• What is deacidification system of crude oil refinery plant?
  • Deacidification system of crude oil refinery plant is for removing free fatty acids (FFA) from pressed or extracted crude oil.
  • Why is deacidification necessary in crude oil refining process?
  • Since FFA would produce irritating odor and accelerate the hydrolysis rancidity rate of neutral oil, deacidification is necessary and it has long been used as the greatest economic benefits for crude oil refining process, and the removal of FFA from crude oil is also the most difficult process in the crude oil refinery plant.
  • What are industrial deacidification methods?
  • Common industrial deacidification methods are alkali refining (chemical deacidification method), steam distillation (physical deacidification method) and solvent extraction (mixed deacidification method), the most widely used methods are alkali refining system and steam distillation method.
  • Does deacidification efficiency increase with 100 rpm?
  • Under the same conditions, calculated deacidification efficiency showed an increase with 28% (for 160 ¡ãC) and 20% (for 170 ¡ãC), for an increase in the wiper rolling rotations with 100 rpm, due to a uniform oil distribution on the evaporator walls facilitating the evaporation ( Figure 2 b). 3.2.3. Effect of Feed Flow Rate
  • Which deacidification method can reduce FFA from oil?
  • Solvent extraction is other feasible deacidification method to decrease FFA from oils and has the advantage of small oil losses, low energy consumption, gentle oil treatment, and reduced waste products. Methanol, ethanol, amyl alcohol, acetone, or acetic ester can be used as solvents [ 8, 9 ].
  • Does response surface methodology predict deacidification Efficiency & FFA concentration in deodorized oil?
  • Response surface methodology (RSM) was employed to formulate and validate second-order models to predict deacidification efficiency, FFA concentration, and triacylglyceride (TAG) concentration in deodorized oil based on three parameters effects, validated by statistical p -value < 0.05.
