Background In real life as a process engineer we face situations where we need to calculate the velocity distribution and film thickness of falling film outside of a circular tube. For example, falling film evaporator, falling film gas absorption, where a viscous fluid flows upwards through a small circular tube and after that it overflow […]

Background As a process engineers many time we are required to prepare a mathematical model for non-reacting liquid tank or vessel having various shape (cylindrical, conical, wedge shaped, etc.). So, we are going to develop the same, let’s begun with a vertical cylindrical vessel shown in below figure. Consider following parameters for this vessel Input

In chemical industries we apply insulation to reduce heat losses to the surrounding, which is the cost to product. You can see there are two components for total cost in insulation work. First is the cost of installation of the insulation. And, second is loss of profit due to energy loss from the insulation. Therefore,

Cooling towers are very important part of any chemical process industries. It supplies cooling water to Condensers, Coolers and Jackets of Reactors / Vessels to remove the heat. So, fundamentally cooling towers are direct contact type heat exchangers. In which hot water from plant returns to tower and comes in contact with the air. And,

This article is to understand the data analysis in chemical process improvement in chemical process industries. As, we all have witnessed industrial development from manual operation to fully automated controlled one. Plant operations and controls have gone under tremendous transformation since then. Mainly, we can categorize this transformation in four major heads as, Analog and
