F25J2200/00 - CPC Classification

Processes or apparatus using separation by rectification

• F25J2200/02 » in a single pressure main column system 516
• F25J2200/04 » in a dual pressure main column system 169
• F25J2200/08 » in a triple pressure main column system 37
• F25J2200/10 » in a quadruple, or more, column or pressure system 17
• F25J2200/20 » in an elevated pressure multiple column system wherein the lowest pressure column is at a pressure well above the minimum pressure needed to overcome pressure drop to reject the products to atmosphere 41
• F25J2200/30 » using a side column in a single pressure column system 83
• F25J2200/32 » using a side column fed by a stream from the high pressure column 20
• F25J2200/34 » using a side column fed by a stream from the low pressure column 26
• F25J2200/38 » using pre-separation or distributed distillation before a main column system, e.g. in a at least a double column system 35
• F25J2200/40 » Features relating to the provision of boil-up in the bottom of a column 107
• F25J2200/50 » using multiple (re-)boiler-condensers at different heights of the column 79
• F25J2200/70 » Refluxing the column with a condensed part of the feed stream, i.e. fractionator top is stripped or self-rectified 315
• F25J2200/72 » Refluxing the column with at least a part of the totally condensed overhead gas 126
• F25J2200/74 » Refluxing the column with at least a part of the partially condensed overhead gas 296
• F25J2200/76 » Refluxing the column with condensed overhead gas being cycled in a quasi-closed loop refrigeration cycle 160
• F25J2200/78 » Refluxing the column with a liquid stream originating from an upstream or downstream fractionator column 152
• F25J2200/80 » using integrated mass and heat exchange, i.e. non-adiabatic rectification in a reflux exchanger or dephlegmator 37
• F25J2200/90 » Details relating to column internals, e.g. structured packing, gas or liquid distribution 51
