Guide for procurement of power station equipment - Part 4: Boiler auxiliaries - Section 6: Flue gas desulphurization (De-SOx) plant

Status: Valid

Scope
This standard gives guidance on writing the technical specification for the procurement of processes and equipment for the removal of sulphur oxides from the flue gas of steam generating plant for use in electricity generating stations (power stations). This Guide for procurement is not applicable to equipment for use in the nuclear reactor plant area of nuclear power stations. Other possible applications of such equipment have not been considered in the preparation of this Guide. This Guide covers: - wet, semi dry and dry systems; - systems to meet specific flue gas discharge requirements, for example sulphur content, dust content and temperature; - systems with and without marketable by-products; - systems to meet specified waste product discharge limits; - systems to meet limited choice of absorbent type and limitation of water consumption. The equipment covered by this Guide is defined by its function rather than design type. Therefore, the guidance to the specification is stated in performance terms rather than being specified by a detailed description of the equipment to be supplied. This Guide indicates to potential purchasers how their specification should be prepared so that: - the equipment type and capacity interfaces correctly with other elements of the systems particularly the boiler plant; - predicted performance is achieved; - ancillary equipment is properly sized; - reliability, availability and safety requirements are achieved; - proper consideration is given to the evaluation process and the quality measures to be applied. This Guide does not determine the type of specification (e.g. detailed, performance, functional) or the extent of supply for any given contract which is normally decided on the basis of the purchaser’s project strategy. It does not cover: - any commercial, contractual or legal issues which are normally in separate parts of an enquiry; - any allocation of responsibilities which are determined by the contract. This Guide does not p
