This article is about understanding the process of a molten salt heating system. Before this let us discuss different types of heating systems, which we use in our chemical industries. In our chemical plants, we need to heat exchange at various temperature levels. These temperature levels can be low, in the range of 50 – […]

You can see in many processes; we use thermic fluid to maintain the reaction temperature. In reactor jacket or coil thermic fluid circulates to maintain required temperature conditions. For, efficient reactor operation automation and controls of the reactor is very important. Moreover, same thermic fluid system you can use for reactor heating & cooling requirements

In chemical process industries we use Fired Heater or Furnace to supply the heat at higher temperature levels. When I say high level, it means around greater than 500 0C. As we know other sources of heat supply are boiler, thermic fluid heater and molten salt heating systems. Out of these boiler and thermic fluid

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 many chemical manufacturing processes, ammonia is used as a reactant and generally we feed it in excess than theoretical required. After reaction part of the ammonia reacts and unconverted ammonia comes out from the reactor with product. For the economic feasibility and moreover environmental pollution abatement we need to recover this unconverted ammonia. Therefore,

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

In chemical industries raw materials enter into reactor and reaction takes place to convert them into products. These reactions can be either catalytic or non-catalytic. Reactor temperature and pressure depend on the reaction conditions. In chemical plants some reactions occur at low temperatures, it can be as low as ambient temperature. While some occurs at
In my 21 years of experience, I took lots of interviews. It includes the interviews for direct and campus recruitments. During interview I found there were many candidates who could have been cleared the interview. However, due lack of proper preparation they couldn’t make it. Therefore, based on my experience in this article I am

We can find batch distillation column in almost every chemical process industry. Specially, you can find it more in fine chemicals, specialty chemicals, pharmaceutical and small-scale chemicals production industries. This is so because, batch distillation column requires lower fixed cost and provide higher operational flexibilities. However, batch distillation columns consume more energy than a continuous

Boilers are the source of energy in form of steam, electricity or both for industries. They supply steam for various heating requirements of the plant. Moreover, provide electricity to drive motors and lightening requirements, which we generate using steam turbines. Therefore, boiler efficiency directly related to cost of steam and electricity. In industries we generally
