Refrigeration oil and other materials used with refrigerant for refrigerators or air conditioners should have thermal and chemical stability to maintain the system reliability. Some kinds of synthetic oil are used for alternative refrigerant, HFC’s and hydrolysis, material compatibility, and low-temperature extraction of contaminant or sludge are important subjects. Much more numbers and times ...

Background: The level of free fatty acids (FFAs) is an important oil quality index that consistently measured at mills and refineries to ensure palm within specification limits. FFAs can accumulate any point throughout the process, for example, during fresh fruit bunch (FFB) harvesting or mill process before sterilisation. Another key contributor FFA build-up loose (LF), which collected followi...

Efficient observation means are required for supporting operational fight against oil pollutions at sea and recovering operations, including reliable choice and guidance of maritime and airborne fighting means. Among the suite of sensors available, the potential of airborne passive hyperspectral imagery and active fluorescence laser systems for remote sensing of oil spills at sea have been stud...

This study was conducted to investigate the effects of processing aids and techniques such as talcum powder (2% w/w), calcium carbonate warm water dipping (45 °C), combined treatment (warm dipping+2% carbonate) control (without adding aid) on extractability quality ‘Tarom 7’ olive oil randomized complete block design with three replicates. The results showed that there were no significant diffe...

Abstract Hydrocarbon processing from extraction to the final product is an important aspect that needs optimised technology for consumption-led market growth. This study investigated real data oil facility and analysed simulation model entire crude unit based on process system engineering using Aspen HYSYS. The mainly emphasises optimisation in hydrocarbon maximum yield of with less energy cons...

most reservoir fluids contain heavy paraffinic compounds that may precipitate as a solid or solid like material called wax if the fluid is cooled down. wax precipitation is a phenomenon of considerable importance in oil industry. an increase in aggregation results in enhanced oil viscosity. this however causes significant negative effects on production, transportation and processing of crude oi...

When a large oil or gas field is produced, several reservoirs often share the same processing facility. This facility is typically capable of processing only a limited amount of oil, gas and water per unit of time. In the present paper only single phase production, e.g., oil production, is considered. In order to satisfy the processing limitations, the production needs to be choked. That is, fo...

Palm oil contributes about 19% of worldwide vegetable oil production with Malaysia accounting for over 50% of total production. Due to the global rise in crude oil prices, scientists have been forced to look for cheaper alternatives and palm oil has provided the right platform. This in turn led to an increase in the oil plantations and production in countries such as Malaysia, Indonesia and Tha...

To recycle post-consumer HDPE contaminated with waste lubricating oils, companies include prior washing and drying in the process. This consumes large amounts of water and energy, generates significant effluent requiring treatment. This study assesses lubricating oil influence on HDPE properties to evaluate the feasibility of its direct mechanical recycling without washing. The current lubricat...
