ENERGY-EFFICIENT CO2 REMOVAL PROCESS
GV LOW ENERGY PROCESS

L. Tomasi , Chief Engineer
Giammarco-Vetrocoke, Venice - Italy.

Among activated HPC processes wich are preferred for cost and reliability, the GV low-energy process in its updated version is the most interesting since it combines low energy consumption with excellent performance and low investment cost. This paper explores its main characteristics.

CO2 removal proceses based on activated hot potassium carbonate solutions (HPC) are by far the preferred in ammonia complexes. Their asset lies in the absence of corrosion problems allowing the use of CS for the most part of the equipment; in the economical chemicals readily available anywhere - two of the resons why these plants are absolutely the cheapest - and in the plant reliability as well as highly appreciated.

In this field, GIAMMARCO-VETROCOKE (GV) holds a prominent position for having discovered and introduced into the industrial use activators; for its extensive experience acquired over more than 40 years in designing acid gas removal system; for the number of plants licensed where its non-toxic glycine activated (glycine-secondary amine) solution have successfully replaced the arsenical solution. GV has always been in the forefront in developing low-heat-consumption schemes at limited investement cost and its updated technology offers absolutely the lowest energy consumption among activated HPC plants, in the line with the best among the physical processes.
