PE0765 : MEG (Monoethylene Glycol) Manufacturing Process Technology

This practical and highly-interactive course
includes real-life case studies and exercises where
participants will be engaged in a series of
interactive small groups and class workshops.
Monoethylene Glycol (MEG) plays a significant role in
industry due to its function as versatile intermediates in
a wide range of applications—from polyester resin,
textiles and films, consumer packaging and beverage
bottles to aircraft deicing fluids. Monoethylene glycol
(MEG) is one of the most important raw materials for
industrial applications. MEG is important in the
production of antifreezes, coolants, aircraft anti-icer
and diecers and solvents. Moreover, MEG is often
used in water-basedpaints,dry-wall compounds, glass
cleaners, dyes, waxes and adhesives as well as a
freezing point depressor to avoid damage by lowtemperature
extremes.
Monoethylene glycol in its pure form is an odorless,
colorless, syrupy liquid with a sweet taste. In general
terms MEG is produced from ethylene, via the
intermediate ethylene oxide which it reacts with water
to produce ethylene glycol. The highest yields of
ethylene glycol occur at acidic or neutral pH with a
large excess of water. Under these conditions, MEG
yields of 90% can be achieved. The major by products
are the ethylene glycol oligomers diethylene glycol,
triethylene glycol and tetraethylene glycol. Due to its
importance and fast growing demands as a result of its
bulk uses and the availability of ethylene in GCC and
other petrochemical centers several innovative
technologies is developed and commercialized.
