Efficiency of kinetic energy recovery via hydroturbine in low-temperature methanol wash for methanol enrichment
Thread Content
The efficiency of the kinetic energy recovery process using a low-temperature methanol wash rich methanol hydraulic turbine is affected by gas desorption; therefore, it should not be driven solely by hydraulic forces, but also by expansion forces
Generate electricity using a methanol hydraulic turbine to recover the pressure potential energy of the rich methanol from the high-pressure area to the medium-pressure area
It only assists the motor in doing work, and the amount of methanol must be sufficient
An analytical solution does exist for the process of recovering potential energy using a methanol-rich turbine, but the effect of expansion work should be minimal. The first hydraulic turbine functions as an inverse of a centrifugal pump, and its structure differs from that of an expander (compared to centrifugal pumps); furthermore, the temperature of the second fluid (which is primarily related to its enthalpy value) changes little, almost not at all, so the conversion of heat into work is not significant； A hydraulic turbine makes use of the potential energy of the medium, and the gas that is generated also utilizes potential energy.
