Corrosion in fertilizer industry - Part 1.1

Image
By

The fertilizer industry is as complex as any other industry in terms of corrosion.

Its corrosion issues begin from the storage area itself.

There are four major areas that need to be looked at from the corrosion point of view -

  1. Production
  2. Storage
  3. Transportation
  4. Field application

In the production stage, there are a few sub-steps.


The first step begins with desulphurization.

The motive is to remove the sulphur.

This sulphur is present in the feedstock, which is the raw material to make the hydrogen for ammonium.

The feedstock is petroleum and sulphur is an impurity. Along with this, there may be some produced water as well.

This petroleum is stored in tanks made of carbon steel.

It is transported to the process through carbon steel pipelines.

Carbon steel is said to have less severe corrosion due to elemental sulphur.

This corrosion due to elemental sulphur has mechanisms different from sulphidation and hydrogen sulphide corrosion.

What is a Corrosion Loop - PART 1 - CONCEPT

By
Corrosion loop is used to simplify inspection procedures in refining processes. Corrosion loop is defined as a group of components with common materials, processes, and operating parameters.  Source: Rachman, A. and Ratnayake, R.M.C. (2020), "Corrosion loop development of oil and gas piping system based on machine learning and group technology method", Journal of Quality in Maintenance Engineering, Vol. 26 No. 3, pp. 349-368. https://doi.org/10.1108/JQME-07-2018-0058 It is needed when the scenario has - 1. Complex process 2. Several variables such a materials of construction, process parameters, functions 3.

Electrochemical testing - part 3- What does an ammeter do?

By
 Electrochemical testing - 3 - Ammeter Poll Question WITH Answers: Description: Tafel polarization is a potentiodynamic test, where the potential is changed at a certain mV/time rate. The changes in the current flow occurring due to the potential change are measured using the ammeter. The ammeter is connected between the working electrode and the counter electrode. It is NOT connected to the reference electrode in any way .
