Global Energy Crisis: Why Singapore is Relatively Unscathed-Part 3
Part 3: Vulnerabilities: Sulfuric acid, Helium, and PM Wong’s Qatar trip Oil and gas are not only fuels. Processing them yields by-products that modern industry cannot do without, and the Gulf is a dominant supplier of several. Three matter especially for Singapore: Sulphur, Sulphuric Acid, Helium What they are used for in Singapore • Sulphur. Mostly a by-product rather than a raw material here. Singapore's refineries must strip sulphur out of crude to meet clean-fuel and low-sulphur ship-fuel rules, and recover it as elemental sulphur. Its main industrial use is as the feedstock for sulphuric acid; it is also used in rubber and specialty chemicals. • Sulphuric acid. Ultra-pure "electronic-grade" acid is used in wafer fabs to strip photoresist and clean wafers between hundreds of process steps. Ordinary grades are used in chemical manufacturing on Jurong Island, in metal finishing and plating for electronics and chip packaging, and to control acidity in industrial w...
