This work investigates the possibility of ammonia low potential heat utilisation with use of Process Integration methodology. The two operation modes are considered. The first one is the use of ammonia gas super-heating and partly ammonia condensation. The low condensation temperature of ammonia is limiting the low potential heat usage. The second option is introduction of ammonia additional compression to increase the temperature of ammonia condensation. The low potential heat consumers are the hot water supply system, air pre-heating system and air heating for the fans. Copyright © 2012, AIDIC Servizi S.r.l. Source

The possibility of ammonia low potential heat utilization was studied using Process Integration methodology. Two operation modes were considered, i.e., the use of ammonia gas super-heating and partly ammonia condensation. The low condensation temperature of ammonia limited the low potential heat usage. The low potential heat consumers include hot water supply system, air pre-heating system, and air heating for the fans. The application of additional ammonia compression would satisfy the requirements of all cold streams heating by the hot streams without using the utilities. This is an abstract of a paper presented at the CHISA 2012 - 20th International Congress of Chemical and Process Engineering and PRES 2012 - 15th Conference PRES (Prague, Czech Republic 8/25-29/2012).

This paper upgrades the Total Site integration methodology, when accounting for a trade-off between capital and heat recovery by selection of optimal temperature levels for intermediate utilities and therefore, decrease capital cost. Heat transfer area for recuperation in Total Site is a two-fold problem and it depends on the Sink Profile on one side and on the Source Profile on another. The resulting temperature of intermediate utility is a result of a trade-off since the heat transfer area on Source side is decreasing, when temperature of IM is decreasing, however increased on Sink side. In the opposite higher intermediate utility temperature leads to higher area on the Source side and lower on Sink side. The temperature of each intermediate utility may be varied between specified lower and upper bounds subject to serving the Sink and Source Profiles. © 2013, AIDIC Servizi S.r.l. Source

The process of benzene distillation and process of coal tar distillation being typical for East European countries is analyzed in this paper. The pinch analysis method was selected to perform a reconstruction project. According to principles of pinch analysis, new network diagrams are designed and capacity of heatexchange equipment is calculated. The using of «Total Site Profiles» showed the feasibility of heat pump integration. Heat pump integration allowed to reduce the external hot utilities usage on 368 kW and cold utilities usage on 368 kW. This project let to decrease the external hot utilities usage on 23 % and cold utilities usage on 24,13 %, and also offered the way of step-by-step retrofit of the plant. © 2013, AIDIC Servizi S.r.l.

The article considers the primary oil refining unit AVDU A12/2 in the mode without vacuum unit. In this paper carried out extraction of data on process flows and equipment, tabulated streaming data. It is performed modelling of primary oil refining unit in the software package Unisim Design to refine the data. It was determined the potential energy savings through the using methods of the pinch analysis, done the project of reconstruction of AVDU A12/2 with the modelling in program Unisim Design to confirm the performance of the project. The amount of heat loss in the heat exchange equipment and pipes was calculated, have developed a method for the accurate determination of the payload tube furnaces. © 2013, AIDIC Servizi S.r.l.
