A method and system are provided for recirculation of lower alkyldisulphide, such as dimethyldisulphide (DMDS), in a well in which a hydrogen sulphide and sulphur containing fluid is,produced. The method and system are based on the insight that a lower alkyldisulphide reacts with the produced hydrogen sulphide and thereby decomposes into a lower alkanethiol and that the lower alkyldisulphide can be regenerated by selectively separating the hydrogen sulphide from the thus produced lower alkanethiol.
