â  performance and capacity of sulfur recovery unit (sru) are greatly affected by the h2s:co2 ratio of the acid gas stream. the acid gases in iran contain around 35 mol% h2s and 60 mol% co2. this low concentration of h2s calls for more complex sulfur plant, larger equipments, and higher costs. acid gas enrichment processes (age) is run to upgrade low quality acid gas collected from gas treating...

the aim of this study was to determine the effect of different dietary levels of walnut leaves powder and vitamin e supplementation on blood antioxidant status, production performance and egg quality characteristics in commercial laying hens. a total number of 216 leghorn hy-line w-36 (70 week old) strain laying hens used the completely randomized design were divided into 6 groups with 3 replic...

Improved grain protein quality through fertiliser management has potential benefits for growers and feed processors. Stable high quality grain is demanded by feed processors to facilitate grain handling and to reduce the cost of additives in feed formulation. In this experiment we examine the potential gains from altering grain protein quality with fertiliser management. A factorial experiment ...

Anabolic implants are routinely used in the finishing phase of beef production to improve animal performance and feed efficiency. Implanting during the feedlot phase on average increases ADG 18%, feed intake 6%, feed efficiency 8%, carcass weight 5%, and ribeye area 4% compared with nonimplanted controls. Implants reduce the cost of beef production, which is important given current high feed co...

DCMD presents an opportunity to achieve desalination using low-grade waste heat and highly saline feed waters, where it may be economically competitive with RO, besides providing a very high quality product that could be used for boiler feed water and without the corrosion problems associated with metal based evaporators. Combined with high packing density polymeric heat exchangers, DCMD may al...

Short-term production plans are the basis for operational mine production schedules. They concentrate on making long-term mine plans operationally feasible. Furthermore, some variables such as ore grade and tonnage govern mine production systems and cause uncertainty in the supply of raw materials to the mills. Due to the quality variation of material, short-term production optimization is an u...

the experiment was to study the effects of replacing soybean meal by rubber seed meal on growth, economics and carcass characteristics of broiler. a total of 150 day-old commercial broiler (cobb-500) was reared for a period of 35 days. there were five treatments including t0 (without rubber seed meal), t1 (10% rubber seed meal), t2 (20% rubber seed meal), and t3 (30% rubber seed meal) and t4 (4...
