Method for removing a hydride of an element selected from the group consisting of phosphorous, arsenic, antimony, bismuth, or mixtures thereof, from a hydrocarbon stream, a gas stream, or a mixture of the two streams by initially reducing the free water concentration of the stream or streams or raising the temperatures of the same and subsequently contacting the essentially moisture free effluent with soda lime.
