At the time of increased sustainability concerns posing the oil and gas production and refining industry, the concept of successfully manipulating and mobilising gases becomes imperative.
Apart from the conventional use of adsorptions and absorption for carbon di oxide, the use of membranes to separate the tase is facing higher speculation. Membranes are versatile, have a longer life and spare the continuous operational effort as required for the other technologies.
The applications of such membranes range all the way from upstream to midstream and occasionally downstream industries.
One specific midstream application was observed in Colorado, where an operator wished to reduce the carbon dioxide concentrations. Schlumberger oil services advised the company to use Apura membranes for the project. Apura membranes are designed by Schlumberger to work with high pressure and low concentration mediums. The apparatus was specifically designed to isolate the hydraocarbon gases from other imports such as carbon dioxide,
The company replaced their existing membrane separators with the Apura ones provided by Schlumberger. One major advantage observed was the ability to handle larger capacities of gases. The feed capacity increased by 25%.
Moreover, the initial carbon dioxide concentration was reduced from 3% to 2.3% on a flow rate of 227,000 m3/day
