  • Sulfur separation process
    Patent number: 4518577
    Abstract: A cyclic process for the removal of H.sub.2 S from a sour gaseous stream is disclosed, the process being characterized by the reaction of the H.sub.2 S to sulfur employing aqueous solutions of oxidizing polyvalent metal chelates of specified organic acids, and by the recovery of the sulfur from the solutions with specific extractants. The extractants are selected from compounds (and mixtures thereof) having the formula C.sub.n H.sub.2(n+1), wherein n is a whole number from 4 through 8, and the recovery may be made prior or subsequent to regeneration of the polyvalent metal chelate solution.
    Type: Grant
    Filed: December 20, 1982
    Date of Patent: May 21, 1985
    Assignee: Shell Oil Company
    Inventor: Miro E. Klecka
  • Removal of H.sub.2 S from sour gas streams with subsequent sulfur separation
    Patent number: 4517170
    Abstract: A cyclic process for the removal of H.sub.2 S from a sour gaseous stream is disclosed, the process being characterized by the reaction of the H.sub.2 S to sulfur employing aqueous solutions of oxidizing polyvalent metal chelates of nitrilotriacetic acid, and by the recovery of the sulfur from the solutions with specific extractants. The extractants are selected from compounds (and mixtures thereof) having the formula C.sub.n H.sub.2(n+l), wherein n is a whole number from 4 through 8, and the recovery may be made prior or subsequent to regeneration of the polyvalent metal chelate solution.
