The pilot program's primary aim was to demonstrate the enhanced efficiency of soap and fiber extraction from black liquor using Centrisys Renewables Decanter Centrifuge Technology (DCT) at a kraft pulp mill. Traditional black liquor soap skimmers are older technology and, in most cases, have not been upgraded in years. The DCT technology leverages a sophisticated three-phase decanter centrifuge, designed to optimize the separation processes and improve operational stability.
The DCT System incorporates a high-grade CS21-4HC 3-phase skid-mounted decanter centrifuge, forming part of a comprehensive skid assembly. This assembly is meticulously designed, featuring a separator, a valve module equipped with essential components for optimal routing, and an advanced electrical control panel that includes a 480 v breaker and a Programmable Logic Controller (PLC). The system is also equipped with specialized pumps for managing inlet and outlet flows, ensuring efficient process management.
Seamlessly integrated with the mill’s existing soap skimming processes, the DCT System enhances operational efficiency without disrupting ongoing operations.
To ensure reliability, performance samples were collected at regular intervals and analyzed using a dual-method approach in three distinct laboratories. The analytical results confirmed the high efficiency of the proprietary DCT System, highlighting its capability to:
Implementing the DCT technology offers several advantages:
The integration of Centrisys Renewables Decanter Centrifuge Technology (DCT) streamlines the recovery of black liquor soap and fiber and also aligns with sustainability goals of modern pulp & paper mills by enhancing efficiency and reducing waste. The DCT system is fully customizable and available in different sizes and metallurgies.
