regarding the residual oil content in white flakes. Residual oil is continuously monitored and based on these values, the process parameters, in particular, extractor parameters, are adjusted to optimize yields. High residual oil content in white flakes correlates to a loss, whereas low oil content indicates excess energy consumption. Pollution from residual oil content in the wastewater is one of the serious environmental problems. Due to the rapid development of the palm oil industry in Malaysia, a large volume of palm oil mill effluent (POME) has been produced at the same time. Removal of residual oil from POME was carried out using solvent extraction process.

Solvent extraction using hexane is the primary method for recovery of oil from soybeans, although some mechanical extraction is still used. Process improvement in extraction plants has continued with increasing emphasis on energy efficiency, cost reduction, reducing hexane loss, quality of meal and oil, and increased capacity, driven by a six-fold increase in soybean production since 1950 and 1 Analysis of the Hexane Loss in a Vegetable Oil Extraction Unit Teresa Varandas Roque1, Maria Joana Neiva Correia1, Renato Carvalho2 1 Instituto Superior Técnico, Av.
