Use of Process Analytics for Cracking Processes in Refineries

ثبت نشده
چکیده

try (HPI), cracking is the process whereby complex organic molecules (e.g.heavy hydrocarbons) are broken down into simpler molecules by the breaking of carbon-carbon bonds in the base material. The rate of cracking and the nature of end products strongly depend on the temperature and presence of any catalysts. Process automation equipment including gas analysis instrumentation contributes essentially to control and optimize cracking processes. Siemens Sensors and Communication, a leader in process analytics, has proven worldwide its competence to plan, engineer, manufacture, implement and service analyzer systems for use in cracking plants.

REVAMPING OF GAS REFINERIES USING AMINE BLENDS

Abstract: The use of mixed amine system in gas treating processes is increasing today. For natural gas sweetening purposes, mixed amines are typically mixtures of MDEA and DEA or MEA that enhance CO2 removal while retaining desirable characteristics of MDEA such as reduced corrosion problems and low heats of reaction. In this work, a process simulator was used to predict the performance of an I...

Controlling Corrosion in Amine Treating Plants

The causes and the prevention of carbon steel corrosion in amine systems are reviewed. The corrosive agents are acid gases, oxygen, heat stable salts, amine degradation products, and, in refineries, gas contaminants such as ammonia and hydrogen cyanide. Corrosion mechanisms are provided for carbon steel exposed to amine solutions and for amine regenerator overhead systems containing aqueous con...

بررسی استخراج آسفالتین از باقیمانده های سنگین نفتی با استفاده از حلال‌های مایع

In the 1970s, regulations in some countries forced users of heavy residue to limit pollutant emissions at industrial sites, also forced producers to upgrade their heavy products for export and domestic use. For this reason Iran as a producer, exporter and consumer has to develop new upgrading processes. The most common processes for upgrading heavy oil are catalytic processes, but existence of ...

Design of Oil Refineries Hydrogen Network Using Process Integration Principles

This paper describes the application of process integration principles to the design of oil refineries hydrogen network. In this regard, a design hierarchy as well as heuristics and required guidelines are proposed. The recommended rules compensate lack of procedure to the design and make the design process easier. The guiding principles of the design are based upon pinch technology and ext...
