A process for the preparation of a stable insoluble sulfur product having improved flow characteristics and containing substantially no tailings which comprises forming a mixture of vaporized sulfur with hydrogen sulfide in an amount ranging from about 1×10-6% to about 5% hydrogen sulfide by weight

A process for the preparation of a stable insoluble sulfur product having improved flow characteristics and containing substantially no tailings which comprises forming a mixture of vaporized sulfur with hydrogen sulfide in an amount ranging from about 1×10-6% to about 5% hydrogen sulfide by weight of sulfur and in the essential absence of hydrocarbon oil, quenching said mixture in a quenching medium to form said insoluble sulfur product and separating said insoluble sulfur product from said quenching medium.
