Sentence examples for coal production process from inspiring English sources

Out-of-seam mining has a pervasive impact (Fig. 2) on each step of the coal production process (Chugh et al. 2013).

As the capital investment in underground coal mining is huge enough by the standards of any conventional industry hence coal production process has to be very efficient to make commercially viable.

This paper suggests an alternative method for coal flotation which has a significant effect on quality, coal production processes and plant design.

The system can realized poly-generation of gases, tar and power from coal in an integrated production process.

Currently, there is no direct method to obtain coal reservoir permeability during the gas production process because almost no productivity test is applied in this process.

During the CBM production process, the coal reservoir permeability changes all the time.

Production process of coal preparation plant is a complicated process of multi-layer, which is determined by the production characteristics.

Single coal based chemicals production processes emit large amount of CO2 during conversion of the syngas to the high H2/CO ratio feed gas for chemicals synthesis.

In other words, less H2 is needed from the gas of coal gasification, which simplifies the SNG production process and reduces the cost.

Among the coal-to-SNG production processes, SNG is produced through the four major steps, i.e., coal gasification, water-gas-shift (WGS) reaction (CO + H2O ↔ H2 + CO2), gas cleaning and CO methanation (3H2 + CO ↔ CH4 + H2O) (Shinde and Madras 2014; Wang et al. 2015).

This study delivers fundamental understandings of coal fines generation and migration during the CSG production process, and useful guidelines are suggested to be implemented in the field to minimize production loss induced by coal fines behaviours.
