Turboexpander for expansion condensate gas
Turboexpander for expansion condensate gas
(OP)
Hi
After the first mechanical separation I want to use turboexpanders for expansion natural gas in LTS (Low Temp. Separation). This is condensate gas (even C35+ are present). During expansion higher HC will condensate inside turboexpander. Can HC droplets cause damage? If it's no problem I want to ask for any information/links about manufacturers (turboexpanders).

Using turboexpander assembly for gas dew-pointing is well established practice. Sometimes it is the only feasible solution - for example, when gas pressure is above cricondenbar, mechanical refrigeration cannot be applied.
Two-phase fluid in turboexpander outlet is not a matter for concern: actually it is requirement in all cases when you need to knock out heavier hydrocarbons from sales gas stream.

If you want more than 15%, just expect to replace the rotating elements more often.
