Before breaking the pressure, the reactor effluent is preheated in the Catalytic Column Feed/Bottom Exchanger and then feeds the Catalytic Column.
The Catalytic Column is a reactive distillation column consisting of a succession of reaction and distillation modules called “doublets”. Each module is optimized to achieve the highest efficiency and a module is composed of a catalytic basket and three distillation trays.
Reaction is achieved in liquid phase in the up-flow mode. The Catalytic Column enables a high degree of isobutene conversion by removing the MTBE product through distillation as
it is formed in the “doublets”.
By contacting only the liquid phase in the catalytic bed section of each “doublet”, the catalyst utilization is greatly enhanced compared to contacting the catalyst bed with both the liquid and vapor phases. The liquid/vapor contact is re-established over the three fractionating trays below the catalytic basket. The MTBE product is washed down in the liquid phase as it is formed in the “doublets”, and more of the isobutene is transferred to the reactive liquid phase from the vapor phase raising to the column top. A small amount of methanol can be injected on flow control in the catalytic zone to maintain a methanol excess favoring the etherification reaction. The excess methanol in the catalytic column feed is lifted overhead as an azeotrope with the C4 hydrocarbons, which enables to fractionate the MTBE product with no methanol contamination.
The column pressure is maintained high enough to obtain the desirable operating temperature in the catalytic zone. Hence, towards the End Of Run conditions the column pressure is increased by 200 kPa, compared to the Start Of Run conditions, to increase the reaction temperature. The column overhead vapor is condensed in the Catalytic Column Condenser. The raffinate product and the excess methanol is removed overhead as
a subcooled distillate product. The column pressure is maintained using a hot vapor bypass control, and the column is reboiled using desuperheated high pressure steam in the thermosyphon.
A stripper is foreseen to remove the oxygenate compounds from the raffinate. Indeed, oxygenates such as methanol and TBA need to be reduced at minimum, because these compounds cause an increased fluorhydric acid consumption within the Alkylation unit.
The C4 raffinate is preheated in the DME Stripper Feed / Bottom Exchanger and then sent to the DME Stripper. To recover a maximum of methanol, wash water from unit 200 is injected on the overhead vapor of the DME stripper, prior to be partially condensed in the DME Stripper Overhead Condenser. Most of the DME is stripped of in vapor phase from the DME Stripper Reflux Drum. The methanol / water mixture is removed from the DME Stripper Reflux Drum boot under boot level control, and mixed with the
Raffinate Water Wash Column bottom to be sent to the alcohol / water distillation of the unit.
The DME Stripper bottom is cooled into the DME Stripper Feed / Bottom Exchanger and then in the Product Cooler down to be sent to the Adsorbers.
