High-pressure polyethylene: Reemergence as a specialty chemical or not?
The analysis results indicate that, while investment capital for new plants favors LLDPE, plant profitability—which is a function of product slate (revenue) and cost—is, in many cases, higher for LDPE plants.
Just over 30 years ago, the first third-party commercial
license was signed for a low-pressure gas-phase polyethylene
(PE) process. This development ushered in the age of the
linear-low-density polyethylene (LLDPE). Benefits of the LLDPE
process were stated as lower capital investment and much lower
energy costs. At the time, it appeared that the conventional
high-pressure tubular and autoclave processes for low-density
polyethylene (LDPE) had been eclipsed by new technology.
Result: Investment in high-pressure PE plants
came to a halt.
