Теплоэнергетическая интеграция блока гидроочистки сырья установки Л-35-11/600

Abstract

As a result of the pinch method is used to heat the new system and presented a workable, cost-effective energy technology block diagram of hydrotreating raw technological scheme of the installation L-35-11/600. Obtained a comparative analysis of existing hydrotreating process raw materials and integrated process. The introduction of this scheme would reduce the reconstructed energy intensity of hot utilities 2383 kW, and the cold – to 2615 kW, which accounts for 58 % of hot utilities and 52 % cold utilities. It is shown that the economic potential for energy savings available after the integration process is 703528 USD. The payback period of the proposed renovation project is approximately 7 months.
