Description
UOP14-MKII Crystallisation Unit Didactic Equipment Vocational Education Equipment Fluid Mechanics Lab Equipment

DESCRIPTION
Crystallisation is a valuable process in chemical engineering where the precipitation of a dissolved salt in a liquid mixture is required. The UOP14-MKII demonstrates this process in the laboratory so that students may gain a thorough understanding of this industrial technique.
Meaningful experiments can be conducted within a typical laboratory period and students benefit from visual observation of the process.
The UOP14-MKII introduces students to the fundamentals of crystallisation using a solution cooling method. It is a benchtop unit with a clear crystallisation reactor, which enables visualisation of the crystallisation phenomena.
The equipment consists of a jacketed crystallisation vessel provided with temperature control and agitation.
The solution is heated by circulating hot water through the jacket from the hot water vessel in a closed-loop system and the solution is cooled by circulating cold water from mains water supply or a chiller.
At the end of the batch operation, the crystals and mother liquor are collected using the beaker supplied, filtered, washed and then dried in the oven. The dried crystals are then sieved using the set of sieves supplied to analyse the crystal size distribution.
A conductivity sensor is included, which enables crystallisation to be monitored.
Different cooling rates can be investigated by the application of different water flow rates. A needle valve and flow meter are provided to vary the water flow rate quickly and easily to enable investigation of different crystallisation conditions, such as fast and slow cooling rates.
The instruction manual included contains experiments, providing a thorough grounding in the operation of crystallisation systems in the context of unit operations for chemical engineering students.
The equipment is supplied complete with a USB computer interface and data logging software.
The system may also be used in a continuous mode when used with the  Crystallisation Unit UOP14-11 Continuous Feed Accessory.
