  • Transportation of sulphur from solid sulphur deposits, in blocks of large dimensions
    Patent number: 8789345
    Abstract: Procedure for the low-risk and zero-emission transportation of sulphur from solid sulphur deposits, in blocks of large dimensions, characterized in that it comprises the formation of blocks of sulphur, having suitable dimensions for being moved, by means of water cut techniques and the wrapping of the blocks obtained in polyethylene sheets.
    Type: Grant

  • Process for the zero emission storage of sulphur
    Patent number: 7712489
    Abstract: A storage tank that stores sulphur with zero emissions uses reinforced EPS panels and an impermeable bottom. The reinforced EPS panels are reinforced with networks of horizontal and/or vertical galvanized or stainless steel wires that are interconnected by galvanized or stainless steel orthogonal wires. Both inner and outer walls of the reinforced EPS panels are plastered before sulphur is placed in the storage tank. Larger storage tanks may be assembled by vertically interconnecting one or more reinforced EPS panels. This interconnection is achieved by corrugating the reinforced EPS panels, or forming their edges in a Greek-key shape. The Greek-key shape prevents sulphur from escaping the storage tank.
