An analysis of used lubricant recycling unit in Turkey

ABSTRACT In chemical industries such as lube oil recycling units, stakeholders seek to continuously increase the productivity and profitability of the chemical processes to survive in the market. While scholars have investigated technological production options, recycling, and lube oil recycling flows, there is not enough study that evaluates the interplay between the production volume allocation and the recycled oil quality and quantity contingent upon the process temperature and pressure. The results based on a case study in the Kayalar Dorse production in Turkey show that by optimizing the chemical process mix, the volume of the lubricant oil can be increased by 20% at almost zero variable cost increase.
