Fuel-Grade Pet Coke (Green)

Green coke by sulphur, HGI & calorific value

Fuel-grade petroleum coke — green coke, uncalcined, straight off the delayed coker — is contracted against a short list of numbers that decide whether it works in your kiln or burner. Sulphur is the first and primary constraint: traditional US Gulf and Middle Eastern cokes average 4.5–6.5% S, requiring careful blending to meet kiln SO₂ limits and prevent preheater build-up. In the Atlantic Basin, a major structural shift occurred with the full commercial operation of Nigeria's 650,000 bpd Dangote Petroleum Refinery in Lekki. Featuring a massive 4-drum Delayed Coking Unit (DCU) producing 3.0+ Mtpa of green coke running on low-sulphur Nigerian sweet crudes (Bonny Light, Forcados, Agbami), Dangote yields premium low-sulphur green pet coke at 0.8%–1.5% S, high calorific value (NCV ≥ 8,250 kcal/kg), and superior Hardgrove Grindability (HGI 40–48). This provides Atlantic cement and lime kilns with a low-emission, high-energy fuel that reduces or eliminates the need for expensive desulphurisation additives.

Hardgrove Grindability Index (typically 35–45, with premium sponge cokes reaching 45–50) determines whether your vertical roller or ball mill can pulverise the coke at full rated capacity. Net calorific value runs ≥ 8,000 kcal/kg and often 8,200–8,500 kcal/kg, which is the whole commercial case: pet coke undercuts seaborne thermal coal on delivered cost per gigacalorie while moving fewer freight tonnes. Volatile combustible matter (8–12%) drives ignition behaviour and flame stability, total moisture (≤ 8%, often 6–8% as shipped) is deadweight you pay freight on, and ash is remarkably low at ≤ 0.5%.

You buy fuel-grade rather than calcined coke when you are burning it, full stop — cement precalciners and kilns, circulating fluidised-bed and pulverised-coal power boilers, lime and glass furnaces, and blending with coal to lift the calorific value of a low-rank feed. CBIL brokers fuel-grade green coke from Dangote Lekki, US Gulf and Chinese sources, and from the Saudi Red Sea (Yanbu) subject to confirmation of loading, connecting refinery and trader allocations with industrial off-takers against SGS or Intertek certification of sulphur, NCV, HGI, VCM, ash and moisture. Supply is structured in bulk Handysize and Supramax parcels on FOB and CFR terms around your discharge port and burn schedule — send your sulphur ceiling and mill HGI floor and we will work the allocation to it.
