“…The first approach linearizes the quadratic terms of augmented Lagrangean and fixes the minimum number of variables to values of previous iteration . The second approach directly fixes the minimum number of variables in the augmented Lagrangean relaxation problem to values of previous iteration . We follow the second approach to separate the ALRP into two subproblems—SP1 and SP2.…”

A methodology is proposed to reduce the cost and capital intensity of small-scale chemical processes by creating new opportunities for economies of numbers through standardizing the equipment designs across multiple processes. We depart from asynchronous design of single-processes and adopt a common-functionality based simultaneous design of multiple processes that use similar unit operations. A generalized cost function is used to appropriately balance the trade-offs between economies of scale and economies of numbers. An optimization-based framework for design standardization is developed and illustrated using two case studies. The first involves the simultaneous synthesis of methanol and ammonia processes, and the second addresses the optimal synthesis of multi-column natural gas liquid (NGL) fractionation processes for different natural gas sources. We observe that considerable reduction in capital intensity of small-scale processes is possible through equipment standardization.

During the lifecycle of an oilfield project, well development is a critical phase due to intensive investments required for capital cost. Determining whether it is economical to develop an oilfield or not and finding the best plan for field development are the main concerns in this field of study. Drainage area development and production planning are crucial in a steam assisted gravity drainage (SAGD) project of the oil sand industry. In this study, an optimization framework for planning the development of SAGD drainage areas under uncertainty is presented. The proposed framework includes the following two major elements. First, a mixed integer optimization model is developed to arrange the multiperiod development plan of the drainage areas with consideration of capital and steam allocation restrictions. Second, uncertainties in crude oil price and reservoir production are investigated based on a multistage stochastic programming model. The results demonstrate that the method can effectively generate an economically optimal development plan that maximizes the profit.
