The Detector in Forensic Science Chromatography methods are a well-established, powerful suite of methodologies in forensic science, from drug busts, murders, and robberies, to the identification of a plethora of chemical compounds that may be present in samples from terrorist incidents. Forensics use gas chromatography to help solve crimes. It helps analyze blood and clothing samples, allowing forensic scientists to investigate who and what was present at a crime scene. In particular instances, chromatography can even help forensic scientists pinpoint the exact whereabouts of the alleged perpetrator and victim before the crime happened. It’s an error-free process. Therefore, it is incredibly helpful in court. Additionally, chromatography is extremely handy in arson investigations. Most fires have a virtual cocktail of different substances. Every compound and substance differs in size and weight. Chromatography helps break down these varying compounds and substances to help determine what exactly started the fire. Liquid Chromatography in Food Industry Liquid chromatography plays a vital role in the food industry nowadays. It absolves and permits the selective removal of a wide variety of flavor and non-flavor-active food ingredients. The USDA, along with other countries, has prioritized rigorous testing of processed meat's contents. For example, in 2013, it was found that horsemeat was being sold as beef without anyone noticing. As a result, the food industry decided to change its analytical techniques. Chromatography quickly became the best way to find out what was in processed meats. High-Performance Liquid Chromatography and mass spectrometry were used to ensure that meat labeled beef was actually beef. In addition, it could tell if horse meat was mixed in with the beef, which helped keep people safe. Bio-Rad Fast Acid Analysis Column in Beverage Testing Not just food, many beverage manufacturers also use chromatography to ensure that each bottle of their product is the same. But, again, consistent taste is the main priority. And knowing the exact content of each bottle is the most proactive way to measure things. The Bio-Rad fast acid analysis column has been successfully used by many companies to quantitatively determine vitamin C in juices, fresh drinks, and powdered drinks. Chromatography Market is Opening New Dimensions in Various Businesses Undoubtedly, technological advancement has created a vigorous need for chromatography devices. According to Verified Market Research, growing at a CAGR of 3.4% from 2020 to 2027, the chromatography market is projected to reach USD 4.73 billion by 2027. The chromatography instrumentation market is currently witnessing huge advancements in the design of columns. This is raising the demand for development of better analytical reagents and resins. Increasing collaborations among the existing players, specifically in the Asian market is another propelling factor for this market. Additionally, emergence of green chromatography, increasing usage of chromatography instruments for monoclonal antibody purification, and usage of nanomaterial in chromatography are also fuelling the growth of this market. Plus, increased government funding in research and development activities is further driving the market growth. With various pharmaceutical and biotechnology companies, chemical, food and beverage, and other industries contributing to its market growth, one thing is for sure— the increase in the chromatography system market is here to stay.

NRDC and Partners Calls out EPA for Evaluation Process of Toxic Chemical Risks

NRDC, EPA | July 17, 2020

NRDC (the Natural Resources Defense Council) together with partners, today asked a federal court to review the Environmental Protection Agency’s woefully inadequate process for evaluating risks of the toxic chemical methylene chloride. A solvent used in paint strippers and other products, methylene chloride has already been linked to some 60 deaths, at least 4 of which occurred after the EPA refused to finalize a ban on its use in paint strippers. “This is the agency’s very first risk evaluation under the updated federal toxics law and it sets the stage for future limits on this deadly chemical,” said Selena Kyle, senior attorney and managing litigator for NRDC. “But the agency has underestimated the risks to people exposed to methylene chloride on the job, and all but ignored risks to people who live near facilities that release it into the air, water, and soil. When EPA moves forward to regulate the chemical, it must consider these risks.”

Research finds potentially toxic chemicals used in smartphones and TVs escaping into environment

CBC | December 17, 2019

An international research team is sounding the alarm about potentially harmful chemicals — used to manufacture screens for devices like smartphones and TVs — being found in homes and other buildings even when the devices aren't present. In a paper published this month in the Proceedings of the National Academy of Sciences, researchers found chemicals called liquid crystal monomers in household dust samples collected in China. That's problematic, because the chemicals are supposed to stay contained within the screens. "They're supposedly sealed in the screens when they're made, but obviously they do come out," said Prof. John Giesy, a Canada Research Chair in Environmental Toxicology at the University of Saskatchewan.

New material captures and converts toxic air pollutant into industrial chemical

EurekAlert | November 22, 2019

An international team of scientists, led by the University of Manchester, has developed a metal-organic framework, or MOF, material that provides a selective, fully reversible and repeatable capability to capture a toxic air pollutant, nitrogen dioxide, produced by combusting diesel and other fossil fuels. The material then requires only water and air to convert the captured gas into nitric acid for industrial use. The mechanism for the record-breaking gas uptake by the MOF, characterized by researchers using neutron scattering at the Department of Energy's Oak Ridge National Laboratory, could lead to air pollution control and remediation technologies that cost-effectively remove the pollutant from the air and convert it into nitric acid for use in producing fertilizer, rocket propellant, nylon and other products. As reported in Nature Chemistry, the material, denoted as MFM-520, can capture atmospheric nitrogen dioxide at ambient pressures and temperatures--even at low concentrations and during flow--in the presence of moisture, sulfur dioxide and carbon dioxide.
