"ALVIGO" is an association of design and technology companies from Estonia and Ukraine. It offers a new integrated concept of customer service in the field of engineering services. The activities of the subsidiaries included in "ALVIGO" JSC, such as LLC "Khimtekhnologiya" and LLC STC "ALVIGO", are primarily focused on the chemical and petrochemical industries. We have over 85 years of experience and knowledge in designing new and upgrading existing production facilities for mineral fertilizers, organic and inorganic chemicals.

ALVIGO JSC manages projects related to technology licensing, design, and scientific research developments in the chemical, petrochemical, and gas processing industries.

LLC "Khimtekhnologiya" is one of the leading research and design organizations in the field of chemical technologies, design, and construction of chemical industry facilities. It traces its history back to 1950 when the Lysychansk branch of the State Scientific Research and Design Institute of Nitrogen Industry and Organic Synthesis Products (GIAP) was established. In 2008, the "Scientific and Design Institute of Chemical Technologies 'Khimtekhnologiya'" was founded. Today, LLC "Khimtekhnologiya" employs highly qualified engineers engaged in the development of technological, basic, and detailed design projects, including new developments and improvements of existing technological processes. LLC "Khimtekhnologiya" is a comprehensive scientific and design institute whose tasks include the development of modern technologies for the production of ammonia, methanol, nitric and adipic acids, and acetylene, as well as their design and technical support for commissioning these production facilities. Today, the institute maintains its leadership status in the field of chemical technologies, which allows it to comprehensively improve technological processes. In recent years, significant contributions have been made to acetylene production technology—a key raw material for producing essential chemical products, including biodegradable plastics.

The Scientific and Technical Center "ALVIGO" was established in June 2002. It provides engineering services for conducting technological audits of ammonia and methanol production units, with the goal of developing technological solutions to improve the technical and economic performance of these production facilities. The center also provides consulting services during the preparation and execution of repair and commissioning work, including the reloading of catalysts in ammonia and methanol production units.
