About this presentation

Tube side condensers are commonly used in the chemical process industry. When condensing single component vapours heat transfer coefficients are high. The situation changes when condensing multicomponent mixtures or condensation with inert components present. Under these conditions, the performance of condensers is often controlled by additional mass transport limitations between the liquid and vapour interface. To maintain the condensation process, the multicomponent vapour must be cooled. This becomes a challenge since particularly at low vapour velocities the resulting sensible vapour cooling coefficients are low. In the case of horizontal in-tube condensation, at low vapour velocities towards the end of the condensation process stratified gravity-controlled flow occurs. This leads to thermodynamic non-equilibrium which makes it difficult to correlate with heat exchanger design software. The installation of hiTRANTM Thermal System improves different aspects of the tube side condensation process. The main benefit is the increased sensible vapour cooling coefficient. The wires produce increased turbulence in the condensate film, and film and vapour mixing contribute to a reduction in mass transport resistance in the vapour-liquid interface. After explaining the underlying fundamental principles, an industrial case study is presented where hiTRANTM thermal systems were used to increase the duty of a condenser, thereby recovering valuable product.

Speaker Bio

Tom joined CALGAVIN® in 2010 initially as a Thermal Process Engineer. He graduated from Loughborough University with a Bachelor of Engineering (with honours) in Chemical Engineering and a Diploma in Industrial Studies. Before CALGAVIN, Tom had previous experience in engineering quality control for a Curtiss-Wright organisation and as a Process Technician within the process industry for British Sugar plc.

Tom has experience as a Thermal Process Design Engineer, a role in which he was responsible for thermally enhanced heat exchanger designs using CALGAVIN technology. Tom has progressed to take further roles in Sales over the past seven years and is now Sales & Business Development Manager for the company. He is responsible for overall sales and marketing of CALGAVIN’s engineering services and products.

Toms’ typical tasks involve liaising between customers and the company, being a representative at exhibitions and meeting with external clients, new and existing. He also gives technical presentations on the benefits of CALGAVIN technology and contributes to the company’s marketing activities. Recently for CALGAVIN’s future products, Tom also works and facilitates innovation between our academic partners and industrial sponsors to solve problematic fluid conditions not ideal for heat transfer.
