Abstract

A process for scavenging hydrogen sulphide from a mixed phase system, in particular a hydrocarbon fluid having a liquid phase and a gaseous phase, is described. The hydrocarbon fluid contains a high level of hydrogen sulphide, which can be above 5000 ppm by weight in the gaseous phase of the fluid prior to treatment. Formaldehyde, preferably water, with is added to the fluid. The process is particularly useful for in-line scavenging of hydrogen sulphide from sour crude oil containing very high hydrogen sulphide levels. The hydrogen sulphide content of the crude oil that is delivered to the platform is reduced to safe and commercially acceptable levels and solid by-product formation is insignificant. This process thus advantageously provides a low cost manner of developing sour oil fields that would otherwise not be safe or economically viable to develop or advantageously provides a way of modifying existing processes of handling sour hydrocarbon fluids, for example, within oil fields already in production, such that the method according to the present invention replaces existing methods adopted.
