1、CAN/CGSB-3.1000-2013Supersedes CAN/CGSB-3.1000-2007Vapour control systems in gasoline distribution networksICS 75.200National Standard of CanadaThe CANADIAN GENERAL STANDARDS BOARD (CGSB), under whose auspices this standard has been developed, is a government agency within Public Works and Governmen
2、t Services Canada. CGSB is engaged in the production of voluntary standards in a wide range of subject areas through the media of standards committees and the consensus process. The standards committees are composed of representatives of relevant interests including producers, consumers and other us
3、ers, retailers, governments, educational institutions, technical, professional and trade societies, and research and testing organizations. Any given standard is developed on the consensus of views expressed by such representatives. CGSB has been accredited by the Standards Council of Canada as a na
4、tional standards-development organization. The standards that it develops and offers as National Standards of Canada conform to the criteria and procedures established for this purpose by the Standards Council of Canada. In addition to standards it publishes as National Standards of Canada, CGSB pro
5、duces standards to meet particular needs, in response to requests from a variety of sources in both the public and private sectors. Both CGSB standards and CGSB national standards are developed in conformance with the policies described in the CGSB Policy and Procedures Manual for the Development an
6、d Maintenance of Standards. CGSB standards are subject to review and revision to ensure that they keep abreast of technological progress. CGSB will initiate the review of this standard within five years of the date of publication. Suggestions for their improvement, which are always welcome, should b
7、e brought to the notice of the standards committees concerned. Changes to standards are issued either as separate amendment sheets or in new editions of standards. An up-to-date listing of CGSB standards, including details on latest issues and amendments, and ordering instructions, is found in the C
8、GSB Catalogue at our Web site www.tpsgc-pwgsc.gc.ca/ ongc-cgsb along with more information about CGSB products and services. Although the intended primary application of this standard is stated in its Scope, it is important to note that it remains the responsibility of the users of the standard to j
9、udge its suitability for their particular purpose. The testing and evaluation of a product against this standard may require the use of materials and/or equipment that could be hazardous. This document does not purport to address all the safety aspects associated with its use. Anyone using this stan
10、dard has the responsibility to consult the appropriate authorities and to establish appropriate health and safety practices in conjunction with any applicable regulatory requirements prior to its use. CGSB neither assumes nor accepts any responsibility for any injury or damage that may occur during

13、a (SCC) is the coordinating body of the Canadian standardization network, which is composed of people and organizations involved in the development, promotion and implementation of standards. Through the collaborative efforts of Canadian standardization network members, standardization is helping to
14、 advance the social and economic well-being of Canada and to safeguard the health and safety of Canadians. The networks efforts are overseen by SCC. The principal objectives of SCC are to foster and promote voluntary standardization as a means of advancing the national economy, supporting sustainabl
15、e development, benefiting the health, safety and welfare of workers and the public, assisting and protecting the consumer, facilitating domestic and international trade, and furthering international cooperation in relation to standardization. An important facet of the Canadian standards development
16、system is the use of the following principles: consensus; equal access and effective participation by concerned interests; respect for diverse interests and identification of those who should be afforded access to provide the needed balance of interests; mechanism for dispute resolution; openness an
17、d transparency; open access by interested parties to the procedures guiding the standards development process; clarity with respect to the processes; and Canadian interest consideration as the initial basis for the development of standards. A National Standard of Canada (NSC) is a standard prepared
18、or reviewed by an SCC-accredited SDO and approved by the SCC according to NSC approval requirements. Approval does not refer to the technical content of the standard, as this remains the responsibility of the SDO. An NSC reflects a consensus of a number of capable individuals whose collective intere
19、sts provide, to the greatest practicable extent, a balance of representation of general interests, producers, regulators, users (including consumers) and others with relevant interests, as may be appropriate to the subject at hand. NSCs are intended to make a significant and timely contribution to t
20、he Canadian interest. Those who have a need to apply standards are encouraged to use NSCs. These standards are subject to periodic review. Users of NSCs are cautioned to obtain the latest edition from the SDO that publishes the standard. The responsibility for approving standards as NSCs rests with:

