THE Transactions of the Society of Chemical Industry (58, No. 2; 1939) contain several papers presented last November to a meeting of the Chemical Engineering Group which dealt with the industrial ...

It is always recommended to allow a vacuum booster to cool down between running at maximum differential pressure and ultimate pressure. Maximum differential pressure occurs during the evacuation cycle ...

Refinery vacuum distillation units (VDUs) use ejector systems to establish and maintain distillation-column pressure for capturing valuable crude fractions and reducing vacuum residuum. Reliable ...

Distillation columns are extensively deployed in the chemical process industries when there is a need for separation of components that have different boiling points. Typically, a mixture of ...

In chemistry, solvents (generally in liquid form) are used to dissolve, suspend or extract other materials, typically without chemically altering either the solvent or the other materials. Solvents ...

Distribution characteristics of crude oils and crude oil fractions, as measured by ASTM D-2892, D-5236, D-86, D-2887, and D-1160, can be accurately described by Riazi's boiling point distribution ...
