ABSTRACT:
In the processes for the production of solid particulate sulfur by prilling or granulation, wherein molten sulfur emanates from a spray means, such as a prilling device or spray nozzle, interruptions occur in the flow of sulfur from the spray means. The uneven flow of molten sulfur from a spray means can be substantially eliminated by applying vibration to the spray means, preferably in the diection of flow of molten sulfur through the spray means, at a low frequency in the range of 0.2 to 30 cycles per second. The molten sulfur emanating from the spray means is at a temperature of at least one Celsius degree above the melting temperature of sulfur and under a pressure of at least 250 Pa. The flow rate of sulfur from the spray means is uniform and steady, the particulate sulfur product is hard and closely sized, and the emission of sulfur fines discharging from the process is reduced.
