1950 - 1959 Phosphorus chemistry arrives in Knapsack

1950

The production of molochloraecetic acid begins and the manufacturing of ferrosilicon is restarted.

1951

Production runs again in all areas.

In the course of reorganizational measures of the former IG FARBENINDUSTRIE AG (Aktiengesellschaft/AG=corporation), the following companies merge to become

  • AKTIENGESELLSCHAFT FÜR STICKSTOFFDÜNGER Knapsack;
  • GRIESHEIM-AUTOGEN Frankfurt/Main;
  • NORDWESTDEUTSCHE SAUERSTOFFWERKE Düsseldorf;
  • TEGA WERK, FABRIK TECHNISCHER GASE Kassel-Bettenhausen;
  • SÜDWESTDEUTSCHE SAUERSTOFFWERKE Stuttgart-Untertürkheim.

Dr. Friedbert Ritter is named chairman of the board of Knapsack-Griesheim AG (corporation) and is concurrently a member of the board of the Farbwerke Hoechst AG.

1952

The company is released from allied forces control and changes its name to KNAPSACK-GRIESHEIM AKTIENGESELLSCHAFT (corporation), Knapsack. In the course of the divergence, the corporation’s stocks are transferred back from IG FARBEN INDUSTRIE i.L. (in liquidation) to the FARBWERKE HOECHST AG VORM. MEISTER LUCIUS & BRÜNING, Frankfurt/Main.

The acquisition of the majority interest in the FRIEDRICH UHDE GMBH (Ltd), Dortmund and the procurement of the equity holding in the companies DECKER & CIE. GMBH, Köln and PAUL EISENHARDT; SENFFABRIK UND ESSIGESSENZ-VERKAUFS-GESELLSCHAFT MBH (Ltd.), Düsseldorf follows.

Conversion of the acetone plant from acetic acid to isopropanol takes place. In September the first phosphate rock silo cells are erected in the harbour at Godorf.

The chairman of the new company’s supervisory board is Karl Winnacker, chairman of the board of the Farbwerke Hoechst AG (corporation).

Staff members: over 3000 employees

1953

Phosphorus production’s beginnings: elemental phosphorus, thermal phosphoric acid, red phosphorus, and the manufacture of acetylene carbon black (combustible carbon black).

1954

Vinyl chloride production based on acetylene begins and ferrosilicon powder, produced according to the company’s own processes, is available for supply.

1955

Commissioning of the company’s own fully enclosed carbide furnace (carbide furnace 10) with an output of 40 MW takes place. The new technology allows for a considerable improvement in plant productivity and environmental protection.

In the phosphorus sector, the phosphate sintering plant 1 also goes into production.

1956

Production of pentasodium triphosphate and tetra sodium pyrophosphate begins using the company’s own processes in April (spray tower 1) and a second phosphorus furnace with an output of 50 MW is commissioned in October.

Pentasodium triphosphate as well as sodium tripolyphosphate, so called NTPP serves as a basis for modern detergent formulas. It provides for the successful development of the phosphorus chemical sector for over three decades. Dedication of the so-called “Knapsacker Feierabendhaus” (conference and entertainment facility)

1957

Further new products from Knapsack include chloroprene and acrylonitrile.

The number of employees increases further to over 4,000.

On 16 January Dr. Hugo Querengässer becomes the permanent deputy of Dr. Janning acting as works manager of the Knapsack works and he is then appointed as works manager on 30 June 1961. Querengässer becomes a member of the board on 17 September 1962.

1958

The commissioning of a second fully enclosed carbide furnace (carbide furnace 20) allows for the closing down of five smaller furnaces.

1959

The reorganization of the Knapsack-Griesheim Aktiengesellschaft (corporation) takes place, whereby the company name is retained, and it is turned into a plant/operational management company of Farbwerke Hoechst Aktiengesellschaft (corporation).

ENERGY SUPPLY

The reliable and economical supply of sufficient energy is one of the most important prerequisites for the chemical industry. The chemical park operator InfraServ Knapsack provides the manufacturing companies with the necessary energies in the form of electricity and process steam.

The continuous main load of the energy supply is borne by the refuse-derived fuel (RDF) power plant of E.ON Energy from Waste, where up to 300,000 tons of refuse-derived fuel are thermally utilized every year. This service is complemented by the combined cycle gas turbine (CCGT) power plant of the Norwegian energy company Statkraft. With 800 MW of installed capacity it is one of the largest CCGT power plants in Germany. A further combined gas turbine power plant with capacity of 400 MW is currently under construction. The energy supply of the Chemiepark Knapsack is thus guaranteed, also at peak load time.
