Test on preparation of associated petroleum gas

At the invitation of one of the producing companies a test installation based on a specially developed material “E-CO” was tested

Brief characteristics of the test installation: main type installation for breaking emulsions “Cribrol MG”. Gas treatment capacity – 50 m³/h. Drainage discharge – manual. Media interface separation level is defined visually through observation windows when the volume of separated moisture reaches 4.6 liters.

Place of test: the Komi Republic.

Mounting site: gas pipeline after inlet separators and before preheater. Rated consumption of gas in the preheat furnace is 85 m³/h, the pressure on burners is 0.7 kgf/cm². Gas pressure before the test unit is monitored by a pressure gauge of the gas pipeline, gas pressure after the test unit is monitored by an inlet pressure gauge of the furnace. Pressure in both gauges before mounting equals to 6.8 kgf/cm².

Wednesday: APG. Medium temperature: 32-50 °C. Operating pressure: 6.8 kgf/cm².

Purpose of test: to demonstrate an ability of the installation to separate moisture, suspended particles and liquid petroleum fractions from gas, lack of the growth dynamics of the filter element’s resistance (the difference in the pressure gauge data before and after the installation).

12:45 Starting of furnace with the gas flow passing through the installation.
18.45 Stopping of furnace.
6 hours of operation

Visual observations: Pressure on the furnace burners is 0.1 kgf/cm², which is about 1/7 of the rated consumption of the furnace, i.e. gas flow rate equals to 10-12 m³/h. Growth dynamics of filter element’s resistance has not been noticed. After 6 hours of operation filtered cloudy emulsion of dark pale yellow color with a faint odor of petroleum product in volume of 1.25 liters was emptied to a transparent container, what made 17.3-20.8 grams per 1 m³ of gas. After 15 hours of settling emulsion changed color to a light gray, became more transparent, weak iridescent film formed on its surface. Sediment that consisted of fine dark brown solids that had been carried by water droplets out of the filter element’s body (self-cleaning effect) was formed at the settling zone of the housing.

By the results of test there was signed a protocol.
