Carburization inspection robots for radiant tubes inside ethylene cracking furnaces

Tiyawongsakul, T., Rayong Engineering & Plant Service Co. Ltd.

In an olefins plant, the reliability of ethylene cracking furnaces is one of the deciding factors used to indicate whether or not the plant can be operated at its design productivity.

Modified revamp process to reduce energy use in an SDA unit

Kumar, S., Nanoti, S. M., Garg, M. O., CSIR-Indian Institute of Petroleum; Amutha, R., Nandagopalu, N. V. N., Chennai Petroleum Corp. Ltd.

Solvent deasphalting (SDA) is emerging as a low-cost, bottom-of-the-barrel upgrading process to recover valuable oil from short residue. This oil can either be further processed to make lube-oil-based stocks or cracked in secondary processing units.

Improve energy efficiency with enhanced bundles in tubular heat exchangers

Müller, A., Kropp, A., Köster, R., BAYERNOIL Raffineriegesellschaft mbH; Fazzini, M., Koch Heat Transfer Co. LP

From 2008 to date, 45 twisted tube heat exchangers and bundles have been installed at BAYERNOIL refineries in different units and services, allowing higher heat recovery and contributing to BAYERNOIL’s energy targets.

Recommended practices for fired process heater instrumentation and control

Schaffer, C., Burns & McDonnell

Fired process heaters are one of the most critical pieces of equipment within many refinery and petrochemical facilities. Proper instrumentation and control of the equipment has direct bearing on the successful operation of the process, as well as on overall facility process safety.

A deeper examination of thermal expansion issues in process equipment and piping

Tharakan, J., Suncor Energy Products

Piping and process equipment that operate at high temperatures experience thermal expansion. If free thermal expansion is restrained, mechanical stresses are created within the component.

IR camera technology provides new perspective on furnace inspection routines

Boccella, M., FLIR Systems, Inc.

A few years ago, managers at a US-based oil refinery called in an expert to inspect their oil furnaces with an infrared (IR) camera.

Reduce coke formation and save operating costs with optimization of DMDS into ethane cracking furnaces

Hay, G., Rasouli, G., Carbognani-Arambarri, L., Virtual Materials Group Inc.; Suzuki, R., Urata, K., Inoue, M., JX Nippon

Steam cracking furnaces produce olefins, which are high-value feeds in the petrochemical industry. Coke formation is an unavoidable part of a thermal cracking furnace.

Key design considerations for vacuum process condensers

Lines, J., Graham Corp.

The crude oil refining and petrochemical industries make extensive use of condensers that operate under vacuum (i.e., below atmospheric pressure). Distillation is the most common process using these condensers, either as a process precondenser ahead of an ejector system, or as an intercondenser within an ejector system.

Managing complex changeover processes for integrated cracking furnace safety

van Diessen, S., Sadowski, S., Netherlocks Safety Systems

Cracking furnace operations (e.g., for the steam cracking of naphtha feedstock into olefins) are an essential part of hydrocarbon (HC) refining; however, they are known to be potentially dangerous and complex to manage.

Technip awarded contract to supply furnaces for ethylene plant in Russia

Technip was awarded a contract to provide engineering and procurement of three proprietary SMK grassroots furnaces at Kazan, Republic of Tatarstan, Russia.
