1. Influence of Refinery Asphalt Residue Addition on Flow: A Study Using Waxy Model-System
One of the main phenomena causing problems in the oil industry is the precipitation of waxes, which can crystallize and form deposits, clogging lines and reducing flows. Many studies have been conducted seeking to overcome this problem, mainly through application of chemical to increase flow. Some studies have shown that the asphaltenes present in crude oil

2. Chemical Characteristics and Antioxidant Activity of Astaxanthin Extracted from Shrimp Residues Using Soybean Oil
Shrimp residues generated by the seafood industrial processing are generally discarded in the environment without any further treatment, leading to a loss of nutritional value such as proteins, lipids, chitin, carotenoids, and minerals. This practice can lead to environmental problems due to the decomposition of these substances in the air. The objective of

3. Effect of replacing beef fat with safflower oil on physicochemical, nutritional and oxidative stability characteristics of wieners
Abstract Five treatments of wieners were prepared with replacing 0, 25, 50, 75 and 100% of added beef back fat with safflower oil (SO). Changes in pH, thiobarbuturic acid reactive substances (TBARS) and color (L*, a*, b*) values of wieners were determined during manufacturing day and refrigerated storage (5, 10, 15, 20 and 30 d). Fatty acid profile, choleste

4. USE OF RESIDUES FROM THE CELLULOSE INDUSTRY AND SUGARCANE BAGASSE IN PARTICLEBOARDS
ABSTRACT The use of alternative materials such as lignocellulosic residues in the production of particleboards has increased considering that these residues are produced in large volumes and often do not have an appropriate destination. This research studied the use of residues from cellulose industries, sugarcane bagasse, and castor oil-based polyurethane r

5. Method for Cleaning Back-Produced Water from Polymer Flooding Operations to Determine Polymer Molar Mass Using Size-Exclusion Chromatography
One of the methods used by the oil industry to increase production is to inject water, containing polymer, into the reservoir. The viscosity of the aqueous solution is primarily responsible for the efficiency of this method, and is achieved using polymers with high molar mass. However, polymer degradation can occur during pumping and fluid displacement in th

6. Production of functional products using grape processing residuals
Abstract The viticulture – winemaking of Azerbaijan has a rich history and traditions. Grapes have been cultivated and wine made in these places since the ancient times. In the 1980s, the field was in a boom period and provided economic benefits at a level comparable to the country's oil industry revenues. Although the area is currently experiencing a rece

7. Kinetic Parameters of the Thermal Oxidation and Degradation Reactions in Soybean Oil and Palm Olein
Partially hydrogenated soybean oil and palm olein are oils that are widely used in the food industry. Continuous contact with air may cause changes of the triglycerides chemical structure, to eventually produce substances of lower molar masses that may be toxic to mammals. This study aimed to determine the kinetic parameters for the thermal oxidation of thes

9. Agar and pomegranate seed oil used in a biodegradable coating composition for Formosa papaya
Abstract The use of biodegradable coatings to conserve fruits and vegetables stands out in the food industry. This study aims to evaluate the postharvest quality of papaya Formosa 'Tainung 01' submitted to different coating formulations, to establish the one that best maintains the postharvest quality. The fruits, distributed in a completely randomized desig

10. EFFECT OF CYCLOPENTANE HYDRATES ON THE STABILITY OF DODAC AND AOT STRUCTURES
Abstract Hydrates are crystalline structures formed by water and substances with low molar mass molecules. Hydrate formation can occur during oil production when oil, gas and water flow through the same lines in conditions of high pressure and low temperatures. The deposition of hydrate crystals in production lines can severely jeopardize the safety of oper
