Reformer and Membrane module

Due to these main reasons, new configurations called Staged Membrane Reactor (SMR) or Reformer and Membrane Modules (RMMs) have been proposed in the teehnieal literature [25-29].

Recently, a reformer and membrane modules (RMM) test plant having the capacity of 20 Nm /h of hydrogen has been designed and constructed by Tecnimont KT near Chieti, in Italy. This plant is described in Chap. 10 of this... 

In order to avoid the conflict of catalyst and membrane operating parameters, the selective membrane can be placed outside the reactor, in proper units located downstream. This is the concept of Reformer and Membrane Modules (RMM) steam reforming plant [3, 6, 16], shown in Fig. 5.9.

Hydrogen selective membrane is assembled in separation modules applied downstream to reaction units. The process scheme, called reformer and membrane module (RMM), is composed by a series of reaction-separation modules [7,8].

Sample connections, together with pressure, temperature and flow measurement points, are located at the inlet and outlet of the reformer and membrane modules to measure the performance of the RMM. A multipoint thermocouple is installed inside the first reformer tube in order to monitor the axial temperature profile along the heated catalyst length while two glass peepholes allow the reformer tube metal temperature to be measured by an infrared pyrometer. The control room is located in a safety area with a bird s eye view of the plant area. 

To evaluate RMM performance regarding methane conversion and hydrogen recovery, it is necessary to measure the content of the output stream from the reformer and membrane modules. The composition of the reformed gas and retentate streams was detected by an ABB analyzer. CHi, CO and CO2 concentrations were measured by the online non-dispersive infrared (NDIR) multiple analyzer, ABB URAS14. H2 was analyzed using the thermal conductivity detector ABB Caldos 17. A Perkin Ehner Gas Chromatographer unit (CLARUS 500) was used to analyze the composition of the permeate streams.
