It is the elimination of secondary entrainment from the structural elements of the separator that makes the SGV-7 so effective.

At the same time, the number 7 means the seventh generation of vortex separators. Generation 7 has absorbed all the advantages of the separator evolution process and allows us to claim the highest efficiency of the separator design, which ensures minimal liquid carryover from the device.

It turns out to be a paradox: in order for the separator to work more efficiently and separate particles with the smallest dimensions, its radius must be smaller.

As a result, we found the golden mean in this dependence and therefore the SGV-7 separators we produce have, on average, a housing diameter that is 2-3 times smaller than the housing diameter of, for example, a typical gravity separator.

This design layout allows for the separation of virtually all contaminants from the gas flow at the first stage of purification, and only a small amount of contaminants enters the second stage of purification (filtration stage).

As a result, not only the efficiency of the filters at the filtration stage increases, but also their service life. In this way, we managed to achieve a significant increase in the service life of the filter elements, in some cases it reaches three years without replacing the filters.

In addition, this arrangement leads to a significant reduction in the pressure drop across the device as the filter elements become clogged with contaminants.

Therefore, the two-stage arrangement of internal separation elements allows not only to qualitatively clean the gas flow from inclusions, but also to save space for construction due to the fact that, in fact, 2 devices with different functional purposes are installed in one housing.

In technology, two types of filters are most often used: coagulators and coalescers (and their combinations). As is known, coagulation is the process of adhesion and enlargement of mechanical particles of any solid substance, and coalescence is the unification and enlargement of drops. Filters, coagulators and coalescers are named after these two physical and chemical processes.
Roughly speaking, coagulator filters are filters that trap mechanical impurities, everything is simple and clear here, but with coalescer filters everything is much more interesting. A coagulator filter is an air filter for an internal combustion engine. A filter-coalescer is a filter at the outlet of a screw compressor that traps oil droplets so that they do not enter the compressed air line.

As you can easily guess from the name, each of them is intended for its own function, but there is a nuance. A filter-coalescer can work as a coagulator, but a filter-coagulator cannot work as a coalescer. This feature appears due to the fact that different materials are used for the tasks being solved. In coagulators (for gas or air), this is most often a paper-based material, and it is destroyed by liquid. And in coalescers, this is a fiberglass-based material with a given structure and cell size, it is not afraid of moisture and, due to its porosity, acts as a coagulator for mechanical particles.

But if coalescer filters are used as coagulators, they will not perform their main function, since they will quickly become clogged with mechanical and impurities.

As a consequence, their internal design has low efficiency due to the fact that the level of technology at that time did not allow the production of effective separators for a number of reasons.

Today, such devices have a significant operating time, but due to their satisfactory technical condition, they continue to be used at gas facilities, since their service life is periodically extended. The thickness of the device body wall allows them to continue to be used further, this situation will last for many more years.

However, the efficiency of gas purification in such separators is extremely low, which leads not only to a deterioration in the quality of gas preparation, but also to the possible failure of individual units, devices and mechanisms.

Our specialists have developed a method that allows us to solve this problem by replacing internal separation devices directly at the place where the separator is installed without damaging the integrity of the vessel body.

Repairs are carried out through existing manholes, and the dimensions of the SGV-7 separators allow for this work to be carried out.

This method of repairing and upgrading separators has found wide application, since it allows for a significant improvement in the quality of gas purification and an extension of the service life of separators already in operation.

The cost of carrying out such modernization is significantly lower than purchasing a new separator. In addition, the work does not require redesigning the facility's piping.

After approval, the assembly kit of internal separation devices is manufactured.

The customer prepares the device for the work on his own.

After the preparation of the device, the internal devices are replaced by the contractor or by the customer under the supervision of our specialists, depending on the agreement.

After the work is completed, our specialists develop documents to amend the passport of the vessel operating under pressure. These changes are agreed upon with a specialized organization.

After approval, the device can be put into operation.

In the gas industry, two dew point temperatures are distinguished in gas, for water and for hydrocarbons, since they have different physical properties.

