Soap Stock Separation Process

Preparation of Biodiesel and Separation of Hemicellulose from Soap Skimmings

Soap skimmings are an intermediate substrate in the production of tall oil from Kraft pulping black liquor. In this study, biodiesel was produced directly from soap skimmings before being processed into tall oil using acetyl chloride and sulfuric acid as accelerators. The effects of the accelerator amount, reaction time, and pH on the production yield were investigated. The yields of biodiesel ...

Design of Optimal Process Flowsheet for Fractional Crystallization Separation Process

A procedure is presented that synthesizes fractional crystallization separation processes to obtain pure solids from multi-component solutions. The method includes a procedure to generate a network flow model to identify alternative process designs for fractional crystallization. The main advantage of this systematic procedure with respect to other reported procedures is using non-equilibri...

Lipase pre-hydrolysis enhance anaerobic biodigestion of soap stock from an oil refining industry.

A novel alcalophilic Staphylococcus haemolyticus strain with the lipolytic activity was used to perform enzymatic hydrolysis pretreatment of soap stock: a lipid rich solid waste from an oil refining industry. The culture liquid of the selected bacteria and an enzymatic preparation obtained by precipitation with ammonium sulphate from a filtrate of the same culture liquid were used for enzymatic...
