Mengxi lignite drying upgrading technology system is expected to put into operation this month

Recently, Hailar Mengxi Coal Co., Ltd. invested more than 20 million yuan to build a lignite drying project has entered the installation and commissioning stage, is expected to officially put into production in late December. This process has filled the gap in the city's coal industry.

Over the years, Hailaer Mengxi Coal Industry Co., Ltd. has adopted the principle of “high starting point, high efficiency, high recycling, and high safety protection”, combined with the coal reserves and geological structure characteristics of mines, continuously innovating technologies, and introducing advanced domestic equipment and processes. The current scale of mine construction is to produce 1.2 million tons of raw coal per year. In 2008, the company invested more than 20 million yuan to build a lignite drying and upgrading technology system, which has the advantages of less investment, quick effect, energy saving and environmental protection. After formal production, it can process 800,000 tons of lignite annually, increase the annual output value by 100 million yuan, pay taxes of 8.73 million yuan, and employ 22 people.

Acids exist universally in our life. There are both numerous kinds of natural ACID compounds with biological functions and massive synthesized acids which are used in many ways.

In industry

Acids are fundamental reagents in treating almost all processes in today's industry. In the chemical industry, acids react in neutralization reactions to produce salts. For example, nitric acid reacts with ammonia to produce ammonium nitrate, a fertilizer. Additionally, carboxylic acids can be esterified with alcohols, to produce esters. Acids are often used to remove rust and other corrosion from metals in a process known as pickling. They may be used as an electrolyte in a wet cell battery, such as sulfuric acid in a car battery. 

In food

Many acids can be found in various kinds of food as additives, as they alter their taste and serve as preservatives. Phosphoric acid, for example, is a component of cola drinks. Acetic acid is used in day-to-day life as vinegar. Citric Acid is used as a preservative in sauces and pickles. Certain acids are used as drugs. Acetylsalicylic acid (Aspirin) is used as a pain killer and for bringing down fevers.

Acid catalysis

Acids are used as catalysts in industrial and organic chemistry; for example, sulfuric acid is used in very large quantities in the alkylation process to produce gasoline. Some acids, such as sulfuric, phosphoric, and hydrochloric acids, also effect dehydration and condensation reactions. In biochemistry, many enzymes employ acid catalysis.
