Membrane-based unit operations have in recent years emerged as a sustainable and cost-effective means for treating surface water, seawater and waste water to meet water quality specifications desired by the industry. It helps in achieving regulatory compliance and water conservation with a smaller footprint compared to conventional systems.
Nalco 3D Trasar Technology helps in “performance management” of the membranes by mapping the
system stresses in real time on a 24X7 basis, and making proactive adjustments to the treatment
chemistry.

Cooling towers play a very important role in process industry. Cooling towers are
used to transfer process waste heat to the atmosphere, thus keeping the process
under control. Proper maintenance of cooling tower ensures trouble-free running of the process plant. This article highlights the various aspects and the importance of maintenance of cooling towers.

Distillation columns are one of the most critical components in petroleum refineries, gas processing installations and chemical plants. Defective columns may adversely affect plant operation and hence the quality of the product. In most cases, troubleshooting to pinpoint the cause of the problem in columns is conducted on-line, enabling continuous monitoring and assessment of the component.
Gamma-ray scanning is a convenient, cost-effective, fast, efficient and non-intrusive technique to examine inner details of a distillation column, while it is in operation. This article describes the features, procedure and applications of gamma ray scanning.

One of the major contributors to climate change is due to greenhouse gases. The
consequences of accelerated climate change, as predicted by scientists, could be disastrous for planet earth. Therefore, all industries including chemical industries, are duty bound to reduce or even avoid such emissions. The Clean Development Mechanism
(CDM) that resulted from the Kyoto Protocol has established a frame work to facilitate emission reduction through emissions trading. This article explains the CDM mechanism and the opportunities for various industry segments to monetise the emission reductions they achieve through this.

Infrared and Raman spectroscopy are powerful and complementary techniques of chemical and structural analysis. Over the past few decades these techniques have spread to virtually every field, that needs characterization, qualitative and quantitative details or structural or polymorphic features of materials. The immense versatility and adaptability of the modern instruments, accessories and software have enabled these techniques to be adapted to widest range of applications from truly online to off-line, industrial and research laboratories and on field testing with portable systems. Besides proven capabilities for characterization of compounds, the techniques can be applied online for process applications in chemical industries.

Temperature seconds pressure, the most measured variable in process industries. Reliable, economical, and accurate temperature measurements are essential to ensure safety of pressure vessels as increasing temp decreases their working pressure limits. In some applications e.g. reformer, boiler superheater tubes and electrical motor windings temp is so critical that 10OC rise above prescribed maximum limits, reduces their life expectancies by 50%. In addition optimum chemical reactions yield desired quality products economically and catalysts perform optimally for specified life spans at correct process temp only.
Read on to get full information on different temp measuring systems to select the most reliable one for your applications to maximize plant safety and productivity. Case Studies illustrate the precautions necessary to maximize temp systems reliabilities and innovations applied to overcome crises.
