Process equipment disposal

Disposal of Drainage of Process Equipment Contents - When items of onsite process equipment are taken out of service, either individually during plant operation or for general turnaround, means of draining and safe disposal of the residual liquid hydrocarbon contents must be provided. The following are important considerations and terminology in the design ... 

India is second to China in processing e-waste. Seventy percent of the e-waste processed or disposed of in India is believed to originate abroad, with Delhi as its primary destination. Bangalore handles more that is domestically produced India by itself produces 400,000 tons of e-waste annually. With only three facilities currently existing in India to properly handle e-waste, the overwhelming majority goes into the informal sector. As in China, unwanted electronic equipment is seen as worth money, and sold by households or businesses to doorstep collectors.

Whereas the microprocessor controls an individual basic operation, the central computer, which has all the analytical procedures held in its memory, controls the particular analytical procedure required. At the appropriate time, the central computer transmits the relevant set of parameters to the corresponding units and provides the schedule for the sample-transport operation. All units are monitored to ensure proper functioning. If one of the units signals an error, a predetermined action, such as disposing of the sample, is taken. The basic results from the units are transferred to the central computer, the final results are calculated, and the report is passed to the output terminal. These results can also be transmitted to other data processing equipment for administrative or management purposes. The central control is, therefore, the leading element in a hierarchy of... 

The closure activities at J AC ADS consist of decontamination and removal of process equipment and building structures and some soil removal and disposal. Although no requirement for groundwater treatment is anticipated at Johnston Island, other CSDP disposal sites might require groundwater treatment, which would affect the closure process and the ultimate postclosure monitoring at those sites. 

How does a certification process according to the "Certified Chemical Leasing" standard work TON/ SOD Management Service does not take action on its own account. All partners in a Chemical Leasing project can commission TOY SOD to carry out certification, e.g. chemicals producers, process equipment manufacturers, users of chemicals, disposal and recycling companies and many more (Fig. 2). 

After a careful study of existing process trains and options available, it was decided to install a coalescer unit downstream of all major process equipment to treat the produced water before it is injected uuo the disposal formation. As part of this project, a few major modifications were carried out toihe equipment in the process train. 

In many homogeneous catalyst-based industrial processes efficient recovery of the metal is essential for the commercial viability of the technology (see Section 1.4). This is especially true for noble metal-based homogeneous catalytic reactions. Apart from economic reasons spent catalyst recovery is also essential to prevent downstream problems, such as poisoning of other catalysts, deposition on process equipment, waste disposal, etc. Several different techniques are being followed industrially for the recovery of the catalyst from the reaction medium after the end of the reaction ... 

The choice of the decolorization method depends on many factors and each refiner must analyze his own requirements. The principal factors to be considered are the cost of adsorbents, cost of process equipment, labor, water, energy, and waste disposal. Multiple treatment by several different decolorizing methods is common in the sugar industry and is an economical way of ensuring good quality. 

Because of the high costs of waste disposal and treatment, regulatory pressures, and concerns about legal liabilities, industries are scrutinizing their hazardous-waste-generation practices. This applies not only to process wastes, but also to wastes from the cleaning of process equipment. 

The Air Quality Control Systems (AQCS) using lime/limestone wet scrubbing have three basic types of chemical process equipment (1) scrubbers, (2) reaction tanks, and (3) solid-liquid separators, in addition to several auxiliary pieces of equipment such as pumps, demisters, and reheaters. The SO2 in the flue gas is transferred into the liquid in the scrubber, the sulfur in the liquid is converted to solid calcium sulfite, and calcium sulfate in the reaction tanks and solid calcium sulfite and sulfate are separated from the liquid and disposed from the solid-liquid separators such as clarifiers, vacuum filters, and ponds. 

These waste materials, termed secondary wastes, pose a significant planning challenge in regard to considerations such as the operational parameters that process equipment must satisfy, the storage capacity needed for the materials, and whether offsite disposal is advisable. These considerations in turn affect how long and in what manner the facility will need to be operated, including the amount of time needed for closure.
