As record amounts of new ethylene capacity continue to be announced globally, so does the number of planned polyethylene units. Currently, more than 190 individual polyethylene units are being proposed around the world, with an estimated nameplate capacity of more than 138 billion pounds per year, according to Industrial Info's project database.

A significant portion of the planned units are in China, where many are integrated into MTO plants and some as part of traditional, naphtha-based ethylene plants. The U.S. makes up the second-largest portion of these new units, with more than 21 billion pounds of planned capacity, while Russia comes in third with an impressive 12.5 billion pounds of planned capacity.

While some of this new capacity is scheduled to come online this year, much of it will reach the market between 2020 and 2022.
