EEMUA STANDARDS

EEMUA 213 - Emission reduction from oil storage tanks and loading operations The prevention and control of emissions of volatile organic compounds (VOCs) from storage tanks containing oil or chemical feedstocks or products is addressed by this new EEMUA Publication. Emission reduction has become of primary importance, not only for economic reasons but increasingly to minimize the impact on the environment. The Publication begins by introducing the main theory on how emissions can be minimised by focusing on the source of emissions. It then guides tank owners and operators, manufacturers, designers and specifiers to the most suitable tank type for particular feedstocks based on the true vapour pressure (TVP) of products. Background theories on possible solutions to prevent or reduce emissions are provided. Guidelines are also given on the treatment of the escaping vapours when the achieved level of emissions does not match the intended level or statutory requirements.

EEMUA 159 - Users' Guide to the Inspection, Maintenance and Repair of Above ground Vertical Cylindrical Steel Storage Tanks This users' guide is considered to be the most comprehensive available on storage tank inspection, maintenance and repair. It offers guidance on the inspection and maintenance of tanks built to BS or API standards for the storage of petroleum and chemical feedstocks and products and refrigerated gases. Key features for planning and executing inspection, maintenance and repair works on above ground vertical cylindrical steel storage tanks are set out. The publication covers description of the key tank components that require inspection and maintenance, degradation mechanisms and common inspection techniques, together with a description of the probabilistic (risk- and reliability-based) preventative mechanism concept. This latest third edition includes details on hydrotesting, repair and re-siting of tanks.

EEMUA 217 - Safe and effective operation of storage tanks  This publication provides guidance which aims to raise awareness of process safety, particularly in oil movements. It looks beyond the extensive existing standards and procedures, focusing on areas in which higher risk in oil movements exist. It covers oil movements in refineries, terminals and storage depots, and includes liquids stored under atmospheric pressure and LPG stored under pressure or under refrigerated and cryogenic conditions.


EN STANDARDS

EN 14015 - Environmental management - Environmental assessment of sites and organizations (EASO) (ISO 14015:2001)This International Standard provides guidance on how to conduct an EASO by applying a systematic process of identifying environmental aspects and environ mental concerns and, where appropriate, by determining their economic consequences and trade. This International Standard covers the functions and responsibilities of the parties interested in the evaluation (the sponsor, the expert and the representative of the assessee), and the stages of the assessment process (planning, consolidation and validation of information, interpretation and reporting). The process of conducting an EASO is illustrated in Figure 1. This International Standard gives no guidance on how to conduct other types of assessments about governmental, such as a) the initial analysis about nem ent b) environmental audits (including audits of management systems environmental audits and regulatory compliance), c) environmental impact assessments, or d) assessments about ronmental performance. The field measurements or environmental remediation of the site and the decision to launch these proceedings beyond the scope of this International Standard. This International Standard is not intended to be used as a specification standard for certification or registration, or the establishment of requirements for environmental management systems. The use of this International Standard does not imply that other norms or rules are imposed on the sponsor or the assessee.

EN 13121 - Environmental management - Environmental assessment of sites and organizations (EASO) (ISO 14015:2001)Part 1: This European Standard gives requirements for acceptance and usage conditions of raw materials for GRP tanks and vessels with or without lining for storage or processing of fluids, factory made or site built, non pressurised or pressurised, for use above ground. Part 2: This European Standard gives requirements for chemical resistance of composite materials used for GRP tanks and vessels for storage or processing of fluids, for use above ground. The tanks or vessels may be factory made or site built, with or without lining.


ASTM STANDARDS

ASTM C582 - Standard Specification for Contact-Molded Reinforced Thermosetting Plastic (RTP) Laminates for Corrosion-Resistant EquipmentThis specification covers composition, thickness, fabricating procedures, and physical property requirements for glass fiber reinforced thermoset polyester, vinyl ester, or other qualified thermosetting resin laminates comprising the materials of construction for RTP corrosion-resistant tanks, piping, and equipment. This specification is limited to fabrication by contact molding. Laminates shall be classified according to type, class, and grade: Types I and II; Classes P and V. Tensile strength and tangent modulus of elasticity, flexural strength, glass content, thickness, hardness, chemical resistance, and surface flame-spread classification tests shall be performed to conform to the specified requirements.


API STANDARDS

API 650 - Welded Tanks for Oil Storage: API Std 650 establishes minimum requirements for material, design, fabrication, erection, and testing for vertical, cylindrical, aboveground, closed- and open-top, welded carbon or stainless steel storage tanks in various sizes and capacities for internal pressures approximating atmospheric pressure (internal pressures not exceeding the weight of the roof plates), but a higher internal pressure is permitted when additional requirements are met. This Standard applies only to tanks whose entire bottom is uniformly supported and to tanks in non-refrigerated service that have a maximum design temperature of 93°C (200°F) or less.

API 653 - Tank Inspection, Repair, Alteration, and Reconstruction: Covers the inspection, repair, alteration, and reconstruction of steel aboveground storage tanks used in the petroleum and chemical industries. Provides the minimum requirements for maintaining the integrity of welded or riveted, nonrefrigerated, atmospheric pressure, aboveground storage tanks after they have been placed in service.

API 2000 - Venting Atmospheric and Low-pressure Storage Tanks: Covers the normal and emergency vapour venting requirements for aboveground liquid petroleum or petroleum products storage tanks and aboveground and underground refrigerated storage tanks, designed for operation at pressures from full vacuum through 103,4 kPa (ga) [15 psig]. Discussed in this International Standard are the causes of overpressure and vacuum; determination of venting requirements; means of venting; selection, and installation of venting devices; and testing and marking of relief devices.

Intended for tanks containing petroleum and petroleum products but it can also be applied to tanks containing other liquids; however, it is necessary to use sound engineering analysis and judgment whenever this International Standard is applied to other liquids.

This International Standard does not apply to external floating-roof tanks. This edition of API Std 2000 is the identical national adoption of ISO 28300:2008, Petroleum, petrochemical and natural gas industries-Venting of atmospheric and low-pressure storage tanks.
