Scientists from Kazan Federal University, together with colleagues from the Nikolaev Institute of Inorganic Chemistry of the Siberian Branch of the Russian Academy of Sciences and Gubkin University, have created the first installation in the country for the rapid production and pressing of gas hydrates. This was reported by the press service of the Ministry of Education and Science of the Russian Federation.
The use of [the installation] will allow obtaining and testing pellets that can become a commercial form of "solid gas" technology for its storage and transportation.
The created device combines two technological processes: the formation of hydrates and their transformation into pellets, which are convenient to store and transport. For this, gas is directed into a reactor filled with an aqueous solution with special additives that accelerate the formation of hydrates. Then the hydrates are pressed using a mechanism similar to a piston, which is driven by a hydraulic pump.
The idea of creating hydrates in laboratory conditions is not new. However, existing analogues developed in other countries cannot effectively solve this problem and have complex technical equipment.
Scientists from Kazan Federal University have improved this technology. The Russian installation significantly simplifies the design and reduces the time required to obtain hydrate.
Earlier in Novosibirsk, a composite building material was created from recycled plastic bottles. A special cutting mill was used for grinding, and the selected plastic fractions were compressed. The resulting material was tested for density, strength, thermal conductivity, and water absorption. The research results confirmed that it is suitable for use in wall cladding.
