Arrangements for furnishing plans and apparatus for setting up the T52 installation at Scholven are discussed and some specifications for its operation are given, especially as compared to the operation at Poelitz. Some of the equipment included buffer flasks, heat exchangers, electric preheaters, coolers, pressure-letdown apparatus, product separators, etc. Scholven needed to use a 600-mm-diameter, 12-m-long heat exchanger with 301 small tubes, whereas Poelitz could get by with a 500-mm diameter heat exchanger. It seemed better operationally to use electric preheaters rather than steam preheaters, and the electric apparatus could probably be loaned by Gelsenberg or Poelitz, each of which had just changed partially to operation with catalyst 7019. Some of the specifications for operation at Scholven included the following: maximal throughputs of 52,000 m/sup 3//hr of gas and 6,500 kg/hr of product, with the respective densities being 0.2 kg/m/sup 3/ and 1.0 kg/liter; temperature changes in the heat exchanger of from 35/sup 0/C to 195/sup 0/C for entering material and from 270/sup 0/C to 105/sup 0/C for exiting material (requiring 190 m/sup 2/ of exchange surface); K-value for heat exchanger of 230 Cal/m/sup 2///sup 0/C/hr; temperature change in water cooler of from 110/sup 0/ to 45/sup 0/ for product and from 20 to 55/sup 0/C for water (a heat exchange of 1,300,000 Cal/hr, requiring 125 m/sup 2/ of exchange surface); and pressure drop of 15.0 atm in the system, with 10.0 atm of it appearing in the pressurizing system for cold gas. Scholven's T52 installation was to produce much more product than Poelitz's (22,000 metric tons/yr vs 12,000 metric tons/yr). Finally, the report gives a table comparing specifications on heat exchangers used at several plants. 2 tables.
