In 2002, Anhui Jinhe Industrial Co., ltd was established, by a merger of Wandong Jinrui, a chemical engineering company and two other companies (Anhui Jinhe Industrial Co., ltd). This company is located at NO.127 on the east street in Lai an County, Anhui Province. Through about 10 years of development, Anhui Jinhe Industrial Co.ltd has become a large specified chemical enterprise which has ''billions of Yuan in total assets and about3000 employees'' (The Brochure of Anhui Jinhe Industrial Co., ltd). This company insists on strengthening management and optimizing the structure of the products according to the market (Anhui Jinhe Industrial Co., ltd). Because of its proper strategy, the output and sales revenue have increased by a large margin. Even in 2008, a year which all of the companies suffered under the economic crisis, Anhui Jinhe Industrial Co., ltd earned ''1.45 billion Yuan'', which was ''0.39 billion more than its revenue in 2007'' (Financial Report Analysis, 2). This company now is able to produce ''25000 tons of ammonia ,150000 tons of urea, 2000 tons of foodstuff grade spice and essence ,1500 tons of additive agent for food, 100000 tons of nitric acid and 100000 tons of formaldehyde'' during one year (Anhui Jinhe Industrial Co., ltd). Because of its massive output and outstanding sales revenue, it contributes to the local tax revenue and also promotes the development of the local economy. What is more, this company has acquired a lot of business enterprise natural intelligence honors such as ''Model Unit'', ''Famous mark in Anhui Province'' and many other certificates for management (The Brochure of Anhui Jinhe Industrial Co., ltd).

The dominant products of this company can be divided into 3 parts: chemical fertilizer, food additive, and fundamental chemical industrial materials. Chemical fertilizer includes urea and ammonium bicarbonate. Food additive contains acesulfame potassium, natural maltol, ethyl maltol, and vanillin. Liquid ammonia, nitric acid, formaldehyde, acetaldehyde''melamine, industrial magnesium oxide, neopentyl glycol, and sodium formate are the fundamental chemical industrial materials this company produces(Sun).

The manufacturing process of the following products: ammonium bicarbonate, urea, nitric acid and melamine will be explained in detail. As ammonia is needed to produce all of the above, the first process is to synthesize ammonia. This company uses the Harbor ammonia process to synthesize ammonia (Sun). Hydrogen gas and nitrogen gas are the starting materials. Hydrogen gas ''is colorless, nonmetallic, and tasteless and it is highly combustible''. It is dangerous because ''if Hydrogen gas is mixed with Oxygen gas or Chlorine gas, there can be an explosion'' (Hydrogen Wiki). Nitrogen gas is also colorless, nonmetallic, and tasteless, but it is not combustible (Sun). In general, it is inactive thus it is safe. To synthesize ammonia, the reaction should be under ''200atm at 500'', using ferric oxide as catalyzer'' (Sun), by heating Nitrogen gas and Hydrogen gas together, and then ammonia is synthesized. The Chemical equation is:

N2 (g) + 3H2 (g) =2NH3 (g)

Ammonia gas is an alkaline gas which is extremely ''easily to be dissolved in water'' (Sun). ''It is colorless but is an irritant, and it is poisonous and this makes it very dangerous for people'' (Sun). The next step is to produce ammonium bicarbonate. Dissolve ammonia into water to make ammonia solution. ''Then put carbon dioxide into the solution, thus carbon dioxide reacts with it and the crystal of ammonium bicarbonate will be separated out''(Sun). The chemical equation of this reaction is

NH3+CO2+H2O=NH4HCO3

The following is the manufacturing process of Urea. Urea is synthesized by ammonia and carbon dioxide gas directly. Carbon dioxide is also a ''colorless, odorless, nonmetallic, and tasteless gas''. It is''not able to support combustion'' (Carbon dioxide, Wiki). To produce urea, the reaction occurs in a urea synthesis tower in which the temperature is between ''186~188'' and the pressure of about 200 atm'' (Introduction of the process of Urea, 6). This chemical equation can explain this manufacturing process:

2NH3 + CO2 = (NH2)2CO + H2O

Then, separate the liquid urea from the mixture of liquid and gas produced during the last process. ''Spray the liquid urea from a high place, which cools the liquid urea and solidifies it'' (Introduction of the process of Urea, 6). In this way, granular urea is made, and used as a fertilizer.

Urea is the raw material to produce melamine. Urea is a ''solid which can be dissolved in water easily'' (Sun). There are two different methods to produce the melamine.

The first one is high pressure liquid-phase method, in which the reaction occurs at 370-450'' and under the pressure of 7-10MPa. And the second one is catalyzed gas-phase method, in which the reaction takes place at 390'' and under a pressure that is less than 0.3MPa'' (Melamine, Wiki). This company uses the second method. The following is the chemical equation for this reaction:

6 (NH2)2CO = C3H6N6 + 6 NH3 + 3 CO2

In the manufacturing process of nitric acid, the first step is to mix the ammonia gas and the air, then the ''ammonia reacts with the oxygen gas in the air at 860'桱 (Introduction of the process of the nitric acid, 2), thus nitrogen dioxide and water are produced. Here is the representation of this reaction:

NH3 + O2 '' NO2 + H2O

Nitrogen dioxide is a ''reddish brown gas which is poisonous and an irritant'' (Nitric acid Wiki). The next process is dissolving nitrogen dioxide into water when oxygen is needed. In this way, nitric acid is produced. The chemical equation of this reaction is:

4NO2 + 2H2O + O2 = 4HNO3

The products introduced above play a crucial role in agriculture and industry. Ammonium bicarbonate is one of the chemical fertilizers that are widely used in agriculture. It provides nitrogen to the plants and crops. This compound can also be used in ''plastic industry and rubber industry'' (Ammonium bicarbonate Wiki). Urea is also a popular chemical fertilizer. Its function is similar to ammonium bicarbonate. Both of them provide nitrogen to the plants and crops, but urea is ''more stable than the former one'' (Sun). Melamine is used to ''produce melamine resin, a very durable thermosetting plastic which is widely used in kitchen utensils''. Melamine can also be used to produce ''melamine foam, a polymeric cleaning product'' which is very useful in our daily lives (Melamine Wiki). Nitric acid is also a useful chemical compound. It can be used to clean food and other dairy equipment as ''it is able to remove precipitated calcium and magnesium compounds'' (Nitric acid Wiki). Besides, it also plays a very important role in ''manufacturing explosives, perfume, drugs and dyes'' (Uses of Nitric Acid). The price of the ammonium bicarbonate is 640 Yuan per ton, the price of the urea is 1570 Yuan per ton, and the price of the melamine is 9600 Yuan per ton and the price of the nitric acid is 3243 Yuan per ton. They are all not very expensive (Sun).

To conclude, Anhui Jinhe Industrial Co., ltd is a company keeps moving. The output and sales revenue both increase yearly promising a bright future for the company. This company gives financial aids to those poor students to help them go on their further studies every year, contributing to the development of local education. However, as it is a chemical industrial company, it does have some bad effects on the environment. Anhui Jinhe Co., ltd is expected to pay more attention to reducing the air and water pollution.
