A smart chemoenzymatic method detects and removes hazardous phenols

Phys | August 08, 2019

Many industrial and agriculture processes use chemicals that can be harmful for workers and the ecosystems where they accumulate. Researchers from Thailand have now developed a bioinspired method to detect and detoxify these chemicals in only one step. As they report in the journal Angewandte Chemie, a combination of two natural enzymatic reactions convert harmful chloro- and nitrophenols into the substance that causes the characteristic glowing of fireflies: luciferin. Oxygenated benzene or phenol molecules are part of the chemical structure of many organic substances, from lignin and tar, to pharmaceuticals, dyes, and herbicides. Phenol-derived compounds are added to plastics as plasticizers. Although many of these chemicals are not harmful as such, pesticides, herbicides, or flame retardants may degrade to cancerous and stable nitrophenols and halogenated phenols that accumulate in the workplace or in fields.

Viridis Chemical Announces Completion of Capital Improvement,and Begins Construction on Upgrade to Produce Bio-Based Ethyl Ace.

Viridis Chemical | September 13, 2021

Viridis Chemical, LLC a manufacturer of renewable chemicals, announces the completion of the Phase I capital improvement to produce USP grade bio-based ethanol and the commencement of the Phase II capital improvement to produce bio-based ethyl acetate at its plant in Columbus, Nebraska. As previously disclosed, Viridis Chemical partnered with HELM U.S. Corporation in an exclusive Global Marketing Partnership regarding the products produced at the Columbus, Nebraska, plant and Koch Project Solutions, LLC ("KPS") to design and construct its two-phase capital project. Viridis Chemical began USP grade bio-based ethanol production in early August 2021 at the Columbus, Nebraska, plant. On specification product for USP grade ethanol has been achieved and the first railcars have been sold to Viridis Chemical's marketing partner, HELM. In addition to starting USP production, Viridis Chemical and KPS initiated construction on the Phase II capital improvement to produce bio-based urethane grade ethyl acetate and expects to begin production of that product the first quarter of 2023. Carl Rush, co-founder and CEO of Viridis Chemical, stated, "This is a huge first step for our company as we bring our USP grade bio-based ethanol product to market. We will now shift our focus to executing on our ethyl acetate expansion project. Upon completion of our ethyl acetate expansion project, we will be the first and only large-scale producer of bio-based ethyl acetate in North America and look forward to providing the domestic as well as global market with sustainable ethyl acetate for a variety of applications, including several consumer-facing products." "We are extremely pleased that Viridis Chemical has begun USP ethanol production and look forward to being able to provide sustainable volumes of USP ethanol to our broad customer base. This is an exciting milestone for the partnership between Viridis Chemical and HELM and we look forward to the continuation of our relationship when the ethyl acetate unit is online," said Björn Steckel, President Chemicals Americas of HELM. Paul Switzer, President of Koch Project Solutions, said, "We're pleased to partner with Viridis Chemical to help them achieve their Phase I milestone and are excited to continue working with them as they move onto Phase II. We expect Phase II to be operationally ready by early 2023." About Viridis Chemical Headquartered in Houston, Texas, Viridis Chemical, LLC is a world-class manufacturer of renewable chemicals.

Honeywell technology helps Hengli Petrochemical reduce nitrogen oxide and carbon emissions

Honeywell | January 14, 2021

Hengli Petrochemical Co. Ltd has effectively utilized Callidus burner innovation from Honeywell UOP to limit nitrogen oxide (NOX) and carbon monoxide (CO) discharges in China, and decrease the effect of these outflows while guaranteeing protected and stable tasks. Hengli chose Callidus progressed flares and low-NOX burner innovation in 2017 to follow ecological guidelines and improve energy productivity and operational wellbeing at its treatment facility and petrochemicals complex in Dalian, Liaoning Province. Furnished with imaginative low fire mode (LFM) innovation, Callidus burners decreased Hengli's emanations, improving air quality and assisting with killing reasons for corrosive downpour. At the point when heater temperatures are beneath 650°C, the NOX burner produces more significant levels of CO. However, by utilizing the LFM innovation, the Callidus burners kept outflows at ideal levels – with NOX and CO each under 50 mg/Nm3. This assisted Hengli with taking care of an industry issue of limiting both NOX and CO outflows to diminish natural effect, while guaranteeing protected and stable activities. "We chose the Callidus innovation since it's the worldwide pioneer in ignition advances and on the grounds that it was the first in China to address the CO outflow issue in a NOX burner," said Liang Peng, Static Equipment Director, Hengli Petrochemical. "Callidus burners likewise can be supplanted without requiring a closure of the heater and different tasks." "Our involvement in these innovations around the world assists clients with preferring Hengli create monetary incentive by improving their rate of profitability with ecologically stable items," said Xiang Lei, VP and senior supervisor, Honeywell UOP China. "We're satisfied to work with Hengli to improve its energy effectiveness and operational security."
