MOSCOW (MRC) -- Raizen Argentina’s refinery in Buenos Aires, working with Shell Catalysts & Technologies (SC&T) and more than 25 Argentine companies, has built and erected a new crude distiller column in November 2021, according to Hydrocarbonprocessing.
It is part of a project that strategically positions the refinery for the future in relation to the processing of unconventional crude, such as that from the Vaca Muerta basin. It also improves the flexibility of the refinery and allows it to adapt more easily to current market conditions.
The new crude distiller column measures almost 50 meters high and six meters in diameter, weighing more than 245 tons. It took seven days to transfer the column from the fabrication site to the refinery, travelling more than 60 kilometers in a special, 77 meters long truck.
The new crude distiller column and the revamped side stripper and drier columns should allow uninterrupted operation throughout its target cycle length. SC&T developed the new crude distiller column design specifications and performed adequacy checks for the side stripper and drier columns. SC&T also provided the internals design consisting of Shell Calming Section Trays, Structured packing and Conventional Downcomer trays.
At project completion, the new crude distiller column will be integrated with other existing equipment in the Crude Distiller 5 unit. Although this is unconventional, the team was able to overcome some design challenges and use a significant portion of the existing assets. This enables Raizen Argentina to maintain their operational efficiency and productivity along with a wider operating range.
This project enables the refinery’s Crude Distiller 5 unit to process shale oil from the Vaca Muerta basin. This allows Raizen Argentina to optimize its crude diet from a strategy and economic standpoint. The unit aims to process maximum throughput of light API shale oil while maintaining the capability of processing also mid API range crude oil.
As MRC informed previously, Royal Dutch Shell plc. said in November that its petrochemical complex of several billion dollars in Western Pennsylvania was about 70% complete and in the process to enter service in the early 2020s. The plant's costs are estimated to be USD6-USD10 billion, where ethane will be transformed into plastic feedstock. The facility is equipped to produce 1.5 million metric tons per year (mmty) of ethylene and 1.6 mmty of polyethylene (PE), two important constituents of plastics.
Ethylene and propylene are feedstocks for producing PE and polypropylene (PP).
According to MRC's ScanPlast report, Russia's estimated PE consumption totalled 2,047,100 tonnes in the first ten months of 2021, up by 17% year on year. Shipments of all grades of ethylene polymers increased. At the same time, PP shipments to the Russian market were 1,226,530 tonnes in January-October 2021, up by 26% year on year. Supply of propylene homopolymers (homopolymer PP) and block-copolymers of propylene (PP block copolymers) increased, whereas supply of injection moulding stat-copolymers of propylene (PP random copolymers) decreased significantly.
Royal Dutch Shell plc is an Anglo-Dutch multinational oil and gas company headquartered in The Hague, Netherlands and with its registered office in London, United Kingdom. It is the biggest company in the world in terms of revenue and one of the six oil and gas "supermajors". Shell is vertically integrated and is active in every area of the oil and gas industry, including exploration and production, refining, distribution and marketing, petrochemicals, power generation and trading.
