Experience and stability since 1919…

Over the years LE GAZ INTEGRAL, founded in 1919, has accumulated and developed an expertise and know-how in engineering and management of large projects. This is due to its involvement in the development of the gas industry all over the world and its countless successfully executed projects. 

This experience began on the eve of the 20th century with the study and construction of multiple coal gasification plants, oil products steam reforming units and associated gas treatments.

The resulting know-how acquired in traditional gas disciplines very quickly enabled LGI to successfully extend it business to oil and petrochemical industries, and more generally in the fields of energy and the environment.

Process management, the controlling of projects and construction of industrial units, often supplied on a turnkey basis, are the essence of LGI’s activity. Turnkey role and successfully conducted project management of many large projects are just as important towards contributing to the reinforcement of the company’s global strategy.

LE GAZ INTEGRAL has been significantly involved in the industrialization, development and implementation of innovative technologies for many decades. These are then used for the treatment of effluents and wastes, as well as for the development of natural resources.

Moreover, the company has tried throughout its history to adapt itself to the requirements related to the extent and the increasing complexity of the projects. This was accomplished through the implementation of the field standards and specifications, with the creation of its own referencial where necessary, whilst also scrupulously respecting quality, safety and environment issues.
