Biodiesel Process Trainer PLC Controls provides students the opportunity to gain real operating experience focusing on all aspects of biodiesel production the chemical process, control strategy, and management of the chemical process. The Biodiesel Process Trainer is a pilot-scale plant that demonstrates both batch and semi-continuous conversion of vegetable oil feedstock into biodiesel. The Biodiesel Process Trainer has instrumentation to provide for control of all process flows, temperatures and levels.
Function:
The rate of reaction is influenced by several factors including temperature and degree of mixing. The Biodiesel Process Trainer is designed and built for instructional use and includes many student-friendly features. The conversion of triglycerides into biodiesel is normally performed by base-catalyzed conversion. This reaction takes place at modest conditions of temperature and pressure and can produce conversion rates over 98%. This highly flexible process trainer incorporates various commercially available mixing technologies and process configuration options to allow for the comparative analysis of the technologies currently available in the biodiesel industry. The main reaction vessel is constructed from industrial glass allowing the students to visually monitor the trans-esterification process.
The simple heating circuit with one subcircuit contains two flat radiators and is controlled by a temperature-led controller. A three-way mixing valve is the actuator. A complete domestic heating system can be set up using the trainer together with a hot water generator, Hot water passes through the radiators and heats the room air. It contains two heating circuits. A simulator is supplied for varying the outside temperature. The heating circuit with two subcircuits contains four radiators and two heating controllers. Both heating circuits are equipped with commercially available heating technology control devices. Solenoid valves enable control of the heat distribution in the two subcircuits. Each heating circuit contains a circulating pump.

The unit provides students with the opportunity of investigating the effects of a change of controller parameters (proportional band, integral and derivative times) on the control capability of the system. The Temperature Control Apparatus illustrates the control of temperature in a simulated reactor vessel by controlling the supply of coolant (air) in response to changes in process conditions. The unit is made up of typical items of control equipment currently used in industrial applications, thereby providing an excellent opportunity for familiarisation.

A dye injection system is provided which allows for a single filament of dye to be introduced into the entrance to the convergent section to enable laminar and turbulent flow regimes to be demonstrated. Bernoulli's Apparatus consists essentially of a two dimensional rectangular section convergent divergent duct designed to fit between Constant Head Inlet Tank and Variable Head Outlet Tank. The convergent divergent duct is symmetrical about the centre line with a flat horizontal upper surface into which the eleven static pressure tappings are drilled. The differential head across the test section can be varied from zero up to a maximum of 450 mm. The test section is manufactured from acrylic sheet. The height of the channel at entry and exit is 19.525 mm and the height at the throat is 6.35 mm. The static tappings are at a pitch of 25 mm distributed about the centre and therefore about the throat. The lower surface is at an angle of 4 29'. The width of the channel is 6.35 mm.
