As the economic engine of Brazil and broader Latin America, the State of São Paulo is leading a major energy transition. The massive sugar-cane ethanol industrial complexes in Campinas, Ribeirão Preto, and the ABC Paulista petrochemical clusters are increasingly converting organic residues and refinery off-gases into valuable energy sources. Central to this process is the commercial production of biomethane (biometano).
However, raw biogas from landfills and vinasse digestion contains elevated concentrations of hydrogen sulfide (H₂S), which can range from 1,000 ppm to over 10,000 ppm. Under CETESB (São Paulo State Environmental Agency) and CONAMA (National Environmental Council) Resolution 382/2006, industrial facilities must enforce strict sulfur oxides (SOx) limits. This requires desulfurization units that can consistently achieve up to 99.9% H₂S removal efficiency.
Deploying energy and chemical purification systems in Brazil involves navigating complex compliance frameworks. Crucially, all pressurized equipment, including desulfurization gas scrubbers, separators, and distillation units, must fully comply with Regulatory Standard NR-13 (Norma Regulamentadora 13). NR-13 dictates strict guidelines for pressure vessel design, material traceability, inspection frequencies, and safety documentation.
Our engineering services utilize advanced finite element analysis (FEA) to ensure that all standard and non-standard pressure vessels built in our Chinese facilities comply with ASME Sec VIII Div 1 design rules and are pre-audited for rapid NR-13 local certification upon arriving at Brazilian ports like Santos.
"To successfully enter Brazil’s gas infrastructure, desulfurization equipment must survive demanding operating environments, including high ambient humidity and corrosive H₂S atmospheres. Complete material traceability (EN 10204 3.1) and ASME-compliant engineering are non-negotiable requirements for tier-one project financing in South America."
Multinational energy developers operating in South America are increasingly shifting from fragmented regional suppliers to integrated manufacturing partners capable of delivering turnkey solutions. Project developers require desulfurization skids that combine physical separation, chemical absorption, and advanced process automation on a single transportable base frame. Choosing centralized manufacturing guarantees identical system configurations across global assets, simplifying operations, maintenance, and training.
