In a relevant development in November, Iran's Research Institute of Petroleum Industry (RIPI) and Germany's Raschig signed a memorandum of understanding (MoU) on new oil-related technologies transfer.
The MoU was signed by RIPI deputy for technologies and international relations Mansour Bazmi and Raschig technical director Michael Schultes in Tehran.
Rasching is one of the most credible companies in the world and many industries are cooperating with it, Bazmi said after signing the MoU.
"The cooperation will be on transfer of technology on equipment used in distillation columns in refineries and petrochemical plants, designing the distillation columns based on the products of the Germany company, training specialists and experts of RIPI in related spheres," he added.
RIPI that has conducted a series of activities on designing distillation columns, will be able to use new approaches of Raschig in its projects, according to the official.
The German official, for his part, expressed the company's eagerness to get more information on RIPI to boost the cooperation in the future.
"Conducting some research, we found Iran a country suitable for boosting cooperation and commercializing our products," he said.
