Introduction Different crude oil qualities in multiple intermediate storage and upgrade facilities Stronger regulations due to increased on-line production and longer transportation routes To meet market quality specifications: Blending with light hydrocarbons (diluent and butane) - 25 to 75 % 22nd Kazakhstan International Oil & Gas Conference 1 - 2 October 2014 3
Introduction • Amount of diluent has to be controlled for various reasons: • Excess of light hydrocarbons will cause cavitation / reduces life times of equipment • Emission of gaseous content needs to be minimized for environmental protection • Price of diluent components may exceed the price of crude oil 1 - 2 October 2014 22nd Kazakhstan International Oil & Gas Conference 4

BARTEC BENKE systems • The MGA-nano is designed for gas chromatography analysis of gases and low-boiling petrochemical liquids. • The analysis consists of determining the quality and quantity information on individual components of an unknown sample. • The key part of the analysis is the micro gas chromatography module (GC module for short) based on MEMS technology (micro-electro-mechanical system). • Every GC module is equipped with a specific separating column or separating column circuitry. • A powerful thermal conductivity detector (TCD) with very good detection limits is subsequently used to detect the separated components. • In order to expand the area of application of the MGAnano is equipped with a continuously operated evaporator unit. This allows low-boiling liquids to be evaporated at a preset temperature and under the controlled addition of a carrier gas. 1 - 2 October 2014 22nd Kazakhstan International Oil & Gas Conference 17
