PRINCIPLES OF OIL EXTRACTIONBiogas

Methods of extraction There are basically three methods of removing oil from the raw materials: solvent extraction, wet processing or dry processing. Solvent extraction is not suitable for smallscale processing because of high capital and operating costs, the risk of fire and explosions from solvents and the complexity of the process.
