An application of solid-phase extraction (SPE) for high-performance liquid chromatography (HPLC) analysis was developed for the rapid determination of benzoic acid and sorbic acid in Thai rice wine and distillate products. The SPE extraction gave promising results with 95.7+1.7% recovery for benzoic acid standard, and 95.2+2.3% for sorbic acid standard. Mean relative standard deviation (RSD) fo...

This study investigates the effect of ageing on the qualitative and quantitative composition of plum distillate in contact with oak wood chips. Maturation was performed with lightly toasted French oak (Quercus sessiflora and Quercus robur) chips or oak chips made from fragments of empty barrels that had been used for ageing cognac. The effects of oak chip dose, process temperature, ageing syste...

Abstract Human urine is a readily available nutrient source that can complement commercial fertilizer production, which relies on finite mineral resources and global supply chains. This study evaluated the effectiveness of simplified solar distillation process for to recover phosphorus (P) nitrogen agricultural use water non-potable purposes. Synthetic fresh, synthetic hydrolyzed, real hydrolyz...

This study utilizes ZrO2/Bagasse Fly Ash as a solid catalyst to convert Free Fatty Acid (FFA) from Palm Distillate (PFAD) into biodiesel. The fly ash was characterized by several physicochemical techniques, i.e., N

Production of fatty acid methyl ester (FAME) from palm fatty acid distillate (PFAD) having high free fatty acids (FFA) was investigated in this work. Batch esterifications of PFAD were carried out to study the influence of: including reaction temperatures of 70–100 1C, molar ratios of methanol to PFAD of 0.4:1–12:1, quantity of catalysts of 0–5.502% (wt of sulfuric acid/wt of PFAD) and reaction...

To understand partitioning of produced water (PW) constituents using thermal desalination, PW from the Delaware Basin was desalinated a crystallization process and modeled OLI Systems, Inc. (OLI, Parsippany, NJ, USA) chemistry software. The incorporation pretreatment step, steam stripping, prior to desalination predicted be effective at removing hydrocarbons (across range volatilities). As expe...
