Long Son Thị xã Bỉm Sơn Cement Plant — Vietnam

Long Son Thị xã Bỉm Sơn Cement Plant is a cement plant in Vietnam. Its listed capacity is 5,000,000 t of cement. Cement plants heat limestone to 1,400°C in rotary kilns — one of the hottest industrial processes — and must control temperature precisely across the entire kiln length. It is operated by Long Son Co Ltd. By capacity it ranks #3 among 29 cement plants in Vietnam. It emits about 1,697,313 t CO₂e a year from Climate TRACE. That is 2.1% of the CO₂e from the 90 facilities in Vietnam that have an emissions figure in IndustryAtlas. Its CO₂ per unit of capacity is 6% below the national median for this sector.

Facility data: Climate TRACE v6 (asset-level capacity & CO₂e, CC BY 4.0), id ct-32439366.

In context: how this facility compares

At 5,000,000 t of cement, Long Son Thị xã Bỉm Sơn Cement Plant is well above the median cement plant in Vietnam (2,052,371 t of cement). Subsector: cement. As cement plant, it requires high process heat (typically 800–1400°C) for its core industrial operations, supplied by boilers, furnaces or direct combustion. Cement plants heat limestone to 1,400°C in rotary kilns — one of the hottest industrial processes — and must control temperature precisely across the entire kiln length.

Local climate

Long Son Thị xã Bỉm Sơn Cement Plant sits in a humid subtropical (dry winter) climate zone (Köppen Cwa), at 20.1°N in the northern hemisphere.

Köppen zone: Köppen-Geiger world climate classification (Kottek et al. 2006, 0.5° grid).

Site climate & environmental severity

This site sits in a moderately corrosive environment (estimated ISO 9223 class C3 — Medium), with humidity / wetness the leading environmental stress.

In this site’s local climate, a bare 150 °C surface sheds about 1262 W/m² to ambient — roughly 0.97× the loss at a 20 °C reference. Reference-surface calculation at a 150 °C surface from WorldClim climate normals (ASTM C680 / ISO 12241) — an indicative per-climate comparison, not a measurement of this site’s specific equipment. Open method dataset: DOI 10.5281/zenodo.20787408 (CC BY 4.0).

Indicative estimate via the ISO 9223:2012 informative method (atmospheric corrosivity from temperature, time-of-wetness and airborne salinity), using WorldClim climate normals, the Köppen-Geiger class and coast distance. Indicative, not a measured corrosion rate.
