KUALA LUMPUR: SumiSaujana Group Bhd's wholly-owned subsidiary SumiSaujana TCM Chemicals Sdn Bhd (SSTCM) has entered into a memorandum of understanding (MoU) with PT Kilang Pertamina Internasional (KPI), SPCI HELM Malaysia Sdn Bhd (SPCI HELM) and Denmark-based TOPSOE A/S (TOPSOE) to jointly explore the development of a wet gas sulphuric acid (WSA) facility at one of KPI’s refinery units in Indonesia.
Under the MoU, the parties will collaborate to evaluate the technical, commercial and financial feasibility of implementing a WSA project under a Build-Own-Operate-Transfer (BOOT) model.
In a statement, the group said the proposed facility will convert acid gas produced during refinery operations into commercial-grade sulphuric acid, while recovering heat to be reused, helping reduce emissions and comply with environmental regulations.
"This circular waste-to-value approach helps reduce sulphur emissions and other pollutants, lowers overall greenhouse gas emissions, supports compliance with environmental regulations, and aligns with refinery operators’ broader low-carbon and energy efficiency objectives by turning industrial waste into useful products and energy," it said.
SSTCM is responsible for leading the technical and commercial evaluation of the project, leveraging its experience in speciality chemicals and refinery-related solutions.
TOPSOE, a globally recognised technology provider with a strong focus on energy efficiency, decarbonisation, green energy and for its proprietary WSA technology, will contribute process design inputs, indicative licensing parameters and technical advisory support, while SPCI HELM will provide insights into sulphuric acid market demand, distribution and regional supply dynamics.
"While the collaboration is currently at the evaluation stage, it allows us to apply our technical expertise, strengthen our regional presence, and build a foundation for potential long-term participation in large-scale refinery infrastructure projects, subject to successful feasibility outcomes and the execution of definitive agreements,” said SumiSaujana executive deputy chairman Toh Chee Seng.
