The innovative Way to achieve 'Zero Emissions' in Sulphur Recovery Facilities

摘要

KT-Kinetics Technology S.p.A. (KT) is developing a New Concept of Sulphur Recovery Unit (SRU), utilizing a Novel Process, an innovative catalyst and a new process scheme for the treatment of all Sour Gases feedstock. The New Sulphur Recovery Configuration, with customised and tailor-made selection of operating parameters, is full in compliance with the strictest environmental emission regulation and allows achieving the goal of "zero emissions" to the atmosphere. The core-part of the Innovative SRU is the Sour Gas Selective & Oxidative Auto-thermal Process (Sour Gas SOAP), fully integrated with KT RAR Tail Gas Treatment (TGT) plant configuration. The distinguishing feature of the Novel Process is the production ofH2 and Liquid Sulphur through Sour Gas Cracking Catalytic Partial Oxidation, instead of S02 and Liquid Sulphur as per benchmark process technology. For the New SRU a very flexible plant scheme has been developed with the aim to be utilized as it is in all possible Industrial Application: Petroleum Refinery, Oil & Gas Field, Coal Gasification, Integrated Gasification Combined Cycle (IGCC) Complex and Chemical & Petrochemical Complex. The purpose of this paper is to describe the Novel Process, mechanism of reaction and the relevant Plant Configuration as well as the CAPEXand OPEX Analysis for a SRU installed in a Petroleum Refinery and in a Gas Field. The main results of CAPEX and OPEX Analysis is a reduction up to 30% with the final goal of "zero emissions".
