Membrane modules and operation

The MRT Purifier, developed for Tecnimont-KT in the framework of FISR project, has been designed to house five membrane modules and operate at 450°C and up to 25 barg. Each module consists of two double sided, planar 30 cm X 12 cm membrane panels welded in series. Each panel has a palladium (Pd) alloy active membrane area of 0.03 m per side for a total installed membrane area of 0.6 m in the purifier. The modules are housed in a rectangular core which, along with the inlet distributor, promotes uniform reformate flow across the membrane modules. The core assembly (Fig. 3.11) is housed inside a pressure vessel. 

Continuing advances in development of new membranes with better thermal, chemical, and improved transport properties have led to many new possible applications. Development of newer membrane modules and operating procedures in recent years has provided a key stimulus for the growth of the membrane industry such as submerged membrane filtration for treating municipal water.
