Oil Separation

Oil Separation

Oil Separation

(OP)
Guys,

can we assume that the gas we got from 2-phase oil separator (crude oil with 0.5 water content on inlet) contents water vapors at the dew point?

RE: Oil Separation

By the time the crude oil, gas and water comes from the wells, mixes in the pipeline, equilibrium is a valid assumption.

RE: Oil Separation

(OP)
Ok, and what you think is the substance which will be dropped out at first after the start decreasing of temperature. This must be a mixture of different hydrocarbons and water? Isn't it?

RE: Oil Separation

Yes, the gas will be at both its water and hydrocarbon dewpoint.  If you cool it, at the same pressure, you form liquid.  If you also drop the pressure, you likely will still get liquid but it depends on the phase envelope.
