Crude Oil is Getting More Sour

The ‘sourness’ of crude oil technically refers to its hydrogen sulfide (H2S) content before processing. Crude can naturally contain up to 14% sulfur content by weight, but this percentage is comprised of myriad sulfur compounds; only a small ratio is H2S. Unfortunately, even very low levels of H2S in crude can cause excessive corrosion and degrade catalysts in the refinery. Continue reading “Crude Oil Is Getting More Sour.

Why Measure Bisphenol A Continuously in Effluent Water?

BPA analysis in water

The BPA Controversy, In Brief

The international fight over banning Bisphenol A from use in consumer products has now spanned decades with no sign of either side backing down. BPA is known to mimic estrogen in the human body, but the strength of its effects and the levels of real exposure are heavily disputed. Studies have variably linked BPA to male infertility, breast cancer, and behavioral disorders, fueling concern among the scientific community and wary shoppers alike.

However, BPA is quite entrenched as industry’s chemical of choice for strengthening polycarbonate plastics and producing resins—4.6 million tons of it were manufactured globally in 2012, a figure that will only rise with demand from emerging markets. While some regulatory legislation has been successful, particularly in banning BPA-constructed baby bottles due to infants’ heightened susceptibility to low-dose effects, we still live in a world that will likely continue producing BPA on a massive scale for decades to come. The question, then, is what can we do to effectively mitigate exposure in our communities? Continue reading “Why Measure Bisphenol A Continuously in Effluent Water?”

Will Li-S Batteries Change the Economics of Sulfur Recovery?

Li-S batteries and sulfur recovery

The Advent of Lithium-Sulfur Batteries

With slow progress in electric vehicle driving range and smartphone stamina, the limitations of current lithium-ion (Li-ion) batteries have become glaring. First commercialized by Sony in 1991, the now dominant Li-ion technology is struggling to improve the performance of the existing chemistry, its incremental gains outpaced by consumer demand. As the next breakthrough in battery design is hotly anticipated, one technology shines with promise due to superior performance and the practicality of its materials: Li-S.
