WebAssume there is an HTS reactor in the flowsheet and that mass balance will need to be calculated. Case 1. The inlet temperature is 320°C, and the outlet temperature is 394°C. The outlet composition (dry basis) reported by the laboratory was the following: H 2 = 74.86 % CH 4 = 4.16% CO = 3.38% CO 2 = 16.36% N 2 = 1.23%. WebTaking the mass balance of the tracer in the reactor gives: Recalling Vr / Q = τ, the above equation can be rewritten as (5.29) This is the mathematical description of perfectly-mixed flow model. The initial condition is Integrating Eq. (5.29) yields Rewritten as (5.30) Or From the definition of F ( t ), the above equation becomes (5.31) cigna health plan doctorsWebWe note that since the reactor is being filled, the volume, V, varies with time.
