More Information
Summary:FIELD: oil and gas production. SUBSTANCE: invention relates to sulfur concentrates and sulfur sludges formed in hydrogen sulfide-containing gas treatment processes. Sulfur-containing raw material is melted in calcium chloride aqueous solution with boiling temperature exceeding melting point of sulfur by 5-15 C, while 1-3 ml of solution is taken per 1 g of sulfur concentrate. EFFECT: facilitated sulfur isolation process.
