Abstract
Systems and methods for sulfur-compound removal from hydrocarbon liquids may include at least one tank defining a chamber with top and bottom ends, a gas inlet into the chamber, a gas outlet from the chamber, a fluid inlet into the chamber, and a fluid outlet from the chamber. A fluid circulation assembly creates a hydrocarbon liquid flow on a liquid path, and a gas circulation assembly circulates a gas flow along a gas path. The gas inlet and outlet and the fluid inlet and outlet of the tank may be arranged to create a crossflow and counterflow of the liquid and gas flows in the chamber of the tank such that sulfur-containing compounds are transferred from the liquid to the gas flow. A gas processor assembly may remove sulfur-containing compounds from the gas flow before recirculating the gas flow. The gas flow may be predominantly nitrogen (N2) gas.
