Davy Process Technology has the capability to design global scale plant for the conversion of most generally available feedstocks and has the ability to optimally integrate a number of in-house and external technologies to provide the best solution for any particular application.
Depending on feedstock composition, its price and availability, the most appropriate intermediate gas and the desired ultimate product, one or more combinations of the above pre-treatment, gas conditioning and purification unit operations can be provided to optimise plant performance. Many of the catalysts used in downstream processes are poisoned by trace components in the hydrocarbon feed, particularly sulphur, chlorine and metal compounds. Sulphur is the commonest problem, the nature and level of sulphur species being dependent on the source, pre-treatment and molecular weight of the hydrocarbon. Chlorine compounds are less common and metal compounds are typically found in some heavier LPG and naphtha feeds.
Davy Process Technology approaches new carbon conversion projects with wide experience and an open mind about flowsheet design and we work with each client to arrive at the optimum solution. This means that the best combination of pre-treatment, conditioning and purification will be integrated with the main process so that optimum conditions allow for energy conservation by heat exchange and the recycling of waste or dilute streams to minimise emissions including low NOx operation. We offer a comprehensive design and licensing service including facilities for catalyst reprocessing or reactivation and integrally safe catalyst handling and management systems. These systems work efficiently to ensure maximum reliability for mainstream operations.
