Description Somebody's got to manufacture the manufacturing plants, don't they? Established in 1974, Xytel designs and installs pilot facilities for petrochemical suppliers and other industrial manufacturers. The company's work spans the chemical and petrochemical processes: homogenous and heterogeneous, catalytic and non-catalytic. It also can manufacture petroleum refining plants. Xytel's plants cover more than 135 different products and can range in size from small, lab-scale projects to full-on turnkey mini-plants. More than half of Xytel's projects are from repeat customers. Xytel is owned by Enprotech Corporation, a subsidiary of ITOCHU International.
