Drul participates in the installation of the largest steam turbine in the world.

In December 2021, the Cerradão plant acquired the largest backpressure steam turbine and the largest four-pole generator in the world sugar-energy sector from the WEG group. The plant, which has been in existence since 2008, generated 84 megawatts per hour (MW/h) of energy with an installed capacity of 105 MW/h, enough to supply a city of 230,000 inhabitants. After the acquisition, which in addition to the 60 megawatt (MW) backpressure BT steam turbine and the four 13,800 volt (V) poles of 1,800 revolutions per minute (rpm) and 60 hertz (Hz), also included a reducer SuperTurbo, a 66.7 megavoltampere (MVA) ST generator, and a complete protection, control and supervision system, with cubicles, panels, battery system and chargers, increased its energy production capacity to 165MW/h.

Due to its extraordinary dimensions, this grandiose project would not have succeeded without a powerful water supply system capable of meeting its operating requirements. That’s the role of reverse osmosis, a process that doesn’t require heating, and that has more advantages over other options, such as less problems with corrosion, lower energy requirements, removal of unwanted contaminants (such as trihalo- methane, pesticides and bacteria), occupies less surface area than distillation facilities, reduces up to 99% of total solids and therefore ensures high purity water.

Due to the magnitude of the undertaking, the development, installation and operation of the reverse osmosis system at the Cerradão plant required the establishment of a partnership with a company that mastered the technology and possessed the know-how.

Paulo Mangolini, technical director at Drul.

Com experiência as áreas industriais e processuais, o dimensionamento e projeto contou com o Engenheiro Paulo Roberto Mangolini, Diretor Técnico do Grupo Drul, e renomado profissional no ramo de equipamentos e tratamento de efluentes.

Assim, em dezembro de 2021, a Drul, um grupo com foco em inovação tecnológica soluções eficazes e lucrativas, realizou um feito histórico: fechou a venda de equipamentos para todo o complexo de tratamento de água para geração de vapor e energia. Este feito fez da Drul a empresa responsável pelo fornecimento de água do maior projeto de cogeração de energia do mundo, dentro do setor sucroenergético, frente a frente as principais multinacionais do setor de tratamento de água. Trabalhando com o que têm de melhor em tecnologia  para esta finalidade, implantando um conjunto compostos por um filtro multimídia, utilizando leito de filtração via zeólitas classificadas, um banco de OR utilizando membranas Nitto Hydranautics CPA5LD, bombas de recalque centrifugas verticais múltiplo estágio modelo Wilo e um vaso de polimento para permeado (desmi) operando com resinas sintéticas de troca iônica e catiônica suficientes para entregar 85m³/h com qualidade assegurada por normas técnicas para atender reposição de água de alimentação de um parque de caldeiras de alta pressão com capacidade para produzir até 800TVH.
