MSMPR Crystallization equipment
Crystallization is a key purification technique for various sectors of the chemical process industries (CPI). Several approaches for industrial crystallization have evolved over time and highly specialized crystallizer designs have been developed, especially in long-established industries. Solution crystallization is an…
Zarko’s challenge
Every distillation engineer west of the River Neretva is familiar with the work of Professor Zarko Olujic. His distillation laboratory at the Technical University of Delft (The Netherlands; www.tudelft.nl) is one of the largest and best facilities in the history…
Improving Control Valve Performance
Improvements to the performance of basic, regulatory control systems have a great return on investment and are some of the least expensive control improvements to make [1]. Control valves have a major impact on control loop performance and, therefore, improvements…
Crossover Applications for the ASME-Bioprocessing Equipment Standard
Because the global chemical process industries (CPI) encompass so many varied industry segments — including the conversion of raw materials and intermediates into chemicals and petrochemicals, fats and oils, paints and coatings, food and beverages, the refining of petroleum, the…
Lessons in Feedstock Change
These days, there seem to be more reasons than ever to change feedstocks throughout the chemical process industries (CPI). Whether environmental, or more directly based on financial and market drivers, big benefits usually require big changes. This is especially true…
Industrial Insulation Systems: Material Selection Factors
Thermal insulation systems can provide several functions on piping and equipment in industrial facilities. Some of these are: reduction in energy loss, process control, personnel protection, emissions reduction, condensation, freeze protection, and noise reduction. In the chemical process industries (CPI),…
Fractionation Column: Pushing capacity limits
Starting around 1970, many new contacting devices became available for use in distillation, absorption and stripping columns. Those devices included high-performance random packings, structured packings, high-capacity structured packings, augmented crossflow trays, counterflow trays and cocurrent flow trays. At the request…
Recover Waste Heat From Fluegas
Adding an organic Rankine cycle system to generate power onsite can help operators optimize the overall economics of combustion-related systems and emissions controls The ever-increasing cost of fuel and relentless push for environmental responsibility are constant factors in the profitability…
Polymer-Based Piping Systems in the CPI
Polymeric piping systems have been used in well-defined segments of the chemical process industries (CPI) for decades. They have proven their sustainability to manage almost any chemical load up to temperatures of 100°C in the moderate pressure region ( p…
Counting On Process Analytical Technology
If the debate that culminated in passage of national healthcare reform in the U.S. is any indication of what is ahead for pharmaceutical manufacturers, they should ready themselves for battle. Implementation of the sweeping measure puts the onus on drugmakers…
