Choosing the right type of construction material for the vessel and its components is the key to achieving a high service life of the equipment. At MACH, we can custom fabricate internals to meet the demands of your process. During the maintenance period of one of the vent scrubbers, MACH proposed to replace Monel Internals … Continue reading “CHOOSING THE RIGHT MATERIAL OF CONSTRUCTION TO AVOID DOWNTIME”


Carbon Dioxide (CO2), one of the universal industrial gases, is mainly produced during the combustion of hydrocarbons also known as fossil fuels. Due to a growing demand for CO2 as a commercial product, it is captured and purified, for transport and beneficial uses at other locations. Among many different uses, refrigeration, and cooling, the casting … Continue reading “CARBON DIOXIDE RELATED APPLICATIONS”


Recently an article was published by Tracey Reeves at John Hopkins University titled, “Flaw Found in water treatment method”. His article got my utmost attention as I currently work for an engineering company that designs separation units concerning many wastewater treatment applications. To design a complete process, we are presented with a list of contaminants … Continue reading “ACHIEVING IMPROVED WATER QUALITY FROM A WASTEWATER TREATMENT PLANT (WWTP)”


In a chemical process industry, the skill of troubleshooting can be mastered through critically analyzing plant and field operations, understanding the relationship between the process and its equipment, and having in-depth knowledge of engineering fundamentals. Consider Troubleshooting as a Programming Loop Troubleshooting can be thought of as a programming loop where the server, i.e. engineer, … Continue reading “TROUBLESHOOTING: A Complex Programming Loop”


WATER AND WASTEWATER TREATMENT Just like fresh air, water is an essential resource for the survival of humans and animals. Water constitutes 70% of the Earth surface but less than one percent can be classified as an accessible freshwater resource. Therefore, water is considered to be a scarce and most valuable resource in many regions … Continue reading “OUR SHARE TOWARDS A GREENER ENVIRONMENT”


DESIGN ASPECTS OF LIQUID DISTRIBUTOR In this section, we will discuss the parameters that need to be considered while designing a high-performance liquid distributor. Drip Point Density: The drip point density is the specific number of final distribution points per m2 of cross section area on top of the packing bed. For systems in contact … Continue reading "LIQUID DISTRIBUTOR – AN IMPORTANT TOWER INTERNAL (PART2)"

Liquid distributors provide adequate distribution of the liquid onto the packed bed and structured packing. To achieve an intensive mass transfer between the phases, liquid should be distributed equally across the column area. It serves to overcome maldistribution and, poor initial distribution can only be compensated to a limited degree by a larger bed height … Continue reading "LIQUID DISTRIBUTOR – AN IMPORTANT TOWER INTERNAL (PART 1)"

Scrubbers are a reliable means of removing fine particles from the gas stream through absorption. Scrubbers can be classified as dry or wet. Wet chemical scrubbers filter dust by introducing the polluted air stream with water droplets. There exist various wet impingement configurations, such as spray nozzles, misters, cyclonic, venture dispersion and others, to capture … Continue reading "Are You Getting The Most Out of Your Scrubber?"

Many important unit operations such as distillation, stripping and scrubbing rely on the proper selection of tower internals and packings for best separation. Tower packing creates a large amount of surface area to volume where the liquid-vapor mass transfer can occur. Furthermore, it increases the production capacity and the separation efficiency, lowers the pressure drop … Continue reading "Evolution in Random Tower Packings"
