Solar collector water heating system use solar thermal energy to provide hot for domestic and industrial use. These systems are operated either as open-loop or closed-loop flow circuit. The former loop not recommended the cold climates having freezing problem. Although previous studies on collectors have used operation with working fluid. However, it must high boiling low points colder regions ...

The basic need of living things that is very important and cannot be separated water. Various industrial activities require water for processing such as the palm oil industry, industry required to use with good conditions proper chemical treatment. power plant at PT. Socfindo Seunagan, requires steam needs from boiler. Boiler a closed place produce heating boiler system, among others, consists ...

An indirect, sensitive and accurate method for the determination of trace amounts of hydrazine is described. In this proposed the spectrophotometric method is based on its reduction properties of hydrazine with a known concentration of potassium permanganate to reduce the colour. The absorbance of unreduced permanganate is measured the colour difference at different wavelengths 546 and 526 nm w...

Hydrazine in water samples is determined by constant current chronopotentiometry in porous carbon electrodes. Hydrazine in alkaline solutions is oxidised to nitrogen in the pores of the electrode by constant current. Two types of electrodes made of reticulated vitreous carbon (RVC) were used, one fabricated from crushed RVC particles, the other with the original RVC material of 100 ppi porosity...

Thousands of medium and low steam boilers hot water operate in the country's industry, municipal energy agriculture. Their reliable operation is largely determined by maintenance a rational water-chemical regime. The main problems source are presence dissolved oxygen, iron ions, salts calcium, magnesium.
 aim work to analyze existing technologies equipment for treatment different types boi...

The required steam for steam-assisted gravity drainage (SAGD) oil sands operations is generated using a once-through generator (OTSG) that fed with relatively poor quality process water. Industries have reported possible solid particle erosion-related failure in the OTSG boiler tubes because of transport precipitated dense inorganic particles. However, presence other damage mechanisms, e.g. cor...
