“…29 While it is possible to get more accurate results if kinetic information was available, we used this simplifying assumption to complete our simulation. This reactor operates at 4532 °F temperature, 1 and the gaseous product mixture containing 1,3-butadiene, ethylene, and hydrogen is cooled to 207 °F via a cooler (HX-20). This gaseous mixture is sent to compressor K-5 where it is compressed to 363 psia and 656 °F.…”

“…Higher yields of butadiene are observed at a temperature of 4532 °F, where 30% molar conversion is achieved compared to operating conditions of 1832 °F, where only 16% molar conversion is accomplished. 1 Our literature survey indicates that the manufacture of 1,3butadiene from natural gas in an integrated plant has not been reported yet. An integrated plant provides two main advantages: (1) storage and transport of intermediate products are not required and (2) capital and operating costs can be reduced due to heat integration.…”

“…The production capacity worldwide for 1,3-butadiene is 13 million ton per annum (MTPA). 1 The conventional production route is to crack naphtha to produce ethylene as the main product and 1,3-butadiene as a side product of the process. 2,3 Naphtha is fed to a pyrolysis furnace where cracking takes place at relatively high temperatures of around 1520 °F.…”

“…While it is possible to directly convert methane to 1,3-butadiene via the production of acetylene in a pyrolysis reaction in a supersonic reactor, this is generally not considered at an industrial scale due to difficulties associated in operating at supersonic conditions. 1 A variety of companies have commercialized the process for ethylene manufacture from natural gas in the past three decades. For instance, ExxonMobil, UOP/Hydro, and Sinopec have developed the methanol-to-olefins (MTO) and methanol-to-propylene (MTP) processes.…”

1,3-Butadiene is an important feedstock in the production of rubbers and plastics, such as styrene butadiene rubber, polybutadiene rubber, and styrene butadiene latex. As the cracker feedstock around the globe is trending toward lighter feedstock from shale and natural gas, the sustained production of 1,3-butadiene in olefin plants, which is traditionally made via naphtha cracking, is facing big challenges. In this research, it is shown that 1,3-butadiene can be produced from natural gas via a novel integrated plant. The manufacturing process consists of the following steps: (1) conversion of natural gas to methanol, (2) conversion of methanol to ethylene, and (3) conversion of ethylene to 1,3-butadiene. The ASPEN Plus environment is utilized to simulate the overall plant, and the predictive capabilities of this model are tested by comparing the results from experimental data from individual plants. Then, energy-saving and capital cost reduction opportunities are explored by utilizing heat integration tools.

Traditionally, comprehensive process design has relied on a sound and insightful techno-economic analysis framework. In particular, once a base-case design is selected, further analysis is carried out to assess the environmental impact as well as possible process safety implications. Furthermore, limited modifications to the base-case design are typically carried out to concurrently address environmental and safety concerns. This sequential approach can thus lead to suboptimal process system designs when multiple objectives of profitability, sustainability, and safety are considered. Indeed, the simultaneous consideration of these objectives during the conceptual design phase of a project should lead to superior performance profiles. In the present work, a new approach for the incorporation of safety and sustainability considerations early enough during the conceptual design of the process is presented. This approach is based on extending the conventional return on investment (ROI) analysis to include positive or negative impacts of potential design changes that emerge when sustainability and safety issues are simultaneously considered. Within the proposed context, this becomes possible through a meaningful and potentially insightful extension of the traditional economic performance metric to account for safety and sustainability-relevant performance criteria. In particular, a safety and sustainability weighted return on investment metric (SASWROIM) is introduced to systematically integrate the aforementioned multiple objectives and therefore inform the conceptual design stage in a methodologically sound and insightful manner. To illustrate the usefulness of the proposed approach, two case studies on the production of butadiene and methanol are considered and analyzed within the above context. It is demonstrated that this new approach can be used by decision makers to reliably evaluate the economic viability of a project as well as the assorted impact on the environment and process safety.

The concept of eco-industrial parks (EIPs) for integrating resources and infrastructure among several adjacent plants offers synergistic opportunities that can lead to enhanced profit, reduced pollution, and increased conservation of natural resources. A special class of EIPs, carbon-hydrogen-oxygen symbiosis networks (CHOSYNs), has been recently introduced for integrating hydrocarbon processing plants. The synthesis of CHOSYNs establishes multiscale benchmarks for the design by tracking the atomic fluxes of carbon, hydrogen, and oxygen atoms to develop rigorous performance benchmarks. Multiscale process synthesis techniques are then used to generate system configurations that achieve the benchmarks and to establish tradeoffs among various objectives. To date, all published research contributions for optimizing the design of CHOSYNs have focused on integrating mass among the participating plants. Opportunities exist to further increase resource efficiency by also incorporating energy integration into the design of CHOSYNs. This work addresses the design of CHOSYN through the inclusion of mass and energy integration in the benchmarking and synthesis of the network configurations. In addition to the benefits from mass and heat integration, further reduction of resource usage is explored through the incorporation of an integrated trigeneration facility. The design of CHOSYNs is evaluated by assessing economic and environmental objectives. A case study is established and solved demonstrating the mass and energy targeting techniques of this approach. Significant economic savings and sustainability enhancements of each participating plant in the CHOSYN are obtained. The outcome of the case study displays the synergistic relationship between each participating plant.
