6. The exhaust dyeing mill uses inefficient winch dyeing machines with liquor ratio > 1:7. (at least 80% of the production must not come from dyeing machines with liquor ratio > 1:7). 7. The mill does not reuse boiler's condensated water. 8. The mill does not reuse non-contact cooling water from all the machinery (excludes pure washing units).
constituents (minerals) and water (H2O). Most of the world's coal exists in the northern hemisphere. The United States, former Soviet Union and China together possess more than 80% of the ultimately recoverable resources (see Figure 7-1). It is important to remember that most of the world's land mass
Most of the ceramic dyeing materials possess the spinel structure. The main aspect of spinels is the presence of two metallic cations, A 2+ and B 3+, in tetrahedral and octahedral positions, respectively. The manner in which such sites are occupied depend on the calcining temperature [1], [2]. CoAl 2 O 4 is a double oxide with a normal spinel ...
The daily water consumption of an average sized textile mill having a production of about 8000 kg of fabric per day is about 1.6 million liters. 16% of this is consumed in dyeing and 8% in . Specific water consumption for dyeing varies from 30 - 50 liters per kg of cloth depending on the type of dye used.

The liquor ratio is reduced to between 1:2 and 1:5 and provides savings in terms of water and water treatment, chemical, and energy costs. This will bring up to 80-percent savings of liquor compared with costs associated with out-dated hydraulic machines, as well as significant savings of time.
Various physical properties such as the initial void ratio (e 0), effective stress, water content (), clay content (c (% < 2ηm)), and mean grain diameter (D 50) can affect the void ratio parameter.In the present study, these effective parameters are used as predictor variables. The ranges of input and output variables are presented in Table 2. ...

1 to 5 L of water are required to produce each litre of beverage; a proportion of this water forms part of the finished product and, therefore, this water must meet drinking water standards. Industrials continue to optimise the quantity of water used; some are close to a ratio of 1L of water per 1L of finished product.
Pulverized coal boilers fire finely powdered coal, typically with an average particle size of about 25 µm (0.001 in). Coal burns in suspension, like the combustion in an oil- or gas-fired boiler. Coal is pulverized in some type of large mill Pulverized coal is fired out into the furnace volume using burners that look somewhat like oil

Gas-fired Steam Boiler System in and Dyeing Industry Application Practice. June 25, 2021. Steam is one of the necessary energy sources for textile and dyeing production process. The steam comes from a steam boiler. The fuel for steam boilers usually includes coal, oil, gas and biomass. The most commonly used fuel is coal.
1. Introduction. Traditionally, the and dyeing sludge (PDS) generated during the treatment of wastewater in the and dyeing industry has been regarded as a troublesome and unavoidable by-product .Moreover, PDS is a complex waste that contains organic and inorganic substances, with a high percentage of water .However, more stringent …

coal - coal - Problems associated with the use of coal: Coal is abundant and inexpensive. Assuming that current rates of usage and production do not change, estimates of reserves indicate that enough coal remains to last more than 200 years. There are, however, a variety of problems associated with the use of coal. Mining operations are hazardous.

The synthetic dye industry arose directly from studies of coal tar.By 1850 coal tar was an industrial nuisance because only a fraction was utilized as wood preservative, road binder, and a source of the solvent naphtha.Fortunately, it attracted the attention of chemists as a source of new organic compounds, isolable by distillation.A leading researcher in this area, German chemist …
Even in Britain, water-power continued to overshadow steam-power in both number of mills and operating horsepower well into the nineteenth century. In other countries with more abundant water sources, less industrial know-how, and more expensive coal, water power continued to dominate steam even into the second half of that century.
