Definitions

  • the temperature of the gas phase feedstocks has to be raised (e.g. from 390 ° C. to 430 ° C.). After all, the system should be able to be started up quickly - if possible without additional heating capacity.
  • the invention is based, to ensure despite the variable heat output of the mash heat exchanger, an adjustment of the desired temperatures for the mash, the intermediate separator and the gas phase feedstocks and to achieve an economical heat recovery of the hydrogenation products. Furthermore, starting the plant should not require an additional heating furnace for the gas phase hydrogenation.
  • the temperature of the gas phase feedstocks must gradually be raised. This takes place - without an additional heating furnace - according to the invention in that the temperature level of the head cooler upstream of the intermediate separator is also increased as the mash heat exchanger progresses. At the same time, with increasing reduction in the heat transfer capacity of the mash heat exchanger, the waste heat generated from the bottom phase hydrogenation is transferred to the upstream mash preheating of the bottom phase hydrogenation via the path of gas phase hydrogenation and thus used economically.
  • the desired temperature in the intermediate separator is set by means of a final cooler, in which steam is expediently generated or hydrogenation gas is preheated.
  • the temperature level of the bottom phase gases / vapors entering the mash heat exchanger can also be reduced. This reduces the usual fast incrustation of clean pipes of the mash heat exchanger, since the max. occurring mash temperature (at the same averaged mash outlet temperature) is reduced.
  • the bypass around the mash heat exchanger serves to limit the max. Mash outlet temperature of the mash heat exchanger (especially when the heat exchanger tubes are clean).
  • the start-up process is carried out quickly by heating the gas phase feedstocks using a head cooler behind the bottom phase hydrogenation.
  • the process is explained in more detail using two examples:
  • the gaseous and vaporous products from the bottom phase reactor 4 are partially cooled by means of mash heat exchanger 2 by indirect heat exchange, the mash-hydrogenation gas mixture being heated to the starting temperature of the bottom phase hydrogenation of approximately 440 ° C. on the heating side.
  • the bottom phase products are further cooled by indirect heat exchange in the head cooler 7 and in the final cooler 8.
  • the products from the bottom phase hydrogenation are divided into the solvent fraction (liquid) and the feed stream for the gas phase hydrogenation (gases / vapors). The latter is heated in the head cooler 7 and then in the indirect heat exchanger 10 to the gas phase reaction temperature of approximately 390 ° C.
  • the gas phase products are partially cooled by indirect heat exchange in the mash heat exchanger 1, whereby the mash-hydrogenation gas mixture is preheated.
  • the hydrogenation gas is preheated by further cooling of the gas phase products.
  • the entire process is self-sufficient in stationary operation.
  • the mash heating furnace 3 serves only as a start-up furnace.
  • the gaseous and vaporous products from the hot separator 5 can be cooled somewhat before entering the mash preheater 2. In this way, the incrustation in the mash heat exchanger is reduced.
