Is there a product that you have paid for to take away?

Yes, there is. It is —– liquid chlorine.

Liquid chlorine, that is, liquid chlorine, is a yellow-green liquid and is highly toxic , vaporizes into gas under normal pressure, can be seriously poisoned by inhalation to human body, has severe stimulating effect and corrosiveness, burns and explodes when mixed with other flammable gases under sunlight, is active in nature, and can be mixed with most simple substances (or compounds) ) react.

Since the end of June, the price of liquid chlorine in many places in my country has been negative again.

In early July 2022, the average price of liquid chlorine in the Shandong market was about -200 yuan/ton, and the low price once reached -600 yuan /Ton. That is to say, liquid chlorine manufacturers not only do not need money when selling liquid chlorine, but also give money to sellers. This phenomenon can’t help but confuse many people. In fact, this is not a rare phenomenon in the liquid chlorine market, as it happened in February this year.

In late October last year, the price of liquid chlorine had just reached a record high, with the highest price reaching 4,000 yuan/ton. At that time, due to factors such as the dual control policy, the prices of various chemicals soared. Just 4 months later, the price of liquid chlorine once fell to -200 yuan/ton, a drop of more than 4,200 yuan/ton. By July, the price of liquid chlorine once fell to -600 yuan/ton, with a cumulative drop of more than 4,600 yuan/ton.

The reason is that the sharp fluctuation of liquid chlorine price is directly related to its production process: liquid chlorine is a by-product of caustic soda production, that is, in While producing caustic soda, liquid chlorine will be produced. The more serious the caustic soda expansion of enterprises, the higher the operating load of caustic soda, the greater the supply of liquid chlorine, and the more prominent the contradiction between supply and demand in the market. In recent years, the rapid expansion of caustic soda production capacity has led to a substantial increase in liquid chlorine production capacity. Liquid chlorine itself is highly toxic and can be vaporized into gas under standard atmospheric pressure, which is severely irritating and corrosive to the human body. Liquid chlorine may burn and explode when mixed with other flammable gases. Therefore, liquid chlorine must be disposed of, and if it cannot be used in downstream production, it must be temporarily stored and requires special equipment for storage, which is very expensive. In addition, storage also has strict requirements on temperature, and cold insulation equipment is required. If the temperature is too high in summer, it will be more dangerous, and the storage pressure will be greater, so it needs to be disposed of in time.

However, the overall downstream consumption of liquid chlorine is relatively small, such as chloroacetic acid, methyl chloride, chlorinated paraffin, epichlorohydrin , textile, printing and dyeing, pesticide, cellulose, etc. These downstreams are currently in a relatively sluggish period, and the consumption is not enough to form a price support for liquid chlorine. Because of the high storage pressure, liquid chlorine manufacturers prefer to pay part of the money to clear the inventory of liquid chlorine. This is the negative price of liquid chlorine. main reason for the value.

It is worth mentioning that although chlorine gas is needed in the production process of isocyanate, due to the particularity of chlorine gas, usually isocyanate manufacturers Chlorine balance in the production process is achieved through oxyacid oxidation technology and hydrochloric acid electrolysis technology, and liquid chlorine is rarely purchased from the market, so the negative price of liquid chlorine will not reduce its production cost.
