Allied’s focus is on providing clean technology products and services to industrial clients, in particular in the oil, gas, water and coal industry. In addition to engineering services, our main products are high quality re-refined lube oils. Our proprietary coal gasification process can be combined with the sequestration of CO₂, which can be used to enhance the recovery and production of crude oil. In China we manufacture catalysts for the removal of nitrogen oxides to serve the domestic and international markets. We provide engineering solutions for the removal of CO₂, NOx, sulphur and other particulates from industrial waste gases and to the water industry by designing and building water and (industrial) wastewater treatment plants.
