Publication number: 20140142359Abstract: Mixed pentenes may be converted to propylene by feeding an alcohol, linear pentenes, and isopentenes to an etherification reactor. The alcohol and isopentenes may be reacted in the etherification reactor to convert isopentenes to tertiary amyl alkyl ether, which may be separated from the linear pentenes, recovered as a linear pentene fraction. The tertiary amyl alkyl ether may be fed to a decomposition reactor to convert at least a portion of the tertiary amyl alkyl ether to alcohol and isopentenes. The alcohol and isopentenes may then be separated to recover an isopentene fraction and an alcohol fraction. The isopentene fraction is then fed to a skeletal isomerization reactor to convert at least a portion of the isopentenes to linear pentenes, the effluent from which may be recycled to the etherification reactor. Ethylene and the linear pentene fraction may then be to a metathesis reactor to produce propylene.Type: ApplicationFiled: November 1, 2013Publication date: May 22, 2014Applicant: LUMMUS TECHNOLOGY INC.Inventors: Bala Ramachandran, Sukwon Choi

Method for managing and controlling stability in business activity monitoring and management systems
Patent number: 8126762Abstract: A stabilization methodology and system component in Business Activity Monitoring and Management systems. This enables firms to use Business Activity Management (BAM) systems to manage business activity by only responding to monitored data when the overall business performance can be improved. This enables firms to identify appropriate tradeoffs between potentially conflicting objectives while meeting business objectives. Information from BAM systems are analyzed based on models of the business process and different information filter criteria are assessed for their impact on business performance indicators. Based on this, a filter criterion is chosen which is executed by an information filter. The outputs from the information filter are used as the basis for deciding the inputs for business process execution.Type: GrantFiled: April 2, 2008Date of Patent: February 28, 2012Assignee: International Business Machines CorporationInventors: Bala Ramachandran, Li Chen -

Patent number: 7908161Abstract: A computer implemented method and a computer system implementing the method of a business process transformation wizard leads a business analyst through a series of steps to invoke business transformation patterns, in order to analyze the results of those processes. The wizard first prompts the business analyst to specify business objectives of process transformation. Required parameters are added to the business process model guided by the business process transformation wizard until the business process model is completed. Once the model is completed, the wizard prompts the business analyst to select transformation techniques or patterns for optimizing process parameters and, for each selected transformation pattern, optimizes process parameters using a selected optimization technique.Type: GrantFiled: March 21, 2008Date of Patent: March 15, 2011Assignee: International Business Machines CorporationInventors: Jay William Benayon, Kaori Fujiwara, Makoto Kano, Akio Koide, Bala Ramachandran
