Thyssenkrupp Industrial Solutions S.A.S. (Aix en Provence, France) was awarded a contract by Secil Group, a major Portuguese cement producer and provider of construction materials, for the modernization project of Secil’s Outão cement plant, one of the 3 cement plants operated by Secil in Portugal. These modifications will contribute to reducing the dependence on fossil fuels and promote the development of low-carbon clinker and cements.

The existing production line, established at the beginning of the 20th century, is located south of Lisbon on the peninsula of Setùbal. With an annual production capacity of around 2 million tons, it is one of the largest cement plants in Portugal. The Outão facility includes a private maritime quay that allows annual exports of almost 1,5 million tons of cement and clinker by sea to more than 20 countries.
SECIL implements the R&D Project “CCL – Clean Cement Line” at its Outão cement works in Portugal. The CCL Project, aims to bring the plant to the forefront of energy efficiency, low NOx and lowest CO2 emissions among the European cement producers. The CCL Project is partly funded by the Portugal 2020 Government incentives program.
Samir Abi Ramia, CEO of thyssenkrupp Industrial Solutions France: “This project marks a milestone for our Grey2Green initiative and is proof of the rising demand for green technologies in the cement industry. Secil is aware of the stakes of tomorrow and beyond and places great value on sustainability. With our energy-saving and emission reducing technologies we are proud to play our part in the transition towards a carbon neutral cement production.”
thyssenkrupp’s scope consists of the modification of the existing rotary kiln and preheater tower, which includes several new developments to provide a highly customized solution to SECIL. The installation of a new AS-MSC calciner equipped with a prepol® SC-S calcining system will increase fuel flexibility and maximize the use of a wide range of alternative fuels, with a minimum substitution rate of 85%. A new polytrack 7T/5-3R grate cooler, including a new cooler dedusting system, will replace the existing planetary cooler.
