Title: EVALUATING BLACK POWDER FORMATION OF HYDROCARBON GAS FLOWED THROUGH PIPELINES
Abstract:
Sales gas output from a glycol dehydration unit in a gas plant is flown into a sales gas pipeline. One or more operational parameters of the glycol dehydration unit are received. One or both of an amount of glycol carryover and an amount of water carryover in sales gas output from the glycol dehydration unit in the gas plant are determined based on the one or more operational parameters of the glycol dehydration unit. An amount of glycol and water co-condensation in the sales gas pipeline is determined based on one or more operational parameters of the sales gas pipeline and the one or both of the amount of glycol carryover and the amount of water carryover. An amount of black powder formation of the sales gas is determined based on the amount of glycol and water co-condensation.
