Description

Description

Chemical engineering refers especially to chemical reaction engineering. Indeed, chemical reaction, catalyzed or not, are at the heart of all industrial syntheses. Study of a chemical reaction, in a perfectly‐stirred reactor, permits the operator to understand the influence of the different parameters in the optimization of the chemical synthesis with a view to its industrialization.

Features:

Study and compare four continuous reactors from two different experiments:
- Monitoring the dispersion (NaCl) in water to determine the residence time
- The saponification of ethyl acetate by soda
Contains four different reactors with the same volume (0.8L):
- One perfectly stirred reactor
- A cascade of two perfectly stirred reactors
- One plug-flow reactor
- One tubular reactor
Hydrodynamic study of the reactors by the residence time distribution (RTD) method:
- Determine residence times
- Compare theoretical and experimental results
Determine the chemical conversion rate by conductivity measurement:
- Materials balance, reaction yield
- Compare the efficiency of the different reactors

Proposed Experiments:

Determine the residence time distribution (RTD):
- Inject a coloured tracer and monitor conductivity.
- Use the experimental conductivity = f (time) graphs to determine the residence time for each reactor.
- Compare the reactors.
Saponification of ethyl acetate with sodium hydroxide.
- Calibration of conductivity sensors for sodium hydroxide assay.
- Monitor the reaction conductivity and determine the sodium hydroxide conversion rate.

"I have worked with the AYVA team since they launched in 2008 to equip our Science and Engineering labs. They have consistently gone above and beyond to ensure that we were prepared to meet our curricular goals and deadlines. I have been impressed by the breadth and quality of the lines they represent. We have purchased both PASCO and TQ equipment to enhance our teaching labs."

"All of the students that have the opportunity to see the [Eridès] Refrigeration Trainer in operation and do their lab report based on readings really get a lot out of it. Interesting to note: Our refrigeration tech was fascinated by the unit. He is a very experienced technician, and he was simply amazed at seeing the thermodynamic cycle in action. Typically, refrigeration technicians follow pressure and temperature readings, and gauging from his reaction, they most times give little thought to the phase changes that take place inside the guts of the unit.'

"Out of all the data acquisition systems I'm aware of, nothing approaches the convenience of the PASCO 850 interface. Between the broad range of available sensors and the simplicity of starting data acquisition, a wide range of tasks that would be incredibly complicated otherwise can be automated in minutes ... We have dedicated computers and 850 interfaces at each station in our labs so that data acquisition can be accomplished easily by our students whenever needed."

Gideon Humphrey
University of Toronto

"I’m often running two lab sessions at one time in two different rooms. Being able to use the base module like TecQuipment's Hydraulic Bench and quickly be able to switch out the experimental modules makes running a tight schedule of laboratory sessions possible. With a few of my own modifications like adding quick connects and valves I can make this changeover even slicker. The AVYA experience is great! Their post-sale technical support is unparalleled."

Dean Milton,
University of Regina

"AYVA has provided us with excellent support in getting training equipment that will enhance our chemical engineering labs. We have had the opportunity to work with their knowledgeable staff as well as representatives from TecQuipment and PIGNAT. We especially appreciated Sean McLaughlin, Technical Services Manager’s time and expertise when we purchased the H83 from TecQuipment. He was extremely responsive and resourceful during the on-site installation."

"We appreciate Pignat's willingness to partner with the university to customize a pilot training system that fits both our needs - and our budget. I want to thank AYVA for arranging a visit to Pignat's factory in France so I could meet the design engineers and see first-hand the attention to detail at every step of the manufacturing process. I especially want to thank my hosts at Pignat for their hospitality during my stay in Lyon. I really had a good time testing our CO2 absorption/stripping unit and seeing all the nice equipment in the plant."

Dr. John Zhang
University of Waterloo

"I am a long-time user of TecQuipment products - in particular the Modular Structures Range as well as other Materials Testing equipment. I find the modules (over 10) very easy to set up and, more importantly, my students find them extremely easy to use as they move from station to station conducting a wide variety of measurements related to structures and materials. Each experiment can be completed in 30 to 45 minutes and I can accommodate several students working in groups of three. It is a great addition to both my Basic Structures and Hyperstatic Structures courses."

"I have worked with the AYVA team to upgrade my Mechanical Engineering lab. We have not only been provided with excellent pre-sale service but we also received valuable support after we placed our order. We were provided access to a number of resources which we were able to use to develop our own customized labs for the students. The structures equipment from TecQuipment is being used to teach student groups in several courses at the undergraduate level. There is minimal setup required and students are easily able to switch between experiments. The excellent quality of the TQ manuals has enabled us to design our labs with relative ease. The equipment was delivered on schedule and the AYVA team has been very diligent in following up and providing us with the resources we need in a timely fashion."

Dr. H.J. Kwon
University of Waterloo

"Our mechanical engineering department recently wanted to upgrade our Gas Dynamics Laboratory in conjunction with our newly added aerospace program. After extensive research, we decided to purchase the AF27 Nozzle Flow Apparatus and the AF300 Intermittent Supersonic Wind Tunnel from TecQuipment with all the accessories including the VDAS Data Acquisition System. We are happy to report our investment has been well worth it. A perfect fit for our undergraduate laboratory. Students are raving how “cool” the units are and the relative ease to obtain accurate data. The laboratory size supersonic wind tunnel has been a big hit. At Mach 1.8, viewing the shock waves and expansion fans on an airfoil using the included Schlieren Apparatus has never been easier and more clear. The people at AYVA were amazing in helping us install the equipment. They answered all our question in a timely manner and delivered on time. The equipment is very well designed and built to last for a long time."

Peter Sakaris,
Concordia University

"We have recently acquired six KUKA robots for our Controls and Robotics Lab at the University of Toronto. Not only we are very impressed with the quality and performance of the units, but we are also very pleased with the level of service and professionalism we encountered from AYVA. They have provided a continuous channel through which we could interface with KUKA and fulfill our technical demands from the time of procurement, through to installation, training of personnel and commissioning. It has been a textbook case on how to support laboratory work in higher education."
