EADIEMAC Process
Preamble Used lubricating oil can be thermally cracked into lighter
#2 diesel or Marine Gas Oil (MGO)/Marine Diesel Oil
(MDO) products. This is a complex problem that is
difficult to achieve in relatively small refinery type plants.
The EADIEMAC Process is a mini-refinery designed to
efficiently deliver diesel products. The process uses well
established visbreaking technology to thermally crack used
lube oil into saleable products. The impurities from the
used oil are concentrated into a tarry waste material.

EADIEMAC Process
Introduction Thermally cracks used lubricating oil using
established visbreaking technology
Delivers a range of diesel products for off-road vehicles or marine fuel use
A mini-refinery with low capital & operating costs
A site for a 150 – 200 bbl/day demonstration plant is required

Thermal Cracking (no
hydrogen, no coke)
No hydrogen thus low pressure operation - 50psi.
Hydrogen is not required to achieve the diesel product objectives
#2 diesel, Marine Gas Oil (MGO) or Marine Diesel Oil (MDO) – Fuel Gas & Tar
Simple system, low capital cost, ease of operation, minimal controls, low operating costs

“Indirect” thermal cracking
High temperature eutectic salt
Standard heater to melt salt
Uniform application of heat around used lube oil
in tubes of shell & tube exchangers
Known refinery type equipment operation

Project Estimates
We will provide a project estimate on a case
by case basis. All plants are custom
designed to meet your specific feedstock
volume and availability requirements.

Key Advantages - 1
Accurately control salt temperature
Uniform heat transfer through shell & tube exchangers
Slowly raise temperature to achieve the degree of visbreaking required
A higher bulk temperature can be used thus producing greater quantities of gas oil
Uniform film coefficient to avoid coking
Control oil pumping rate through tubes
Easily control level, time & temperature in soak vessel to adjust to changes in feedstock quality
15/06/2009 Eadie Oil Inc. 12
Key Advantages - 2
Low pressure distillation of feed in the annular compartment of soak vessel thus saving a flasher unit & utilizing energy from visbreaking action
Use of a soaker drum helps produce a stable residue product
Incorporates quench of vapours from cracking exchangers
No equipment internals in the high temperature flash zone
Delays quench of liquid effluent until it approaches the perimeter of the soak vessel
Good energy utilization
15/06/2009 Eadie Oil Inc. 13
Key Advantages - 3
Can incorporate dual high temperature
salt/used lube oil exchangers & switch to
avoid shutdowns for cleaning
Can incorporate dual liquid/vapour effluent
lines into soaker vessel with removable
stainless steel liners to avoid shutdowns &
ease of cleaning

Current objectives
To secure a site to locate a demonstration plant of 150 - 200 bbls/day (24,000 to 32,000 liters/day).
To obtain feedback from operators
To “Fine tune” mini-refinery design to reduce capital & operating costs
To provide a training location for plant operators
