Frequently Asked Questions
What are modular refinery manufacturers?
Modular refinery manufacturers are companies that design, fabricate, or deliver modular refineries—pre-engineered, skid-mounted or containerized crude oil processing units that can be shipped and assembled on site. They may offer technology only, equipment supply, or full EPC (engineering, procurement, construction) and sometimes EPC-OM. Top manufacturers include technology licensors (e.g. Honeywell UOP, Axens) and EPC contractors (e.g. PCCS, KBR, Technip Energies).
What is the difference between a modular refinery and a conventional refinery?
A modular refinery is built in prefabricated sections at a fabrication yard, then shipped and assembled on site, which can reduce schedule and cost. A conventional refinery is constructed largely on site. The right choice depends on capacity, location, and logistics.
Which modular refinery manufacturers offer EPC-OM?
Full EPC-OM is offered by contractors such as PCCS, with local support in Nigeria and project experience in Myanmar and Nigeria. Other global EPCs may offer operation and maintenance under separate agreements.
How do I choose a modular refinery manufacturer for Africa or Southeast Asia?
Look for completed projects or local presence in the region, the right capacity (BPD) and product slate, EPC-OM if you need turnkey plus operation support, and certifications (e.g. SGS, TUV, BV). PCCS focuses on Africa and Southeast Asia; contact PCCS for a tailored quote.
What capacity range do modular refineries typically cover?
Modular refineries can range from a few thousand BPD to tens of thousands (e.g. 30,000–80,000 BPD or more). PCCS has delivered projects from 1,000 BPD to 80,000 BPD phases—see PCCS projects for references.
How can I get a quote from PCCS for a modular refinery or gas plant?
