Alleima provides Preem within the inexperienced transition of the aviation business
Alleima will provide Preem with warmth exchanger tubes for use within the conversion of the Lysekil refinery from fossil to renewable fuels. The funding is a vital a part of Sweden’s inexperienced vitality transition and can make Preem the most important producer of renewable jet gasoline in northern Europe.
The redevelopment of Preem’s IsoCracker plant (ICR) in Lysekil began late 2024. As soon as accomplished, it should produce 1.2 million cubic meters of renewable fuels yearly and cut back fossil carbon dioxide emissions at consumer degree by 2-3 million tons yearly. On the similar time, Preem will cut back fossil gasoline manufacturing by a corresponding quantity.
Tommy Johansson, undertaking supervisor for the ICR undertaking at Preem, says :
Decreasing greenhouse gasoline emissions is among the nice challenges of our time.
“I’m subsequently proud that Preem is now making the largest change within the firm’s historical past. We’re doing this by changing the diesel plant on the refinery in Lysekil. When the conversion is full, we might be Scandinavia’s largest producer of renewable jet gasoline,”
The changeover implies that Preem will not use fossil uncooked supplies reminiscent of crude oil, however renewable uncooked supplies as a substitute. To make this potential, superior expertise is required, not least within the pre-treatment unit (PTU) that’s to be constructed. The uncooked supplies might be pre-treated and purified at excessive temperatures earlier than getting used within the manufacturing of renewable fuels reminiscent of Hydrotreated Vegetable Oil (HVO), the diesel constructed from vegetable oils or plant merchandise and Sustainable Aviation Gas (SAF).
The processes in refineries typically place excessive calls for on the supplies used and renewable fuels are notably difficult. The uncooked supplies used normally include chlorides, which may trigger corrosion. Subsequently, particular supplies are required that may stand up to excessive temperatures and aggressive chemical environments with out corroding.
Group Coek a warmth exchanger producer and one in all Alleima’s long-standing clients, booked the order with Preem
Patrick van Roy, CSO of Group Coek, says :
Sanicro® 35 is used for the warmth exchanger tubes, channels, and baffles of the warmth exchangers. The fabric was chosen primarily due to its good corrosion resistance.
“We at Group Coek are very happy with this collaboration with Alleima, an organization with which now we have an extended and constructive working relationship,”
Barinder Ghai, Director Technical Advertising, New Enterprise Improvement for the Tube division at Alleima, says :
We’re very glad that Alleima has been trusted to produce warmth exchanger tubes and pipes to Preem.
“Alleima has an extended historical past as a provider of particular metal to Preem’s refineries. The particular alloy Sanicro® 35, is an austenitic stainless-steel alloy meant for very corrosive environments and an alternative choice to the usage of nickel bases within the warmth exchangers for preheating and cooling the renewable uncooked supplies within the PTU. Earlier than a call may very well be made, we carried out intensive lab exams along with Preem, which confirmed that Sanicro® 35 can stand up to the intense circumstances and course of environments of the pretreatment plant. This resulted in a robust different to the dearer nickel- primarily based alloys which can be in any other case used,”
