LyondellBasell Houston Turnaround Schedule 2026: Vendor Positioning Guide
Turnaround timing, vendor qualification, and procurement structure at LyondellBasell's Houston refinery and Channelview chemical complex.
LyondellBasell operates a 268,000 barrel per day refinery in Houston along the Houston Ship Channel, making it one of the largest refineries in the Houston metro area. Adjacent to the refinery, LyondellBasell's Channelview chemical complex is one of the largest olefins and polyolefins production sites in the Americas. Together, these facilities create an integrated refining and petrochemical operation that generates turnaround and maintenance demand across both traditional refining services and chemical plant specialties.
Facility overview
The Houston refinery processes heavy, high sulfur crude oils and produces gasoline, diesel, jet fuel, and chemical feedstocks. The facility's coking capacity is a defining feature, allowing it to process some of the heaviest crude grades available in the market. Major process units include crude and vacuum distillation, coking, fluid catalytic cracking, hydrocracking, catalytic reforming, alkylation, and sulfur recovery. The refinery's heavy crude processing capability differentiates it from lighter crude refineries and creates specific equipment and service requirements related to high temperature, high pressure, and corrosive process conditions.

The Channelview complex operates multiple ethylene crackers, propylene oxide and styrene monomer production units, and polyethylene reactors. The site produces ethylene, propylene, butadiene, benzene, propylene oxide, styrene monomer, and various polyolefin grades. The chemical complex's cracker furnaces require periodic decoking and tube replacement on their own maintenance cycle, which generates demand for specialty metallurgy, high alloy welding, and furnace related services that complement but differ from traditional refinery turnaround scopes.
LyondellBasell announced in 2023 that it would exit the refining business, with the Houston refinery expected to cease crude oil processing by the end of 2025. However, the company indicated it would explore options for the facility including conversion to alternative uses. Vendors should verify the current operational status of the refinery before pursuing turnaround opportunities there, while the Channelview chemical complex continues normal operations on its established maintenance cycle. See the Texas refinery turnaround schedule 2026 for broader context.
Turnaround scope and timing
The Channelview chemical complex operates on a 4 to 5 year major turnaround cycle for primary cracking and downstream units. LyondellBasell discloses aggregate maintenance and turnaround spending in quarterly earnings, with the Olefins and Polyolefins Americas segment showing elevated capital spending in years with major planned outage activity. Based on cycle timing, the Channelview complex falls within expected turnaround windows for the 2026 to 2027 period.
Major turnaround events at Channelview involve cracker furnace decoking and tube replacement, quench system maintenance, compression train overhaul, cold box and fractionation column maintenance, and downstream reactor catalyst changeouts. The ethylene cracker turnaround is the highest value event, typically lasting 30 to 45 days and involving specialized contractors for furnace work, transfer line exchanger maintenance, and cryogenic equipment overhaul in the cold section of the plant.
Vendor qualification
LyondellBasell requires safety prequalification through ISNetworld for all contractors entering its facilities. The company maintains corporate level approved vendor lists for major equipment and material categories, managed from its Houston headquarters. Site level procurement handles turnaround specific material requisitions and service contractor management.
For the Channelview chemical complex, vendors must demonstrate petrochemical specific capabilities beyond standard refinery qualifications. This includes experience with ethylene cracker furnace tube metallurgy (typically HK 40 and HP modified alloys), cryogenic equipment maintenance, high speed rotating equipment for ethylene and propylene refrigeration compressors, and polymer reactor maintenance. The engineering standards at Channelview reflect LyondellBasell's European heritage and may reference DIN or EN standards alongside API and ASME codes for certain equipment categories.
The turnaround manager and maintenance manager at Channelview control service contractor selection. Reliability engineers and process engineers influence equipment specifications and replacement decisions. Vendors pursuing Channelview turnaround work should build relationships with both the turnaround planning organization and the reliability engineering group to ensure visibility into upcoming scopes and equipment requirements.
