Overcoming Seasonal Cooling Problems in
Distillation Column Overheads
Some of the most ubiquitous and, in our opinion, most serious problems confronting
operators are the results of seasonal or diurnal variations in ambient air and cooling
water temperatures. Generally, distillation column overhead cooling systems are designed
for some sort of average summertime cooling water or air temperature. These are
routinely exceeded, according to seasonal weather data, for extended periods during the
peak summer months. Also, over time, column throughputs have been increased as units
were debottlenecked or when other process changes were made. On occasion, purity
specifi cations may change, inexorably becoming more stringent.
We will show examples of how it is feasible to restore column overheads cooling
capacities to winter-like conditions by installing temporary, or seasonal, supplemental
cooling solutions. Also, we discuss some of these techniques that have been proven
successful in a large number of past applications in the petroleum refi ning, petrochemical,
and complex chemicals industries.
