By analysing the circulating water ingredients,the article discusses the availability of the liquid chlorine bactericidal in the circulating water system of the ammonia plant,which is at a high pH of 8 2~9 0 The dosing of isothiazolone(XF 990),steady chlorine dioxide(NKC 650)and quarternary amine salt(ZS 601)is also developed,and we have gained some experiences from using new methods and new medicines with efficient germ control
A profit analysis indicates that for a 300 MW power unit through the introduction of discrete optimization for a circulating water system,it is possible to achieve a reduction Of coal consumption by 0.5—0.7g/(kW·h).
Soft water circulation water system and the sewage circulation water system are changed to an integrated circulation water sys- tem using heat exchangers.
When it was applied in the cooling water system of a refinery with some leakage, the average corrosion rate was less than 0.075 mm/yr after more than one year operation.
Through the investigation and analysis on the corrosion situation of 5 ℃ water circulation system in the production of PVC by calcium carbide method,reasons for the corrosion failure were discussed as well as the influencing factors,and the corresponding protection methods were proposed.
The Technique Reform for Energy-saving in Water Circulation System of Xinya Medicine Industry Co-The First Item of "Energy Management Contract" in Shanghai
The optimal control of water circulation system and partly purification of circulated water to balance the water flowrate and stabilize the water quality are essential to achieve closed circulation of the scrubbing water from gas generation station.
It can reduce investment and operation cost by using this strong self-suction pump in water circulation system. Convenience for operation and maintenance,and economic benefits for the enterprises was provided at the same time.
The quality of the purified water satisfies the requirements set for circulating water system water, which allows converting to a closed cycle of use of the water.
In addition, the experiment indicates that this novel chiller is highly suitable for an air conditioning system with a low dehumidification requirement or a system with a large cycle flowrate and an industrial cooling water system.
About 70% of the copepods entering the cooling water system of a nuclear power plant on northeastern Long Island Sound (USA) are not returned to the Sound in the effluent.
In this paper, experimental apparatus with water circulation system is produced, and LDV measurement of the swirling flows is performed in order to clarify the mean velocities and turbulent quantity with higher accuracy.
