AB-In-Bev

(EPCM services) Hatch Africa

A B-InBev appointed Hatch to provide the EPCM services for a new Co-Generation plant at the Rosslyn Brewery based in Pretoria, Gauteng. The scope of the Co-Generation plant included the gas fired turbine and generator, a heat recovery steam generator, hot water recovery circuit, a new high-pressure gas line and upgrading of the electrical reticulation system and the control network. The Co-Generation plant was designed to deliver 4 MW of electricity, 28,5 tonne/hour steam and 41 tonne/hour of hot water, using the same amount of gas previously burned in gas fire boilers to generate the same amount of steam. The project involved complex brownfield construction activities to ensure no interruption of existing brewery production and processes while connecting to the existing electrical and control networks. The outcome of the project was a successful delivery of the project: • Safety – Zero LTI in 164 000 hours.

• Performance – Exceeding the guaranteed efficiency of 88%. • Financial indicators – Payback in less than four years. AB-InBev’s Rosslyn Brewery is the largest brewery in South Africa and key to the company’s Southern African production targets. Brewing is an energy intensive process requiring large quantities of electricity and steam, and a reliable source of affordable energy is essential. In February 2016, with ongoing load shedding affecting operations, AB-InBev appointed Hatch to conduct an engineering study of options to provide a source of in-house electrical generation while, at the same time, optimising the brewery’s steam production process to ensure security of supply. The study identified attractive benefits for the brewery if they installed a natural gas fired Combined Heat and Power (CHP) plant. Based on the outcome of the study, AB-InBev extended Hatch’s appointment to provide full EPCM services to design, construction manage and commission the entire CHP plant. z