The process of removing dissolved liquid from a gas is related to mass transfer processes and must occur at the molecular level, when the molecules of one substance interact with the molecules of another substance, affecting them. Mass transfer devices (absorbers or adsorbers) have a special design that allows gas to pass through a layer of absorbent or adsorbent, which results in the removal of dissolved liquid from the gas stream.

The separators have a conventional inertial design with metal structural elements. There are no mass exchange processes in them and it is not possible to lower the dew point temperature. In separators, only gas is purified from liquid, which is in the liquid state of aggregation, which is why the separation process is possible, since the liquid is separated from the gas by the action of centrifugal forces, inertial forces or gravity.

Even in coalescing filter elements, mass exchange processes do not occur due to the design features, since coalescence is the process of liquid droplets sticking together into larger formations. Therefore, gas drying is also not possible in coalescers, only cleaning.

The unit is placed on a mobile chassis, on a trailer or as part of a mobile chassis, for example, on a Kamaz chassis. This ensures the necessary mobility and speed of preparing the unit for work. The average time required to prepare the unit for work is 1-2 hours, depending on the qualifications of the personnel.

This reduces the time for preparatory operations, which has a positive effect on the cost of work at the facility.

The equipment set of the installation contains a gas separator SGV-7, which allows for the effective separation of liquid and mechanical impurities from gas coming from the well as part of the formation fluid.

Thus, the separated gas and liquid (a mixture of water and gas condensate) can be measured each in a separate flow, which significantly increases the measurement accuracy.

The automation system included in the equipment kit allows recording measurements of the main parameters of the well operation in all research modes.

Next, the collected gas is passed through a special measuring laboratory unit, where the liquid droplets are separated in a separator with a filter element that has a separation efficiency of 100%.

Thus, the selected gas sample shows the amount of liquid contained in the gas flow. Then, having the volumetric gas flow through the laboratory setup, the liquid content in the gas is recalculated to the volume of gas passing through the separator and thus the amount of liquid in the gas flow at the inlet to the separator and at the outlet from the separator is calculated.

There are 2 methods for assessing the quality of separator operation. The first one assesses the quality of gas cleaning in % of liquid content at the outlet of the separator in relation to the amount of liquid at the inlet of the separator. This method is incorrect, since at the outlet of the separator, as a rule, the amount of liquid carryover is constant, and at the inlet it can change depending on the technological parameters of operation. Therefore, the efficiency of separation by this method will differ depending on the amount of liquid at the inlet.

There is a second method, more correct, which we use. We evaluate the separation efficiency by the amount of liquid carried away from the separator in mg/Nm3, since this is the most accurate method and it does not depend on the input parameters of the separator.

Before starting work to determine the efficiency of the separator, the method by which the entrainment of liquid droplets will be measured and the method for assessing the efficiency of the separator are agreed upon with the Customer.

For example, extraction of plant materials occurs at a boiling point of the extractant of about 34 degrees Celsius.

This extraction technology allows not only to preserve all the useful substances (vitamins, proteins, polysaccharides, microelements, etc.) in the extract, but also to carefully transfer them from the raw material to the final extract. In addition, at low temperatures, there is no degradation of vitamins and proteins with polysaccharides, which prevents the appearance of breakdown products of substances and, as a consequence, harmful compounds in the final extract.

The vacuum extraction equipment we produce allows us to obtain a product that is not only competitive on the market, but also sets quality standards for the content of useful substances and compounds in the extract.

The capture of alcohol vapors and volatile components is carried out in low-temperature refrigerators, at a temperature of minus 42 degrees Celsius, which allows for the capture of almost all volatile components and their condensation for further use as aromatic fractions in non-alcoholic wine.

This technology of wine dealcoholization allows not only to obtain wine material without alcohol, but also to preserve all the organoleptic properties of the original wine, including aroma, color, and others.

Our technology is protected by a patent for invention and can be adapted to the needs, existing equipment and production traditions of the customer at his winery.

At the same time, you still have your usual split system with its own control panel and standard installation. Of the additional equipment, only a storage tank is added, which has the shape of a standard electric boiler.

To optimize installation costs, you can re-equip your existing split system for such installation, which will reduce the costs of installation and assembly of the system.
