Description:

Most natural gas streams leaving the reservoir contain water vapor. In many cases, free water is also produced along with the natural gas. Natural gas cools as it travels up the well bore to the surface due to pressure reduction and conduction of heat through the pipe to cooler formation walls since the ability of gas to hold water vapor decreases as gas temperature decreases produced natural gas is nearly always saturated with water vapor when it reaches the surface. Additional cooling of saturated gas will cause free water to form. If the gas is further cooled, hydrates will form and serious equipment damage or flow restrictions will result. This is why it is so important to remove water vapor from natural gas. There are several methods for dehydrating natural gas which will be covered in this course?

Goal:

To enhance the participants’ knowledge, skills, and attitudes necessary to understand and use methods of dehydrating natural gas
