  • How does alkali refining reduce the loss of neutral oil?
  • During alkali refining, part of neutral oil reacts with caustic soda, i.e. is saponified, and goes into the soapstock, resulting in increased refining loss. Meanwhile, some neutral oil is also entrapped in soapstock and carried away. To reduce the loss of neutral oil and increasing refining rate, we shall choose the best-operating conditions.
  • What is chemical or alkaline refining?
  • In chemical or alkaline refining, an alkali is used to neutralise the FFA. Figure 1. Chemical and physical refining. Chemical refining is the traditional method used in past centuries. The main purpose of chemical refining is to saponify the FFA by an alkaline solution and dilute the resulting soaps in a water phase.
  • What is the refining process of soybean oil?
  • Soybean oil refining process: 1. Hydration Degumming & Alkali Refining Deacidification Process Neutralization: The crude oil is output by the oil feed pump from the oil tank, and enters the crude oil heat exchanger to recover part of heat after metering and then is heated to the required temperature by the heater.
  • What is chemical refining used for?
  • The neutral oils are subsequently bleached and deodorised. This chemical refining can be used for reliably refining virtually all crude oils, including oils of low quality, with the exception of castor oil. In addition to the removal of FFA other undesirable non-glyceride materials are also removed. These are mainly:
