The challenge to the customer
A Midwest olefins producer was experiencing limitations in the
recovery section of their propylene unit. This was not only
affecting production but was also causing unwanted flaring of the
propylene. A fouled heat exchanger was believed to be the problem
and a plant outage would be required to clean the exchanger. This
would require several days of lost production which the plant could
not afford to take.
Aggreko Process Services was contacted to evaluate the need. A
meeting was held at the customer’s site and
Within 24 hours of the equipment arriving on-site the project
was on-line meeting all process objectives. APS reviewed the
options available and recommended a solution that would meet the
customer’s needs and was least intrusive to the plant for
installation avoiding an unscheduled shutdown.
The benefits to the customer
The project has allowed the plant to maintain production until a
scheduled shut-down of the unit could be coordinated. In addition,
the plant has no longer been required to flare the propylene
avoiding potential environmental penalties.
