Sobre a classificação do gás natural

2016-07-26View Original

Thread Content

A norma nacional para gás natural, “GB 17820-2012”, classifica o gás natural em três categorias: primeira, segunda e terceira. Quais são as aplicações do gás natural da terceira categoria? A gás de uso doméstico pertence a quais categorias de gás natural? Ou forneçam algumas publicações acadêmicas, obrigado a todos!

A classificação do gás natural pode ser feita com base no valor calórico do gás natural e na sua concentração de hidrogênio； Ainda não existem normas para gás natural.
