Oxygen Specific Power Consumption Comparison for Air Separation Units

Abstract

Technologies life cycles became shorter than before as a result of globalization and open market, which derived organizations to update their dated technologies. Without technologies updating, which based on Technological Forecasting (TF), organizations can not be dominant leaders in the open market and eventually they will lose their business. The main objective of this paper was to evaluate the air separation units by calculating the oxygen specific power, to find the most cost effective unit. The oxygen specific power used as a Key Performance Indicator (KPI) for the selected Air Separation Unit (ASU) technologies. The KPI for the updated Air Separation Unit was reviewed and the latest value selected as theoretical benchmark, which was 0.28Kw/Nm 3. At the practical part, the data collected to three air separation units ASU-31, ASU-51 and ASU-71. The results showed that the specific power gaps that used as the KPI's of ASU-31, ASU-51 and ASU-71 are 0.464Kw/Nm 3 , 0.639Kw/Nm 3 and 0.631Kw/Nm 3 respectively. The results showed that these gaps can be minimized by the recommendation suggested in this paper to reduce power consumption.

Comparative Evaluation of Cryogenic Air Separation Units from the Exergetic and Economic Points of View

“…In [20], schematics of air separations units are evaluated, which differ regarding (a) the kind of product compression (internal or external) and (b) the amount of produced gaseous oxygen. The specific power consumption varies between 0.464 and 0.639 kW/Nm 3 .…”

“…The article [1] shows the dependence of the ASU specific power on oxygen purity obtained by statistical analysis of the characteristics of the different models of air separation units [[7], [8], [9]]. The data on characteristics review of high-performance ASU are presented in Table 1.…”

Towards Methanol Economy: A Techno-environmental Assessment for a Bio-methanol OFMSW/Biomass/Carbon Capture-based Integrated Plant

“…A typical air separation unit plant produces the oxygen required for gasification, with a 85% purity by volume. Considering electricity (for the air compression) and thermal energy (for the air distillation) an environmental impact value in term of CO2-equivalent emission equal 282 kgCO2eq/tO2 to can be obtained [33], The environmental impact value for pure hydrogen production was considered for the case of water electrolysis using solar energy as a primary energy source [34]. This value is lower than CO2-equivalent emission producing pure hydrogen by natural gas, oil, coal, or other raw material, but also lower than impact by wind energy or geothermal energy.…”
