…of a wide range of gaseous media

Various sectors of the economy have one common goal – the expansion of opportunities of the effective use in the wide variety of gas environments of the major industrial energy carriers. The idea of implementation in readiness of gas environments in short terms and without the use of high cost and energy intensive products and equipment becomes a reality and proves itself with the use of industrial equipment joint together with composite polymer materials. In the following example, we will demonstrate and analyse the ability and use of the composite polymer materials and equipment that is based on them, for ensuring proper supply amounts of gases and their cleanliness.

The goal of this testing is to increase the gas and purification processes, which include drying, removal of solids.

Object: The pressure of oven burner: 0.1 МРа, the volumetric flow rate: 1-5 m³/h (Fig.2).

The flame of the burner during the test was light blue color that indicates the absence of any impurities (Fig.2).

  • After six hours of operating, the cartridge resistance growth has not been noted. The detached turbid emulsion was poured into a transparent container (volume of 25 liters) of pale gray-yellow in color with a faint odor of petroleum product (Fig.3), which accounted for 17.3 – 20.8 grams per 1 cubic meter of gas.

  • After 15 hours of settling emulsion has changed color to light beige, it has become more transparent. Оn the surface of weak iridescent membrane formed, at the bottom of a precipitate in the form of fine solids dark brown in color, which were made with water droplets in settler filter housing of the cartridge body, which confirms the effect of partial self-regeneration has been observed previously [1,2].


After obtaining the effect of separating liquid drops in full volume, as evidenced by the color of the flame and equipment operations, it was decided to extend the test to determine working life of the «Cribrol» cartridge.

The installation was placed in front of a gas piston power station on the gas supply line from a borehole. Cartridge worked for 12 months, after which partially lost its effectiveness, as evidenced by outages equipment.

According to the results of the tests, systems for a number of FEC objects were developed and installed.


Along with the experiments on the hydrocarbon gas environment, it was conducted a series of experiments on the use of cartridges “Сribrol” on pneumatic systems in a variety of operating conditions, especially as bench tests were conducted earlier.

Driving line from the compressor to the consumer consists of:

«Compressor – filters rough and fine filter – dryer – receiver – pipeline – consumers»

We have proposed a modified scheme:

«Сompressor – filter “Cribrol” – the pipeline – the consumer – machine tools for the manufacturing blowout after metalwork»

To demonstrate the dynamics of the dehumidification filter “Cribrol” was installed together with the supply line to another machine with a standard filter.

The amount of fluid drained from the filter housing on the lines 1 and 2, were recorded by the foreman daily, prior staring his shift.

During the first stage of testing:
– In “Сribrol” filter body water was not observed (going process of saturation);
– A staff of the filter body was poured to 50-650 ml of water.

When the condensate drainage in the lines on the machine is made:
– On the line 1 with the cartridge “Сribrol” condensate was not observed;
– On the line 2 before the change systematically blended condensate in significant volumes.

The results of measurements of parameters “Сribrol” filter testing process in the compressed line for machine tools.

The absence of condensate and solids in the line after the filter «Cribrol» shows its effectiveness, which may increase the working resource for the pneumatic tools and equipment operating only with the participation of the compressed , including various motors, valves and pipes.

All of the technical characteristics shown above physically and visually show the universal use and effectiveness of “Cribrol” equipment performance, when utilized with composite polymer materials for the following treatments: cleansing, drying, removal of mechanical additives of different sizes, separation of and petroleum products in a wide variety of gas environments.
