Datacor, a Florham Park, New Jersey software company for engineers, process manufacturers and chemical distributors, has acquired MySep, a Singapore developer of simulation software used to design and analyse process separators. Datacor announced the deal on October 13, 2026.
Terms were not disclosed. The deal was announced from Florham Park and reported over the following week by LNG Industry, Empowering Pumps, Chemical Engineering and Engineering.com.
MySep's software adds separator modelling to Datacor's engineering simulation products, and the company's base in Singapore gives Datacor a stronger presence in Asia Pacific and the Middle East, according to the announcement.
What MySep built
MySep's two products, MySep Studio and MySep Engine, use proprietary modelling and research-based correlations to predict how well a separator will perform: its separation efficiency, its pressure drop and how much liquid or gas is carried over into the outlet streams.
Engineers use the software to design new separators, evaluate equipment already installed and improve process reliability. Its users work across upstream oil and gas production, gas processing and LNG, refining and petrochemicals, Datacor said.
MySep Pte Ltd was incorporated in Singapore in 2013 as a spin-out of Kranji Solutions, according to its website, and also runs an office in Doha, Qatar, through MySep Middle East LLC. Its founder is Guy Hellinx. The company did not report outside funding.
“Engineers rely on MySep to design and analyze the performance of their separators.”
Why Datacor is buying
Datacor sells business and engineering software. Its engineering simulation line includes CHEMCAD for chemical process design and simulation, a flow simulation suite formerly sold as Applied Flow Technology, and GoldSim for probabilistic risk analysis. MySep fills a gap in that line-up for detailed separator design.
"MySep has built its software on more than a decade of dedicated research, and engineers across oil and gas have come to treat it as the reference for separator design and performance," said Tom Jackson, president of Datacor. He said the acquisition reflects the company's continued investment in specialised software.
A history of buying specialists
Datacor has grown in part by buying specialist software companies. In 2019 it bought TrackAbout, which gave it ERP, CRM and container-tracking software for the welding and industrial gas market, and in 2021 it acquired INFONETICS, a provider of software systems to welding supply and industrial gas distributors founded in 1984, with that company's management staying on.
Its product families now span business software such as ERP, CRM, formulation management and warehouse management, laboratory systems, and engineering tools. Before MySep, the engineering line included CHEMCAD and the Fathom, Arrow, Impulse and xStream flow modelling products, as well as GoldSim, according to Datacor's website.
Datacor's flow modelling unit was formerly known as Applied Flow Technology, or AFT; the announcement of the MySep deal on Empowering Pumps carried the byline "Datacor Pipe Flow Modeling, formerly AFT."
What happens to customers
Hellinx presented the deal as a way to offer MySep's users a wider set of tools.
"Engineers rely on MySep to design and analyze the performance of their separators," Hellinx said. "By joining Datacor, we can combine MySep's expertise with Datacor's broader software capabilities, enabling us to offer our customers more comprehensive solutions to their engineering challenges."
The announcement did not say whether MySep will keep its brand, whether its products will be bundled with CHEMCAD, or how many employees are joining Datacor. Engineering.com reported that the price was not disclosed and gave no headcount.
Where it fits
Chemical Engineering reported that the deal extends Datacor's engineering simulation portfolio and strengthens its presence in Asia Pacific and the Middle East, regions where MySep already has offices in Singapore and Doha.
For MySep's users, mostly engineers at oil and gas producers, gas processing and LNG plants, refineries and petrochemical producers, the immediate change is ownership. Jackson described the purchase as an investment in specialised software and "the depth of expertise behind it."
