ExxonMobil high-pressure tubular process has been in operation since 1968 with a long history of improvements and capacity expansion. ExxonMobil's world-scale tubular reactors enable licensees to produce polyethylene at a low total cost comparable to commercial gas-phase reactors. With our high-pressure tubular technology, licensees can produce:
Compared to other processes, the advantages of ExxonMobil’s high-pressure tubular technology are:
As a result of high conversion rates, tubular technology achieves lower operating costs than autoclave technology. However, with either high-pressure tubular or high-pressure autoclave technology, licensees can expect outstanding safety, process flexibility, capacity and product quality.
Fifteen tubular lines operated by ExxonMobil and/or using ExxonMobil technology capable of producing more than 2,500 kta are located in:
