Abstract:
A method for removing hydrogen sulfide from liquid sulfur, comprising:introducing liquid sulfur containing hydrogen sulfide in an upstream portion of a conduit, the conduit having a fluid outlet in a downstream portion thereof located within a lower portion of a first vessel; causing the liquid sulfur to flow through the conduit outlet into the first vessel up an annulus formed between the conduit and the first vessel and overflow through an outlet positioned at an upper portion of the first vessel into a second vessel which is connected to a liquid sulfur pit operating at atmospheric pressure; introducing air into the liquid sulfur located in said annulus at a point between said conduit outlet and said first vessel outlet; and causing the air to flow concurrently to the direction of flow of the liquid sulfur in said annulus and out of said first vessel outlet into said second vessel thereby removing hydrogen sulfide from the liquid sulfur in said annulus.
