Anhui Chlor-Alkali Chemical Group boldly negated the heavy oil and hydrogen mixed combustion mode used by the company's caustic soda production line for horses, and carried out technological transformations. It used the new hydrogen-burning mode of venting, and in 2005 it created a profit of more than 2.5 million yuan.
The caustic soda process introduced by the chlor-alkali group with a total investment of 30 million yuan was formally put into use in July 2002. Due to the large number of chain protections of the heavy-oil blending combustion mode control system, the plant was frequently stopped and the capacity could not reach the target. . Every time you re-drive, the thermal shock caused by the large temperature difference affects the life of the equipment and the product quality is not stable enough. Insufficiently discharged black smoke causes local pollution.
To this end, the chlor-alkali group brainstormed to adopt the method of going global and learn from the success of the company's caustic combustion model. In April 2005, under the guidance of experts from Switzerland, a further investment of 450,000 yuan was made for technical rectification. The use of a large amount of vented hydrogen resources generated by the electrolysis process and the use of a new 100% hydrogen combustion model effectively solves the old difficulties of frequent stopping of equipment, deters sources of pollution, and enters a virtuous cycle of production. The rate of genuine products has changed from 95% to 99%. The new model no longer uses a lot of steam atomized heavy oil, and it can use 10 million cubic meters of hydrogen to ventilate throughout the year. As of now, it has saved more than 2 million yuan.
Sodium hydroxid,with the chemical formula NaOH, is commonly known as caustic soda. It is a strong alkali with strong corrosivity, generally in the form of flakes,pearls or lumps.Industrial grade Caustic Soda contains a small amount of sodium chloride and sodium carbonate, and is white translucent crystal.Its aqueous solution has an astringent and creamy feel.Sodium hydroxide is prone to deliquescent in the air, so solid sodium hydroxide is often used as a desiccant.It is very soluble in water and emits a lot of heat when dissolved. It`s also soluble in ethanol and glycerin.
Sodium hydroxide (NaOH) is extremely versatile. Used in the production of paper, soap, dyes, rayon, metal smelting, petroleum refining, cotton fabric finishing, coal tar product purification, and food processing, wood processing and machinery industries.
The product is a strongly alkaline substance which belong to 8 grade dangerous goods. with strongly irritating and corrosive, dust or smoke can irritate the eyes and respiratory tract, corrode the nasal septum, direct contact between the skin and eyes and NaOH can cause burns, and misuse can cause digestive tract burns, mucosal erosion, bleeding and shock.So it`s highly corrosive and requires the "corrosive item" mark.
