Pilot Scale Hot Oil Systems

Pilot Scale Hot Oil Systems

Pilot Scale Hot Oil Systems

(OP)
Greetings,

I need to purchase a small hot oil system for a pilot plant.  Something on the order of 25 KW max and oil temperature in the neighborhood of 500 F.  I am not familiar with these systems.  Looking for some recommendations for a good reliable skid mounted self contained unit with pump and temperature control.

Anyone have experience with this?

Thanks in advance.

RE: Pilot Scale Hot Oil Systems

Do you have a geographical region within which you'd like to source this equipment?

I don't know what succes you've had with an internet search but rightly or wrongly, and lacking any specialist supplier data, I would start by looking at the companies who supply fuel oil heaters to the marine and power industries. These companies routininely design and supply fuel oil heater systems including all pumps, sensors and controls.

For example, you might try ELWA in Munich for electric oil heaters. They will design and supply a package including pumps, temperature sensors, control electronics etc.
Other such suppliers could be MAS (Germany)for steam or electric heater systems.

RE: Pilot Scale Hot Oil Systems

Joechem,

The unit could be self designed rather than procured as a skid.  Essentially the system will include pumps, a heater, an expansion vessel and control\trip instrumentation.  All of the components should be able to be bought of the shelf.  Self design allows much greater flexibility, particulalry with regard to layout/space allocation.

The system should be arranged so that the expansion vessel is located at the high point of the system feeding the circulation pumps.  The pumps will pump cold heating medium through the heater to the load (heat exchanger or vessel jacket) and back to the expansion vessel.  Demand at the load should be controled by a simple temperature control loop.  Any demand not taken up by the load should be recirculated back to the expansion vessel using a minimum flow bypass, i.e. even if the demand at the load is low the pumps will still be able to deliver a flow which prevents them from overheating.  I'd recommend an electric heater.  The expansion vessel could be open to atmosphere or pressurised with compressed air if there is a risk that the heating medium could boil at atmospheric pressure.

I would get in touch with  companies such as the following who have  experience handling thermal heating fluids.  I’m familiar with the following.

 Or if you go the do it your self approach here is a lot of information on Therminol.

Here is a list of equipment manufacturers of thermal heating fluid.

JoeChem:  by your use of Fahrenheit I would guess you're in the US.  Have a look at Gaumer Process Heaters, CCI Thermal etc.  They can provide you a heater or an engineered skid package.  At 25 kW you should definitely be looking for an electric unit.  Designing such a system yourself is no big deal if you're a chem eng, and there are lots of people out there who can build one for you.

RE: Pilot Scale Hot Oil Systems

One thing you need to lookout for is that you are at or near the boiling point of most high temperature thermal fluids.  I definitely would seek assistance of your supplier in the design and not depend solely on hydraulics.
