WE SELL CHEMCAD SIMULATION SOFTWARE REQUEST A FREE DEMO

I wanted to reach out to see if you or anyone you know might be interested in receiving a free quote for ChemCAD, our comprehensive chemical process simulation software. ChemCAD is designed to streamline process design, optimization, and analysis, helping engineers achieve greater efficiency and accuracy in their projects.

If this is something that could benefit your team, I would be happy to prepare a quote or provide additional information about the software’s features and capabilities as well as a 2-week free trial and 8 hour free training .
Please let me know if you would like me to send over more details or arrange a brief discussion with Rocky Costello. Rocky is unlike anyone who sells this type of software as he has been using this for many decades and has the hands on experience in his successful company.

Thank you and I look forward to hearing from you.

"Scaleup of Chemical and Pharmaceutical Plants"
This article will discuss the scaleup of chemical and pharmaceutical plants.

Introduction

The blog will discuss only small continuous processes in the chemical industry and flow chemistry (continuous) processes in the pharmaceutical industries.

COSTELLO gets involved when the laboratory chemistry has been completed and the client is ready to consider a continuous process. Moreover, we get involved at the bench scale level or pilot level as well.

Degumming of Feedstocks – Part 2

The Degumming of biodiesel feedstocks process is necessary prior to the esterification and transesterification processes. Typical crude degummed oils have had their Hydratable Phospholipids (HPLs) removed by a simple water wash process. We typically accomplish this at the crushers facility. However, a typical soybean oil contains both hydratable and non-hydratable phospholipids (NPL’s). The water wash process does not remove these NPLs and they remain in the oil. The typical concentration of NPLs in water degummed oil is 200 ppm.
