22. In Dry Cement Process Ensure minimum of in-leaking air is achieved, therefore maintaining correct pressure drop through pre heated tower Signal a possible explosion hazard due to high oxygen and carbon monoxide levels produced from process Copyright© 2014 Austin Analytics Group, LLC

23. High dust levels mean sampling is difficult; in situ method preferred Exit temperature from 1st stage 650-750°F Zirconia is ideal; accurate and stable so operator gets maximum through-put of product without endangering plant. Copyright© 2014 Austin Analytics Group, LLC

24. When tankers are loading and discharging crude oil they have to be blanketed with inert gas (CO 2 ). This gas has to have an O 2 content below 8% O 2 at below 8% is obtained from boiler exhaust The level of O 2 controls change over valve and is measured down- stream of the valve Below 8% feed to tanks Above 8% exhausted to funnel Copyright© 2014 Austin Analytics Group, LLC
