Applied Catalysts is offering Catalytic Reactor Units for process intensification of Catalytic processes using their proprietary ACMC® activated carbon monolith catalyst technology.  These modular turn-key systems offer enhanced productivity, selectivity and lifetime for Hydrogenation and other catalytic chemistries.  Chemistry that is not equilibrium limited can be converted … [Read more...]

Miniature Membrane Separators and Separating Organic Solvents

10/25/2018 By R.C. Costello

  Introduction to Membrane Separators Zaiput Flow Technologies’ patented liquid‐liquid/liquid‐gas miniature membrane separators enable liquid extraction in flow chemistry‐based processes and provide a solution for typical batch‐based liquid extraction steps (i.e., slow settling time/separation of emulsions, elimination of the need to run batches at half capacity to … [Read more...]

Transesterification – Biodiesel Part 4

09/06/2018 By R.C. Costello

Transesterification

Overview The transesterification unit is designed to produce ASTM grade biodiesel by reacting low FFA oil or preesterified oils with excess methanol in the presence of a sodium methylate catalyst. Evaporator An oil drying system (Evaporator not shown) removes water and methanol after the esterification unit but prior to the transesterification system.  The recovered … [Read more...]

What is the Future of the Nelson-Farrar Cost Indexes?

05/10/2018 By Richard Potts

The Nelson-Farrar Cost Indexes       The Nelson-Farrar Cost Indexes were started by Dr. W. L. Nelson and Dr. Gerald L. Farrar. The indexes were calculated and published in every issue each month by the Oil & Gas Journal and with quarterly summaries in the January, April, July, and October issues. The indexes were originally named the Nelson Cost … [Read more...]

CHEMCAD Dynamics for Operator Training

08/25/2017 By R.C. Costello

CHEMCAD Dynamics is a remarkable tool for operator training. The example shown is a distillation column that looks like a Piping & Instrument Diagram. Each control loop can be modified by changing the proportion, integral and derivative values. The model responds similarly to a plant distillation column. Liquid holdup in the column, heat exchangers and even piping can … [Read more...]
