A process is provided for producing elemental sulphur from a hydrogen sulphide and sulphur dioxide containing gas stream by a Claus type of catalytic reaction. The process is based on the discovery that the conventional Claus catalyst, in the presence of liquid sulphur and at pressures considerably greater than one atmosphere, is significantly active toward the Claus catalytic reaction. Thus, in accordance with the invention, increasing the pressure of the reaction in the presence of liquid sulphur increases both the catalytic activity and the elemental sulphur conversion. The process involves introducing a compressed hydrogen sulphide and sulphur dioxide containing gas stream into a catalytic reactor and reacting the gases in a Claus catalyst bed in the reactor to produce elemental sulphur under conditions of temperature and pressure such that water in the reactor exists only as water vapor and sulphur vapor is condensed in the catalyst bed, being removed therefrom as a liquid. The pressure within the reactor is preferably between 5 and 50 atmospheres absolute.
A sulphur producing process in which hydrogen sulphide and sulphur dioxide gases are continuously introduced into a reactor containing a bed of a catalyst which causes these gases to react to produce elemental sulphur, wherein said gases when in the reactor are maintained at such conditions of temperature and pressure that free water in the reactor exists only as water vapour and sulphur is condensed in the catalyst bed, and wherein said sulphur is continuously removed from the bed as a liquid while the bed is continuously maintained substantially saturated with liquid sulphur, and wherein the pressure in the reactor is maintained at at least 5 atmospheres absolute.
A continuous process for producing sulphur from the tail gas of a conventional Claus sulphur plant, comprising the steps of:
A method for treating a gas stream containing hydrogen sulphide and sulphur dioxide to produce elemental sulphur and an effluent stream of reduced hydrogen sulphide and sulphur dioxide content comprising the following steps:
Apparatus for reacting hydrogen sulphide and sulphur dioxide gases together to remove sulphur from said bases, including:
