    LDPE and Copolymers - Outlook
    LDPE and Copolymers: 60 + years later, not yet time for a retirement plan – The recent capacity announcements in China while sending a strong signal of market acceptance may also alter the global trade flow by reducing the China’s dependence from imports and accordingly require a rebalancing of trade flows. The growth and developments of coex films adopting materials like mLLDPE, make LDPE and essential ingredient in the new formulations to sustain processability and so reconfirming the need and survival of an old material in advanced applications. The increasing pressure from institutions towards increasing mechanical PCR recycling as well as reduction of use of some applications, create new challenges requiring producers to reformulate their product slates. Lastly the rekindling of co and terpolymers continue to lure interest towards the utilization of autoclaves to produce advanced and more lucrative polymers.

    To maximise conversion of feed gas to 1st Quality product in a cost-effective manner
    Objective To maximise conversion of feed gas to 1st Quality product in a cost-effective manner The 1st Quality tolerance band for LDPE polymer is effectively dictated by the polymer processor who demands very small batch-to-batch variations, in order to make goods fit for purpose with minimal wastage. This scenario has always put a strong challenge on the polymer producer. Today the accepted 1st Quality band is 5%. What are the choices for the polymer producer? Blending offers a great deal. The whole of the make can be utilised but the downstream processor will not be pleased when the polymerisation process has suffered from an erratic/extended grade change or an uncontrolled excursion. The 5% tolerance makes out of specification batches a finite probability and therefore calls for a more advanced control system that can work whilst the product is changing. How? We build an off-line simulation of the polymerisation and check it against the actual plant for each grade change. We use the simulation to determine limits of stability and so develop safe sequences that can be progressively optimised for maximum safe rate of transition. Can we achieve the objective in full? Let’s answer that one by looking at the simulation of the LDPE process.

    Selecting the best control strategy for catalyst pumps
    Comparison of different control systems on hydraulic driven catalyst and comonomer pumps An accurate controlled and constant bump less flow of catalyst to the reactor is a major criteria for a stable process and reactor temperature. High fluctuation of high pressure volume flow lead to high fluctuation of the reactor temperature and limits therefore the productivity of the plant. Therefore any improvement in the pump behavior is an improvement to the process stability. The “traditional” switch over pump is state of the art, but more and more closed loop control pumps come on the market. Several control concepts, such as traditional double-acting and double-acting pump with open-loop and closed-loop, as well as synchronized moving double-acting are used worldwide. Furthermore the Phased-flow technology is coming more and more into the market. A comparison incl. their advantages and disadvantages are pointed out.

    New Life For Aging Assets - General Overhaul for LDPE Compressors
    New Life For Aging Assets General Overhaul for LDPE Compressors Burckhardt Compression also serves customers as a general contractor for compressor projects. This paper shows best practices between the supplier and the compressor operator. Important steps like finding the best solution, scope planning, deployment of well-trained manpower, logistics, repair works in own shops and - where necessary - sub-contracting are outlined in this success case. The concept is: a compressor manufacturer with a strong service focus can meet all customer needs as a single source supplier. Implementation of the customer's requirements and harmonizing of the interface between the 2 parties are part of the Burckhardt Compression package. A particular strong point is the methodical process for finding the best technical and commercial solution. The example in this paper is based on an old OBC compressor. The case also reveals how solutions were found during shutdown and between milestones as well future development of our service activities

    Best practice in retrofitting PAG Technology Lubricants
    White Oil Technologies, currently available for Hyper Compressor lubrication, have unsurpassed performance compared to current PAG Technologies for the same application. Both performances tests and field tests consistently demonstrate that using a new White Oil Technology lubricant for Hyper Compressors will help to extend the cylinder lifetime and have flawless operations. In this presentation we’ll explain the procedure to switch over an Hyper Compressor form PAG lubricant to the New White Oil Technology, assuring the safety of operation minimizing the risk of cross contamination and reducing the start-up time.

    Decomposition at Autoclave reactor at B-unit in Braskem PE3 Camaçari, Brazil
    Decomposition at Autoclave reactor at B-unit in Braskem PE3 Camaçari, Brazil In November 2018 a decomposition reaction occurred in reactor A of unit B of the Braskem PE3 plant during the pressures rise step to start the plant. The investigation identified as root cause the presence of occluded oxygen in the resin due to the opening of the heated reactor, without nitrogen atmosphere and with the presence of residual resin during the replacement of the rupture disk. The presentation discuss the chain of events which led to the decomposition and the root cause analysis of the incident. Additionally, actions taken to prevent the reoccurrence and safety barriers in place are described.

    Strategies for time critical overhauls of LDPE high pressure valves during turnarounds
    The proper function of valves in the LDPE process are critical to a reliable and a safe operation of the entire plant. All valves are in the need of a regular maintenance, mostly during a turnaround. The short and busy period bears the risk of non-conformities, as many plant operators are not as experienced in these work like specialized service suppliers. This lecture presents a strategy to outsource this critical task. The overhaul can be divided into five phases: initiation, basic preparation, detail preparation, execution and project completion. During each phase several mile stones have to be achieved, such as the determination of needed spare parts to execute the overhaul economical, the creation of a detailed overhaul schedule as well as digitalized live documentation and communication during the execution followed by a functional test and certification. The overhaul of the presented case study by the specialized service shop reduced the planning efforts for the client and guaranteed a high quality and economical solution.

    Hyper compressor cylinder life improvement by optimal maintenance
    Hyper compressor carbide plungers are amongst the most critical parts used in the production of LDPE. Although no other material has the necessary and unique combination of properties for this application, the brittle nature of cemented carbide can lead to catastrophic fracture. Although the plunger material and plunger manufacturing process are an essential condition for optimal functioning, correct maintenance is as important in order to increase the life time of the seal rings and guide bush. Plunger manufacturing and plunger maintenance and their effect on cylinder life improvement are discussed in this presentation
