ABSTRACT:
An apparatus and process are provided for the transport of molten sulphur in pipelines having mantle heating by means of a liquid medium heated to a temperature above the melting point of sulphur, which reduce transport costs and technology and energy expenditures. Petroleum from an associated pipeline is used as the heating medium. The sulphur pipeline (10) is laid in the area of the petroleum pipeline (1). The pipeline has at least one in-line pump station (7, 8, 9) for the increase of the transport pressure of the petroleum, and the petroleum used as the heating medium is reheated and brought to a higher pressure in one of these pump stations. The molten sulphur (23) is again brought up to a sufficient transport pressure in the at least one pump station (7, 8, 9).
