About the Manufacturer

BOSHIYA Group — Oil Refinery Equipment Manufacturer & Supplier

Look, there are a lot of companies that stamp “refinery equipment” on their website and call it a day. We’ve been doing this since 1915. Not always refinery work — the first few decades were mostly boilermaking and structural steel — but by the 1960s we were fabricating our first distillation columns and pressure vessels for petroleum refineries across East Asia. That history matters when you’re buying equipment that runs at 400°C and 50 bar for years on end.

Fabrication Capability

Today BOSHIYA operates three fabrication facilities with a combined shop floor of about 120,000 square meters. We hold ASME U and U2 stamps, API monograms for key product lines, CE/PED certification for European markets, and ISO 9001 across all plants. Our annual output capacity sits around 60,000 metric tons of finished equipment — reactors, columns, heat exchangers, storage tanks, pipe spools, the works.

Global Engineering Team

We’ve shipped to 43 countries at last count. The Gulf states, West Africa, Southeast Asia, Central Asia, South America. A lot of repeat customers, which honestly tells you more than any certification badge can. The engineering team is about 85 people — process, mechanical, piping, electrical, instrumentation — and we keep a full-time QA/QC department with Level III NDE examiners on staff. Not subcontracted. On staff.

Wholesale Oil Refinery Equipment — OEM, EPC & Fleet Supply

About 60% of our volume goes through EPC contractors and engineering firms — companies like Technip, Saipem, and regional EPCs. They don’t buy one vessel at a time. They buy entire equipment lists for refinery construction or turnaround projects.

60% Volume via EPCs
Phased Delivery Schedule

How We Work With EPCs

An EPC wins a contract (e.g., a 50,000 bpd refinery). They issue a requisition package — maybe 40 to 120 line items. We quote the lot, negotiate on the heaviest items, and lock in a fabrication schedule that maps to their erection sequence. Phased delivery means nothing sits in a laydown yard for six months collecting sand.

Fleet Buyers & OEM Partnerships

For repeat customers, we offer blanket pricing on standard vessel designs. If you order the same separator spec across multiple projects, we keep drawings on file and pre-qualify materials, cutting lead times by 20–30%. For OEM partners with proprietary designs, we fabricate strictly to your drawings under your QA protocol.

MOQ Policy Flexible

Heavy Reactors: MOQ = 1 unit.
Standard Exchangers: Typically MOQ = 3 units (to justify production run).
Modular Packages: Always project-specific, no minimums.

Problems We Solve for Oil Refineries — And the Projects That Prove It

Refineries don’t call us when everything is going well. They call when a turnaround deadline is slipping or when they need 86 pressure vessels. Here are the real scenarios we handle.
⚠ The Problem

Turnaround Deadlines With Zero Margin

Refineries lose $500k to $2M per day of unplanned downtime. When a turnaround window is 28 days, you can’t afford equipment that shows up on day 29.

Our Approach

We stage critical spares, run parallel fabrication streams, and ship pre-tested assemblies to minimize on-site work.

✓ PROJECT EVIDENCE: GULF COAST CDU Delivered 42 valve trays & 6 re-tubed exchangers in 19 days. Unit back online 2 days ahead of schedule.
⚠ The Problem

Vendor Quality You Can’t Verify From 8,000 Miles Away

Overseas buyers worry about getting equipment that doesn’t match the spec. We’ve seen competitors ship vessels with undocumented material substitutions.

Our Approach

Third-party inspection from day one (Lloyd’s, BV, TUV). Full MDR with real-time photo documentation. You can send your own QA team — we clear the schedule for them.

⚠ The Problem

Modular Refinery Failing in Tropical Conditions

Modular refineries designed for temperate climates often fail in West Africa and the Gulf — corrosion, overheating, and condenser fouling within the first year.

Our Approach

We spec for the environment, not the catalog. Duplex stainless for coastal overheads, oversized air-fin coolers for 48°C ambient.

✓ PROJECT EVIDENCE: NIGERIA MODULAR PLANT Hit 4,800 bpd throughput within 6 months of commissioning. Zero thermal derating issues.
⚠ The Problem

Aging FCC Internals Bleeding Money on Catalyst Loss

Cyclone efficiency below 99.5% sounds fine, until you calculate $2 million a year in lost catalyst at a 45,000 bpd feed rate.

