• Advice and expertise regarding catalyst regeneration,

At R.S.T. we strive to deliver a suitable and satisfactory solution for all catalyst handling activities by working closely together with refineries, catalyst suppliers, sub-contractors and catalyst regeneration companies during planning and execution of the total change-out operation.

After completion of each project we deliver a clear and comprehensive report of all executed works, including relevant visual imagery on video and/or digital pictures.
