Energy consumption is a very important consideration for reducing environmental impact and maximizing the profitability of operations. Since high temperatures are employed in hydrotreating (HDT) processes, hot effluents can be used to heat other cold process streams. The aim of the present paper is to describe and analyze the heat integration (during hydrotreating of crude oil in trickle bed reactor) of a hydrotreating plant’s process based upon experimental work.In this work, crude oil is hydrotreated upon a commercial cobalt-molybdenum on alumina catalyst presulfided at specified conditions. Detailed pilot plant experiments are conducted in a continuous flow isothermal trickle bed reactor (TBR) in which the main hydrotreating reactions, are hydrodesulfurization (HDS), hydrodenitrogenation (HDN), hydrodeasphaltenization (HDAs) and hydrodemetallization (HDM). The latter includes hydrodevanadization (HDV) and hydrodenickelation (HDNi). The reaction temperature, the hydrogen pressure, and the liquid hourly space velocity (LHSV) are varied within certain ranges, with constant hydrogen to oil ratio (H2/Oil).Experimental information obtained from a pilot plant, together with kinetics and reactor modeling tools,and a commercial process data are employed for heat integration process model. The optimization problem to minimize the overall annual cost is formulated as a Non-Linear Programming (NLP) problem, which is solved using Successive Quadratic Programming (SQP) within gPROMS.

The Cuu Long basin is equiped with infrastructures and processing facilities serving for large-scale crude oil drilling and production operations. However, most of resevoirs in this area are now depleted, it means that they have reached their peaks and started to undergo decreasing productivity, which lead to a noticable excess capicity of equipment. In order to benefit from those declined oil fieds and maximize performance of platforms, solutions to connect marginal fields have been suggested and employed. Of which, connecting Ca Ngu Vang wellhead platform to the CPP -3 at Bach Ho oil field; platforms RC-04 and RC-DM at Nam Rong - Doi Moi oil filed to RC-1 platform at Rong oil field; wellhead platforms at Hai Su Den and Hai Su Trang oil fields to H4-TGT platform at Te Giac Trang oil field are typical examples of success. Optimistic achivements gained recently urges us to carry out this work with the aim to improve oil production of small reserves and to make best use of existing petroleum technology and equipment at the basin. Results of the research contribute an important part in the commence of producing small-scale oil deposits economically.

AbstractPower-to-methane technology is a promising solution to facilitate the use of excess variable renewable energy for biomethane production. In this approach, hydrogen produced via electrolysis is used to upgrade raw biogas, which can be subsequently used as fuel or stored in the gas grid. Ex-situ biomethanation is an emerging technology that could potentially replace conventional energy-intensive biogas upgrading methods and allow CO2 utilization for biomethane production. This work provides a comprehensive overview on the current status of ex-situ biomethanation with particular attention to trickle bed reactor. The review includes description of ex-situ biomethanation and summarizes previous works on this topic. The key elements related to operational conditions, efficiency, and microbiology of ex-situ biomethanation using trickle bed reactor are described here. Additionally, the review highlights the technical and economic issues that have to be addressed for future development and large-scale implementation of ex-situ biomethanation.
