BD 55
BD 55 is a small sized member of the biodiesel separation system family. It is available in two different Ex-executions; inerted for separation of flammable liquids and electrically protected for separation of non-flammable liquids.
Product Description
Applications
The BD 55 is specially designed for use in the production of biodiesel and is particularly suitable in the following applications:
- Separation of glycerol from methylesters after esterification
and transesterification reactions - Washing of methylesters
- Purification of glycerol
Special features of the centrifuge
The hermetic inlet ensures gentle acceleration of shear-sensitive agglomerates and particles and also prevents emulsification. Combined with a new patented disc stack design, these significant improvements of the fluid dynamics lead to maximum separation efficiency, and reduce power consumption at the same time.
The discharge volume is adjustable, thereby preventing any risk of liquid seal breakage. The system is modularized and designed for one floor installation. A specially designed variable frequency drive (VFD) system provides low starting current. The built-in paring discs for the liquid phases eliminate the need for external pumps. The bottom part and top part are gastight and suitable for blanketing at a low inert gas consumption.
Standard design
The BD 55 separation system consists of a self-cleaning disc stack centrifuge and all the auxiliary equipment needed for a safe, efficient operation. This includes:
- Process and service liquid module, comprising valves, fittings and instruments for process and service liquids entering and leaving the centrifuge. All product-wetted parts are made in high-grade stainless steel. Liquid-wetted rubber gaskets are made in Viton rubber. The components are premounted on a stainless steel frame.
- Set of connection fittings.
- Starting equipment for VFD drive of the centrifuge motor, also including a transformer for power distribution to other electric components in the system. For installation in non-hazardous area.
- Control equipment, including a PLC, type Siemens, pre-programmed to control and supervise the separation system. For installation in non-hazardous area.
- Operator´s control panel for local operation of the separation system. For installation in hazardous area.
- Pneumatic unit, comprising a cabinet with pressure switch, pressure reducing valve and solenoid valves, for instrument air supply to the separation system. For installation in hazardous area.
- The centrifuge is equipped with sensors for monitoring bowl speed and vibration level.
