A comprehensive method to assess the technical condition of the pressure equipment of installation operated in the chemical and petrochemical industry, with the use of acoustic emission signal analysis, structure stress field and the degradation st The algorithm for the assessment of the technical condition of pressure equipment of chemical and petrochemical installations, subjected to the long-term operation, allows to determine the damage degree of the material and allows to predict the further development of degradation processes in a function of time. The proposed approach to the problem of safe operation of devices is fundamentally different from the solutions which are currently used in industrial practice. Currently, the supervision of these objects is based mainly on standard non-destructive testing methods. The main limitation of used methods is the lack of the possibility of both examining the object in its entire volume and testing the device in working conditions. Developed algorithm allows to effectively solve current problems in the diagnosis of chemical installations related to the assessment of their technical condition and determination of the conditions for further operation in real time. The algorithm is particularly recommended for monitoring devices in which adverse damages occur due to the long-term operation.

Producing PE125 using GRAFTALEN™ MP-UHHD. Consumer properties, which should be taken into consideration: 1) The unique toughness of the material (the highest rate of all known polymers), namely, Over 160 kJ/m2 2) High abrasion resistance 3) Low friction coefficient (self-lubricating) 4) High resistance to chemically aggressive reagents (media) 5) High creep resistance (geometric stability) Ordinary way - This type of process is quite expensive. Production of PE125, in compounding with bimodal PE100, from 8 to 45% of supermolecular polyethylene is injected, reaching dispersion by multiple compounding (4 stages) in an extruder cascade (XXXXX technology). GRAFTALEN™ MP-UHHD (alloy) is a MELT-PROCESSABLE concentrate of UHMWPE on an HDPE matrix. As HDPE, you can choose the most affordable HDPE (pipe) grade. To obtain polyethylene according to the standards PE125 (with a minimum strength indicator MRS> 13.8-14 MPa, in comparison PE100 has MRS only 10 MPa), a significant improvement in the resistance against hydrostatic pressure is required. For a conventional bimodal HDPE, this indicator is difficult to achieve, since it directly correlates with the impact strength/density indicators and with simple extrapolation, it turns out that the required indicator for PE125 simply does not reach the bimodal HDPE matrix. Another problem - the difficulty in maintaining the geometric stability of the pipe (the thickness at the top of the pipe is often less than at the bottom) due to the sagging effect (the phenomenon of the gravitational flow of a polymer melt). This phenomenon is more pronounced for thick-walled pipes. The specific blend of HDPE with UHMWPE allows solving these problems above.

The technology : Sewage Sludge Extraction (SSE)system for Sludge Dewatering and Thickening is a novel rotary continuous feed mechanical sludge compression devise that simultaneously sucks, and compress sludge mix, on opposite sides of its internal rotating element in a toroidal chamber, to segregate water and sludge into continuous out flow stream through separate channels. Unlike conventional compression technologies this is a ‘Continuous feed Type’ machine , compact, completely enclosed system (keeping sludge sealed from the operators environment to maintain odour free operations) that can operate within necessary power limits and fit within cylindrical space constraints as specified for the Omni -Ingestor to treat rates of 3 litres/higher per second within a compact toroidal chamber with self-cleaning separation screens membranes for long maintenance free operation. The system significant technical advancement and inventive step is that this system is 1st of its kind ‘Rotary Positive Displacement’ devise that permits variable volume control between its rotating elements to deliver a compact & highly efficient, simple continuous feed mechanical compression devise with capability for real time variation in the degree of compression based on the type of sludge and to self-adjust the compression ratio to deliver highly thickened sludge from range of inputs.
