Design of Solvents for Palm Oil Recovery using Computer
In palm oil refinery process, bleaching earth is used in bleaching process. Used bleaching earth, also known as spent bleaching earth (SBE) is removed from the process as waste which contains some remaining oil. Many studies have been done to fully utilise the SBE before it is turned into waste. One of the known studies includes the extraction of remained palm oil from SBE. The extractions process is either using solvent or

Kraft process
The invention of the recovery boiler by G. H. Tomlinson in the early 1930s was a milestone in the advancement of the kraft process. It enabled the recovery and reuse of the inorganic pulping chemicals such that a kraft mill is a nearly closed-cycle process with respect to inorganic chemicals, apart from those used in the bleaching process.
