This screening process is firstly to separate between catalysts and non-catalysts. Then, the spent catalyst shall undergo second stage process, where the spent catalyst is separated based on its physical forms; pellets, dust, sweep and broken catalyst.
This involves: • Waste inventory management. • Decontamination process which involves the removal of impurities such as carbon and other volatile organic content from spent catalysts using pyrolysis i.e. controlled combustion technology which is also known as TOPS. Thus transforming it into non-scheduled waste.
There are 2 main types of industrial scheduled wastes namely solids and liquids. The solid scheduled wastes comprise mainly of spent catalyst from the petrochemical and oleo chemical industries. Whereas liquid scheduled waste generally refer to waste oil, Oil Base Mud (OBM), slop and sludge. QESB provides end to end management services for both types […]
The FRP processes all types of waste oil into stabilized diesel utilising QESB’s proprietary Robys Technology as well as other by-products such as fuel oil and naphtha. Representative of the latest innovation in waste oil recycling technology, it is a technically superior process in comparison to the traditional method where waste oil only undergoes filtration […]
QESB currently use the TOPS technology to treat spent catalyst as it is able to minimise physical impact during the process resulting in higher PGM yield. This process eliminates and reduces contaminants without altering the chemical composition of the spent catalyst.
This value added service is part of the screening process for separation of used catalyst with subtle physical differences. DG separates catalyst particles of similar size based on individual particle density. Seen from left to right: Mixed Heel Catalyst before DG Process, Usable catalyst after DG Process, Unusable spent catalyst after DG Process.
Initially, when the spent catalyst enters the CRP, it shall undergo the screening process. The first stage in screening process is to separate between catalysts and non-catalysts. Then, the spent catalyst shall undergo second stage process, where the spent catalyst is separated based on its physical forms; pellets, dust, sweep and broken catalyst.
The CRP is a special purpose facility that is capable of recycling spent catalysts and regenerating used catalysts generated by refineries, petrochemical, oleo chemical, pharmaceutical and chemical companies. The Thermal Oxidation Process System (TOPS) technology adopted at QESB offers substantial cost saving benefits to clients. Furthermore, it eliminates landfilling of the spent catalysts, providing a […]
Our facility, the Integrated Resource Recovery Complex (IRRC) comprises the Flexible Refinery Plant (FRP) and the Catalyst Recovery Plant (CRP). The FRP treats liquid scheduled waste i.e. waste oil and chemicals whilst CRP treats mainly solid scheduled waste, in particular spent catalyst.
Our facilities have been acknowledged by major refiners in the industry including: SABIN Metal Corporation of USA, HERAEUS Precious Metal GmBH of Germany, Johnson Matthey Corporation of United Kingdom and Solar Applied Material Technology of Taiwan. Major catalyst manufacturers including DOW Chemicals of USA, BASF of Germany and Haldor Topsoe of Denmark have also audited […]
