Which of the following is the purpose of pigging?

You can choose more than 1 answer.

• to transport raw natural gas

• to clean scale, and other debris from the pipe wall to keep the pipeline flow efficiency high

• to manage liquid accumulation and keep the pipe free of liquids

• to physically separate, or “batch,” the variety of hydrocarbons that are transported through the line

Answer explanation

ALL except to transport raw natural gas

What is the function of Gas Metering Station?

• to act as a vessel with sufficient buffer volume to store the largest slugs expected from the upstream system

• to separate the gas and liquid phases and also acts as a storage for the liquids (heavy condensates) temporarily

• to measure parameters such as gas pressure and temperature, gas quality and gas flow

• to bring down the temperature so as to remove the heavy component and moisture

Answer explanation

gas metering station = fiscal metering - to measure parameters such as gas pressure and temperature, gas quality and gas flow

What is the function of Slug Catcher?

• to act as a vessel with sufficient buffer volume to store the largest slugs expected from the upstream system

• to separate the gas and liquid phases and also acts as a storage for the liquids (heavy condensates) temporarily

• to measure parameters such as gas pressure and temperature, gas quality and gas flow

• to bring down the temperature so as to remove the heavy component and moisture

Answer explanation

to act as a vessel with sufficient buffer volume to store the largest slugs expected from the upstream system
