To manage effluent generation and its treatment in Chemical manufacturing has been a major challenge for every chemical manufacturer. This challenge is becoming tougher and tougher day by day, as these effluents impact the environmental ecosystem adversely. And we all know environmental sustainability is the need of hour for every manufacturing industry. Therefore, this is […]

In our industries we can find the use of Liquid Jet Pumps in applications such as pumping and mixing of the fluids. These industries can be related with chemical, food or pharmaceutical area. We know Liquid Jet Pumps, as Jet Ejectors or Jet Eductors also. This device uses high pressure liquid as a motive force
Heat Exchangers are the equipment we use in chemical industries to exchange the heat between two fluid streams via indirect contact of the fluids. In this both the fluids remain separated by a heat conductive surface. And, heat transfer takes place from hot fluid stream to cold fluid stream. Generally, we use utilities for exchanging

In Chemical Process Industries during plant operation, we continuously generate huge volume of Data. The main sources of this data generation are plant control systems (DCS, PLCs, etc.), ERP system, QC/PC labs, Plant operation log books, etc. This data is very useful to understand the performance and correct decision making for plant operation and various

Six Sigma is a statistical tool for process improvement. This is a step-by-step systematic approach to solve the problems and we know it by DMAIC methodology also. In Six Sigma we convert real life problems into statistical problems. After converting we use statistical tools to find the statistical solutions for that problem. Afterwards, these statistical

The chilled water and chilled brine are cold utilities, which we use to remove heat at lower temperature levels than cooling water. We use these utilities in our chemical process industries (CPI) to remove heat from air-conditioning system, process equipment and fluid streams. From cooling water at supply temperature 32 0C, we can achieve cooling

In a distillery, we use two distillation columns in series for ethanol distillation from fermented wash. First column is Analyzer Column and second one is Rectifier Column. We get final product from top of the Rectifier Column, which is an azeotropic mixture of ethanol and water. This final product is also known by the name

As we know, in liquid-liquid extraction process we use solvent, to extract solute from the feed. If we technically see, extraction is the combination of two processes. First is mixing of feed and solvent, while second process is decantation, where phase separation takes place. The solvent and feed are immiscible liquids and forms two distinguished

In many chemical manufacturing processes ammonia is used as a raw material and generally feed in excess than theoretical requirement. And unconverted ammonia recovery is very important for the lower product cost and market competitiveness. In this type of process, we first absorb this unconverted ammonia in the absorber column it can be packed or

In chemical industries fluidized bed reactors are used for solid gas reaction. In this we use gases as a fluidizing media to fluidize the solid catalyst, which is a bed of finely divided solid particles. This fine powder is contained in a cylindrical vertical shell, having a grid at the bottom to support the catalyst
