Abstract Information :
Methanol is used in the production of crude oil to prevent formation of gas hydrates. Residual methanol in crude oil can lead to costly problems in refinery operations, especially with wastewater treatment. Typically, direct-injection multidimensional gas chromatography is used to determine methanol in crude oil via ASTM D7059. Static headspace gas chromatography â€“ vacuum ultraviolet absorbance spectroscopy (SH GC-VUV) offers an attractive alternative to the complex hardware setup for ASTM D7059. A working concentration range of 5 to 1000 ppm can be achieved, with VUV spectral confirmation of methanol in crude oil. Headspace analysis eliminates the GC inlet and column lifetime problems associated with ASTM D7059.
