• THERMAL OIL HEATERS



    Used in zones where the supply of natural gas, gasoil or fuel oil is easy.



    They realize a warming of thermal oil in closed circuit.



    They yield heat for convection to consuming machines inside a productive process.
  • ELECTRICAL HEATERS AND BOILERS



    They contribute heat by means of electrical resistances of very low density.



    Performance of 100 % of the emaciated energy.
  • WASTE HEAT RECOVERY UNITS



    Used in the installations of cogeneration.



    They take advantage of the latent heat in the gases of combustion of engines, turbines, incinerators,...
  • HEAT EXCHANGERS



    - Vaporizer: used for small consumptions of steam in facilities of thermal oil.



    - Interaccumulator waters down warmly: warm water tank sanitary in facilities of thermal fluid.



    - Interchanger oil - oil: warming of vegetable(plant) oils with thermal oil.

The white oils and their uses in the industry (II)

As I have already written in our previous blog, in this occasion we will enumerate processes in those white oils are used, being two the mainly ones:

as heat transfer fluid in installations in those the final products are for direct human consumption ,
as an oleic base of a final product that will be used directly by humans, and which we consider medicinal white oils.

In relation to the first topic, it is recommended the use of the white oils as heat transfer fluids in the installation of thermal fluid heaters, when the last ones are used with reactors, friers or equipments able to produce pharmaceutical products, food, etc., in order to avoid the alteration of the final product of human consumption during the production process, because of an accidental leak of a toxic thermal fluid.

According to the information that we have found, we think that there are two types of white fluids: the medicinal ones (base of products) and those used as heat transfers, both with low toxicity. If some reader agrees with the present statement, please confirm!!!!

In reference to the second subject, hereby we include a list of products in which medicinal white oils are present as base component:

Preparation of cosmetics:

- Cream, sun lotions and milks, ointments, paper impregnation, etc.
- Softening and moisturizers (oils and cleaner milks, lipsticks, powdered make-up);
- Products for children (shampoos and bathroom oils);
- Products for the hair care;
- As protective and neuter diluter for other ingredients of cosmetics, as essential oils; as anti-perspirants and deodorants in bar.

For their use in the food industry are added inhibitors of the corrosion:

- Unmolding in bakery products and pastries,
- Frying potatoes or chips, fruits as peanuts, etc… and ready or pre-cooked meals.
- Also used in treatment of rice,
- Emulsified oils for jams,
- Packaging of fruits,
- Conservation of eggs.

In the pharmaceutical industry, it has a high level of security due to:

- Their maximum purity (absence of toxic aromatic polyciclics and heavy metals),
- The complete destruction of germs in the process of production at high temperature,
- Used in specific procedures of packaging and manipulation: ingredients of the pharmaceutical ointments of topic use and petroleum jellies.
- It can be used as auxiliary element in the production of pills and in the production of capsules of jelly. The white medicinal oil is used in laxatives and liquid vaselines.

The white medicinal oils should satisfy the requirements of the regulation FDA defined in the clause 21 CFR 172.878 of the U.S.P. (USA), D.A.B. (Germany), B.P. (United Kingdom), CODEX (France) and Spanish Pharmacopea.

The white oils and their uses in the industry (I)

The raw oils are mixtures that contain thousands of different molecules. Because these complex mixtures are difficult to identify chemically, the oils are classified, according to the type of predominant hydrocarbon and their refinery process: paraffinical and naphthenics or aromatic.

The naphthenic oils are obtained directly from the refinement of the raw petroleum and they are practically free of paraffin (they only contain a 45%). This implies a constant flow of very low
temperatures, essential characteristic in several applications. To obtain "refrigeration grade" naphthenics oils, they should be put under complex physical and chemical treatments as unparaffin, bleach, elimination of sulphur, treatments with acids and solvents,...

The paraffinic oils possess a 75% of paraffin and only 25% naphthenic and aromatics.

Next, we will speak about the white oils, and their applications will be treated on the next number of this blog.

The white oil is obtained starting from paraffinic fractions of mixed base or naphthenic one, depending on the definitive use. The process is carried out for vacuum-distillation, followed by several refinement processes, included a final purification with catalytic regeneration. Their applications are specially important in products that have direct and forced contact with the human being, for what should be no toxic, not to stain and nor to contaminate.

The highest purity white oil is free of not saturated components: it is colourless due to the inert chemically nature of the hydrocarbons contained in. On the other hand, these oils are obtained with a process of hydrogenation by that the content of aromatics decreases to values smaller than 0.1%.

The white oils can be of two types: for technician or industrial use and for medicinal use.

The medicinal white oil is colourless, odourless and insipid and it has chemical and thermal great stability. It is liquid slight paraffin and an excellent lubricant that presents a good adherence and greasiness.
