Methanol production FPSO plant concept using multiple microchannel unit operations

Development of a Microrectification Apparatus for Analytical and Preparative Applications

“…With a value of H = 12.7 cm, the determined HETP value of 1.27 cm is in good agreement with the literature [23]. Between this value and the 0.83 cm otherwise reported [36] lies a discrepancy that most likely originates from Eq. (10) or the data used for the calculation of the HETP value.…”

“…Following a proposal of Tonkovich et al [36], a MeOH distillation unit, for example, should be dimensioned according to the model of Silva et al [35] consisting of a set of six 1-m-high distillation units. Distillation should be carried out under pressure so as to facilitate the thermal integration of a distillation unit in a MeOH production plant from natural gas in off-shore regions.…”

An Integrated Design Method for Rotating Packed Beds for Distillation

“…Since 28 m³ of the vessel (Tonkovich et al, 2007) are provided for the distillation section, the application of rotating packed beds for the floating methanol process seems to be feasible. To further reduce the demanding space, more than two rotors may be arranged onto a single shaft into a single casing.…”

“…The natural gas is converted to reformed gas and synthesized to methanol and water. The subsequent step is the distillation of the water-methanol mixture to remove the water and to ship only the desired product methanol (Tonkovich et al, 2007). Such a process requires compact and stable apparatuses that are insensitive to movement, that is true for RPBs due to its high centrifugal forces.…”

“…In this case study the distillation within the process is investigated. Tonkovich et al (2007) published a theoretical study of a floating methanol process utilizing micro channel unit operations. Their specifications for the distillation have been used.…”
