Overview:

Project name: Qian'an JiuJiangCoking

Project location: Qian an city,Hebei

Investor: Qian’an JiuJiang Coal Transportation Co.Ltd.

Equipment selection: Three unit 9670kw steam LiBr absorption chiller

Main feature: Supply cooling to coking production process.

Introduction:

Qian'an JiuJiang Coal Transportation Co.,Ltd is affiliated to Qian'an JiuJiang Company, which is a large private  enterprise established in January1996, with 0.3 billion registered capital and 10 billion fixed assets. Qian'an JiuJiang Coal Transportation Co.,Ltd was established in February 2005. Based on present and look to the future,  Qian'an JiuJiang Coal Transportation Co.,Ltd provide large scale matching equipment for the highway wire rod  production which got 4 million ton annual output in 2007 and got 6 million ton annual output in 2007. It started new coking project (4*65 holes, 5m HXDK50-06) to produce 2 million ton coal in 2008.

When producing coke, high temp coke oven gas was produced, which contained a large number of high-valued by-products, such as coal tar,naphthalene. The high temp coke oven gas must be cooled stably, then the high-valued coal tar and naphthalene will be separated. So that the chiller's performance and stability should be high enough to meet the cooling temp. If not, it will cause decreased output of the high-valued coal tar and naphthalene and also the decreased quality of high temp coke oven gas. The coal tar and naphthalene, which was not separated  from the coke oven gas, will stick in the inner wall, and coagulation will be caused if the temp is lower, which will  cause the blocking of the running piping, then coagulation will be caused in the burner, which will damage the  burner. So the chiller’s stable operation and better performance are the decisive factors in coking process. Once  some  faults occur on the chiller, enormous economic loss will be caused for the user. AS 830*10 4kcal/h steam LiBr  absorption chiller, the customer has stricter demand for the chiller manufacture in machine's stability and performance.

Highlights:

Ultra-large chiller for coking process

The unit cooling capacity is 9670kw, with the layout of the absorber and evaporator left and right. A large number of  high efficient copper tubes have been adopted, the chiller's total weight is over 64 tons.
