TL;DR: In this article, the authors proposed to reduce cost of equipment and improve economic efficiency by subjecting raw gas containing H2S to combustion reaction in reactive combustion furnace, sulfur removing process, contact catalysis process, water separating process and H 2S separating process.
Abstract: PURPOSE:To reduce cost of equipment and improve economic efficiency, by subjecting raw gas containing H2S to combustion reaction in reactive combustion furnace, sulfur removing process, contact catalysis process, water separating process and H2S separating process CONSTITUTION:Raw gas 51 containing >=80wt% H2S heated by a raw gas heater 2 and oxygen enriched air 53 containing >=80wt% oxygen are fed into a reactive combustion furnace 4 and subjected to combustion reaction Resultant reacted gas is cooled to below 700 degC within 03sec in a exhaust heat boiler 5 and most of element sulfur is separated in a sulfur condenser 6 to recover liquid sulfur 54 Next, generated gas in the separating process is heated by a heater 7 and reacted in a catalytic reactor 8 to obtain H2S Next, condensed water is separated through a cooler 9, a water cooling tower 10 to obtain crude H2 gas 56 Next, the gas 56 is fed to an absorbing tower 13 and introduced to a H2 recovering equipment 27 through gas pool 23, compressor 24, cooler 25 and drain separating drum 26 and then treated to purify thus hydrogen 59 is recovered

TL;DR: In this paper, the authors conducted a theoretical study on the application of solar air heater for preheating the air of broiler house and showed that the proposed heating system can save gas usage as much as 613.06 kg per harvest cycle, however, the heating system requires additional electrical energy to operate the fan/blower, amounting to 700.66 kWh per crop cycle.
Abstract: Theoretical studies have been conducted on the application of solar air heater for preheating the air of broiler house. The air heating system of broiler house was use a gas air heater and equipped with rocks bed as the thermal storage medium. The study was conducted for the broiler house with the capacity of 30,000 chickens, which is a house with a size of 100 m x 12 m and has two floors, each floor with a capacity of 15,000 chickens. This study aims to determine the potential amount of savings the use of LPG and operating costs of heating chicken coops during the brooding period (2 weeks of starting the chicken farm) on a chicken coop that using the additional solar air heater and heat storage medium compared to air gas heater only. The study shows that the proposed heating system can save gas usage as much as 613.06 kg per harvest cycle. However, the proposed heating system requires additional electrical energy to operate the fan/blower, amounting to 700.66 kWh per crop cycle. The operational cost savings of the proposed heating system is IDR 6,066,358, - per crop cycle (the calculation basis as of November 2015).

TL;DR: In this paper, an exhaust gas from a combustion apparatus is reduced to a dew point or less and, thereafter, heated and discharged into the atmosphere as well as the waste heat of said exhaust gas is utilized in the sea water desalting.
Abstract: PURPOSE:To prevent the air pollution as well as to contrive to conserve energy by a method wherein a temp. of an exhaust gas from a combustion apparatus is reduced to a dew point or less and, thereafter, heated and discharged into the atmosphere as well as the waste heat of said exhaust gas is utilized in the sea water desalting. CONSTITUTION:An exhaust gas exhausted from a boiler 1 is supplied to a gas heater 7 through a heat exchanger 5 and a dust collector 6 to heat the exhaust gas discharged into the atmosphere from a chimney 9 as well as heat the sea water pumped up by a pump P3 in a sea water heater 8 and said exhaust gas itself is cooled to a dew point or less of water and SOx to remove moisture and SOx therein. Moreover, said exhaust gas is sent into the gas heater to be heated and discharged into the atmosphere from the chimney. On the other hand, the warmed sea water heated in the sea water heater 8 is supplied into a multistage flash evaporation chamber 10 and heat exchanged with a cold sea water pumped by a pump P4 to form a condensed water and this condensed water is used as water for utility.
