Process Details: Reactor Feed Preheat/ Effluent Cooler. The Pre-heat exchanger's main purpose is to pre-heat the inlet feed from 181 o F to 266 o F. This is accomplished efficiently by pre-heating the feed in the tube side while simultaneously cooling the reactor effluent from 482 o F to 408 o F. The pre-heat temperature is selected based on previous research performed by a previous .
The hydrolysis reactor operation at these conditions is, however, a rather difficult task as the high pretreated lignocellulose loadings (> 5-10 % (w/w)) are connected to high apparent viscosities and poor mass transfer, result of which is a particularly slow hydrolysis rate and high energy expenditure.
