Dry acetylene techhnology 1. energy-saving, 2. lower energy consumption, environmental protection, safe
I. Brief Introduction
Dry acetylene technology,widely used in industry of calcium carbide process PVC and chlor-alkali chemical industry with so many benefits, such as energy-saving, lower energy consumption, environmental protection, safe, controlled reaction process, carbide mud residue as building materials and so on, is congruous with national policy of environmental protection. On 5th 2007, this technology is put into enterprise catalog of prevention and control of air pollution and technology catalog of environmental protection encouraged by State Environmental Protection Administration.
gaseous phase is 90-95°C,and solid phase temperature is 100-110°C, the reaction is brought away by the steam. The diameter of calcium carbide is less than 2mm, the hydrolysis rate is higher than 99%, and the acetylene yield rate is higher than 98.5%.
Safety, water-saving and high-efficiency dry acetylene technology uses 1.2 times water to hydrolyze calcium carbide powder, and produces water content 5%-8% calcium carbide dregs, water content of acetylene is 75%, reaction temperature
II. Environmental Benefits
1,Zero Discharge
The water needed is acetylene, not only to protect environment but also to recover dissolved acetylene.
2,Zero Dust Discharge
Closed process from crushing to discharging. If carbide mud residue is used for manufacturing cement, it can be carried into cement factory. If for bricks making, discharge moisture is adjusted free from dust.
3,Air Pollutant Discharge
0.02% of acetylene in the vapor from discharge machine
4,Solid Pollutant
Carbide mud residue is the material for cement making, and for other building materials.
III. Advantages and outlook
1.100,000 tons PVC use dry acetylene technology to reduce equipments and processing, also save land, power and water consumption, then can increase profit for about 60 million Yuan, with very remarkable economic benefits.
2. Zero release of waste water and gas of the dry acetylene technology are beneficial to the comprehensive use of calcium carbide dregs, to put an end to the waste solid pollution, and to protect the ecological, working environment essentially, with very significant social benefits.
3. with high safety system, and controllable reaction process.
4. It conforms to the national environmental and energy-saving policies.
