extraction

Research of grinding degree influence and polar solvents nature on the efficiency of oil withdrawal from vegetable raw material using extraction method.

The article presents results of experimental data of a study of the extraction process of vegetable oil from soybean and rapeseed in a stationary layer, held using a Soxhlet apparatus. Polar solvents such as methylene chloride and ethanol were used as the extractants. The influence of the grinding degree of the particles of vegetable raw material on the oil yield were investigated. Solvents’ nature impact on the efficiency of the processis established. The results of quantitative analysis are presented in the form of graphical dependencies with the presence of basic process parameters.

Oil extraction from the sunflower seeds, mechanism and kinetics of the process

The results of the research of extraction of oil from the none-crushed and crushed sunflower seeds of different fractions by the method of extraction are presented. The mechanism of extraction and process kinetics is investigated. It has been shown that the process of extracting oil from sunflower seeds is complex and consists of both intra-diffusion and external-diffusion transfer of oil. It is stated that the process is similar to the extraction of the target components from the seeds of most types of plant raw materials.

PROBLEM OF DISPOSAL OF ORGANOCHLORINE WASTE OF VINYL CHLORIDE PRODUCTION

The sources of organochlorine waste formation, its toxicity, and environmental impact are analyzed, and methods of its disposal are considered. The composition of insoluble compounds in the stillage residues of the dichloroethane rectification stage before incineration is determined, and the method of their extraction is proposed.

Kinetics of Ultrasound-Assisted Extraction of Anthocyanin from Purple Roselle Calyces under different pH Conditions

This research presents that the higher temperature results on higher extracted anthocyanin. In addition, it was found that pH 2 was preferable for obtaining greater anthocyanin content. Employing the second-order kinetics model in this research confirmed the good fitting of the model and experimental data.

Acid Hydrolysis and Ethanol Precipitation for Glucomannan Extraction from Crude Porang (Amorphophallus Oncophyllus) Tuber Flour

Extraction of glucomannan from crude porang flour by acid hydrolysis and ethanol precipitation was studied. Effects of acid concentration, temperatures and time were investigated, kinetics model of the process was developed and the parameters were evaluated based on experimental data. New data on yield and purity of glucomannan under various conditions were obtained.

DEVELOPMENT OF THE PROCESS OF EXTRACTION OF CORN GLUTEN

The processing of corn grain allows getting starch, roughage, oil and proteins. Corn gluten is a valuable product that is obtained from corn processing to starch and molasses.  It is a pure protein that it has excellent nutritional properties. Corn gluten is not as widely used as wheat gluten. It’s mainly used for feeding farm animals and poultry, and has a short shelf life. The secondary processing of corn gluten is relevant. Besides solution of a number of environmental problems we can get a number of important products such as zein and fat-carotenoid fraction.

EXTRACTION OF SOLUBLE SOLID PHASE FROM THE POROUS INERT ENVIRONMENT

The study of the extraction process of the target components contained in the layer of grain material is presented. The process concerns the dissolution of solids from the outer surface of the solids and the extraction of the dissolved material from the layer of inert grain material in the stationary layer.

Створення нового технологічного процесу повного перероблення розчину стебницького хвостосховища у кондиційні продукти – натрію хлорид і бішофіт

In this article the new technological process of complete processing of solution Stebnik’s tailings on the basis a complex experimental researches, which involves the use of standard equipment, is developed. It enables to get two conditioned products (sodium chloride and bishofit) and potassium-magnesium fertilizer. The cyclic using of organic extractant in the process enables dramatically reduce material costs of processing tailings solution and provides ecological completeness of the process.

Екстрагування хлоридів із суміші хлоридних і сульфатних солей застосуванням етанолу

In this article the extraction of chloride from a mixture of sulfate-chloride salts by aqueous organic extractant with ethanol was investigated. It is found that using of the ratio of T:P = 1:2 and the concentration of ethanol in the extractant 50 wt. % сan get a satisfactory yield chlorine-free product that meets to potassium-magnesium.
