Reduction of waste and conversion to the valuable products is the key challenge in today’s competitive petrochemical business. Large amounts of the carbon dioxide is treated as waste and vented to atmosphere from ethylene glycol plants. Carbon dioxide (CO2) is one of the byproducts produced during the manufacturing process of ethylene glycol. Carbon dioxide may be used as one of the raw material in urea and methanol plants. Moreover, CO2 can be liquefied up to a food grade product or can be utilized for dry ice, cold drinks, beverage preparation, or even as a preservative. This study will examine opportunities to reduce carbon dioxide emission to the atmosphere and utilization in eco-friendly manners by conversion into competitive petrochemical products. This study also describes technologies designed to recover and purify the waste carbon dioxide. The recovery and purification of waste CO2 will provide two benefits. First, a reduction in the large amount of CO2 vented to the atmosphere and the subsequent reduction of pollution and global warming which could be realized. Secondly, the availability of raw materials from waste stream, which will reducing the production cost.
