Techno-economic analysis of extraction-based separation

Feb 13, 2017 · Two different distillation systems (Fig. 1) were proposed to reduce the fuel requirements of purification of extractive processes. The distillation system used in each fermentation process depended on the condensation temperature of regeneration column, and the condenser or boiler temperature depended on column operation pressure.

Thermal Design of Economizer for Waste Heat Recovery

May 01, 2019 · The heat dissipated during this process is harnessed. A two pass water-tube boiler is used as waste heat recovery boiler (WHRB).In this boiler we install economizer for efficiency improvement. Waste heat recovery economizer uses waste flue gases for steam production which has wide range of variations in parameters.

4-1 Recovery Boiler Equipment and Operation

Recovery boilers consist of a water-walled furnace, where combustion of black liquor is completed followed by a series of heat traps where the hot combustion gases are cooled and superheated steam is generated. Slide 2 There are three key parameters that are considered in designing a recovery boiler: • heat input per plan area • furnace

energy efficiency in waste recovery boiler Agent

Waste heat recovery boiler 2 may include economizer (water heater) and/or air heater heating surfaces for efficiency improvement, but preferably does not have any superheater surfaces. The absence of superheater surfaces from the waste heat recovery boiler 2 allows more heat for the production of saturated steam.

Working with an extractive distillation process

The most important point, however, is that in the pure component mixture benzene is the low boiler, while in the mixture containing the solvent, it is the high boiler. This is the principle of extractive distillation where, at first, a close-boiling distillation cut is produced; this is then mixed with a polar solvent to increase boiling differences between components, thus increasing the relative volatility of the non …

The boiler feed water is assumed to be at 100 C with a specific enthalpy of 419 kJ/kg. From Fig. 11b, it is evident that when the base case (conventional process) emits one unit of CO2 (kg/s) to the environment, the improved process (DWC) emits much lower CO2, by 0.59.

Extractive Distillation | Scientific.Net. However, tetrahydrofuran will form a minimum boiling azeotrope with water, which has a boiling point of 63.4°C, so general distillation can not separate them. Common methods to solve this include extractive distillation, pressure swing distillation, azeotropic distillation, pervaporation and so on. Get A Quote
