Zinc-based sulfur compound scavenger with reduced solids deposition

A method for scavenging a sulfur compound from a fluid comprising a hydrocarbon, water, and the sulfur compound selected from the group consisting of H2S, sulfide, bisulfide, and combinations thereof, the method comprising:

• injecting at least one zinc-based sulfur compound scavenger into the fluid in an amount effective to at least partially scavenge the sulfur compound from the fluid, where the at least one zinc-based sulfur compound scavenger is selected from the group consisting of a zinc carboxylate, a tetramine zinc carbonate, a zinc carbonate, a zinc ammonium carbonate, a zinc chelate, a zinc lignosulfonate, and combinations thereof;
• and
• injecting at least one zinc sulfide deposition preventer into the fluid in an amount effective to at least partially prevent the deposition of zinc sulfide from the fluid, where the at least one zinc sulfide deposition preventer is selected from the group consisting of sodium salts of a phosphorous-based polymer, polymeric ammonium salts, acrylic sulfonate non-ionic terpolymers, modified acrylic acid polymers, and combinations thereof;
• where injecting the at least one zinc-based sulfur compound scavenger and injecting at least one zinc sulfide deposition preventer occurs in any order or simultaneously.

A sulfur compound scavenged fluid comprising:

• a hydrocarbon;
• water;
• the sulfur compound selected from the group consisting of H2S, sulfide, bisulfide, and combinations thereof;
• at least one zinc-based sulfur compound scavenger in an amount effective to at least partially scavenge the sulfur compound from the fluid;
• and
• at least one zinc sulfide deposition preventer into the fluid in an amount effective to at least partially prevent the deposition of zinc sulfide from the fluid.
