Who owns PD Glycol LP

PD Glycol LP - Profile

PD Glycol LP is a United States chemical partnership that owns the ethylene oxide and ethylene glycol plant at Beaumont, Texas. The site has roughly 700 million pounds a year of ethylene oxide equivalents capacity and 800 million pounds a year of ethylene glycol capacity. Ethylene oxide is made by oxidising ethylene and is then converted mainly into ethylene glycol, which goes into polyester fibre and film, PET resin for bottles, heat transfer fluids and automotive antifreeze. The partnership was formed as a fifty fifty venture between DuPont and a petrochemical partner whose half interest passed to Equistar Chemicals when Occidental Petroleum contributed its petrochemical assets to the Lyondell and Millennium joint venture in 1998; Equistar, now part of the LyondellBasell group, still holds 50 percent and accounts for it under the equity method.

The disclosed stakes

One row per position. Where a holder reports the same company in two share classes, both rows are shown rather than summed, because the class is part of a position's identity.

Where each figure comes from

A private stake has no ownership form behind it, so the source is always the holder's own filing or disclosure. Anything modelled says so, with the arithmetic.

• LyondellBasell Industries N.V.. Exhibit 21.1 to the FY2025 10-K (filed 20 Feb 2026) states that Equistar Chemicals, LP owns a 50% interest in PD Glycol LP. This is a 50 percent ownership interest, written here as the number 50, not as a fraction of 100. LyondellBasell's balance sheet carries a single combined 'Equity investments' line ($3,963 million at 31 Dec 2025 per the 10-K; $3,875 million at 30 Jun 2026 per the most recent 10-Q) covering all equity-method investees together, so no individual carrying value is disclosed for this venture: value_usd is null. sourcesource 2
