How do you make acid oil from soap stock?

The soapstock is treated with caustic lye to saponify neutral oil and sent to Acidulation reactors for splitting. In these reactors, soapstock is mixed with sulphuric acid which liberates fatty acids and unreacted glycerides in the form of oily mixture known as Acid Oil.

What is soap stock used for?

Normally, soap stock is used to obtain acid oil with dark colour. Through this experiment, achieved oil get less colour equal to Soya oil and separated beta carotene can be used as a suitable colour for oils and margarines.

How is Soapstock made?

Soapstock is a byproduct of caustic refining which is usually acidulated to recover the fatty acids (34) whose composition is essentially the same as in soybean oil.

How is soya acid oil made?

Soya Acid Oil Product – sakthi soyas. The soap stock obtained during neutralization of soybean oil is collected in an acid proof vessel and acidified at an elevated temperature. The acidification results separation of fatty matter from the soap-water-oil mixture.

What is acidulated soapstock?

What does myristic acid do in soap?

Myristic is a saturated fatty acid that contributes hardness, cleansing, and fluffy lather. A lot of exotic oils contain high amounts of myristic acid, such as Murumuru Butter, Tucuma Seed Butter, Monoi de Tahiti Oil, and Cohune Oil.

What are soap stocks?

Definition of soap stock : the fatty material from which soap is made especially : the foots obtained in refining or hardening oils that contain chiefly fatty acids or their salts and oil.

Is soybean oil vegetable oil?

What is acidulation of soapstock?

The process is referred to as acidulation as an acid, usually sulfuric, is used to split the soapstock into its oil and water component parts. The fatty acid or acid oil phase is sold as a feed ingredient. The aqueous or acid water phase is discharged as waste. Herein lies the heart of the problem: disposition of soapstock, one waste product,…

Is it possible to produce acid oil from soapstock?

However, a new technology developed by Agrotech allows acid oil to be produced from soapstock withoutany accompanying waste. A zero-discharge process, it has the potential to dispose of the entire supply of soapstock produced both now as well as in the future. The technology creates a second, new, coproduct from the acidulation process.

What is soapstock from alkali refining?

Soapstock from alkali refining is a source of fatty acids, but it also presents a handling, storage, and disposal problem. It is generated at a rate of ˜6% of the volume of crude soybean oil caustic refined (Wang, 2002 ). Originally, many years ago, the caustic refining by-products were merely discarded.

Is environmental regulation impacting the disposition of soapstock?

However, with environmental regulation continuing to negatively impact the primary outlet for soapstock, disposition has become increasingly problematic. Compliance threatens to disrupt the supply disappearance balance with, perhaps, serious consequences for those unprepared for the future.
