Disclosed is a method for preparing vinyl chloride by catalytic thermal cracking of 1,2-dichloroethane, in which method the heat required for the thermal cracking is supplied via a liquid or condensing heat transfer medium, wherein, the heat transfer medium is heated at least in part by means of waste heat from a plant for combusting liquid and/or gaseous residues of a chemical plant. The invention also relates to a plant for preparing vinyl chloride by catalytic thermal cracking of 1,2-dichloroethane. The heat required for thermal cracking can be obtained from cheaply available waste heat. For example, it is possible to temporarily heat the heat transfer medium exclusively by means of the second heating device operated by waste heat, wherein said waste heat can, for example, be waste heat from a plant for preparing vinyl chloride.

Reduced tube pitch within a shell-and-tube heat exchange reactor such as, for example, an EO reactor, is provided by utilizing a welding material that has a high tensile (i.e., a tensile strength of greater than 600 MPa). Reduced tube pitch allows for more elongated tubes (the tubes are filled with a catalyst) to be present in a reactor, and thus a smaller reactor can be manufactured. Notably, the use of a high tensile strength welding material allows the implementation of a small welding groove located between a beveled sidewall of a beveled upper portion of an opening provided in a tube sheet overlay material (that is located atop a tube sheet) and an outermost sidewall of the elongated tube passing through the opening in the tube sheet overlay material.
