Petrochemical industry

The heart of Exa International engineering activities is the production of hydrogen for the synthesis of ammonia, methanol and monomers. In 1992 after careful studies, the firm decided to specialize in this sector and to propose a turn – key service for the revamping of primary reformers and pyrolysis furnaces. From its bases in France, Houston and Moscow, the Group launched the new activity with immediate success. The first revamping was successfully achieved in Novgorod, Russia, and several others followed very quickly.

The strategic decision of producers to couple methanol to ammonia in several plants gave to Exa International the opportunity to enlarge its services to the revamping of reformers for methanol production. This development was a success.

Through vertical integration, the firm established a series of steps to guarantee to her clients a steady supply of all high quality items entering in the process of repairs such as insulation, cracking tubes, pigtails, spring supports, for the radiant zone of the primary reformers and heat-exchangers for the convection zone. Through additional studies major technical steps were carried out to improve the quality/price ratio and the lifespan of the equipment.

After careful studies, Exa International went one step further into the integration of its technical offer. A test production of cracking/reforming tubes and prefabricated primary reforming furnaces began in 2003 in Togliatti, Russia. After the successful delivery of several prefabricated furnaces, the test site has been extended into a world class centrifugal foundry with a capacity equivalent to most existing world class plant (7 centrifugal casting mills).

Exa International entered the air separation industry in 2002 with the successful delivery of a CO2 recovery unit, then extended its expertise to Nitrogen Oxygen and Argon units.

In February 2010, Exa International became the exclusive dealer on the Russian and CIS territory of the British centrifugal tubes and fittings manufacturer, Cronite Scomark Engineering Ltd. and took the opportunity to develop its activities in the olefins (ethylene) production.
