6. Calculate the hydrate formation temperature of a 0.6 gravity gas at 1,500 psi. What technique would you use for a more accurate answer? . If hydrate formation were a concern, what would you do? 7. Gas with a 0.7 gravity exits the first stage of separation downstream of the wellhead at 120 F & 2,000 psi. You need to drop the pressure as it enters a 1,000 psi sales gas line. Is hydrate formation a concern? 8. How far may a 0.7 gravity gas at 3,000 psi and 100 F be expanded without hydrate formation? 9. How far may a 0.7 gravity gas at 2,000 psi and 150 F be expanded without hydrate formation
