Overview
Tenova Advanced Technologies (TAT) offers differentiated, project-specific process technologies based on decades of research, equipment design and project execution. Advanced solutions include solvent extraction (SX) and electrowinning (EW) for the mining and chemical industries, membrane circuits, in-house state-of-the-art R&D facilities, expertise in minerals beneficiation as well as phosphate processing from ore to purified phosphoric acid and salts. Tenova Advanced Technologies specializes in both innovative technology development and robust pocess equipment for solvent extraction. Our experience and expertise in all aspects of SX includes:
- Development of SX processes utilizing an in-house R&D center
- Detailed design, supply and construction of SX plants based on:
- TENOVA SETTLER™ (Proprietary Reverse Flow Mixer Settler)
- Tenova Pulsed Column (TPC)
- Tenova Turbulent Technologies (TT) Mixing System
Technical Data
The TENOVA SETTLER™ is a patented technology which enhances efficiency and provides many advantages compared to other settlers used in SX circuits.
- Higher process efficiency
- Lower capital cost (approx. 20% reduction)
- More compact layout
- Shorter construction time
- Total automatic control capability
- Higher flux rate
- Lower organic losses
- Operator friendly physical layout
- Ease of operation and maintenance
- Improved fire prevention and control features
Innovation
Tenova Turbulent Technologies Mixing System is a new mixing technology which enables significant reduction of entrainment levels without changing the process flow. It can be easily retrofitted to most existing mixer settlers or installed in new SX plants. Unique capabilities:
- Creates uniform dispersion in the mixing tank (avoiding formation of small droplets)
- Predictable and controlled drop size distribution as a function of the mixing regime, allowing process optimization
- Increase throughput while maintaining optimum mixing conditions
- Increased throughput with no increase in entrainments
The main advantage of this technology is the reduction of entrainment of expensive extractants, organic contamination in the product stream, aqueous contamination in the loaded organic stream, ecological impact of organics in the raffinate stream, operation and maintenance costs.
It further enables increased settling flux and eliminates the need for after-settlers.
TENOVA PULSED COLUMN KINETIC INTERNALS (TPC-KI)
New internals, TPC-KI, provide a solution for processes with slow kinetics and high feed phase ratios. The new type of internals has been the result of on-going in-house development work and provides enhanced mass transfer for applications where the system has slow kinetics and potential for back-mixing. The TPC-KI includes new contacting elements on the contours of the "disc and doughnut" plates and optimized spacing between the plates. The TPC-KI internals reduce back-mixing and increase column hold-up allowing improved mass transfer at the same flux.
