retrofitting crude oil refinery heat exchanger networks in Indonesia

It is widely known that a considerable number of the petrochemical industries are not applying efficient heat exchanger network (HEN) systems to minimise the use of external

Both of these problems can be avoided through the use of heat transfer enhancement in heat exchanger network retrofit. Crude distillation units (CDUs) in crude oil refineries are major consumers of energy because of the

Application to a refinery case study showed that both at the exchanger and network levels, designing for maximum heat recovery using traditional pinch approach results in the least

Aug 19, 2006The use of fouling factors in heat exchanger design and the lack of appreciation of fouling in traditional pinch approaches have often resulted in crude preheat networks that are

Jan 1, 2007Problem decomposition improved heat exchanger network of crude oil refinery by 30.7% in term of the tota l area and by 30.6% in payback period.

The use of fouling factors in heat exchanger design and the lack of appreciation of fouling in traditional pinch approaches have often resulted in crude preheat networks that are subject to

The present work provides a new methodology for optimising crude oil distillation systems. The proposed approach determines the optimum operating conditions for the crude oil distillation

A novel mathematical programming method was applied to acquire the optimal heat exchanger network (HEN) retrofit in the crude oil distillation unit. The mathematical model

Fulltext Crude Oil Fouling: A ReviewFouling in crude preheat train heat exchangers in refineries is a complex phenomenon. Crude oil fouling undergoes different mechanisms at different stages of preheating.

Retrofit of Refinery Heat Exchanger Network under Different Kinds of Crude Oil by Pinch Design Method using Mathematical Programming Warumporn Pejpichestakula, Kitipat Siemanond*a,b

ABSTRACT The use of fouling factors in heat exchanger design and the lack of appreciation of fouling in traditional pinch approach has often resulted badly designed crude preheat networks

It has been reported that about 50% of the total amount of fuel in an oil refinery plant is consumed in crude oil and vacuum distillations. Thus, the heat exchanger networks of crude oil distillation

Pinch analysis has been demonstrated to be a simple but very effective tool for heat integration and optimization of chemical plants. This study uses the pinch principle to retrofit the heat

This study presents developed approaches that could be used for retrofitting of existing heat exchanger networks (HENs) within individual processes and industrial sites to

Application to a refinery case study showed that, at both the exchanger and network levels, designing for maximum heat recovery (e.g., using traditional pinch approaches) results in a

The use of fouling factors in heat exchanger design and the lack of appreciation of fouling in traditional pinch approaches have often resulted in crude preheat networks that are subject to

The performance of the heat exchanger network (HEN) in a plant is an important aspect of energy conservation. Pinch technology and mathematical programming techniques offer an effective

Crude Distillation Unit (CDU) represents significant challenge for retrofitting and energy optimisation as the most energy intensive consumer in a conventional crude oil

Jan 1, 2025For this purpose, a dynamic, distributed mathematical model for shell-and-tube heat exchangers undergoing crude oil fouling (developed and validated against refinery data in
