Propylene Recovery
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 was
contacted to evaluate the need.
Aggreko's solution
Within 24 hours of the equipment
arriving on-site the project was on-line meeting all process
objectives. Aggreko 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.
