Smart Operating
GC has adopted innovative technologies to design, develop and improve its production processes in order to align it with the principles of circular economy. By maximizing resource efficiency, utilizing renewable energy to mitigate the impacts of climate change, and stabilizing the production processes in the past year, GC has develop of business operation in accordance to ‘smart operating’. This includes
Energy Conservation Projects
GC has performed Heat Integrate Deheptanizer Overhead with Benzene Column Reboiler Project in operating site of GC Branch 5 (Aromatics Plant 2), in order to reduce steam consumption from heat recovery process between the upper part of C7 distillation column and the reboiler of benzene distillation column according to heat integration principle.
Reduced energy consumption by
GJ per year
Reduced greenhouse gas emissions by
tons CO2 equivalent per year
Operating cost saving
million THB per year
GC has implemented the project to enhance the energy efficiency in the Company’s refinery plants by reusing heat lost in atmosphere into production process, resulting in reduction of natural gas consumption at furnaces, electricity generation and steam production processes.

Waste Reduction Programs
Read moreReusing Waste as Alternative Raw Material
Using Mercury waste from the Aromatics and Refinery plants as raw material for medical equipment production.
Promoting and encouraging employees to segregate waste in office, e.g. segregating plastic, glass, and paper waste for recycling and segregating food waste to be used as animal feed by the surrounding community, etc.
Installing Seawater Reverse Osmosis (SWRO) and Wastewater Reverse Osmosis (WWRO) systems to monitor and improve wastewater quality discharged from wastewater treatment system to ensure that the discharged amount can be used and reentered in the operating process.
Reusing off gas from Aromatics Plants, i.e. ethane, propane, butane, as substrate for olefins plants instead of flaring, and using heavy residue from Phenol Plants as raw materials for fuel oil production in Refinery plant. In 2020, the system can
generate an income for the company of over
million THB per year.
