Abstract
A novel process for the preparation of insoluble sulfur product comprises the steps of vaporizing sulfur, mixing the vaporized sulfur with from about 1.times.10.sup.-6 % to about 5% hydrogen sulfide, in the essential absence of hydrocarbon oil, quenching the vaporized sulfur in a quenching medium and separating the insoluble sulfur product from the quenching medium.
Claims5
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.times.10.sup.-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.
