US3947602A - Treatment of cooking oil - Google Patents
The useful life of cooking oil is increased by treating the cooking oil with a food compatible acid to counteract the adverse effect of food juices which are dissolved in the cooking oil. The cooking oil is generally also contacted with a suitable adsorbent, such as an activated carbon, to adsorb soluble oxidized and/or pyrolytic contaminants.

refining or degumming, and prepares the oil for the final deodorization process. In the case of crude palm oil, bleaching is the initial stage of the whole refining process. At first glance, bleaching seems a relatively simple process that consists of mixing the oil with a powder, stirring for some minutes and then removing the powder again.
Vegetable oil refining
Vegetable oil refining is a process to transform vegetable oil into biofuel by hydrocracking or hydrogenation. Hydrocracking breaks big molecules into smaller ones using hydrogen while hydrogenation adds hydrogen to molecules. These methods can be used for production of gasoline, diesel, propane, and other chemical feedstock.

Energy and Exergy Analysis of a Vegetable Oil Refinery
Energy and exergy analysis was conducted for a vegetable oil refinery in the Southwest of Nigeria. The plant, powered by two boilers and a 500 kVA generator, refines 100 tonnes of crude palm kernel oil (CPKO) into edible vegetable oil per day. The production system consists of four main group operations: neutralizer, bleacher, filter, and

Edible Oil Refining Processes – Degumming / Neutralization
The oil normally becomes cloudy in 5–6h but with proper dewaxing the oil remains clear after 24h of storage at 0˚C. The following steps are used to dewax sunflower oil: Crude oil is refined and bleached to low phosphorus (<1ppm) and low moisture content (<0.1%). The oil is heated to 55˚C to make sure the oil is fully liquid.

Physical Refining – Bleaching | Oil Palm Knowledge Base
Bleaching Bleaching was introduced in edible oil refining at the end of the 19th century to improve the colour of cottonseed oil. Originally, it was a batch process at atmospheric pressure, in which natural bleaching clay was added to hot oil with the sole objective of removing colouring pigments. Today this is no longer the…

After large floating solids are removed in the grid-oil separator tank, the raw water flows into the lagoon, where it is oxidized and decomposed by the activated sludge therein. As the lagoon is 20,000 m3 in total capacity and uses 5 days detention time, the BOD-MLSS load is 1/5~1/10 of the conventional activated sludge process. The endogenous
