Abstract: Trace element levels of heavy metals such as mercury in crude oil are reduced by contacting the crude oil with an iodine source, generating a water soluble heavy metal complex for subsequent removal from the crude oil. In one embodiment, the iodine source is generated in-situ in an oxidation-reduction reaction, by adding the crude oil to an iodine species having a charge and a reductant or an oxidant depending on the charge of the iodine species. In one embodiment with an iodine species having a positive charge and a reducing reagent, a complexing agent is also added to the crude oil to extract the heavy metal complex into the water phase to form water soluble heavy metal complexes which can be separated from the crude oil, for a treated crude oil having reduced levels of heavy metals.

Abstract: It has been discovered that metals and/or amines can be removed or transferred from a hydrocarbon phase to a water phase in an emulsion breaking process by using a composition that contains water-soluble hydroxyacids. Suitable water-soluble hydroxyacids include, but are not necessarily limited to glycolic acid, gluconic acid, C2-C4 alpha-hydroxy acids, poly-hydroxy carboxylic acids, thioglycolic acid, chloroacetic acid, polymeric forms of the above hydroxyacids, poly-glycolic esters, glycolate ethers, and ammonium salt and alkali metal salts of these hydroxyacids, and mixtures thereof. The composition may also include at least one mineral acid to reduce the pH of the desalter wash water. A solvent may be optionally included in the composition. The invention permits transfer of metals and/or amines into the aqueous phase with little or no hydrocarbon phase undercarry into the aqueous phase. The composition is particularly useful in treating crude oil emulsions, and in removing calcium and other metals therefrom.

Abstract: A process and apparatus to extract and recover heavy metals and sulfur from crude oil or petroleum fuel products including the steps of emulsifying the crude oil with an emulsifying agent, adding a leach solution to the emulsified crude oil and leaching the emulsified crude oil at elevated temperature and pressure to give a leached emulsified crude oil. The leach solution may be acid or alkali. A proportion of the leach solution is extracted for recovering heavy metals. There can also be a microwave hydro-treating step using hydrogen gas at a temperature below 220° C. to ensure there is no quality degradation in the crude feed to produce a desulfurized crude oil and a hydrogen sulphide by-product and recovering sulfur from the hydrogen sulphide by-product.

Abstract: A hinged product has a first section and a second section. The first section has a post extending transversely across one end thereof. The second section two co-axial apertures therein, each of the apertures having an internal wall. The post extends between and through the apertures to connect the first section to the second section. The first section is integrally formed with the second section via at least one connection point connecting the first section and the second section outside of the apertures. Rotating the first section relative to the second section causes the connection point to break and create a two piece hinge.
