Successful Operation of First Alyclean® Solid Acid Alkylation Unit

 

By Maurice Korpelshoek, Technology Marketing Director, CB&I

Alkylate product remains one of the most favored octane blending components in the refining industry. CB&I and Albemarle have developed and commercially proven a unique solid acid alkylation process, called AlkyClean®, which is the most environmentally advanced and safest processing option to produce alkylate, and an excellent alternative to retrofit existing HF alkylation units. After several years of process development and pilot plant testing, this novel alkylation process was licensed to Shandong Wonfull Petrochemical Group in China. This unique technology is the only demonstrated technology for solid acid alkylation. The results of more than a year of successful operation, together with application of this technology in existing refineries will be discussed.
Alkylate continues to be preferred gasoline blendstock for refiners.
First commercial demonstration of solid acid alkylation technology!
AlkyClean technology is innovative and proven solution for solid acid alkylate production.

Excellence in Turnaround Management

 

BJos Vankevelaer, Vice-President & Cracker Expert, BASF

 

Excellence in Turnaround Management is today a huge challenge in our chemical industry. Identification and implementation of Best Practices play a key role in order to achieve this excellence.

The presentation will guide you through some of the important turnaround processes supporting these Best Practices.

Examples will be mainly based on the last turnaround of the Steamcracker of BASF in Antwerp. During the shutdown of the plant more than 2000 tie-ins were executed in order to achieve the new capacity of the Steamcracker.

Floating LNG – Monetization of Stranded Gas

 

BJos Leo, Director of Business Development, CB&I

The presentation provides an overview of the FLNG initiatives in the market. As a result of the FID decision on Shell Prelude FLNG unit, the energy market has seen a spin off with new activities on the FLNG front. FLNG was till recently the domain of stranded gas fields that could only be monetized by a floating production unit. The FLNG market now has become more robust - financiers, LNG off-takers and energy companies have gained trust by the fact that the first FLNG is actually being built.

As a consequence, more field developers are now embracing the FLNG application. Spearpoint areas for FLNG include Australasia, offshore Brazil and offshore Africa. Apart from a feasible vehicle to develop stranded offshore gas fields, the FLNG units are considered a viable proposition for areas where the realization of a conventional LNG project might be constrained. 

There appears to be an analogy between the market for crude oil FPSOs, floating storage and regasification units (FSRUs) and potentially floating LNG units (FLNGs). For FPSOs and FSRUs, the developments are characterized by a long development period with only a few players being active. Once the new technologies were accepted by the industry, there was a boost in the development within a short time span.

It is interesting to see if FLNG is moving in the same direction.

The presentation will be discussing the market developments, the market drivers and the actual players.

Migrating towards a Plant-Wide Optimized Production Control System

 

By Kris Lauwers, Senior Manager Global Solutions BeNeLux, Rockwell Automation

Today's manufacturers face a complex marketplace and significant pressure to balance multiple priorities centered on globalization, sustainability, innovation and productivity. 

Rockwell Automation understands the realities of the marketplace and has developed an approach to Plant-Wide Optimization that helps manufacturers meet these challenges and capture the opportunities they represent.

In this evening session we will explain how solutions based on Rockwell Automation PlantPAx, our Distributed Control System,  enable Plant-Wide Optimization and help the process industry drive more visibility and flexibility, better production intelligence and higher asset utilization overall.

AIChE / Delta Process Academy Seminar 2016 - Safe start-up of Chemical Plants - Consequences for design, engineering, commissioning and operation

Excellence in safety is the key to address the increasing complexity of industrial production processes and the increase of rules and regulations both in Europe and internationally. One of the priorities is reduction of the number of incidents during start-up and non-routine operation of chemical plants.

25 years lessons learned start-up and non-routine operation of a cracker plant, Geert Vercruysse, BASF

The process safety concept of a plant is determined during the engineering phase of a project. Once the process is started this safety concept will be validated during the life cycle of the plant, based on operational experience and lessons learned from incidents. In the presentation three incidents, related to start up and shutdown, will be elaborated in detail and its impact given on the process safety concept. Further it will be illustrated that similar scenarios can/could occur in different process unit set ups.peration of a cracker plant. Presentation file here

Safe Start-up culture, Marcel Beekman, Fluor

Safe Startup development should be done early in design phase. Considerations for Design, Engineering and Construction phases are discussed:

  •  Company Culture
  •  Design and good operability practices
  •  Safety in Construction
  •  Turn Over Development and Safe Hand Over
  •  Training and familiarization of Operations
  •  Pre-commissioning
  •  PSSR/Operational Readiness
  •  Commissioning and Start-up

Pressure Relief Systems - Thinking Ahead for a Safe Start-up, Bob Siml, Siemens 

It is essential to have a thorough Management Of Change (MOC) process in place to identify pressure relief systems that may need to be adjusted.

Analysis tools can improve the detailed analysis of complex pressure relief systems such as dynamic simulation, QRA and Safety Instrumented Systems. Non-normal operations during start-up should also be considered to ensure proper safeguards are in-place. Further, training, operational procedures and the limitations of relief systems must be considered.

One of the challenges is to consolidate all documentation in a digital platform to facilitate PHA’s and prestart-up reviews. Also addressed are lessons learned in the design, procurement, and commissioning process. Presentation file here

Design considerations for switching a cracking furnace between normal operation and decoke mode, Menno van der Bij, Technip

Design considerations for switching a cracking furnace between normal operations and decoke mode This paper presents the design considerations for the change-over system for the motor operated cracked gas valve (CGV) and decoke effluent valve (DEV) of ethylene cracking furnaces.

A steam cracking furnace regularly requires decoking due to coke formation inside the radiant coil. The furnace is at end of run (EOR) condition when the furnace reaches one of the EOR criteria. Then the furnace has to be switched from cracking mode to decoking mode. During decoking mode, air is introduced into the furnace in order to gently burn off the coke layer.

Switching a furnace from cracking mode (steam-hydrocarbon service) to decoking mode (steam-air service) requires an adequate handling of the involved risks in order to guarantee safety for people and environment.

This paper will explain the functionality and the safety principles of the system resulting from the performed hazard and operability (HAZOP) study and safety integrity level (SIL) review meetings. It addresses how the cracking and decoking mode switch-over can be designed to comply with today’s standards. Presentation file here
