Bitumen packaging. Petroleum bitumen

The main results of the research are: cost-effective involvement in the development of fields in new gas producing regions (water areas of the Ob and Taz Bays, the Yamal Peninsula, the shelf of the Barents and Kara Seas, Eastern Siberia and Far East), as well as the creation of technologies for the effective development of small gas fields and unconventional resources, such as coalbed methane.

OJSC Gazprom pays great attention to the development and use of Russian high-tech innovations. In particular, one of the company’s priorities when implementing new projects for the production of liquefied natural gas(LNG) is an increase in the Russian component in terms of the use of domestic equipment.

Development own technology Gas liquefaction will eliminate Gazprom’s dependence on foreign developments, and will also create the possibility of supplying Russian-made equipment to LNG plants.

For autonomous power supply of cathodic protection stations, communication systems and telemetry of main pipelines, the first demonstration model in Russia of a fundamentally new environmentally friendly power plant on fuel cells with a proton exchange membrane. Currently, work has been organized to master its serial production. The implementation of the installation will ensure a reduction in costs for the purchase of imported power plants with a capacity of 3-5 kW and thermoelectric generators, as well as a reduction in costs due to gas savings for own needs.

Recycling

Projects are being implemented to create a pilot plant for the production of synthetic liquid fuels with a capacity of 100 thousand tons per year, as well as a small-scale plant for the production of high-octane gasoline for use in low-yield and low-pressure wells.

For the rational development of helium-containing deposits, technologies are being developed for the integrated processing of raw materials with the production of LNG and the release of helium, as well as technologies and technical solutions on transportation and storage of helium. In order to increase the depth of processing of liquid hydrocarbon raw materials and improve the quality of produced motor fuels in accordance with Euro-4 and Euro-5 classes, secondary processes for processing stable gas condensate and oil are being introduced. In addition, the creation of technology for processing high-sulfur fuel oil at the Astrakhan gas processing plant using electron-stimulated cracking continues.

Gazprom is trying to improve quality highways in our country through the use of sulfur asphalt concrete in their construction and repair. Sulfur asphalt concrete is produced at the same plants as regular material for road surfaces. It contains about 2% modified sulfur, and this additive practically does not increase the cost of the material. At the same time, road surfaces using sulfur asphalt concrete do not require repair for 5-7 years.

Motor fuel

Gazprom also strives to solve one of the world's main problems - air pollution in large cities. It is no secret that the largest volume of harmful substances in megacities is emitted by cars that consume petroleum products. Converting them to compressed natural gas (CNG) dramatically reduces the level of these emissions. If we take Euro-4 gasoline as a standard, it turns out that in terms of nitrogen oxide emissions, CNG wins almost three times, in CH - 14 times, in benzopyrene - more than 16 times, in soot - three times (in comparison with diesel fuel - 100 times).

In 2010, the Gazprom Group opened four gas filling stations in Russia, one in Germany, one in the Czech Republic and a natural gas liquefaction complex at GDS-4 in Sverdlovsk region, and also began operating a gas filling station in Kuzbass, which uses coal bed methane. In addition, car conversion centers were opened in Saratov and Krasnoturinsk. Plans for 2011 include the construction of 21 more gas stations.

Like anyone else construction material, bitumen must be able to be delivered to remote construction sites. But you won'tequip smoking machines on all roads that prevent the bitumen from hardening. It’s better to bring it to the place and melt it there. This means that after receiving it, it must be packaged so that it arrives at the place of use uncontaminated.

Bitumen packaging

The packaging should not only protect the bitumen from dirt, it should provide a convenient form for transportation. After all, it is clear that a frozen bitumen clot of unknown size and shape will be difficult to bring to fruition at a construction site. Let's look at some packaging methods:

Marking of bitumen

It is needed for any building material: it is important to know what is in the package, you won’t open all the packages and achieve the desired result experimentally.

Alphanumeric marking: B - bitumen; N - oil; K - roofing; D - road; I - insulating; M - mastic; G - hot. Thus, the abbreviation BND will mean “petroleum road bitumen”, and MBK-G will mean “hot bitumen roofing mastic”.

For construction bitumen, the letters are followed by an improper fraction, for example, 70/30, where the softening temperature is in the numerator and the conditional hardness is in the denominator. The complete marking of construction bitumen may look like this - BN-90/10.

For road bitumen BND-60/90, the numbers mean something different: the numerator - denominator are the upper and lower limits of the change in penetration, that is, in what range the hardness can change with a change in temperature.

For roofing bitumen BNK-45/180, the numerator is equal to the softening temperature, the denominator is the average penetration value. For roofing mastic MBK-G-65, the numbers show the heat resistance temperature.

Transportation of bitumen

If transportation is carried out to a warehouse, or over very long distances, then it is transported to solid state, convenient for moving, loading and unloading. To transport bitumen to the construction site, we use bitumen trucks so that there are no problems with loading and so that it is immediately ready for use. After all, what is a concrete truck? A huge thermos with double walls and heating, mounted on a car. Thanks to bitumen trucks, time on construction sites is significantly saved.

