Norm of Water Intake - Part 35. Methyl Alcohol Produced by Coal1 ScopeThis Part of GB/T 18916 specifies the terms and definitions, calculation methods and norm of water intake of methyl alcohol produced by coal. This Part is applicable to the management of water intake of the existing, newly constructed, reorganized and expanded enterprises in the production of methyl alcohol produced by coal (including synthetic ammonia combined methanol whose capacity exceeds 10% of total ammonia).2 Normative ReferencesThe following documents are indispensable to the application of this Standard. In terms of references with a specified date, only versions with a specified date are applicable to this Standard. The latest version (including all the modifications) of references without a specified date is also applicable to this Standard. GB/T 12452 The General Principles of Water Balance Test in Enterprises GB/T 18820 General Principles of Stipulation of Water Intake Norm for Industrial Product GB/T 21534 Industrial Water Usage and Conservation - Terminology GB 24789 General Provisions on Equipping and Managing of the Measuring Instrument of Water in Organization of Water Using3 Terms and DefinitionsWhat is defined in GB/T 18820 and GB/T 21534, and the following terms and definitions are applicable to this document. 3.1 Methyl Alcohol Produced by Coal Methyl alcohol produced by coal refers to the production process of air separation oxygen production, coal-to-gas, gas purification, methanol synthesis and methanol refining, in which, coal, water and air are the main raw materials. 3.2 Methyl Alcohol Product Produced by Coal Methyl alcohol product produced by coal refers to products that are obtained through the production process of air separation oxygen production, coal-to-gas, gas purification, methanol synthesis and methanol refining, in which, coal, water and air are the main raw materials. 3.3 Quantity of Water Intake for Per Ton Methyl Alcohol Produced by Coal Quantity of water intake for per ton methyl alcohol produced by coal refers to the quantity of water that enterprises need to extract from various water resources for the production of per ton methyl alcohol product produced by coal.4 Calculation Methods4.1 General Stipulations 4.1.1 Scope of water intake Range of water intake refers to the quantity of water that enterprises extract from various conventional water resources, including water extracted from surface water (calculated by water supply from water purification plants), underground water, water supply engineering in cities and towns, and other water or water products (such as steam, hot water and geothermal water, etc.) that enterprises purchase from the market. 4.1.2 Range of water intake supply Range of water intake supply for methyl alcohol produced by coal includes primary production (the production process of air separation oxygen production, coal-to-gas, gas purification, methanol synthesis and methanol refining, in which, coal, water and air are the main raw materials), auxiliary production (including machine maintenance, boiler, air compression station, sewage treatment station, testing and inspection, comprehensive utilization transportation and self-owned power plant, etc.) and subsidiary production (including office, afforestation, plant canteen, bathroom and toilet, etc.). 4.1.3 Measuring of water intake The quantity of water intake shall be measured with enterprises’ Level-1 measuring table. 4.2 Quantity of water intake for Methyl Alcohol Produced by Coal The quantity of water intake for methyl alcohol produced by coal shall be calculated in accordance with Formula (1). Where. Vi---quantity of water intake for methyl alcohol produced by coal, expressed in (m3); Vg---water consumption of coal gasification, expressed in (m3); Vm---water consumption of methanol synthesis unit, expressed in (m3); Va---water apportionment of ancillary facilities of methyl alcohol produced by coal, expressed in (m3). 4.3 Quantity of Water Intake for Per Ton Methyl Alcohol Produced by Coal The quantity of water intake for per ton methyl alcohol produced by coal shall be calculated in accordance with Formula (2). Where. Vui---quantity of water intake for per ton methyl alcohol produced by coal, expressed in (m3/t); Vi---within a certain measuring time, total quantity of water intake during the production process, expressed in (m3); Q---within a certain measuring time, output of methyl alcohol product produced by coal, expressed in (t).5 Norm of Water Intake5.1 Water Intake Norm of Existing Enterprises The norm of water intake of existing enterprises in methyl alcohol produced by coal shall be ≤ 15 m3/t. 5.2 Water Intake Norm of Newly Constructed, Reorganized and Expanded Enterprises The norm of water intake of newly constructed, reorganized and expanded enterprises in methyl alcohol produced by coal shall be ≤ 11 m3/t. 5.3 Water Intake Norm of Advanced Enterprises The norm of water intake of advanced enterprises in methyl alcohol produced by coal shall be ≤ 9 m3/t.6 Instructions for Norm Usage6.1 In the management of the norm of water intake, enterprises’ water balance test shall comply with the requirement in GB/T 12452. 6.2 The configuration and management of water measuring instrument for enterprises in methyl alcohol produced by coal shall comply with the requirement in GB 24789. 6.3 Please refer to Appendix A for the method of calculating the quantity of water intake for methyl alcohol produced by coal.Appendix A(Informative) Calculation of Quantity of Water Intake for Methyl Alcohol Produced by Coal In the calculation of the quantity of water intake of methyl alcohol products, how to obtain the total quantity of water intake within a certain period of production becomes the key to accurate calculation of water intake quantity of methyl alcohol products. In accordance with the nature of methyl alcohol product production, the total quantity of water intake shall be calculated in accordance with this formula. Where. Vi---total quantity of water intake; Vg---water consumption of coal gasification. it refers to water or steam that is consumed in the stage of methyl alcohol production, which needs coal gasification to generate effective gas (CO + H2) and obtains methanol synthesis gas through transformation, refinement and hydrogen distribution. It includes steam, that is involved in chemical reaction. Mostly, it is steam brought out by effective gas, and cooling washing water that is generated through the rinsing of effective gas. Vm---water consumption of methyl alcohol device. it refers to water consumption in the conversion of circulating water hydration, softened water, demineralized water, steam and condensate water that are needed in methanol synthesis and the operation of methanol refining device; Va---water apportionment of ancillary facilities. it refers to water consumption that is apportioned to methyl alcohol device at a certain proportion by ancillary facilities (including office, afforestation, plant canteen, bathroom and toilet, etc.). ......Source: Above contents are excerpted from the full-copy PDF -- translated/reviewed by: www.ChineseStandard.net / Wayne Zheng et al.
