In Chemical Process Industries process safety is of utmost importance. And, to address this a process engineer analyzes all the possible scenarios during plant designing. Any wrong design may lead to a possible plant accident. As a single big accident such as toxic gas leakage, plant fire or storage tank explosion can do irreversible damage […]
This is in continuation of my last article on the costing of shell & tube heat exchanger. In this article I will be sharing & discussing the excel sheet for distillation column cost estimation. This will give us clarity about the equipment cost which we can use as a basis to validate the various quotation

As a Chemical Process Engineer, we are suppose to do equipment costing to evaluate the equipment fabrication quotations received from various equipment fabricators. These equipment are like shell and tube heat exchangers, distillation columns, agitated vessels, jacketed vessels, decanters, storage tanks, etc. This equipment costing exercise gives us clarity about the equipment cost, which we

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

In Chemical Process Industries, we transfer gas or liquids from one point to another point. And, for this purpose we use pumps, fans, compressors and pipe lines accordingly. As a process engineer, we need to do the process calculations to estimate the power requirement, flow rates and pressure drop through this piping network. So, to

Orifice type flowmeters are widely used in our chemical process industries. The reason behind this, is their low cost, easy installation and maintenance. Fundamentally, an orifice meter provides volumetric flow rates of the fluid and by multiplying it with fluid density we can get mass flow rates. Orifice type flowmeters gives very accurate flow rates

In chemical process industries we use control valves to regulate the flow of fluids. This fluid can be liquid, gas or sometimes liquid slurry. We need control valves to control various parameters such as level, pressure, temperature, flow, feed ratio, etc. These control valves can be pneumatic or electric operated. In our industries, we use

For the successful and timely completion of a project, Project Cost Management is very critical. For a project manager, it is very important to estimate, budget and control the project cost efficiently. Any glitch in this process may lead to slowdown the overall progress of the project in the absence of fund. While, in some