Our Approach

Reverse-engineer OEM designs when drawings are lost. Fabricate complete Stellite hard-faced internals. Pre-assemble in shop.

✓ PROJECT EVIDENCE: SOUTHEAST ASIA Improved efficiency: 99.5% → 99.92%. Installation completed in 9 days.
★ FEATURED CASE STUDY

86 Pressure Vessels for Gulf Conversion Refinery

The Challenge: A national oil company needed 86 ASME Div 1/2 vessels with NACE MR0175 compliance for a new 200,000 bpd refinery. The order sheet ran to six pages.

The Execution: Their QA team spent four days in our shop auditing welding procedures before the first cut. We delivered in eight phased shipments over 14 months. Two vessels were flagged during final radiography; we cut, re-welded, and re-documented immediately.

✓ FINAL RESULT On-time delivery rate: 100%. All 86 vessels cleared site acceptance.
“We evaluated seven manufacturers for this package. BOSHIYA’s documentation quality and willingness to accommodate our QA protocols set them apart.”

01 / HYDROCARBONS

What is a hydrocarbon and how does it relate to crude oil production?

Hydrocarbons are molecules built from hydrogen and carbon — they're the primary building blocks of crude oil. During crude oil production, what comes out of the ground is a mix of thousands of different hydrocarbon molecules. Refineries and petrochemical facilities separate, crack, and reform this mix into valuable products like gasoline, diesel, and feedstocks. Think of crude as raw ingredients and the refinery as the kitchen.
02 / DISTILLATION

How does a distillation tower separate crude oil based on their boiling points?

Crude oil is heated to 350–370°C and fed into the tower. Components with lower boiling points rise and vaporize at the top (light naphtha, LPG), while heavier fractions condense lower down. Kerosene, diesel, and atmospheric residue are pulled at various tray levels 24/7. One column can separate crude into numerous petroleum products.
03 / OPERATIONS

Why does a refinery run 24 hours a day, 365 days a year?

It's driven by economics; shutting down and restarting costs millions and can take over a week to stabilize. Continuous operation maximizes the capacity to process thousand barrels of crude oil per calendar day. A planned turnaround happens every 3 to 5 years and can cost between $50 and $500 million.
04 / SAFETY & ENVIRONMENT

What safety and environmental risks are associated with oil refinery operations?

Risks include fires, explosions, and toxic exposure like hydrogen sulfide. Modern safety relies on gas detection, pressure relief, and emergency shutdown systems. Environmental risks involve air/water emissions and flaring. Investment in closed-loop systems and vapor recovery units captures what previously went to the flare stack.
05 / PRODUCT MIX

What products come from an oil refinery besides gasoline and diesel?

Beyond fuels, refineries produce jet fuel, kerosene, heating oil, lubricant base stocks, asphalt, petroleum coke, and petrochemical feedstocks like naphtha and LPG. These feedstocks become raw materials for chemicals and plastics found in packaging and medical equipment.
06 / REFINING PROCESS

How do refineries turn crude oil into various fuels?

The process involves separation (distillation) and conversion. Catalytic cracking and hydrocracking break heavy gas oil into lighter, cleaner fuels. Reforming boosts octane in naphtha for gasoline, while hydrotreating removes sulfur to meet emission standards.
07 / MOLECULAR QUALITY

How do different hydrocarbon molecules determine product quality?

Small, straight-chain molecules are ideal for gasoline, while branched and cyclic molecules affect octane. Larger molecules at the bottom of the column suit diesel, lubricants, or asphalt. Sulfur and nitrogen are impurities that must be removed via hydrotreating.
08 / GLOBAL MARKET

Who are the major players in refining and how do capacities affect supply?

Major operators include Marathon Petroleum, Valero, ExxonMobil, and Saudi Aramco. Jamnagar in India is the world's largest refinery at 1.24 million barrels per day. The U.S. has approximately 132 operating refineries with a combined capacity of ~18.4 million barrels per day. Refinery maintenance can impact regional gasoline prices within days.
