Abstract

1. A method of obtaining 1P heater oil from heavy products of crude oil processing by way of entering from 1 to 25 percent by weight of the additive lowering the kinematic viscosity, characterized in that the mixture of diesel oil with sulphate turpentine or its fraction in the amount of 1 to 25 percent by weight is entered into the heavy fraction of crude oil in the amount of 75 to 99 percent by weight.

Description

The subject of the invention is a method of obtaining fuel oil 1P from petroleum products.

The heavy fractions obtained from the processing of crude oil are used as Euro trees for the production of heating oils, including fuel oil 1P. One of the requirements for 1P fuel oils is to have a relatively low kinematic viscosity at 50 ° C. The viscosity ^{of the} right ^and uzys ^k kissing s ^ble by mixing them Ci.E ^ ^f ra ^c tion. rop ^y to ^f towej oil fraction as paroxysmal lowering viscosity. However, diesel fuel is a scarce and relatively expensive product.

The aim of the invention is to develop a method for the production of 1P fuel oil using sulfate turpentine or its derivatives.

During the conducted research, it was surprisingly found that it was possible to obtain fuel oil 1P with the required properties by replacing any part of diesel oil with sulphate turpentine or products obtained from its processing.

The method according to the invention consists in introducing into the base;) heavy oil fraction in an amount of 75 to 99% by weight. a mixture composed of diesel oil and sulphated turpentine or its fractions in an amount from 1 to 25% by weight, the ratio of diesel oil to sulphated turpentine or its fractions in the mixture from 1: 99 to 99 <1.

The sulfate turpentine fraction may be a cubic residue from the first or second distillation of oxidized sulfate turpentine, a fore and a second distillation of oxidized sulfate turpentine, a fore from the oxidation of raw sulfate turpentine, or a mixture of the said fractions.

The method according to the invention makes it possible to utilize hitherto unused waste from the disposal of sulphate turpentine, and thus to save diesel fuel. An additional advantage is the protection of the environment thanks to the lower sulfur content in the fuel oil.

The fuel oil 1P obtained by the method according to the invention, even in the case of complete replacement of the diesel fuel with sulfate turpentine or its fraction. It is homogeneous and does not precipitate even after long-term storage.

The method according to the invention is shown in the working examples.

Example 1. For the crude oil base fraction in an amount of 75 wt.%. a mixture of 20 wt.% was added. diesel oil and 5 wt. a fraction of sulphate turpentine called still oil, which is a cubic residue from the 1st distillation of oxidized sulphate turpentine.

Example II. To the heavy crude oil base in an amount of 75 wt.%. a mixture of 2C wt.% was added. % diesel and 5 wt. the fraction of sulphate turpentine called carne turpentine, which is a cubic residue from the 2nd distillation of oxidized sulphate turpentine. After stirring a homogeneous oil 1P of kinematic viscosity] 4 ⁸ 0 at 50 ° C.

Example III. To the heavy crude oil base in an amount of 75 wt.%. 20 wt% meshes were added. % diesel and 5 wt. of the sulfate turpentine fraction of the steno turpentine, the foreruns from the distillation I and II of oxidized sulfate turpentine were mixed, obtaining a homogeneous liquid with the properties given in table

Example IV. About 75 wt% heavy crude oil base. a mixture of 20 wt.% was added. % diesel and 5 wt. the sulfate turpentine fraction constituting the forerun from the oxidation of raw sulfate turpentine and mixed to obtain a homogeneous liquid with the properties required for fuel oils.

EXAMPLE 5 With a heavy crude oil base of 75 wt.%. a 20% watt mixture was added). % diesel and 5 wt. the sulfate turpentine fraction constituting a blend of the sulfate turpentine fraction 1 mentioned in Examples 1-4 was mixed to obtain a homogeneous liquid with the properties required for fuel oils. The table attached shows the properties of the fuel oil mixtures 1P obtained according to the invention in comparison with the fuel oil 1P according to the standard ΖΝ-66 / ΜΡΟ3ιθιι1νΡ-1 (Χ).
