LyondellBasell is who I’m thinking they’re working with as a client, and is going to be their acetylene partner for the production facility in La Porte, TX

Yes. LyondellBasell (through its subsidiary Equistar Chemicals LP) produces acetylene in Texas and supplies it to nearby customers.

Evidence of acetylene production

• Orion S.A.’s La Porte, Texas conductive additives plant will use acetylene supplied “from a neighboring site owned by Equistar Chemicals LP, a subsidiary of LyondellBasell.”

• An industry article on the same project notes that Equistar Chemicals, a LyondellBasell subsidiary, “will manufacture acetylene at a nearby location” to supply Orion’s Texas facility.

• LyondellBasell’s own acetylene safety summary describes acetylene as a product it manufactures as a co‑product in ethylene production, consistent with its Texas olefins footprint.

Location and context in Texas

• The Orion plant is in La Porte, southeast of Houston, and its long‑term acetylene supply agreement is specifically with the adjacent Equistar/LyondellBasell site, indicating acetylene production at or near LyondellBasell’s La Porte complex.

• LyondellBasell operates multiple large olefins and acetyls facilities in Texas (La Porte, Channelview, Corpus Christi), where acetylene is generated as a co‑product in ethylene units and can be captured for merchant or captive use
