SU45371A1 - Bitumen transport method - Google Patents

Description

The proposed method of transporting petroleum bitumen consists in that high-melting bitumen is cast in the form of tare, which is filled with low-melting bitumen, and in general, the whole composition gives the bitumen of the required grade when melted.

The advantages of the proposed method are as follows:

1. The need for any container currently used for the transportation of bitumen (wooden barrels, iron cans, cistern-thermoses) is minimized, which significantly reduces the cost of production and saves a large amount of scarce materials and labor.

2. The profitability of all kinds of transportation is increased.

5. The year-round operation of the plants is ensured without any decrease in productivity depending on climatic conditions.

4. The consumer is exempt from a number of operations that take place for containerized goods, such as the need to care for and store the container. In order to carry out the proposed process, the high-melting bitumen prepared in the usual way from the digester is transformed into a state of plastic by cooling, and for the rapid cooling of the bitumen pickup.

There are suitable methods and devices both existing in industry and specially adapted.

Such methods, for example, can be:

a) cooling the hot bitumen with water directly. By adjusting the jet of bitumen discharged from the boiler into a sufficient amount of water, it is possible to achieve the transition of a liquid form into a plastic or solid state in a short period of time without the risk of overshoot. Water can serve as a conveyor;

b) cooling hot bitumen in a tubular refrigerator.

c) cooling on rollers. The stream of hot bitumen is distributed on the surface of rotating in different directions drums cooled from the inside with water. Bitumen is obtained in the form of plastic tape, strips, etc.

Thus, choosing one or another method of cooling, bitumen can be transferred from a liquid to a plastic state.

The resulting plastic material enters the press compartment receivers by mechanized means.

The receivers serve as "production buffer for the new material processing stage, and also can partially perform independent operations: specify the temperature required for

converting the material to a plastic state by adjusting the temperature or drying the material in the case of using a hydraulic conveyor.

In this and in the other case, the design of the receivers does not go beyond the area commonly used. The chamber of the receiver for temperature control is equipped with surface heaters or coolers of simple structures, using the usual parameters as a heat carrier and a coolant of water vapor and water. Drying can be done by air blowing.

From the receivers, the plastic material is fed mechanically to the presses of the pressing section, the latter mainly performing three operations: one part of the presses makes shells or cartridges and covers of refractory bitumen — the first component; the second part of the presses is preparing liners - the second component; A third of the presses are packed in cartridges and tightly closed with a lid.

The design of the presses is generally not beyond the limits of the existing ones used for the manufacture of plastics, etc., and in any case does not require large changes.

To be able to adjust the temperature during pressing, if required, the dies or molds may have an internal cavity for introducing steam or water.

From the bitumen press room, they are sent for labeling, storage and loading as dry cargo. When oil refineries n6 are in operation, the existing standard is the manufacture of bitumen with an output of 1, 2, 3, 4, which corresponds to penetration: 1Sh-200, 90-120, 40-70, Yu-30 and provided that the fourth grade bitumen meets carriage

in bulk, the plant can produce the following bitumen compositions: for a fourth grade, a single component composition; for a third brand, a composition of two components that make up a proportion in the mixture, as found by experience of approximately 15% of the fourth kit and 85% of the first brand; for the second mark, the composition of the same components in the proportion of 35% of the fourth mark and 65% of the first mark.

To manufacture the first mark, a composition will be required that goes beyond the established standard of the marks and therefore it is necessary to create a combination of a component that is more fusible than the first mark, the intermediate mark component and the fourth mark component (container).

In this way, a large number of combinations can be made and a corresponding number of product varieties can be developed, maintaining certain conditions of only one component, which in this case serves as a shell meeting the requirements imposed on Tspe.

An example of the technological process, which is given here for the production of petroleum bitumen, of course, does not exhaust all the ways in which work can be carried out to obtain the proposed product of bitumen plants.

For example, in addition to pressing, "Methods for pouring into molds, rollings, etc."

The subject matter of the invention.

A method of transporting bitumen, characterized in that high-melting bitumen, with or without a filler, is cast or pressed in the form of a container and filled with low-melting bitumen in order to save the container and to obtain the finished mixture.
