ICI-AMV process with Fe-Co catalyst

The ICI-AMV process was developed by the ICI Company for its 74-1 Fe-Co catalyst, where the process was designed by ICI and the engineering was designed by Uhde Company, Germany. The core of the synthesis loop at low-pressure is the radial-flow converter with three beds of catalysts using 74-1 catalyst of small-particle and indirect interchanger, and in series an inverted U-shaped waste heat boiler. The process flow is shown in Fig. 9.5. The main technical parameters are shown in Table 9.2. 

AMV adopted a part of the advanced technology of Kellogg and Brown processes. 

To enhance the output of high pressure steam produced by the waste heat boiler, the Uhde Company also proposed a sjmthesis loop with two converters and two waste heat boilers (Fig. 9.6) which were applied in the process with residual oil as raw materials and the cryogenic purification. The loop pressure is 16 MPa, the first converter has two beds, inter-cooled, radial-flow, and the outlet temperature of syngas is 473°C. The outlet gas goes through the waste heat boiler to by-produce high pressure steam then enters the second converter.
