2020 REFINING PROCESSES HANDBOOK PROCESS CATEGORIES COMPANY INDEX BIOFUELS Lurgi Biodiesel Oils and fats Application: Production of biodiesel [Fatty acid methyl ester (FAME)] Feedstock-Vegetable or animal oils and fats; major feedstock for fuel applications are rapeseed, soya, tallow or palm oil. Oils refining Description: Biodiesel is produced from triglycerides by transesterification with methanol under presence of an alkali catalyst (sodium methylate) at 60°C and atmospheric pressure. Key features of Lurgi`s biodiesel technology are maximum yield (1 kg feedstock = 1 kg biodiesel), closed-wash water loop (no wastewater from core process units) and sediment removal for palm and soya oil to remove sterol glucosides far below limits given by international quality standards. Only NaOH and HCl are used in the process. Any resulting sodium chloride ends up in the glycerin, can easily be removed and does not cause fouling or side reactions during further processing (see glycerin distillation). Products: Biodiesel meeting all international quality standards, including EN 14214 and AS™ D6751 Co-product: Crude glycerin (purity > 80%) Economics: CAPEX: $7 MM-$12 MM Utilities: Capacity: Standard capacities 100 tpd-1,100 tpd Installations: > 50 (since 2000) NaOH Methanol catalyst HCI Transesterification Glycerin water pretreatment and evaporation Washing and drying sediment removal Crude glycerin concentration > 80 % Biodiesel "ready-to-use" Licensor: Air Liquide Engineering & Construction Website: https://www.engineering-airliquide.com/lurgi-biodiesel Contact: oleo@airliquide.com Copyright © 2020 Gulf Energy Information.
