Palm oil refinery, 50t dry degumming crude palm oil refinery. The dry dugumming is popular for palm oil refining, it is widely used, also matched with dry fractionation process. We will intoduce the palm oil refinery in the following parts.

Degumming process

The main purpose of this step is to remove the crude oil in the presence of non-fat ingredients, instead of using dry degumming centrifuge new process:

After filtration of crude oil through the oil was heated to 40-45 degree, the amount of oil added to the oil in a concentration of 0.1-0.15% concentrated phosphoric acid about 85% of the fully reacted for 30 minutes, so that the gum granulation. Add silica gel (0.1% of oil) under vacuum, stirred and heated to 105 degree, utilizing decolorizing filter waste clay to silica gel entrapment.

Bleaching process

The main purpose of bleaching step is to remove pigment present in the crude oil, residual oil and the soap and the like. Bleaching process includes the following phases:

Bleaching

And in oil in a stable flow rate control through the use of low-pressure steam heater is heated to 105 degrees, and is sent to the vacuum bleaching column. When oil enters Bleaching tower, which, by the ratio of bleaching earth mixer, add bleaching earth is driven by an electromagnetic governor quantitative auger is completed, the bleaching earth can be flexibly adjusted according to the requirements of the added amount of raw oil and oil products.

The company design and manufacture of "layered Continuous Stirred steam Bleaching tower", the layer structure effectively reduces the occurrence of a short circuit materials to ensure that the decolorization time; steam "circulation" stir not happen "dead" phenomenon, active clay mixed with oil, to avoid air leaks caused by mechanical agitation, reducing the oxidation of fats, no moving parts, no reserve seals and spare parts mechanical transmission devices; effective guarantee continuous bleaching time ;

Bleaching earth with an electric hoist systems delivered to the staging clay pot, bleach eatth ratio for use.

Filtering

From Bleaching tower oil to clay and the mixed oil is pumped into decolorization filter, and then enter the fine filter, where the clay is blocked with solids, filtrate (clear oil decolorization) decolorizing the oil is transferred to temporary storage tank.

In this system, there are two decolorization filter, there is always a state in the filter, and the other is at the emptying and cleaning up the state. When in emptying and cleaning times are squeezed steam filter, oil filter so that most of the inside is purged to decolorization tanks, a small part of clay mixed with oil were discharged into the steam brake Crone / sewage tank cake with steam dry, dry periods in the filter gather leftover oil and condensate have been discharged into the sewage tank, and finally dry filter cake at the bottom of the machine through the discharge valve, pneumatic vibrator dumped into the waste clay room.

Residual oil pollution within the tank is pumped back Bleaching tower reworked.

Leaf filter in parallel to achieve continuous process, the oil cooler filtered after cooling and security filtering into the middle of the tank to be dewaxed.

Deodorizing process

The main purpose of deodorization process, is to remove the decolorization of free fatty acids present in the oil, low molecular weight substances. From the filter to the decolorization of oil is stored in the decolorization tank, the tank is designed to operate in vacuum conditions, from the tank, the oil is pumped into the decolorization deodorization section.

Flow into the deodorization section of decolorization of oil through a flow controller, a series of oil through the heat exchanger is heated to about 250-260 degrees deodorization temperature.

When the oil is heated in the final oil heater, entering the deodorization tower where a portion of the low boiling point of free fatty acids and other volatiles are evaporated.

Deodorization tower is divided into the washing area, distilled and deodorized regional area.

In the wash zone, a free fatty acid distillate is recycled from the top stream is condensed rising gas used in free fatty acids and other condensables. Condensed distillate is collected in the fatty acid staging tank, where the fatty acid for recycling: cooling the fatty acid distillate in the cooler and then recycled to the top of the fatty acid trap. Fatty staging tank level is controlled by manual drain.

In order to reduce fatty droplets carrying gas into the vacuum system and the seal pool and circulating pool on trap fitted with a defogger.
