Introduction of SY/T 0076-2008

Scope This Standard specifies the requirements for dehydration method, process calculation, equipment selection, corrosion protection, and other aspects of natural gas dehydration engineering during the construction of oil and gas field ground. This Standard applies to the design of newly-built, extended and rebuilt engineering of natural gas dehydration devices. The design and main parameters of dehydration with glycol absorption method, adsorption method and low temperature method may be selected according to this Standard. In addition to this Standard, the design of natural gas dehydration shall also meet the requirements of current national mandatory standards. 2 Normative References The following documents contain provisions which, through reference in this standard, constitute provisions of this Standard. For dated references, subsequent amendments to (excluding corrigendum), or revisions of, any of these publications shall not apply. However, all parties coming to agreements based on this Standard are encouraged to investigate the possibility of applying the latest editions of these documents.
