Electrochemical protection of the bottom of the ship.

Small magnesium-zinc protectors welded in the bow and stern will protect the huge hull from destruction for a long time.

Stainless steel smelting.

The widespread use of such steel is hindered by its high cost and complexity of processing.

Kuibyshev Synthetic Rubber Plant.

Here, at one of the production stages, sulfuric acid was used as a catalyst, which caused severe corrosion of the metal.

Due to corrosion, very expensive equipment had to be changed 10-15 times during the year.

As a result, the cost of synthetic rubber increased significantly.

Employees of the Leningrad Research Institute of Petrochemical Processes proposed a solution.

Laboratory of the Institute.

They suggested using another catalyst with reduced corrosion activity.

Testing of samples.

Comparison of metal parts before and after exposure to the catalyst.

Plant equipment.

Remote control of production processes.

The new reactor has been operating smoothly for a year and a half.

Filming inside the reactor.

Steel does not deform.

Repeated comparison of metal parts before exposure to the catalyst and after under new working conditions.

Switching to domestic reactors will result in significant savings in money.

Artificial rubber packaging line.

The use of a new catalyst made it possible to conduct the production process in a closed cycle.

Computing on a computer.

Plant equipment.

Treatment facilities of the Kuibyshev Synthetic Rubber Plant.

Previously, the plant dumped about 18 thousand tons of biologically difficult to decompose products into the Volga.

After changing the technological process, the discharge of organic matter into the Volga near Togliatti decreased by 80%.

Other large factories are also switching to this technology.
