Methanol Injection Inline Gasheater
Methanol Injection Inline Gasheater
(OP)
We are trying to take out of service an inline gas heater to our plant for a really overdue inspection without shutting down the plant. We tried injecting methanol to prevent the freezing of control valves etc but to no avail.
Does anyone have suggestions - maybe we didn't inject enough, what calc would you use?
Incoming natural gas is about 7900 KPA (1150 PSI) at a controllable max flowrate during servicing of about 120 m3/min with our peak being above 600 m3/min although we should be able to negate the high flows.
Reduced to 1714 (250 PSI)
Second reduction to 354 (50 PSI)
Is there something else injected to prevent freezing? Does anyone know a better calculation to predict methanol amounts? We were just injecting before the first let down - maybe we should inject after? Any suggestions would be appreciated.
Thanks

You can rent portable heaters of the size you own.
