Effects of temperature, flow rate, number of stages and a heads column on congener removal in fuel‐ethanol distillation: a simulation study

Journal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND Industrial fuel‐ethanol units must remove trace volatile congeners (acetaldehyde, ethyl acetate, carbon dioxide) to meet quality requirements. In Brazilian systems, a small heads column (“Column D”) is often placed above the stripper.

Optimization of light spectrum and intensity to enhance growth and metabolite profiles in green and purple radish microgreens cultivated in a vertical farming system

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Microgreens have emerged as a promising crop in vertical farming due to their high nutritional value and short growth cycles. Light spectrum and intensity are critical factors influencing biomass production and metabolic activity in plants, particularly in controlled environments such as vertical farming systems. This study aimed to
