Compared with GB 29436.1-2012, GB 29436.2-2015, GB 29436.3-2015, GB 29436.4-2015, GB 31535-2015 and GB 32048-2015, apart from structural adjustments and editorial changes, the main technical changes are as follows:

a) the scope of application of the standard has been changed (see Chapter 1; Chapter 1 of GB 29436.1-2012, GB 29436.2-2015, GB 29436.3-2015, GB 29436.4-2015, GB 31535-2015 and GB 32048-2015);

b) some terms and definitions have been changed (see Chapter 3; Chapter 3 of GB 29436.1-2012, GB 29436.2-2015, GB 29436.3-2015, GB 29436.4-2015, GB 31535-2015 and GB 32048-2015);

c) grades of energy consumption limit per unit product have been added for the process route producing ethylene glycol from coal as raw material (see Chapter 4);

d) the grade values of energy consumption per unit product of methanol, ethylene glycol and dimethyl ether have been changed (see Chapter 4; Chapter 4 of GB 29436.1-2012, GB 29436.2-2015, GB 29436.3-2015, GB 29436.4-2015, GB 31535-2015 and GB 32048-2015);

e) the statistical scope of energy consumption for methanol and ethylene glycol production has been changed (see 6.1; 5.1 of GB 29436.1-2012, GB 29436.2-2015, GB 29436.3-2015, GB 29436.4-2015 and GB 32048-2015);

f) the method of accounting for raw material methanol and the conversion coefficient to standard coal in the calculation of dimethyl ether energy consumption have been changed (see 6.2; 5.2.5 of GB 31535-2015);

g) energy saving management and measures have been deleted (see Chapter 6 of GB 29436.1-2012, GB 29436.2-2015, GB 29436.3-2015, GB 29436.4-2015, GB 31535-2015 and GB 32048-2015);

h) the calculation requirements in Annex C for electricity consumption in methanol production, energy consumed through the use of energy-consuming working media and the various output energies have been changed (see Annex C; Annex A of GB 29436.1-2012 and Annex B of GB 29436.2-2015 and GB 29436.4-2015);

i) the principles and scope of calculation of methanol output in Annex D have been changed (see Annex D; Annex B of GB 29436.1-2012 and Annex A of GB 29436.2-2015, GB 29436.3-2015 and GB 29436.4-2015).
