Issue of synthetic yield
Thread Content
Let’s come out and discuss a few issues: what is the synthesis pressure in your methanol plants? What is the temperature of the catalyst bed? What is the airspeed? What is the circulation ratio? The catalyst from that manufacturer? That tower-type synthesizer? What is the yield based on phenol? What is the net value of the alcohol? How much are the inert impurities in the synthetic cycle gas?
Synthesis pressure: 4.5 MPa, catalyst bed temperature: 230–260°C; space velocity: 640,000 m3; recycle ratio: 5; catalyst: C307; synthesis tower shell and tube design； Yield? Net alcohol content 6% ； Inertness in synthetic cycle gas: 17%
