Krupp Uhde

One of the reactors that Degussa and the plant manufacturer Krupp-Uhde are currently inveshgating in the framework of a government-funded project has remarkably large outer dimensions and is being tested for pilot-scale feasibility (see Figure 1.23). 

BASF activities have shown that one can make money by investigating gas-phase reactions for process development. If Degussa and Krupp-Uhde have built a very large micro reactor with outer dimensions of more than 1 m, obviously there must be an economic reason for that.

Krupp Uhde has more than 40 years of experience in the design and construction of chlorine/caustic soda plants [1]. The company s 150 plants throughout the world have an overall production capacity of approximately 8 million metric tonnes per year of NaOH (100%) and thus make Krupp Uhde unique in its field. 

Research and development work on membrane technology was begun jointly with Hoechst AG, Bayer AG and Uhde GmbH in 1973 when the first commercial membranes became available. Until now, Krupp Uhde s know-how has been based on the combined efforts of these three companies in the research and development of this technology. One result is the Single Element patented in Europe in 1980 by Hoechst AG [2] followed by patent applications all over the world [3]. 

In 1998, Krupp Uhde became the sole owner of Single Element Technology and continues to put great effort into the further development of membrane cell technology for different electrolysis applications. With a new patent [4] for improved Single Element Technology, Krupp Uhde is ready for the future. 

Krupp Uhde (KU) know-how and technology is based on extensive experience in chlorine production and provides clients with short shutdown periods for the conversion of chlorine plants to membrane technology, low-energy consumption and includes special technologies for higher chlorine quality and hydrogen-free production. 

This technical leadership together with the Krupp Uhde know-how and the licence for the membrane process - which makes Krupp Uhde the only licensor and contractor able to supply complete plant complexes from one source - is the basis for the ongoing success of Krupp Uhde Single Element Technology for electrolysis applica-...

With Krupp Uhde know-how and technology, new plants and conversions, future-oriented technologies, after-sales service and plant monitoring are all offered with increased profits on products, reduced capital expenditure and increased turnover converging to an improved Rol.

In 1997 Bayer AG increased chlorine production at its Uerdingen site by adding Krupp Uhde membrane electrolysers to the existing mercury cells. In order to achieve a high chlorine quality (minimum oxygen concentration) and maximum chlorine yield, the acidic process is run - namely the brine leaves the cells at a low pH of 2.5-3.

The synthesis loop consists of a recycle compressor, feed/effluent exchanger, methanol reactor, final cooler and crude methanol separator. Krupp Uhde s methanol reactor is an isothermal tubular reactor with a copper catalyst contained in vertical tubes and boiling water on the shell side. The heat of methanol reaction is removed by partial evaporation of the boiler feedwater, thus generating 1—1.4 tons of MP steam per ton of methanol. Advantages of this reactor type are low byproduct formation due to almost isothermal reaction conditions, high heat of reaction recovery, and easy temperature control by regulating steam pressure. Tb avoid inert buildup in the loop, a purge is withdrawn from the recycle gas and is used as fuel for the reformer. 

The feed is desulfurized and mixed with process steam before entering the steam reformer. This steam reformer is a top-fired box type furnace with a cold outlet header system developed by Krupp Uhde. The reforming reaction occurs over a nickel catalyst. Outlet reformed gas is a mixture of H2, CO, C02 and residual methane. It...
