dc.description.abstractThe low cost of steam combined with the maintenance free operation of steam ejectors has assured their unquestioned use in providing the necessary vacuum for crude distillation vacuum towers. However, the cost of steam production has risen to such an extent that new methods are required to achieve this vacuum. One such method of reducing steam use is a hybrid system composed of both steam ejectors and electric driven vacuum pumps. This paper describes the conversion of the vacuum system on the 140,000 BPSD crude still in the ARCO Petroleum Products Company's Houston Refinery to this steam ejector/ vacuum pump hybrid system. A comparison of the cost of operation of the original all steam ejector vacuum system versus the steam ejector/vacuum pump hybrid system is also included.en_US
