Detecting Chlorine Leakage With Aqueous Ammonia.

In most factory that use a cooling water system or water treatment facility, we often use chlorine gas as disinfection. Due to that, we often detect the leakage of chlorine in a pipe line, but it’s hard to detect because of the gas is not visible, only the smell we can detect.

General Process of Urea Production

Based on previous posting that we discuss about the general process of ammonia production, and now we have ammonia. But what can we do with it? One option is to convert it to urea. And another option is to export the ammonia to have a higher benefit than if we export the urea.... He..he..he... Just kidding boss... If we do that, so no body called or plant a fertilizer plant :)
Back to the topic...Urea is an interesting substance. It is an organic chemical, which is also produced in the human body to dispose of nitrogen. It is also the chemical which proved wrong the common belief in the 18th century, that organic substances cannot be created from inorganic raw materials. In 1828, Friedrich Wöhler was the first to synthesize urea from inorganic compounds. At the end of the 19th century, a method was discovered to synthesize urea from ammonia and carbon dioxide. This process is still the basis for modern urea production.

General Process of Ammonia Production

I will lead you through the basics of ammonia and fertilizer production. It will tell you not only how ammonia and its derivatives are produced, but will also tell the tale of the downfall of a large fertilizer site as a result of the highly volatile ammonia and fertilizer market. Finally we'll make a trip to the future and explore the possibilities of a 30+ year old chemical plant. This post will give you some basic information about fertilizer and describes the ammonia production process. So here we are... Let's start going...

A short story about Fertilizer Process Production.

Well… Now i want to tell a short story about fertilizer process production. In order to make a fertilizer, in this case urea. we need a raw material. The most important raw material are natural gas, water, and the air. In the block diagram below we can see unit integration on fertilizer plant.