More about bitumen:

Why do you need to fill bitumen into big bags? What are the advantages of this container? What equipment is needed for such packaging?

Bitumen is a traditional material in road and civil construction. It is used for waterproofing, repairing road surfaces, preparing asphalt concrete mixtures and so on. At the same time, to obtain a good result, every stage associated with bitumen is important: production, storage, transportation and technology of use. In this article we will dwell in more detail on the transportation of bitumen from the storage (production) site to the work site. Key role At the same time, the container plays.

Big bag

What is a big bag?

Bitumen can be packaged in metal euro-barrels, vat containers, bulk drums, big bags, etc. A big bag is a medium- or large-sized bag with loops for slinging. It is characterized by a load capacity of 25 to 1000 kg, but there are also models that successfully cope with weights of up to 3000 kg. Big bags consist of a polyethylene liner, which is placed in a polypropylene fabric shell.

Advantages of big bags as containers for transporting bitumen

• relatively low cost;
• compact size;
• temperature range from 100 ºС to 180 ºС;

Euro barrels

When performing repairs and construction work Based on bitumen, a number of problems arise, without a positive solution of which it is impossible to obtain a good result. In particular, it is necessary to ensure the transportation of material from bitumen storage facilities to places of further use. In practice, special tanks (for large volumes) and smaller containers - bags, barrels, etc. can be used. In the second case, you also need to solve the problem of packaging bitumen.

A Euro-barrel is a container made of metal. It can be used for both storage and transportation petroleum bitumen, as well as compositions based on them with a softening point not lower than 35 ºС. A standard euro barrel has a volume of 210 liters, a diameter of 585 millimeters and a height of 960 millimeters.

Distinctive features of Euro barrels

Let us list the main advantages that are typical for Euro-barrels as containers for bitumen:

• ease of loading and unloading;
• possibility of compact placement during multi-tier storage;
• due to the relatively low weight, it becomes possible to use various medium-tonnage equipment (truck cranes, trucks, etc.) for loading;
• ease of unpacking.

Barrels

Why do you need bitumen packaging equipment? Why is it better to keep bituminous materials in barrels? What are the benefits and advantages of this?

Application

Bitumen is an indispensable material for the repair and construction of highways. Thanks to properties such as hydrophobicity and increased adhesiveness, it performs the important function of binding layers of asphalt concrete mixtures. In addition, bitumen is successfully used for surface treatment of old road surfaces and priming of the road base before applying a fresh layer of asphalt concrete.

Transportation

One of the most problematic stages is transporting material from bitumen storage facilities to places of direct use. When using small volumes of bitumen, which are consumed without leaving any residue, the most acceptable option is the so-called non-returnable packaging: bags, boxes or barrels.

Barrels as containers for bitumen

Nowadays, metal barrels are widely used as containers for bitumen, due to the simplification of warehousing and storage processes. Packing the material into such barrels requires special equipment.

Brief description of the technological process

Bitumen is cooled on a cooling conveyor with a capacity of up to 4.2 t/h. If necessary, provide more high productivity, 2 or 3 cooling lines are installed in parallel. Using dosing devices made in the form of overflow baths, liquid bitumen is supplied to a steel belt, which is the main element of the cooling conveyor. The steel belt is equipped with four limiting strips, so that 3 strips of product with a width of about 400 mm and a layer thickness of approximately 10 mm are formed on the belt. Bitumen is supplied by dosing pumps. For each production line there is 1 dosing pump, i.e. for each cooling conveyor - 3 pieces, which have a joint drive with an adjustable gear.

To reduce the adhesion of bitumen to the steel strip, before feeding the bitumen, the strip is automatically lubricated with a release agent (3% soap solution, silicone oil, etc.). Thus, after hardening, the bitumen can be easily removed from the steel strip.

The heat generated during the bitumen cooling process is removed through the surface of the steel belt and absorbed by cooling water sprayed through nozzles onto it. inner surface. The high thermal conductivity of SANDVIK 1200SA tape (1.4310; AISI 301) ensures highly efficient heat dissipation. The design of the cooling conveyor is designed in such a way that the possibility of product contact with cooling water is completely eliminated. Cooling water is collected in trays built into the cooling conveyor, from where it enters a storage tank for subsequent cooling in the refrigeration unit.

The entire length of the cooling conveyor is closed with a sealed casing equipped with an exhaust fan.

The cooled bitumen strips are cut into sections of approx. 800 mm and then stacked on top of each other until a bitumen block of a given thickness is formed. The bitumen blocks then enter a transverse conveyor.

In the next step, the bitumen blocks are automatically wrapped in polyethylene shrink film and entered into a shrink chamber. The packaged blocks are then conveyed along a roller conveyor to the palletizing machine.

Thus, within 20-30 minutes from the moment of filing liquid bitumen The workshop is ready to ship a packaged pallet with bitumen blocks that meet the highest European standards in terms of packaging.