31、eveloped in support of the Canadian Council of Ministers of the Environment (CCME)s Environmental Code of Practice for Vapour Recovery in Gasoline Distribution Networks. The CCMEs Code of Practice addressed initiatives to reduce emissions of gasoline vapours, which are part of the volatile organic c
32、ompounds (VOCs), to the atmosphere. These compounds react with oxides of nitrogen on hot, sunny days to form ground-level ozone, a component of urban photochemical smog. This standard applies to vapour control system (VCS) equipment for gasoline transfers to cargo tanks, bulk plant storage and servi
33、ce station storage tanks (commonly called Stage I controls). In some existing gasoline distribution networks, the air and gasoline vapour in empty tanks is vented to the atmosphere as the tank is being filled. The VCS equipment recycles the air/vapour mixture from the tank receiving the gasoline bac
34、k to the tank delivering the gasoline, then back to a processing unit that recovers or destroys the vapours (Figure 1). The installation and use of standard vapour control systems will ensure that approximately 90% of the vapours on average are contained.This standard provides guidance to federal, p
35、rovincial and regional authorities having jurisdiction for vapour recovery in gasoline distribution networks and to owners who voluntarily implement vapour control systems. This standard specifies technical details for the design, installation, operation and maintenance of Stage I vapour control sys
36、tem. Implementation of Stage I vapour control systems in Canada is through regulation by the authority having jurisdiction. This standard is referenced in various regulations or permit requirements, and it is recommended that users consult both the regulations and this standard to satisfy all requir
37、ements. Conformance to this standard is recommended in the absence of regulation whenever Stage I VCS technology is installed to ensure compatibility in any systems across Canada.CAN/CGSB-3.1000-2013i CGSB 2013 All rights reservedContents1 Scope . 12 Normative references . 23 Terms and definitions 4

41、ocedures for the implementation of a vapour control system (VCS) in gasoline distribution networks including terminals, bulk plants, service stations and cargo tanks, commonly known as Stage I. ( See Figure 1 for a schematic representation). This standard does not include vapour control systems for
42、vehicle refuelling commonly known as Stage II, rail car, marine transfers or aviation gasoline facilities.This standard has been developed to provide regulators, users, installers and compliance authorities with a uniform installation reference for Stage I vapour control systems.Extent of coverage T
43、his standard provides performance criteria for equipment in use and specifies the type of interconnecting fittings to be used at terminals, bulk plants and service stations, and on cargo tanks. This standard does not provide design specifications for individual components such as mechanical design o
44、f a fitting or detailed piping layout.This standard also includes procedures for operating the Stage I VCS facilities in the various locations.Simplified schematics have been provided to illustrate possible field installations and checks.The test procedures included in this standard provide the basi
45、s for assessing the compliance of the equipment and systems with the requirements of the authority having jurisdiction.Application of this standard The user of this standard shall refer to the authority having jurisdiction in the application of this standard.Certain considerations are required in th
46、e application of this standard.The maximum back-pressure at the cargo tank to provide sufficient head to drive the vapour recovery unit (VRU) is specified as a maximum 4.5 kPa (18 in. of water).There is a concern with the flow characteristics of poppetted vapour connections. Poppetted adaptors with
47、low restriction to flow may be necessary for some applications and are recommended for vapour connections to cargo tanks.For equipment and safety protection, the use of pressure/vacuum (PV) vents on underground tanks is not recommended as such devices do not improve vapour recovery.Flame arrestors c
48、onforming to U.S. Underwriters Laboratories Inc. (UL1) standards and documents are recommended in vapour recovery lines for the fire protection of VRU systems. Flame arrestors shall be sized so as not to increase system back-pressures beyond the levels specified in maximum back-pressure stated above
